UIViewControllers have viewWillAppear, viewDidDisappear, etc. delegate methods.
I would like to create a UIView subclass that can be added to a viewController's view, and when that UIViewController apears or disappears, a delegate function is called.
I could easily do this by putting function calls in the UIViewController viewWillAppear/viewWillDisappear delegate functions, but how can I encapsulate this behavior in the UIView?
