快速直线移动物体

[英]Move object in straight line swift

I have an image and I need to move it in a straight line for example from (x, y) to (x1, y2).我有一个图像,我需要将它沿直线移动,例如从 (x, y) 到 (x1, y2)。

And after moving how do I make the image disappear?移动后如何使图像消失?

I tried to do this but I don´t know what to do next.我试图这样做,但我不知道下一步该怎么做。

@IBOutlet weak var moveobj: UIImageView!
override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    linePath.move(to: CGPoint(x: 100, y: 100))
    linePath.addLine(to: CGPoint(x: 300, y: 300))
    moveobj.layer .addAnimation(path, forKey: "path")
}
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    // Set the image view in the starting location
    moveobj.frame = CGRect(x: 100, y: 100, width: /* some width */, height: /* some height */)

    UIView.animate(withDuration: /* some duration */, animations: {
        // Move image view to new location
        self.moveobj.frame = CGRect(x: 300, y: 300, width: self.moveobj.frame.width, height: self.moveobj.frame.height)
    }) { (finished) in
        // Animation completed; hide the image view
        self.moveobj.isHidden = true
    }
}
