ios - 如何在触摸时删除 uiviewanimation 块

Question

我正在从 viewDidLoad 调用一个函数 [self moveFishLeft] 并且对象正在正确设置动画，但是当我尝试删除 touchesBeganWithEvent 上的动画时，动画仍然存在。那么如何删除屏幕触摸上的所有左右功能动画。

- (void)moveFishLeft {

    [UIView animateWithDuration:6.0f   
                          delay:0.0f

                     animations:^{  
                         [optionView1 setFrame:CGRectMake(0, 480, 130, 110)];  
                         [optionView2 setFrame:CGRectMake(0, 600, 130, 110)];   
                         [optionView3 setFrame:CGRectMake(130, 530, 130, 110)];

}

Answer 1

请参考以下代码：- [self.view.layer removeAllAnimations]; 使用它可能很有用。

Answer 2

您忘记将所有“removeAllAnimations”包装在 CATransaction 中：

（需要 QuartzCore 导入）

[CATransaction begin];
[optionView1.layer removeAllAnimations];
[optionView2.layer removeAllAnimations];
[optionView3.layer removeAllAnimations];
[optionView4.layer removeAllAnimations];
[optionView5.layer removeAllAnimations];
[optionView6.layer removeAllAnimations];
[CATransaction commit];
