iphone - 我想为 UIImageView 制作动画并在动画期间我想识别它上面的事件

Question

当为 UIImageView 设置动画时，它在动画期间不会发送事件，但是当它完成动画时，它能够发送事件，我也尝试过 UIButton。

Answer 1

您只需要在调用动画时包含 UIViewAnimationOptionAllowUserInteraction 选项：

[UIView animateWithDuration:animationDuration 
                          delay:0 
                        options:(UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction)
                     <snip>];

Answer 2

    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.0];// try 0.1 also
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[yourImageView layer] addAnimation:animation forKey:@"transitionViewAnimation"];//Try   self.view insted of yourImageView if you want to animate whole view
