This is a great tutorial! I was looking for an intro into calling web services with the iPhone SDK, and this was a great starter.

Keep up the great work on this site!!!!

Hi

I was using something similar taking reference from http://kosmaczewski.net/2008/03/26/playing-with-http-libraries/

But this method causes a problem when using on the device. It works fine on the simulator though. I’ve been trying to figure out the reason for sometime now.

The problem with running it on the device is that the content length logged at the server is 0 if you send the SOAP envelope as the body of the request using POST. Any ideas why this would happen though?

lovely background image you got there

Thanks for the tutorial. Just what I was looking for. Just one question (not about the tutorial), how do I setup custom code snippets? Cheers

Hi i have seen many tutorials on connecting a iphone application to a web Service this is one of the best , I want to know how to send parameters to a web service something like , There is a method which adds to given numbers and returns the result , those two numbers are the arguments of function now how to pass those parameters i will be thankful for the reply

sindhu tiwari

i believe NSXMLParser is not available on the device but usable on the simulator. that is why iDeveloper had some issues

How did you set up the text macros? Those look really handy.

hi ,

awesome sample which u have put upon WebServices , but one small query , i am unable to run this sample can anyone guide me from the scratch for how to run this sample .

thanks in advance.

Thnx! This was really helpful for me.

You can barely hear the audio at all… even at full
volume.

*PLEASE* speak into the mic.

Thanks a lot for your great tutorial,
I am writing an iphone application that will consume a .net webservice (basically it will get the list of radio channels with their url and an image)
I wrote the ,net webservice and it is working fine but when I am trying to get the xml data in iphone I see that tags are
not displayed correctly in debugger “” are shown like >< do you have any idea about this?

Thanks for your tutorial ! just what i needed !

Even running the sample code, I get a warning in the method
parser didStartElement:

for the following line (line 100 in sample)
recordResults = YES;

Message is as follows:
warning: assignment makes point from integer without a cast.

Any ideas what this is about? Anyone else seeing this warning?

Good tutorial, well done.

The warning is due to the superfluous * in the definition of recordResults, was:
BOOL *recordResults;

should be:
BOOL recordResults;

Oh, i see! Thanks Uffe!

XML data / SOAP request??

How do we create the XML data / SOAP request

Forget it. Finished reading everything, saw some examples, created the needed soap messages at runtime. Thanks for a great tutorial

Hi! Great tutorial. By the way, i’ve been working on it and i wonder if you could answerme one question. Would it be posible to create a connection at the applicationWillTerminate method and wait for connectionDidFinishLoading to finish?

Thank u!!

Thanks for the useful tutorial…i have tried it. It works great with Web Services developed with Dot Net 2.0 framework. I have to consume webservice developed in Dot Net Framework 3.5, but its not getting any response from the server at the connectiondidfinish delegate method. The HttpConnection Status i m getting is 400 ( bad syntax ).
The webservice is returning data from another web client.
Can you please suggest me something to try.

Thanks for the tutorial..

how do we see the methods by writing ” @url “. what is the shortcut for it

I tried to receive data from a webservice which is almost the same as shown in the example. But I have an issue when coming to parsing the data from the response from the server.

The response looks like this:

string

The issue in this case is that the string that is returned from the server is another XML file, where the format is not as it should be.
The is >
When trying to parse this string with the NSXMLParser function, I am not able to parse it as I want to due to the brackets. Looked for a solution for this, but only found something called “CFXMLCreateStringByUnescapingEntities”. But this give me another problem, something called CFStringRef. I do not know how I can use this function to get the XML format from the string, so it is possible to parse the data and present it in the application.

As I understand the NSXMLParser needs a NSObject, not a string, and my question is then, how can I use the unescaping entities function and use it in the parser?

Thanks in advance.

Saw that a lot of the text is missing in my previous post.
But maybe it is shown in this:

string

The issue in this case is that the string that is returned from the
server is another XML file, where the format is not as it should be.
The is & gt;

This was a great tutorial. Thanks for sharing it!

Hello Dude , Thanks for such a good blog .

My aim is to consume a PHP driven webservice into my Iphone project .. can u provide some stuff on that .. i know that underlying architecture doesnt makes any difference but still for me I AM DUMB IN PHP .. headers and Soap Message will be enough for me ..

Have a wonderful time ahead

Thanks and Regards

Sindhu Tiwari

How would you go about passing username/password if the XML Service was on a secure site that requires HTTPS and authentication?

Hi !
Thanks for this tutorial.
I’m new to iPhone and Apple programming (I come from .NET world) and I can’t believe it’s so complicated to consume web services in ObjectiveC… isn’t there a simpler way to do that ? With Visual Studio I can do that in 30 seconds.
Thanks in advance for your answers.

Hey,
Tutorial is great. I just want to ask, how do you autocomplete the delegate methods?

Hi

Hello :
I used the code posted in this thread. It helped me a lot.
But now I am facing an issue please help me.

and get back some information related to child.
But 0 byte response is received please help me in fixing this issue
Thanks in advance

Excellent tutorial and blog. Its my favorite one now Thanks a ton for sharing your knowledge.

hi there! this is a great tutorial!!

question. what method can i use to return the value in the request below:

string

I see that NSLog(soapResults); returns what i want….but i’m not sure how to use it to catch if/when a request returns “false”, then i want to create a UIAlert telling the user their login failed. thanks!!

Hi guys,

I downloaded the source and tried to open the project file in xcode. I have the latest xcode running (only downloaded it around a month a go).

I get a warning about this project having been saved under a “newer” version of xcode and when it opens the project there are three files that are colored red which it obviously cannot find:

Foundation.framework
Hello_SOAP.app
UIkit.framework

Any ideas?

Sorry – disregard the last post – all works fine.

Thank you very much for this tutorial. Great work.

Hello I am new to Iphone development and your tutorial helped me too much. Thanks for your this tutorial.

Also please let me know how you get code sense window doe delegates for eg in video you typed “@url” and then delegate code window will appears how?

Thanks in advance.

Well i figured out how to read one value from an xml file from ur tutorial, but right now at the moment im doing a project that needs me to traverse through a tree of data and pick out certian keywords and display their values and since i learned ur way of retrieving xmldata i thought i come to you first.
-thanks

I have used this example in my application. Its working properly on simulator. but not working on iphone device. Its giving “Connection error”. I have checked for wifi connection. its working properly.

If you are working on PHP and want to create a PHP server t respond to the SOAP requests, I have written a script, which uses NuSOAP library. You have to download it from sourceforge : http://sourceforge.net/projects/nusoap/files/

In the obj-c code replace the soapmessage creation code with the following: Its easy to understand, sending the name inside name tags placed inside Hello tags.

NSString *soapMessage = [NSString stringWithFormat:
@"\n"
"\n"
"\n"
""
"%@\n"
"\n"
"\n"
"\n", nameInput.text
];

Also replace the target URL with your php file URL:
NSURL *url = [NSURL URLWithString:@"http://192.168.1.23/iPhone/index.php"];

Now the PHP script is here. My server on Windows, I did it accordingly. Alter the NuSOAP include path as you placed on your computer.

configureWSDL(‘Hello’, ‘urn:Hello’); //The 2nd param is the namespace & is optional

/* register the method to expose */
$server->register(
‘Hello’, // method name
array(‘Hello’ => ‘xsd:string’), // input parameters
array(‘HelloResult’ => ‘xsd:string’), // output parameters
‘urn:Hello’, // namespace
‘urn:Hello#Hello’, // soapaction
‘rpc’, // style
‘encoded’, // use
‘Says hello to the caller’ // documentation
);

/* Define the method as a PHP function */
function Hello($name){
return ‘hihihi… ‘ . $name; // return string inside HelleResult tag
}

/* Use the request to (try to) invoke the service */
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ”;
$server->service($HTTP_RAW_POST_DATA);

exit();

?>

hope it help somebody..

SORRY..!!!!!!

all the strings are stripped off…

Hey Brandon/Dave,

Thanks a lot for putting this tutorial up. Would it be possible to get a tutorial or a brief snippet of how to create and launch the web-service which you have used here.

Thanks,

Hi,
great tutorial for beginners, thanks for it.
But whats realy awesome is code completion feature I have seen in the video.
The author wrote ‘@url’ then pressed some keyboard shorcut and then got list of few delegate method definition to choose.
I only know shortcut ESC (or ctrl + esc), but it is not working this way. Can author or anybody tell me, which shorcut is that?
Also escaping xml string at beginning part of the video was also faster that I would expect, does anybody know how to do this magic things in XCode??
Thanks much.

Anyone got a php server that will work with this??

Thanks for the example code. Easy to understand and modify! Got it working with a new web service in no time at all. Great Job!

Hi, I’m trying to display a loading view while the web service is working, but I can’t succeed. I started with the source project we can download at the end of this article. Then, I added a simple LoadingView (UIView) with an UIActivityIndicatorView. I would like to display it just before calling the WS, then remove the loading view when the WS process is over. Any idea?

Hello,

It seems that the video isnt working? Is there something wrong on my end?

I have created some wrapper classes and an objective C .NET dataset object class to easily incorporate passing datasets to your iphone app check it out!

http://grabalife.com/2009/10/19/using-net-web-services-and-dataset-objects-in-your-iphone-app/

I’ve tried to put this example in a class to do a login via web service. I get my user id and password from the NSUserDefaults. I build the SOAP envelope and get my validated userId back in the web service…that works!!!

In the parser didEndElement method I have the value I want (userId) in soapResults and am setting it like this:

myUserId = [[NSString alloc] initWithString:soapResults];

I have this as a property in the class .h file as:

@property(nonatomic, retain) NSString *myUserId;

I’d like to be able access that value by my view controller class that creates the instance to use the web service as:

LoginWebService *loginWebService = [[LoginWebService alloc] init];

[loginWebService logUserIn];

Right now it returns void and I try to get the value from the myUserId property. This does not work.

I also tried returning a string from the logUserIn method where the SOAP message is defined…again no luck.

I apologize if I’m missing something obvious…I’m coming from the .Net world and trying to pick this stuff up.

Please provide some help or an example of wrapping your code into a class that can return a value as a result of the web service having been contacted, parsed and return a string to the instantiating class (in my case a userId). Any help would be appreciated, my head is a bloody stump from beating it against my Mac Book.

Thanks in advance.

my webservice is returning array and it shows #[] only if I am returning string from service it is shown properly. what needs to be done to get response array in client from server.

Hi John, Please could you provide the code, so access to access a login web service.
I am having a login web service, but still i did not get how to pass paramters like username and password to the web service.and also how to capture the results in the application.
Please help.. I am very new to iphone application development.

Hello thank you for taking the time to
create this tutorial it helped me alot.
I am having one problem, getting an
error when trying to access the webservice
asmx file through the internet. When I try and
access it via the internet I get an
xml parsing error. When I right click
the file and select view in browser it opens
fine on the server. When I try and
open the file on the server through
port 8000 the port I am using for incoming
internet connections I get the same error.
What am I doing wrong?

Nice tutorial. Thanks.

John,

Maybe I’m misreading your post, but I don’t see where you are making the value of “myUserID” externally visible. What does your “logUserIn” method look like? Are you synthesizing the getter/setter for “myUserID?”

Has it got to do with the hosting of the web service?

I used ur code pretty much exactly in my project,just with some minor modifications, i just want to know if i have to put a copyright notice u might have made before i submit the application?

good tutorial…thanks!

Great entry point into WS communication from iPhone! Works for WSDLs without any problems! Thanks a lot!

Thank you for the great tutorial. I have one question though. In the example given you pass a string value ‘nameInput.Text’ to the NSString. However, how would one go about adding a boolean value to the NSString? I need to tell the Web Service whether I want the result back compressed or not. And I would like to set it to false.

Thank’s so much!

Hi All,
This is a fantastic article. Thank you so much!

I have a question: How would someone handle self signed or invalid SSL certificates in the context of this code?

I’ve seen some people use;
@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
return YES; // Or whatever logic
}
@end

which is dangerous. I was wondering if there’s a way to pop up a accept or decline before posting? Right now, this code simply refuses the connection.

Thanks!

thanks !!!!! I hope someone can tell me that trick. thanks for help

from this post i got 20% of m solution thanks for share

Wowo !!
This i phone application is very informative and useful.

[NSString stringWithFormat:
@""
""
""
""
"MortgageGetLoanOfficerInfo"
"919703661366"
""
""
""
];
NSLog(@”%@”,soapMsg);
NSURL *url = [NSURL URLWithString:@"http://10.10.8.7/MobileGenericWebservice/GenericWebService.asmx"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]];
[req addValue:@"text/xml; charset=utf-8"
forHTTPHeaderField:@"Content-Type"];
[req addValue:@"Mortgage/GenericAndroidMethod"forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength
forHTTPHeaderField:@"Content-Length"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn) {
NSLog(@”connected %@”,conn);
webData = [[NSMutableData data] retain];
}
}

-(void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *) response {

length:[webData length]
encoding:NSUTF8StringEncoding];
//—shows the XML—

This is a good article. But do you have an example of calling a WCF server that requires username and password authentication. I am in the process of a project and I need to be able to call a WCF service (that requres username/password ) from the iPhone/iPad. The result coming back will be an array of objects.

Excellent tips and a great article. Nicely done!
wow that’s great

Your post have good information photo are also inspire to me on this website…….
thanks for sharing great information…

Thanks for the great tutorial

Just wanted to say thanks so much for making this tutorial. I’ve tried various code-generation utilities, and scoured the web for information on iPhone and SOAP. Way too many hours. With your tutorial, I was actually able to get it working. Much appreciated!

This was a challenge for me too. I was able to tackle it by implementing
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

I’d have to give blessing with you on this. Which is not something I typically do! I love reading a post that will make people think. Also, thanks for allowing me to comment!

Hi,

I am trying to retrieve a file using soap envelope as mentioned but the problem is that when i parse the xml and find on the element to read the file , the data is encoded as UTF-8 and i want to get it as a binary inorder to be able to save the file ..

My problem is that i cann’t get the binary data from the xml …

HI
Im new in iphone world. so plz can u give me idea, how to receive data for parsing? Actually i m sending data by NSURLConeection , but i have no idea how can receive data for parsing?

Thanxxxxxxxxx

The video is not available!
http://icodeblog.com/wp-content/uploads/2008/11/SOAPTutorial.mov

Is it possible to let me where can I find it!

if its string we can handle it but if the call to xml web service returns byte[] then how will you parse it.
Show me sample code for it. I need to display the byte[] in iphone

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict

can someone recommend a book on web services. I am new to web services but I am NOT new to iphone development.
Thanks

It’s not scripted. It isn’t a monologue. Mobile advertising and apps
have added to the new, online conversation you have to start with

just put your wsdl and generate…

This is helpful to the extent of me understanding what your doing and being able to do it with what I’m wanting to do.
I’m getting quite confused as of where I’m needing to put what I need where?
If you can help put this example into the blondest of blonde terms would be much appreciated. 

oh nevermind I got it!

Have you deliberately put the code in images so that no-one can copy and paste it?

the sample code link is available.. just after the post ends. Pretty small link though, could easily be missed.

i will try

How do I consume web service in objective -C using secured protocol like HTTPS?

great tutorial about soap services! finally done what i needed to and without pain. although it took a lot to find this page !

This is a great tutorial , but I am always getting this : 

2011-10-18 20:18:30.134 Hello_SOAP[2833:207] ERROR with theConenction

hello,i would like to run this code but i didnt receive any output just it say buil successfuly and when i press button nothing appear.. how can i fix it pls helpp??
