单击按钮时隐藏/显示带动画的uiimageview

上 button 单击事件,只需为 x coordinate of origin 的 imageView

例子:

@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
}

上述代码将按以下方式工作:

1. selecting 按钮 imageView's 已移至 extreme right 屏幕的( UIScreen.main.bounds.width

2. 什么时候 de-selecting , x原点坐标 已移至 extreme left 屏幕的( 0.0 )

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*/
    })
}

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*/
    })
}
