xCode 9.3, Swift 4.0

class BaseVC: UIViewController, UIGestureRecognizerDelegate { 

      @IBOutlet weak var iView: UIView!

      override func viewDidLoad() {
          super.viewDidLoad()
          let clickUITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.onSelect(_:)))
          clickUITapGestureRecognizer.delegate = self
          iView?.addGestureRecognizer(tap)
      }

      func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
          return true
      }


     @IBAction func onSelect(_ sender: Any) {

     }
}

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

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

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

对于正在寻找Swift 3解决方案的任何人

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

view.addGestureRecognizer(tap)

view.isUserInteractionEnabled = true

self.view.addSubview(view)

// function which is triggered when handleTap is called
@objc func handleTap(_ sender: UITapGestureRecognizer) {
     print("Hello World")
  }

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)

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!)
      }
    }
