NSTimer ne fonctionne pas bien ..in Animation dans l'iPhone

Question

im nouveau à la programmation iPhone .. dans mon application, la minuterie ne fonctionne pas bien. quelqu'un peut me aider ... s'il vous plaît Voici le code pour animer quelques images WN nous touchons ou swipe..they tombons

je veux limiter les touches pendant quelques secondes avec l'utilisation de la minuterie ... est-il une autre façon de le faire ..? (avant d'utiliser son horloge se brisant sur l'appareil, mais fonctionne très bien dans la simulator..im essayer de solution pour écraser ..)

Vous ne semblez pas conservez correctement le NSTimer qui pourrait être votre problème ici.

Modifier à:

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

Idéalement, vous devriez déclarer TouchTimer comme une propriété et synthétiser, mais essayez cette première.

Changement du sommeil pour libérer la minuterie:

-(void)sleeping{ 

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