如何停止UIViewAnimationOptionRepeat UIView动画？ [英] How can I stop an UIViewAnimationOptionRepeat UIView Animation?

问题描述

我在UIView子类中有以下代码：

I have the following code inside of a UIView subclass:

[element setAlpha: 0.0f];

[UIView animateWithDuration: 0.4 delay: 0.0 options: UIViewAnimationOptionCurveEaseOut | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat animations: ^{
    [element setAlpha: 1.0f];
} completion: ^(BOOL finished){
    if (finished) 
    {
        return;
    }
}];

然后，当我想停止动画时，我将以下消息发送给View本身：

Then when I want to stop the Animation I send the following message to the View itself:

[[self layer] removeAllAnimations];

但它什么都不做......我怎么能停止动画？

But it does nothing... How can I stop the animation?

推荐答案

我使用以下代码修复：

- (void)restoreAnimations {

    [UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionBeginFromCurrentState | UIViewAnimationOptionCurveLinear animations:^{
        [element setAlpha: 1.0f];
    } completion:NULL];
}

并在ViewController中调用它。

And calling it in the ViewController.

Btw。非常感谢Malloc！
