Treehouse TeacherThere are different ways to do this, and we will definitely be covering them here in the future. Until then, check out Apple's documentation about NSURLConnection, which is the default way to do asynchronous processing.
If you're familiar with Blocks (to be covered soon here), you can try the NSURLConnection method sendAsynchronousRequest:queue:completionHandler:, like this example from StackOverflow.
EDIT: Forgot to mention my favorite: search GitHub for something like "iOS asynchronous" to find some cool 3rd party libraries for this, like AFNetworking. This is an awesome networking framework that I highly recommend.
