ios - 如何实现方法: - (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag

Question

我有两个代码块(也在 another topic 中描述)

- (void)AnimateImage:(NSString*)direction{
    self.CurrentAnimal.image = [images objectAtIndex:image_nr];
    CATransition *animation = [CATransition animation];
    [animation setDuration:1.0];
    [animation setType:kCATransitionPush];
    if([direction isEqualToString:@"left"]){
        [animation setSubtype:kCATransitionFromLeft];
    }
    else {
        [animation setSubtype:kCATransitionFromRight];
    }
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]];
    [[self.CurrentAnimal layer] addAnimation:animation forKey:nil];
}

和

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag
{
    //do what you need to do when animation ends...
}

我知道我需要“设置委托(delegate)属性并实现方法”来捕获 animationDidStop 事件，但我无法让它工作。

问题 - 如何设置 .h 和 .m 文件，以便在 CATransition 动画停止时使用此方法执行代码？

Answer 1

设置委托(delegate):

CATransition *animation = [CATransition animation];
....
[animation setDelegate:self];
[animation setDuration:1.0];
[animation setType:kCATransitionPush];
