如何停止iOS中的UIView动画<4

Question

有没有办法阻止iOS 3中的动画？

我知道：

#import <QuartzCore/QuartzCore.h> 
[view.layer removeAllAnimations]; 

，但它仅适用于iOS的4.0

Answer 1

与此代码尝试：

if([view.layer repondsToSelector:@selector(removeAllAnimations)]) //Check if the CALayer responds to removeAllAnimations method for iOS4+ 
    [view.layer removeAllAnimations]; 
else 
    [view.layer addAnimation:nil forKey:@"TheKeyOfTheAnimation"]; // Change TheKeyOfTheAnimation with key you have added animation for, you can also use nil for the key... 

UPDATE：按照文档removeAllAnimations可用自iOS2.0以来 removeAllAnimations 删除所有连接到动画接收器。

- (void)removeAllAnimations
