How can I invalidate a touches moved method in Objective C?

Question

I have a touchesmoved method that moves a ball depending on the position of the user's touch. How can I stop the ball from being dragged after the user gets a "Game Over".

Example - An NSTimer will be cancelled by calling [NSTimer invalidate]. How can I do that but with a touchesmoved method?

You could disable user interaction in the view: view.userInteractionEnabled = NO;

That way the touchesMoved function would not be called, but would also disable any UI elements in that view.

Another option is to have a BOOL gameOver variable, and in your touchesMoved function check the value, if it's true, return immediately and do nothing.

Using the BOOL worked perfectly! I can't believe I didn't think of it before. Thanks. – MrBear36 Nov 16 '15 at 17:11
