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)
}

你需要用目标和动作初始化UITapGestureRecognizer，如下所示:

let tap = UITapGestureRecognizer(target: self, action: "handleTap:")
tap.delegate = self
myView.addGestureRecognizer(tap)

然后，你应该实现处理程序，它将在每次tap事件发生时被调用:

func handleTap(sender: UITapGestureRecognizer) {
  // handling code
}

首先，创建一个UITapGestureRecognizer对象

var tapGesture = UITapGestureRecognizer()

第二步是初始化UITapGestureReconizer。启用用户 交互，然后添加它。

override func viewDidLoad() {
        super.viewDidLoad()
    tapGesture = UITapGestureRecognizer(target: self, action: #selector(YourViewController.myviewTapped(_:)))
            infosView.isUserInteractionEnabled = true
            infosView.addGestureRecognizer(tapGesture)
view.addSubview(infosView)
}

第三，创建一个方法

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

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)

试试下面的swift代码(在Xcode 6.3.1中测试):

    import UIKit

    class KEUITapGesture150427 : UIViewController {
      var _myTap: UITapGestureRecognizer?
      var _myView: UIView?

      override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.whiteColor();

        _myTap = UITapGestureRecognizer(target: self
, action: Selector("_myHandleTap:"))
        _myTap!.numberOfTapsRequired = 1

        _myView = UIView(frame: CGRectMake(100, 200, 100, 100))
        _myView!.backgroundColor=UIColor.blueColor()
        _myView!.layer.cornerRadius = 20
        _myView!.layer.borderWidth = 1
        _myView!.addGestureRecognizer(_myTap!)
        view.addSubview(_myView!)
      }

      func _myHandleTap(sender: UITapGestureRecognizer) {
        if sender.state == .Ended {
          println("_myHandleTap(sender.state == .Ended)")
          sender.view!.backgroundColor
          = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 1.0);
        }
      }
    }

注意，你的目标可以是UIResponder的任何子类，参见(在Xcode 6.3.1中测试):

    import UIKit

    class MyTapTarget  : UIResponder {
      func _myHandleTap2(sender: UITapGestureRecognizer) {
        if sender.state == .Ended {
          println("_myHandleTap2(sender.state == .Ended)")
          sender.view!.backgroundColor
            = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 1.0);
        }
      }
    }

    class KEUITapGesture150427b : UIViewController {
      var _myTap: UITapGestureRecognizer?
      var _myView: UIView?
      var _myTapTarget: MyTapTarget?

      override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = UIColor.whiteColor();

        _myTapTarget = MyTapTarget()
        _myTap = UITapGestureRecognizer(target: _myTapTarget!
, action: Selector("_myHandleTap2:"))
        _myTap!.numberOfTapsRequired = 1

        _myView = UIView(frame: CGRectMake(100, 200, 100, 100))
        _myView!.backgroundColor=UIColor.blueColor()
        _myView!.layer.cornerRadius = 20
        _myView!.layer.borderWidth = 1
        _myView!.addGestureRecognizer(_myTap!)
        view.addSubview(_myView!)
      }
    }

而不是调用myView的UITapGestureRecognizer，你可以直接调用handleTap函数，
