Get various coordinates for touches in swift

Im trying to get the coordinates of various points when touching in a UIView for swift 4. I've seen the other post regarding a similar problem, but that code only allows the first touch to be registered. I would appreciate some help. Thanks.

Solution

  • This code will give you coordinates for every time you touch the screen. You can test it by print it out or put it straight in to a label.

    @IBOutlet weak var imageView: UIImageView!
var coordinates = CGPoint.zero

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        if let touch = touches.first{
        coordinates = touch.location(in: imageView)
        print(coordinates)
        textLabel.text = "\(coordinates)"
    }
}
