NSLog(#"%#",data)
Thanks in advance.
Here is an article which demonstrates how to consume .NET Web service using iOS application. You can use the techniques discussed in the article:
http://www.highoncoding.com/Articles/809_Consuming__NET_Web_Services_in_an_iOS_Application.aspx
Almost all the work I do involves .NET with iOS. Have a look here for the network class I wrote and use all the time (AFNetworking based). I prefer to use a regular aspx form instead of an asmx web-service. I do this because I don't want to expose any web-methods to snooping visitors and I use an API key check before returning anything in the aspx form. I can send you an example .NET code (written in VB.NET) if you need me to.

am using web services (JSON). from json am getting data this data loading into tableview am trying to edit this data but after edit the data how to send this updated data to server.
please any one help me?
try this will help you.. this is the post method for updating data in WS .
NSString *post =[NSString stringWithFormat:#"uid=%#&firstname=%#&lastname=%#&phone=%#&bday=%#&about_me=%#&image=%#&image_code=%#&contact_number=%#",LoginID,fname,lname,cn,bday,abtme,strimage11,c11,cn];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"YOUR LINK"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *uData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:uData encoding:NSUTF8StringEncoding];
//
NSMutableDictionary *temp = [data JSONValue];
//
NSLog(#"%#",temp);
I am assuming you have your edited data, then
Form your json. There are several libraries out there which can help you.
Know the hostname of your server.
Know which API to hit on your server.
then pass this json as POST (GET is also ok, but POST is preferred).
Process this received json on your server.
Hope this helps. Nothing much to it actually.
I am trying to post a string to a URL in iphone which will be retrieved by the server. The server side scripting is done in coldfusion. I am trying to fetch the data in coldfusion and pass on the value back to iphone. I am not familiar much with coldfusion and wanted some help in this. Below is the coding in iphone :
/** Iphone code **/
NSString *post =[[NSString alloc] initWithString:#"Hello World"];
NSURL *url=[NSURL URLWithString:#"http://www.abc.com/test.cfm"];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
/*Coldfusion code */
<html>
<head><title>Test</title></head>
<body>
<cfoutput>#form.post#</cfoutput>
</body>
</html>
Am I doing it correctly ?
You may need to specify name of form variable in data. Try below for post variable. I haven't tested it should work.
NSString *post =[[NSString alloc] initWithString:#"post=Hello%20World"];
I am new to iPhone application development and also this stackoverflow,if I made any mistakes sorry. I have some of the questions
1) Do I need to install any other external framework into my application. I am using SDK Simulator 4.2
2) I have gone through some of the material which was posted here, I found some code and I made some modification to suits my application When I am requesting for a URL it is returning me NULL.
3) My task is to send a three parameters into database.
NSString *post =[NSString stringWithFormat:#"?FirstName=%#?Surname=%#?IDNumber=%#?DOB=%#",namestring,surnamestring,cidstring,dobstring];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSLog(#"Post Length:",[postData length]);
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://www.esoft.co.za/MDS/Service1.asmx?op=InsertSuppliers"]];
[request setHTTPMethod:#"GET"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(#"response data is: %#",[responseData length] );
NSString *data = [[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"Data: %#",data);
Thanks in Advance Guys...Please provide me any sample code or material..
I think it's because you're trying to send invalid request. Just try to check and log error message to see what's wrong.
What you're trying to do is to send POST data over GET request, which is wrong anyway. I'm also not sure about those "Post" data format, but when you'll check error message you'll find what's wrong.
NSLog(#"Request failed with error: %#", [err localizedDescription]);

I am new in iphone,in my app required data from the server.
1)mysql database uploaded on the server
2)With the help of php code i fetch the data from the server
problem is that how i integrate php in my iphone please solve my problem,
give any reference.
Thanks,
I'm not sure to understand your problem, but you can't use PHP on iPhone.
If you need data from an external database, create web services to get the data in JSON, XML, or what suits you best.
Your iPhone application will connect to a specific URL, and get the data from a (PHP) script that will query the database and return the result in a specific format.
The best way in my opinion is to use JSON (see http://code.google.com/p/json-framework/).
You can make requests to your server using this code
NSError *error;
NSString *post =[NSString stringWithFormat:#"any-data=%#",
myData];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://your-server.com/your-script.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(#"Data: %#",data);
NSDictionary* parsedData = [data JSONValue];
You then can access the data using
[parsedData valueForKeyPath:#"myVar"]
Hope this hepls,
Miguel
You could look at passing arrays of objects from the server to the iPhone in the form of a plist file. Have the server generate the plist in the appropriate format on a url and then on the device:
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfURL:[NSURL URLWithString:#"http://www.example.com/myplist.php"];
NSArray *array = [NSArray arrayWithContentsOfURL:[NSURL URLWithString:#"http://www.example.com/myplist.php"];
If your unsure what the format is for plist files create one in your xcode project and use that as a template.
I would like to ask about the button and the url post method in iPhone application.
In my program, I want the user to click a button, and then a url will be called by POST method. For the url, it may need to redirect to somewhere (302 or 303) etc and final is 200.
I have complete the button and the success page, however, I don't know how to use the objective-C library. I found lots of reference of this forum, but I don't understand what the code means. Can anyone help me?
The following is a question which I believe related to the question.
Invoking a http post URL from iphone using .net web service
Thank you very much.
If you're okay with blocking the thread you're making the request on, this is just about as simple as it gets.
NSString *postBody = [NSString stringWithFormat:#"param1=%#¶m2", param1value, param2value];
NSData *postData = [postBody dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:targetURL];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
A few caveats:
This will perform a synchronous (blocking) request, so either do it on a background thread or look into using the NSURLConnection delegate methods.
POST data must be URL-encoded, so you may need to do some preprocessing of your parameter values.
Redirects will occur automatically until a 200 OK or an error is encountered.
