核心動畫animationDidStop與鏈接動畫

我在自定義UIView，anim1和anim2中有兩個動畫。 Anim1將它的委託設置爲self，並且在我的類中有一個animationDidStop方法觸發Anim2。如果我想在Anim2完成時發生其他事情，我該怎麼做？我可以使用不同的名稱指定委託方法嗎？核心動畫animationDidStop與鏈接動畫

UPDATE

我聲明兩個動畫作爲IVARS：

CABasicAnimation *topFlip; 
CABasicAnimation *bottomFlip;

我建立每個動畫並設置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; 
}

然後我試圖找到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??? 
}

「動畫停止」記錄，但沒有別的也就是說，它似乎並沒有認識到bottomFlip伊娃

這似乎工作：

- (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); 

}

就不放將你的動畫引用爲ivars，並將它們的內存地址與交給animationDidStop的內存地址進行比較：

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

謝謝！這可以通過addAnimation forKey的'forKey'來完成嗎？或者，這隻適用於刪除動畫？ – codecowboy 2010-08-31 03:23:37

我已經在上面添加了一些代碼。如果我在添加動畫後記錄動畫的內存地址，然後將其記錄在animationDidStop中，則內存地址不匹配。我認爲這就是爲什麼你的建議沒有奏效。如果（theAnimation == anim1）從未成功。 – codecowboy 2010-08-31 06:04:54
