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

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!

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];
