iphone - cocoa setAnimationDidStopSelector

目前我有这个代码可以正常工作

[UIView setAnimationDidStopSelector:@selector(animationDone:finished:context:)];

- (void)animationDone:(NSString *)animationID finished:(BOOL)finished context:(void *)context {
// do stuff here
}

记录animationID的值使我为空。

如何将值传递给@selector？

我试过

[UIView setAnimationDidStopSelector:@selector(animationDone:@"animation1"finished:context:)];

那给我一个错误。

谢谢，

最佳答案

传递给选择器的字符串是您在此方法调用中使用的字符串:

[UIView beginAnimations:@"your_animation_name_here" context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationFinished:finished:context:)];
// whatever changes here
[UIView commitAnimations];

之后，您可以执行以下操作:

- (void)animationFinished:(NSString *)animationID finished:(BOOL)finished context:(void *)context
{
    if ([animationID isEqualToString:@"your_animation_name_here"])
    {
        // something done after the animation
    }
}
