Tutorials for using HTTP POST and GET on the iPhone in Objective-C [closed]

Question

I downloaded apple's demo for using HTTP POST and GET (Their sample app has a tabbar with different parts) and the code is so confusing!

Could anybody give me some sample code or a link to some tutorials about it? :)

Thanks!

Answer 1

This walkthrough by Matt Long is particularly good: http://www.cimgf.com/2010/02/12/accessing-the-cloud-from-cocoa-touch/

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]          initWithURL:[NSURL          URLWithString:@"http://www.cimgf.com/testpost.php"]];   [request setHTTPMethod:@"POST"]; [request setValue:@"text/xml"                forHTTPHeaderField:@"Content-type"];   NSString *xmlString = @"<data><item>Item 1</item><item>Item 2</item></data>";   [request setValue:[NSString stringWithFormat:@"%d",         [xmlString length]]          forHTTPHeaderField:@"Content-length"];   [request setHTTPBody:[xmlString          dataUsingEncoding:NSUTF8StringEncoding]];   [[NSURLConnection alloc]          initWithRequest:request                     delegate:self]; 

Answer 2

this is a simple way to use GET:

   NSURL *url = [NSURL URLWithString:@"http://www.32133.com/test?name=xx"];    NSData *data = [NSData dataWithContentsOfURL:url];    NSString *ret = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];    NSLog(@"ret=%@", ret);
