核心动画animationDidStop与链接动画

我在自定义UIView，anim1和anim2中有两个动画。 Anim1将它的委托设置为self，并且在我的类中有一个animationDidStop方法触发Anim2。如果我想在Anim2完成时发生其他事情，我该怎么做？我可以使用不同的名称指定委托方法吗？核心动画animationDidStop与链接动画

UPDATE

我声明两个动画作为IVARS：

CABasicAnimation *topFlip; 
CABasicAnimation *bottomFlip;

我建立每个动画并设置delgate自例如

- (CABasicAnimation *)bottomCharFlap: (CALayer *)charLayer 
{ 


bottomFlip = [CABasicAnimation animationWithKeyPath:@"transform"]; 

charLayer.transform = CATransform3DMakeRotation(DegreesToRadians(0), 1, 0, 0); //set to end pos before animation 

bottomFlip.toValue  = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(DegreesToRadians(-360), 1, 0, 0)]; 
bottomFlip.fromValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(DegreesToRadians(-270), 1, 0, 0)]; 
bottomFlip.autoreverses = NO; 
bottomFlip.duration  = 0.5f; 
bottomFlip.repeatCount = 1; 
bottomFlip.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseOut]; 
bottomFlip.delegate = self; 
bottomFlip.removedOnCompletion = FALSE; 



return bottomFlip; 
}

然后我试图找到bottomFlip在animationdidStop：

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag { 
if (theAnimation == bottomFlip) { 
    NSLog(@"Bottom Animation is: %@", bottomFlip); 
} 
NSLog(@"Animation %@ stopped",theAnimation); 


[bottomHalfCharLayerFront addAnimation:[self bottomCharFlap:bottomHalfCharLayerFront] forKey:@"bottomCharAnim"]; 
bottomHalfCharLayerFront.hidden = NO; 
topHalfCharLayerFront.hidden = YES; 


//insert the next one??? 
}

“动画停止”记录，但没有别的也就是说，它似乎并没有认识到bottomFlip伊娃

这似乎工作：

- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag { 
//NSLog(@"First Animation stopped"); 

if (anim ==[topHalfCharLayerFront animationForKey:@"topCharAnim"]) { 
    NSLog(@"Top Animation is: %@", anim); 
    topHalfCharLayerFront.hidden = YES; 
    [bottomHalfCharLayerFront addAnimation:[self bottomCharFlap:bottomHalfCharLayerFront] forKey:@"bottomCharAnim"]; 
    bottomHalfCharLayerFront.hidden = NO; 
} 

else if ((anim ==[bottomHalfCharLayerFront animationForKey:@"bottomCharAnim"])) { 

    NSLog(@"Bottom Animation is: %@", anim); 

}

就不放将你的动画引用为ivars，并将它们的内存地址与交给animationDidStop的内存地址进行比较：

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag 
{ 
    if (theAnimation == anim1) 
    { 
    // Spin off anim2 
    } 
    else 
    { 
    // anim2 stopped. Make something else occur 
    } 
}

谢谢！这可以通过addAnimation forKey的'forKey'来完成吗？或者，这只适用于删除动画？ – codecowboy 2010-08-31 03:23:37

我已经在上面添加了一些代码。如果我在添加动画后记录动画的内存地址，然后将其记录在animationDidStop中，则内存地址不匹配。我认为这就是为什么你的建议没有奏效。如果（theAnimation == anim1）从未成功。 – codecowboy 2010-08-31 06:04:54
