在iOS 3中有什么方法可以停止动画吗?
我知道:
#import <QuartzCore/QuartzCore.h>
[view.layer removeAllAnimations];
,但仅适用于iOS 4.0
最佳答案
尝试使用以下代码:
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...
更新:根据文档,removeAllAnimations自iOS2.0起可用
removeAllAnimations
删除所有附加到接收器的动画。
- (void)removeAllAnimations
Availability
Available in iOS 2.0 and later.
