    copied!<p>I'm a complete noob at objective-C, so this might be a very silly question to a lot of you.</p> <p>Currently, I have a view with a 'SignIn' button, which when clicked, activates a sigupUp IBAction that I have defined below. Basically, this method needs to make a JSON call and get back some data about the user.</p> <p>So, right now, my code looks something like this:</p> <pre><code>-(IBAction)signIn:(id)sender{ //run registration API call //establish connection NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.apicallhere.com/api/auth"]]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"]; [request setHTTPBody:postData]; [[NSURLConnection alloc]initWithRequest:request delegate:self]; responseData = [[NSMutableData data] retain]; } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{[responseData setLength:0];} - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{[responseData appendData:data];} - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{/*NSLog(@"%@",error);*/} -(void)connectionDidFinishLoading:(NSURLConnection *)connection{ NSString *response=[[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; ....code carries on from here. } </code></pre> <p>As you can see, the problem with my code is that even though it is initiated via the 'SignUp' method, it finishes with the 'connectionDidFinishLoading' method. I want to have all this code in a single method. Not 2 separate ones, as I want to be able to return a boolean verifying if the connection was successful or not.</p> <p>If someone could please tell me how to code up this procedure into a single method, I would really appreciate it.</p>
