iPhone how to cancel stop performSelector
In my iPhone app, i'm using the following function to do something after some delay
- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay;
Is there any way to cancel this performSelector and stop doing some thing after the delay?
Solution 1:
[NSObject cancelPreviousPerformRequestsWithTarget:yourTarget selector:aSelector object: anArgument];
Solution 2:
I thought it might be useful for people to see some actual code, so here are two that I use to stop sounds and swiping when I go to another screen.
- (void)handleSwipeNext {
[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSwipeNext) object:nil];
[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(playPromptAndTarget) object:nil];
// do some swipe handling stuff
}
