In 

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

method I am doing some actions and in 

- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

method I'm doing some other action.

If I'm tapping 3 times the touchesBegan will call 3 times. What I want is if the user continuously taps only the last touch action should perform. Is it possible or not?

您可以尝试UITapGestureRecognizer改为，并在第一次点击后禁用它。

否则，您可以使用in和inperformSelector:withObject:afterDelay:的短暂延迟。touchesEnded:withEvent:cancelPreviousPerformRequestsWithTarget:selector:object:touchesBegan:withEvent:

那有意义吗？
