I am moving an imageview with UIView using the MoveMe example provided by Apple. But what I found was that when I touch the object on the screen to drag it, I notice that all my animations on the screen slow down. I was wondering how can I get the user input without slowing the animations down? I'm trying to make a joystick for a game. Do I need some sort of thread to handle the user when they drag an object around the screen? How do others handle joystick control and animation at the same time? Thanks for any help.
