Swift UIView animateWithDuration完成关闭立即调用 [英] Swift UIView animateWithDuration completion closure called immediately

问题描述

我希望在指定的持续时间后调用此UIView动画的完成关闭，但是它似乎会立即触发...

I'm expecting the completion closure on this UIView animation to be called after the specified duration, however it appears to be firing immediately...

 UIView.animateWithDuration(
        Double(0.2),
        animations: {
            self.frame = CGRectMake(0, -self.bounds.height, self.bounds.width, self.bounds.height)
        },
        completion: { finished in
            if(finished) {
                self.removeFromSuperview()
            }
        }
    )

还有其他人遇到过吗？我已经读到其他人在使用中心而不是框架移动视图方面取得了更大的成功，但是我在这种方法上也遇到了同样的问题。

Has anyone else experienced this? I've read that others had more success using the center rather than the frame to move the view, however I had the same problems with this method too.

推荐答案

最后，我将动画从 hitTest（）移到了 touchesBegan（）在 UIView

I resolved this in the end by moving the animation from hitTest() and into touchesBegan() in the UIView
