如何停止iPhone中的UIView CABasicAnimation

问题描述:

我有3个使用for循环动态创建的视图。在我呼吁旋转动画下面的方法如何停止iPhone中的UIView CABasicAnimation

- (void)runRightSpinAnimationOnView:(UIView*)view duration:(CGFloat)duration rotations: (CGFloat)rotations repeat:(float)repeat; 
{ 
    CABasicAnimation* rotationAnimation; 
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; 
    rotationAnimation.fromValue = [NSNumber numberWithFloat:0]; 
    rotationAnimation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)]; 
    //rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 /* full rotation*/ * rotations * duration ]; 
    rotationAnimation.duration = duration; 
    //rotationAnimation.cumulative = YES; 
    rotationAnimation.repeatCount = repeat; 

[view.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"]; 
} 

如何停止在触摸旋转动画开始的看法?... 我尝试下面的编码在触摸开始的方法,但它没有工作

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [touches anyObject]; 
    int viewTag=[touch view].tag; 
    UIView *myView =(UIView *)[self.view viewWithTag:viewTag]; 
    [myView.layer removeAllAnimations]; 
} 

请帮我...

这可能是因为你是从其他层去除动画,而不是从你上添加了动画同一层删除动画。 (您正在使用错误的视图来移除动画,请再次检查它)。

您可以用它来从yourView删除动画:?有没有办法暂停CABasicAnimation]

[yourView.layer removeAllAnimations];
