Very easy to use and set up.</li> </ol> <p>Code for option 1:</p> <pre><code>NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; NSOperationQueue *queue = [[NSOperationQueue alloc] init]; [NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { if (error) { //NSLog(@"Error,%@", [error localizedDescription]); } else { //NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]); } }]; </code></pre> <p>Code for option 2:</p> <p>You might want to download the library & include it in your project first. Then do the following. You can follow the post on setting up <a href="https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking" rel="nofollow noreferrer">here</a></p> <pre><code>NSURL *url = [NSURL URLWithString:@"http://httpbin.org/ip"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { NSLog(@"IP Address: %@", [JSON valueForKeyPath:@"origin"]); } failure:nil]; [operation start]; </code></pre>
