In my iPad app, I want the users to be able to resize a UIView by dragging the view from its edges. I’ll be using iOS 5 SDK, so what’s the cleanest approach to do this? Are there any alternatives to achieving this without dealing with touchesBegan, touchesMoved,… etc?
I’m guessing your UI involves some kind of handles on the sides of the view, and attaching a simple
UIPanGestureRecognizerto those handle controls makes the whole problem pretty easy.In the action method from the gesture recognizer, just get the
-translationInView:relative to the view you’re resizing, save off the original frame when the gesture recognizer’s state isUIGestureRecognizerStateBegan, and adjust the view’s frame continually while the state isUIGestureRecognizerStateChanged.
