無法停止以下KeyFrameAnimation：

運行下面的動畫。試着發送[upwardView.layer removeAllAnimations]; With IBActionbutton。如果任何人都可以爲另一個noob打開一些光。無法停止以下KeyFrameAnimation：

UIView* upwardView=[[UIView alloc]init]; 
[upwardView setFrame:CGRectMake(10, 175, 86, 140)]; 
[self.view addSubview:upwardView]; 
[self.stageView addSubview:upwardView]; 

NSArray *animationImages=[NSArray arrayWithObjects: 

          [UIImage imageNamed:@"win_1.png"], 
          [UIImage imageNamed:@"win_2.png"], 
          [UIImage imageNamed:@"win_3.png"], 
          [UIImage imageNamed:@"win_4.png"], 
          [UIImage imageNamed:@"win_5.png"], 
          [UIImage imageNamed:@"win_6.png"], 
          [UIImage imageNamed:@"win_7.png"], 
          [UIImage imageNamed:@"win_8.png"], 
          [UIImage imageNamed:@"win_9.png"], 
          [UIImage imageNamed:@"win_10.png"], 
          [UIImage imageNamed:@"win_11.png"], 
          [UIImage imageNamed:@"win_12.png"], 
          [UIImage imageNamed:@"win_13.png"], 
          [UIImage imageNamed:@"win_14.png"], 
          [UIImage imageNamed:@"win_15.png"],nil]; 

CAKeyframeAnimation *animationSequence = [CAKeyframeAnimation animationWithKeyPath: @"contents"]; 
animationSequence.calculationMode = kCAAnimationLinear; 
animationSequence.autoreverses = NO; 
animationSequence.duration = 0.90; 
animationSequence.repeatCount = HUGE_VALF; 
animationSequence.beginTime = 0; 



NSMutableArray *animationSequenceArray = [[NSMutableArray alloc] init]; 
for (UIImage *image in animationImages) 
{ 
    [animationSequenceArray addObject:(id)image.CGImage]; 
} 
CALayer *layer = [upwardView layer]; 
animationSequence.values = animationSequenceArray; 
[layer addAnimation:animationSequence forKey:@"contents"];

爲什麼要將upwardView添加到self.view和self.stageView？刪除該內容

[self.stageView addSubview:upwardView];

line。它應該完美地工作。

嘿Arun代碼完全按照您的指示運行，只要它在動畫方法中即可。我不知道如何在IBAction中調用這個。對於noobness抱歉。 – Subsonique
