NSTimer가 잘 작동하지 않습니다 .. iPhone의 애니메이션

Question

iPhone 프로그래밍에 새로운 기능 .. 내 앱에서 타이머가 제대로 작동하지 않습니다. 누구든지 나를 도와주세요. 다음은 터치하거나 스 와이프하여 몇 장의 이미지를 애니메이트하는 코드입니다.

나는 타이머를 사용하여 몇 초 동안 터치를 제한하고 싶습니다 ... 이 작업을 수행하는 또 다른 방법이 ..? (장치의 충돌 타이머 사용하지만, 충돌에 대한 해결책을 시도 simulator..im에서 잘 작동하기 전에 ..) 당신이하지 않는 것

문제가 될 수있는 NSTimer를 올바르게 보관하십시오. 에

변경을 :

touchTimer = [[NSTimer scheduledTimerWithTimeInterval:3 target:self selector:@selector(sleeping) userInfo:nil repeats:NO] retain]; 

이상적으로 당신은 속성으로 touchTimer를 선언하고 합성하지만,이 먼저 시도해야합니다. 충돌에서

-(void)sleeping{ 

    NSLog(@"....Hiiii"); 
    isAnimating = FALSE; 
    [touchTimer invalidate]; 
    [touchTimer release]; 
    touchTimer = nil; 
}
