In this tutorial I will walk to you through creating a simple “Hello World” application using a UITableView for the iPhone.  There are many ways that a Hello World program could be made on the iPhone, I am going to show you the simplest.  This tutorial assumes you have a basic understanding of Objective-C.  Apple has provided a very simple and straight forward tutorial on Objective-C.  You can find it here.

You will learn how to:

This tutorial assumes that you have already installed the iPhone SDK.  If you are unsure how to do this, click and follow the steps.

Creating a New Navigation-Based Application

Open Up Xcode

You will be doing all of your development in Xcode. Then close the Welcome window (if it shows up)

Start a new iPhone OS Project
Click Xcode > New Project and a window should pop up like this:

Make sure Application is selected under iPhone OS and then select Navigation-Based Application. Click Choose… It will ask you to name your project.  Type in “Hello World” and let’s get started.

Learn About the Default Files

What is all this stuff?
There are quite a few files that get added to your project.  At first glance, this looks kind of intimidating.  Don’t worry, we only need to edit one of them. Here is a quick explanation of the different files. You don’t have to read this part but having this many files is what confused me the most when I started developing for the iPhone.

  1. CoreGraphics.framework, Foundation.framwork, UIKit.framework – You guessed it, this is a set of library functions provided by Apple that we use in our application. We use these as includes similar to any other language that includes library functions.
  2. HelloWorld.app – This is your app that gets installed on the iPhone.  We don’t really need to worry about this right now
  3. Hello_World_Prefix.pch – This is another include file that gets compiled separately from your other files so you don’t need to include it on each file. It contains some code to include the data inside the frameworks.
  4. Hello_WorldAppDelegate.h – This is a header file that contains all of our definitions for variables that we will be using.  It’s very similar to a header file in C or C++;
  5. Hello_WorldAppDelegate.m – All of the magic starts here.  Consider this file our starting point for execution.  The main.m file invokes this object.
  6. Info.plist – This contains various meta information about your program.  You won’t really need to edit this until you are ready to start testing on the iPhone
  7. main.m – Like most programming language, this file contains our main function.  This is where execution begins.  The main function basically instantiates our object and starts the program.  You shouldn’t need to edit this file.
  8. MainWindow.xib – This contains the visual information of our main window.  If you double click on it, it will open in a program called “Interface Builder”.  We will get to this a little later.  Just on thing to note is this file does not contain any code.
  9. RootViewController.h, RootViewController.m - These are files for a view controller that gets added to our main window.  Basically, Apple has already created a simple interface when you clicked on Navigation-Based Application. Since most navigation-based applications use a Table View, Apple has provided it for us to use.
  10. RootViewController.xib – This is a view that Apple has provided that emulates a table.  It has rows and columns.  We will be displaying our “Hello World” text inside one of these rows
Now, all of these files together create a basic program.  Go ahead and click on the Build and Go button at the top of Xcode. Make sure the drop-down on the top left says Simulator | Debug, this tells Xcode that we are testing on the iPhone simulator.
You will see the iPhone simulator start and your program will launch.  It’s not very interesting at the moment.  All it shows is the Table View that Apple has added for us.  So what we are going to do is add a row to this table view.

Update the UITableView Cells to Display “Hello World” Text

Let’s write some code
Start by opening RootViewController.m. This is the view controller that Apple added to our main view.  All of the functions you see already created in here are functions that have been overridden from the Table View super class.  Since we are editing a table, all of these functions will be related to editing a table.  So find the function called numberOfRowsInSection.
This function tells the application how many rows are in our table.  Currently, it returns 0. Let’s change that to return 1. This will tell the application that we want 1 row in our table.  Now go down to the function called cellForRowAtIndexPath. This function gets called once for every row.  This is where we define what content to display in a given row.  In this case we want the row to be a string that says “Hello World”.
What this function is doing is creating a new cell object and returning it.  The code between the i(cell==null) block checks to see if we have created a cell before, if not build a new cell, otherwise use the one we created before.  This helps in performance so we don’t need to build new cells each time we visit this function.  So right before the // Set up the cell comment add the following code:
[cell setText:@"Hello World"];
We are basically calling the setText method of the cell object and pass in the string “Hello World”.  As you should know from reading Apples Objective-C overview, strings begin with an “@” symbol.
That’s it!  Click the Build and Go button again to launch the iPhone simulator.  You should now see a screen like this:
You can now use this code as a base for creating a Navigation Based application.  In a later tutorial, I will detail how to populate this table view with an array of strings to create navigation for a simple program.  If you get lost at any time, you can download the sample code for this program here hello-world.  I hope you enjoyed the tutorial and if you have any questions, feel free to leave them in the comments. Happy Xcoding!

    Thanks for such a nice tutorial.

    Sir, I am trying to display image and Text both in my UITableViewcell
    where I am able to display both, but able to make the size of cell equals to the size of the image, as image size is large enough.
    Here is my code, please check it.

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *MyIdentifier = @”MyIdentifier”;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
    cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
    }
    /**************************************************/
    NSMutableArray *array = [NSMutableArray arrayWithObjects: @"Aquarius", @"Aries", @"Cancer", @"Taurus",@"Capricorn",@"Gemini", nil];
    //index path is definately required
    int x=indexPath.row;

    NSString* imag1=[[NSBundle mainBundle] pathForResource:[array objectAtIndex:x] ofType:@”png”];
    UIImage* myImg=[[UIImage alloc] initWithContentsOfFile:imag1];

    LOL, thanks man. When I apply, I’ll be sure to put you as a reference.

  • demuro1

    WOW this was awesome. I’ve been trying to make something like this work for a few days now based off of a tutorial from another site and it just keeps crashing the simulator. Thanks a million

  • http://www.appliedrelevance.com George Everitt

    I have 20+ years hard-core programming experience – none of it with Objective-C or Cocoa. I’m on week 2 of heavy-duty cramming to write an iPhone app, rewiring my 40+ year-old synapses to deal with Apple’s flavor of MVC. Last time I spent this much time with a new language was 1996 when I learned Perl. Wish me luck.

    Thank you for this site – it is the best resource that I’ve found so far. If Apple doesn’t hire you, give me a shout.

  • http://geekcore.com.au Pat

    Awesome!
    I’m in the process of learning how to program on the iPhone, and this is the first tutorial that ive ever seen that delivers what it promises!
    My only suggestion would be for a seperate tutorial that go into even more detail about the individual files that are created when you first make an app. (this is more for a sense of completion, as your brief descriptions are fine, as is)

    Otherwise, an awesome tutorial! This site is bookmarked, and sure to become one of my “morning checking spree” websites, up there with tuaw.com, kotaku.com.au, and engadget.com!

    well done! :)

    Nice blog. I wish I had found this a few weeks back. I have read something like 700+ pages of SDK PDF documentation pages from Apple’s iPhone Dev section of the Apple web site. You could have shaved some time off my learning!

    I thought I would share some comments on your “beginning” tutorial that will hopefully alleve newbie fears for the commonly held belief that iPhone application development has a steep learning curve. It does feel steep if you are unfamiliar with the language and the tightly coupled SDK. Newness on two “fronts”.

    This is mainly meant for folks not completely new to programming.

    First, read a good Objective-C overview or tutorial that is not on the Apple website. One I found useful was:

    http://cocoadevcentral.com/d/learn_objectivec/

    The Apple overview on Interface Builder (IB) for iPhone development is not too confusing but may be a bit too much. You may want to browse it a little or find some third-party tutorial out there. Brandon does delve into it here but thus far he mainly has you complete steps within it but does not really explain what those steps are actually doing. Although, to be fair, I have not gone through every single tutorial here yet.

    Then go straight to good iPhone application tutorials such as on this site. Just jump in and get your feet wet.

    Delve deeper into some Apple Objective-C documentation to clarify a few language things (such as memory management).

    Finally, refer to the Apple SDK documentation to clarify SDK properties and methods/messages you see in the tutorials (although Brandon is covering the ones he uses pretty well). Also good to discover some you don’t see mentioned but could come in handy.

    Keep this in mind when reading Apple documents:

    The Apple iPhone SDK documentation, as well as their documentation on Objective-C and such, are written very concisely and almost in a circular reference fashion. This is necessary in programming docs but seems to be quite excessive in this case due to the writers being pretty thorough. Forward references, so to speak, abound in these docs (or I read the documents in the wrong order!).

    To read, no, to understand them, you must read a doc, understand part of it, scratch your head on the rest of it, and then go read more docs on similar topics. With the new docs read, you will have a few “a-ha” moments but you will have bigger “a-ha” moments when you go back to the previous doc and re-read parts of it.

    Be sure to read in a calm, quiet atmosphere when reading Apple docs. I can read ASP.NET or Ruby stuff at a party and almost understand it perfectly but for some reason, this Objective-C/Cocoa hybrid takes concentration. I think it is the dang doc writing style.

    Once you are comfortable, there are a whole slew of sample applications on the Apple iPhone dev web site. The “TheElements” one was pretty straightforward as are a few others.

    This was more of a “pat on the back” to those who may start feeling helpless or lost at some point (prior to discovering awesome tutorial sites like this one). If you came to this site but are about to give up, don’t. Follow my advice above and rest easier.

  • http://www.ChipAndKim.tv Chip McAllister

    Hey Brandon . . . THANK YOU!!! Man, I was SOOOOO overwhelmed before finding this site. I was ready to give up learning to program for the iPhone all together. I was a programmer about 8 years ago (Dynamic Database Application Developer using .ASP’s mostly with SQL Server and even Oracle sometimes). However, now that I am getting back into it, I am going to bite the bullet and familiarize myself with OOP, specifically C, C++ and everything pertaining to building iPhone apps. I have finished all of your tutorials and am STILL extremely fuzzy on most things . . . HOWEVER, your tutorials give me tremendous glimpses of hope that I will become proficient at developing iPhone Apps soon. If you know other (NON-CRYPTIC-APPLE DOCUMENTATION) sources for me to come up to speed like websites, books, online training courses or even training courses in Southern California, please let me know. In parting, I must say again THANK YOU, BRANDON . . . You have been a great help to me.

    One question: testing application in simulator is great during development process, but is there a way how to upload it to the real device and test it on real iPhone/iPod touch? Or is the AppStore the only way to do it?

  • Surane

    Thanks,

    Juste for fun :

    replace

    [cell setText:@"cell"];

    with

    [cell setText:[[NSString alloc] initWithFormat:@”Cell : %d”,indexPath.row]];

    You’re doing a wonderful job.

    This one is way too simple than Apple’s Hello World which made me nervous about Objective-C!

  • Deus.!

    Thankyou!!!

    Wonderful tutorial, really the best I have seen. I like how you explain the code. This is the best hello World I have seen out of about 8 that I have already seen.

    Brandon, thanks so much for sharing your ideas and tutes with the world.

    Hello,

    nice blog and thanks for your tutorials.

    I want to ask one thing; is it possible that I can reorder the rows in tableview at runtime?

    Waiting for a positive reply.
    Thanx

    @Rana,

    Are you talking about letting the user re-order them or code to reorder them?

    Great site. I had to pay $40 bucks for a tutorial book when I could have come to this site? Sad.

    Here’s my questions:
    How do I get a UITextView to show up when the Hello World button is pressed. Type slowly, I’m new at this.

    thanks

  • AE

    FINALLY! Someone who knows what they’re talking about. I have a serious doubt that other developers who make tutorials know anything about what they are demonstrating. Notice that the other tutorials never describe what the .m and .h files do. This one does! Other tutorials never describe anything by theory and it takes forever to learn something without theory.

    Good Job!

  • Chris

    Hi Brandon,

    Great tutorial. I’m looking forward to going through them all. Just a couple of things that might get absolute beginners like me a bit tripped up.

    1. “The code between the i(cell==null) block checks to see if we have created a cell before, if not build a new cell, otherwise use the one we created before.”

    I think you meant “the code between the if(cell == nil) block” in this part of the tutorial.

    2. In the screen image where you add “[cell setText:@"Hello World"];”, I don’t think there should be a “|” character after the “;”. This might be a typo when typing return on your keyboard :-) .

    Again, great work and thank you for taking the time out for these tutorials.

    Thanks for your effort! These are the first tutorials where everything is explained in a logical fashion. I am quite familiar with OOP from as3 and I’ve read the basics for Objective C, but still I’ve been struggling with getting started. You have succeed where most other tutorials fall short: maintaining just the right level of detail to keep the reader interested and still able to understand what is going on.

    I’m a teacher myself (as3, php, xhtml, css), so I recognize a job well done when I see it. Thanks!

    Hi there,

    I was just wondering what kind of permission you do before putting your code online ….

    Because I made this litle code, it runs on my XCode 3.1.2 perfectly, and I gave this code(whole project including .xcodeproj) to my friend to run it on XCode 3.1.3 …. and it doesnt compile. it gives bunch of error while compiling like following:

    Checking Dependencies
    warning: couldn’t add ‘com.apple.XcodeGenerated’ tag to ‘/Volumes/swaraj yadav’s Public Folder/TypeWriter/build/TypeWriter.build’: Error Domain=NSPOSIXErrorDomain Code=13 UserInfo=0x36cf230 “Operation could not be completed. Permission denied”
    error: ‘/Volumes/swaraj yadav’s Public Folder/TypeWriter/build’ is not writable
    error: ‘/Volumes/swaraj yadav’s Public Folder/TypeWriter/build’ is not writable
    Unable to write to file /Volumes/swaraj yadav’s Public Folder/TypeWriter/build/TypeWriter.build/Debug-iphonesimulator/TypeWriter.build/Objects-normal/i386/TypeWriter.LinkFileList (You do not have appropriate access privileges to save file “TypeWriter.LinkFileList” in folder “i386”.)

    so I am just wondering if you are doing some setting in your XCode project because I am able to run your code on my XCode , and my friend is also able to run your code on his machine.

    Any help will be deeeply appreciated !

    I’m well-versed in machine language, assembly, PHP, javascript and understand components of ASP and VBasic. But I swear I’ve never had so much difficulty as I’ve had learning how to program for the iPhone.

    Your tutorial was an excellent primer for me, and gives me a foundation to start grasping some core concepts.

    setText: is deprecated in iPhone OS 3.0+

  • Ben

    [cell setText:@"Hello World"]; will still work but

    cell.textLabel.text = @”Hello World”; would be a better choice for people because setText: could be dropped in later versions of the OS

  • http://jcostaman.com John Costa

    Am I the only one who gets the warning: ” warning: ‘setText:’ is deprecated (declared at /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UITableViewCell.h:199)”

  • Scott Calafiore

    No I get that too with the SDK 3.0 like stated above use cell.textLabel.text = @”Hello World”;
    instead of
    [cell setText:@"Hello World"];
    The second code will still work but it is more correct to use the first code. :)

    Hi I have a table view populated by an array of objects called from a database, the database has a column called “sort” that is an integer and I’ve set it up to set that integer = indexPath.row and it updates when I move the rows ,

    Bu I’m having trouble figuring out how to display the objects in the array with that “int” instead of with their PrimaryKey.

    If any one can help please drop me a line at mrburns08x@gmail.com

    Hi interesting post but you forget to mention to change also the code that returns the number of rows …
    It should be in this way in order to works on iPhone SDK 3.0

    // Customize the number of rows in the table view.
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 1;
    }

    thanks for the tut but this whole application structure looks more than redunant. now im forced to live with that. its still easier to create this row table navigation with html/css and javascript.

    setting a row count doesnt look good to me. it would be cooler if they would have provided a xml based output logic for this communistic row design shit.

    thank you very much for your tutorial. Learning something new everyday

  • Scotty

    Very nice tutorials, thanks!

    Can Navigation Controller only be used with Table View Controller, the two seem to be tied together, with the Add and Edit Nav Bar Buttons….

    I’ve been trying to get the Navigation Controller working with other View Controllers and that doesn’t seem to work, it’s always shown with Table Views, is that all you can use, at least as the root view?

    Thanks again.

    Hey Brandon,

    Just getting into this iPhone stuff and your tutorials are working nicely :)

    Thanks very much-

  • Nina

    Hi,
    Im new to xcode.I just founded your tutorials and decided to start from scratch.
    Just by the beginning Xcode giving me an error of ” doesn’t match any valid certificate”. I searched on web and it said I need to validate the certificate on keychain access. I found so many different solutions and I confused. Can anyone help me in this matter please?
    By the way your tutorial is the best I have found so far. It’s about a month that I’ve been looking for a good tutorial.
    Fabulous job. Well done and Good luck.

  • Soundarya

    Nice tutorial for the starters. It helps in getting know-hows of the all the files which are created as part of the templates. Keep on publishing more of such tutorials. Good work!

  • Jose Muanis

    Hi, great for presenting the topic.

    In the last SDK,

    [cell setText:@"Hello World'];

    setText is deprecated, you should use instead:

    UILabel *label = cell.textLabel;
    [label setText:@"Hello World"];

  • Biplav

    Great work. Keep them coming.

  • Maddog2k

    Is it just me, or does this tutorial does not work with the latest “Navigation-based Application” project template from SDK 3.1.2? Any chance the tutorial will be updated?

  • Maddog2k

    Disregard my last post. This demo works with 3.1.2 but there is a trick… you must uncheck the “Use Core Data for storage” option when selecting the Navigation-based Application template.

  • http://www.epicdesign.com.au H

    Nice one, very detailed and short to the point.

    Cheers

  • http://spaquet.blogspot.com iCan

    [cell setText:@"My String"];
    Well, in 3.0 setText is deprecated and should be soon removed from sdk.

    The new way of displaying information is now to use
    [cell.textLabel setText:@"My String"];

    enjoy ;-)

  • j

    Keep writing simple pages like this, then anyone will be able to code for iPhone!

  • http://www.entdyn.com Korky Kathman

    When you do the Build & Run under SDK 3+ this will give a warning that setText is deprecated. What would the new syntax be?

  • http://www.entdyn.com Korky Kathman

    Woops should have read up a few posts first! Sorry!

  • schmicko

    The cell text is now a textLabel and a detailTextLabel.

    you could write:
    cell.textLabel.text = @”Hello World”;

    And … if you change the code just above for defining the cell and replace:
    initWithStyle:UITableViewCellStyleDefault
    – with -
    initWithStyle:UITableViewCellStyleSubtitle
    - then you can add:
    cell.detailTextLabel.text = @”Hello again”;

    here it is all together:

    if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }

    cell.textLabel.text = @”Hallo World”;
    cell.detailTextLabel.text = @”Hello again”;

    hi very nicely explained. thanks for the effort !

  • HeoSuaVN

    Thanks for the tutorial.

  • Stephen Richards

    The setText method of UITableViewCell has been depracated.

    so the line should read:

    cell.textLabel.text = @”Hello World”;

    Are you really doing this for free? You can probably start a professional iPhone dev course of yours. Apple docs can look pretty scary to a newbie.

    Your are really helping a lot of people. Apple should really pay you for doing this.

    Why don’t you have atleast a ‘Paypal Donate’ button on this blog? I am sure many readers would like to encourage you to keep writing these handy tutorials.

  • adam d

    Hello,

    Thank you for making this tutorial however I have encountered an error and I was wondering if you might be able to help.

    [cell setText: @"Hello World"]; isn’t working for me because I have the iPhone OS 4 beta 2 installed and setText is deprecated.

    It tells me to use the property textLabel however I am unsure how to use it appropriately.

    Thank you for your help…

  • adam d

    nevermind sorry,

    cell.textLabel.text = @”hello world”; worked fine, just needed to hunt a little bit!

    [[cell textLabel] setText:@”Hello World”]; also works if you want to make it look more Objective-C-ish.

    [cell.textLabel setText:@"Hello World"]; is also valid.

    I am struggling to make this come up as a View Controller.
    I want to have the main screen have a button that says: “Go”
    and then have it do this Hello World program.

    It is because I am doing something similar, and I already have an applicationDidFinishLaunching in that program…
