title: asynchronous UIImageView in custom UITableViewCell
body: <p>I would like to know how people implement an asynchronous UIImageView loading, if you have it inside a custom UITableViewCell, I've seen quite some examples using GCD, subclassing UIImageView.. all of them must involves NSURLRequest and NSURLConnection. So how do people do this in a subclass of UITableViewCell that has an UIImageView in it?</p>
