Wow, can you believe that it has been almost 3 years since I started iCodeblog!? It seems like just yesterday, That I wrote my very first tutorial in July of 2008. Now, iCodeBlog has multiple authors, hundreds of tutorials, and over 5,000 readers per day!
As you know, a few things (to say the least) have changed since we first launched iCodeBlog in 2008 with the way we develop for the iOS platform. With that being said, …
Today I’m going to show you how to make a static library for iOS. We will make a simple library and use it in a separate project.
What’s a static library
Here is what wiki has to say:
In computer science, a static library or statically-linked library is a set of routines, external functions and variables which are resolved in a caller at compile-time and copied into a target application by a compiler, linker, or binder, producing an object file and …
Guest Bloggers
Hey iCoders! We are looking for some guest bloggers to write iOS tutorials, code snippets, tips, tricks, you name it for iCodeBlog.
How to apply:

3. ???
4. Profit (OK, no profit (yet), but you get exposure(link your blog) AND the good feeling that you are contributing to the …
Learn from Industry Leaders Who Literally “Wrote the Books” on iOS Development
Coming to you direct from Addison-Wesley Professional, which has published some of the leading books in the field, the Voices That Matter: iPhone Developers Conference is taking place October 16-17 in Philadelphia!
Take a look around at all the tech books you have on your physical and digital bookshelves. If you’ve been developing for the Mac, the iPhone and the iPad – chances are good that you rely on books by Steve Kochan, Erica Sadun, Aaron Hillegass and Jeff LaMarche. Even more, you probably follow the Tweets and blogs of folks like Graham Lee, Mike Lee, Matt Long and Chris Adamson. Wouldn’t it be great to meet and learn from these thought-leaders in person? Now you can at the Voices That Matter: iPhone Developers Conference!
It has been quite some time since our last iPhone video game series and now we are ready to start a new one. Â Given the success of our iTennis tutorial series, we will be following along the same line and create a game without using OpenGL ES. Â If you are interested in OpenGL ES programming, check out Jeff Lamarche’s blog, he’s super rad. In this series we will be creating a simple Blackjack game with the following …
Way back when, when everyone was still complaining about Apple’s lack of support for (3rd party) multitasking, there was a simple solution put in place. This solution was known as push notifications.
Push notifications solved many of the issues associated with background processing. For example, when quitting the AIM application, the server could keep you logged in and send you a push notification when a new message arrived. You could then tap on a View button that would launch the app.
This solution is great and all, but it still requires that you have an active internet connection. As of iOS4, Apple has introduced a new type of notification that can be scheduled to fire within the device itself. It requires no complicated server programming, or additional configuration with iTunes. I am talking about Local Notifications.
So, why would you want to integrate Google Analytics into your iPhone application. Duh, for the same reasons you would integrate it into your site. Google has extended their killer analytics platform to include mobile devices including the iPhone and Android devices.
The analytics API gives you some very powerful options to get as nitty gritty as you would like in your application tracking.
Now, that the iPad has been released, I’m sure you are all scrambling for ideas on how to snag a piece of the maket in the imminent gold rush. iCodeBlog is going to help you on your journey with a series of iPad tutorials to come.
Since the iPad uses the same SDK as the iPhone, all of the code under the hood is almost identical. Actually, when looking at the new and changed API classes, you will realize that most of them are user interface related. This is good news for us since we have already been coding iPhone.
While this tutorial is called “Hello World”, it is really much more than that. I assume you already have working knowledge of iPhone/Objective-C programming.
So, let’s face it, MANY applications in the app store are “Clunkyâ€. They have jittery interfaces, poor scrolling performance, and the UI tends to lock up at times. The reason? DOING ANYTHING OTHER THAN INTERFACE MANIPULATION IN THE MAIN APPLICATION THREAD!
What do I mean by this? Well, I am essentially talking about multithreading your application. If you don’t know what is meant by multithreading, I suggest you read up on it and return to this post. Let’s dig in and I’ll give you an example of the problem.
I had some a to shorten URLs for an in-application Twitter client I’m working on and thought I would share my simple solution with you guys.
It’s actually pretty straight forward and can be done in 1 line of code. I have broken it up into several for clarity.
