我是在swift上的Xcode 6.4上完成的。见下文。

var view1: UIView!

func assignTapToView1() {          
  let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap"))
  //  tap.delegate = self
  view1.addGestureRecognizer(tap)
  self.view .addSubview(view1)

...
}

func handleTap() {
 print("tap working")
 view1.removeFromSuperview()
 // view1.alpha = 0.1
}

Swift 4的完整答案

步骤1:为视图创建一个出口

@IBOutlet weak var rightViewOutlet: UIView!

步骤2:定义一个点击手势

var tapGesture = UITapGestureRecognizer()

步骤3:创建ObjC函数(当视图被点击时调用)

@objc func rightViewTapped(_ recognizer: UIGestureRecognizer) {
    print("Right button is tapped")
}

步骤4:在viewDidLoad()中添加以下内容

let rightTap = UITapGestureRecognizer(target: self, action: #selector(ViewController.rightViewTapped(_:)))
    rightViewOutlet.addGestureRecognizer(rightTap)

内部ViewDidLoad

let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))
    self.imgMainAdView.isUserInteractionEnabled = true
    self.imgMainAdView.addGestureRecognizer(tapGestureRecognizer)

//MARK: - Image Tap Method -
@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{
    print("Tapped")
    if let url = URL(string: self.strMAinAdvLink)
    {
        UIApplication.shared.open(url, options: [:])
    }
}

打电话的目的

@IBAction func btnCall1Action(_ sender: Any)
{
    let text = self.strPhoneNumber1!
    let test = String(text.filter { !" -()".contains($0) })
    UIApplication.shared.openURL(NSURL(string: "tel://\(test)")! as URL)
}

邮件的目的

MFMailComposeViewControllerDelegate

 @IBAction func btnMailAction(_ sender: Any)
{
    let strEmail = SAFESTRING(str:  (self.dictEventDetails?.value(forKeyPath: "Email.value_text.email") as! String))

    if !MFMailComposeViewController.canSendMail()
    {
        AppDelegate.sharedInstance().showAlertAction(strTitle: "OK", strMessage: "Mail services are not available") { (success) in
        }
        return
    }
    let composeVC = MFMailComposeViewController()
    composeVC.mailComposeDelegate = self
    composeVC.setToRecipients([strEmail])
    composeVC.setSubject("")
    composeVC.setMessageBody("", isHTML: false)
    self.present(composeVC, animated: true, completion: nil)
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?)
{
    controller.dismiss(animated: true, completion: nil)
}

斯威夫特4

let tap = UITapGestureRecognizer(target: self, action: #selector(self.touchTapped(_:)))
    self.view.addGestureRecognizer(tap)

@objc func touchTapped(_ sender: UITapGestureRecognizer) {
}

注意:不要忘记在视图上启用交互:

let tap = UITapGestureRecognizer(target: self, action: #selector(handleTap))

view.addGestureRecognizer(tap)

// view.userInteractionEnabled = true

self.view.addSubview(view)

    let tap = UITapGestureRecognizer(target: self, action: Selector("handleFrontTap:"))
    frontView.addGestureRecognizer(tap)

// Make sure this is not private
func handleFrontTap(gestureRecognizer: UITapGestureRecognizer) {
    print("tap working")
}
