ios - Swift:关闭 ImageView

Question

我的 View Controller 中有一个 UIImageView(通过 Storyboard设置)，我只是想知道如何在触摸时关闭它(它是一个“点击开始”图像)。

Answer 1

class ViewController: UIViewController {

    @IBOutlet weak var imageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Enable user interaction with image
        self.imageView.userInteractionEnabled = true

        // Create a UITapGestureRecognizer
        let gestureRecogniser = UITapGestureRecognizer(target: self, action: Selector("dismissImageView:"))

        // Add the UITapGestureRecognizer to the image view
        self.imageView.addGestureRecognizer(gestureRecogniser)
    }

    func dismissImageView(gestureRecognizer: UITapGestureRecognizer) {
        // Remove the image view
        self.imageView.removeFromSuperview()
    }
}
