我想动画一个UIImageView＆amp;在动画中我想识别它上面的事件

Question

当动画UIImageView时，它不会在动画期间发送事件，但是当它完成动画时，那时它能够发送事件，我也尝试了UIButton。

Answer 1

在调用动画时，您只需要包含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
