Ios Swift——当删除UIView（动画）时，它将保持在屏幕上

我有以下Swift代码。问题是，当它被执行时，它会执行动画，但窗口仍保持在原始位置，如所附的gif I所示

UIView.animateKeyframes(withDuration: 0.5, delay: 0, options: .calculationModePaced, animations: {
    self.view.viewWithTag(123)?.frame = CGRect(x: screenWidth5/2, y: screenHeight, width: screenWidth5 * 4, height: screenHeight5 * 3 )
}, completion: .none)

self.view.viewWithTag(123)?.removeFromSuperview()

感谢您的时间和回答。

您需要将

removeFromSuperview

放入完成处理程序中

UIView.animateKeyframes(withDuration: 0.5, delay: 0, options: .calculationModePaced, animations: {
    self.view.viewWithTag(123)?.frame = CGRect(x: screenWidth5/2, y: screenHeight, width: screenWidth5 * 4, height: screenHeight5 * 3 )
}) { _ in
    self.view.viewWithTag(123)?.removeFromSuperview()
}
