Question

当我点击按钮时，我的图像是如何实现的，我的图像会随着动画移出屏幕，当我再次点击按钮时，会回到原位？

Answer 1

在button点击事件中，只需根据您的要求为x coordinate of origin的{{1}}设置动画即可。

示例：

imageView

以上代码的工作原理如下：

当@IBAction func onTapButton(_ sender: UIButton) { if sender.isSelected { UIView.animate(withDuration: 2.0, animations: { self.imageView.frame.origin.x = 0.0 }) } else { UIView.animate(withDuration: 2.0, animations: { self.imageView.frame.origin.x = UIScreen.main.bounds.width }) } sender.isSelected = !sender.isSelected } selecting，button imageView's移至x coordinate of origin的{{1}}时

当extreme right UIScreen.main.bounds.width，de-selecting button移至imageView's的{{1}}时

使用此代码向左移动 -

func moveToLeft()
{
    var frame = imageView.frame
    frame.origin.x = -imageView.frame.size.width //Adjust this value according to your need
    UIView.animate(withDuration: 0.3, delay: 0.0, options: .curveEaseOut, animations: {() -> Void in
        self.imageView.frame = frame
    }, completion: {(_ finished: Bool) -> Void in
        /*done*/
    })
}

使用此代码向右移动 -

func moveToRight()
{
    var frame = imageView.frame
    frame.origin.x = 0 //Adjust this value according to your need
    UIView.animate(withDuration: 0.3, delay: 0.0, options: .curveEaseOut, animations: {() -> Void in
        self.imageView.frame = frame
    }, completion: {(_ finished: Bool) -> Void in
        /*done*/
    })
}

单击按钮时隐藏/显示带动画的uiimageview
