ios - 如何停止 UIViewAnimationOptionRepeat UIView 动画？

Question

我在 UIView 子类中有以下代码:

[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，我将以下消息发送到 View 本身:

[[self layer] removeAllAnimations];

但它什么也没做...我怎样才能停止动画？

Answer 1

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。

顺便说一句。非常感谢 Malloc!
