Adding TapGestureRecognizer to UILabel in Swift

Question

I add UITapGestureRecognizer:tapGesture , I want the klikPlay() tag to perform its actions when I click (touch) it.

when I run the code and press / touch the label, it gives this error:

unrecognized selector sent to instance.

This is about the Player(named: label) label Player(named: label) , UITapGestureRecognizer(named:tapGesture) and the klikPlay function

What am I doing wrong?

  override func didMoveToView(view: SKView) { let background = SKSpriteNode(imageNamed: "bgStart2") background.position = CGPoint(x:0, y:0) background.anchorPoint=CGPoint(x:0,y:1.0) background.size = frame.size addChild(background) //label Play var label: UILabel = UILabel() label.frame = CGRectMake(frame.size.width/4, frame.size.height/9, frame.size.width, frame.size.height/6) label.text = "Play" label.font = UIFont(name: "Noteworthy-Bold", size:50) label.textColor = UIColor.whiteColor() label.textAlignment = NSTextAlignment.Center label.center = CGPointMake(frame.size.width/2, 4 * frame.size.height/8 ) label.hidden = false //label map var label2: UILabel = UILabel() label2.frame = CGRectMake(frame.size.width/4, frame.size.height/9, frame.size.width, frame.size.height/6) label2.text = "Map" label2.font = UIFont(name: "Noteworthy-Bold", size:50) label2.textColor = UIColor.whiteColor() label2.textAlignment = NSTextAlignment.Center label2.center = CGPointMake(frame.size.width/2, 5 * frame.size.height/8 ) label2.hidden = false //label sounds var label3: UILabel = UILabel() label3.frame = CGRectMake(frame.size.width/4, frame.size.height/9, frame.size.width, frame.size.height/6) label3.text = "Sounds" label3.font = UIFont(name: "Noteworthy-Bold", size:50) label3.textColor = UIColor.whiteColor() label3.textAlignment = NSTextAlignment.Center label3.center = CGPointMake(frame.size.width/2, 6 * frame.size.height/8 ) label3.hidden = false //label info var label4: UILabel = UILabel() label4.frame = CGRectMake(frame.size.width/4, frame.size.height/9, frame.size.width, frame.size.height/6) label4.text = "Info" label4.font = UIFont(name: "Noteworthy-Bold", size:50) label4.textColor = UIColor.whiteColor() label4.textAlignment = NSTextAlignment.Center label4.center = CGPointMake(frame.size.width/2, 7 * frame.size.height/8 ) label4.hidden = false self.view?.addSubview(label) self.view?.addSubview(label2) self.view?.addSubview(label3) self.view?.addSubview(label4) label.userInteractionEnabled = true label2.userInteractionEnabled = true label3.userInteractionEnabled = true label4.userInteractionEnabled = true //the UITapGestureRecognizer let tapGesture = UITapGestureRecognizer(target: self, action: "klikPlay:") label.addGestureRecognizer(tapGesture) view.addGestureRecognizer(tapGesture) //the functions I want to run func klikPlay(sender:UITapGestureRecognizer){ var scene:GameScene! self.runAction(SKAction.sequence([SKAction.waitForDuration(0.0), SKAction.runBlock({ // var transition:SKTransition = SKTransition.flipHorizontalWithDuration(0.5) var scene1:SKScene = GameScene(size: self.size) self.view?.presentScene(scene1) label.removeFromSuperview() label2.removeFromSuperview() label3.removeFromSuperview() label4.removeFromSuperview() background.removeFromParent() }) ] )) } } 

Answer 1

It looks like you declared klikPlay as a nested function inside didMoveToView :

 override func didMoveToView(view: SKView) { // ... let tapGesture = UITapGestureRecognizer(target: self, action: "klikPlay:") func klikPlay(sender:UITapGestureRecognizer){ // ... } } 

You need it as an instance method of your class for the gesture recognizer to find it correctly:

 class MyView { var label: UILabel! // ... override func didMoveToView(view: SKView) { label = UILabel() label.frame = CGRectMake(...) // ... let tapGesture = UITapGestureRecognizer(target: self, action: "klikPlay:") } func klikPlay(sender:UITapGestureRecognizer){ // ... } }

Based on a response from Taimur Ajmal , Updated for Swift 2.X :

 override func viewDidLoad() { super.viewDidLoad() ... labelDemo.userInteractionEnabled = true // Remember to do this let tap: UITapGestureRecognizer = UITapGestureRecognizer( target: self, action: #selector(didTapLabelDemo)) labelDemo.addGestureRecognizer(tap) tap.delegate = self // Remember to extend your class with UIGestureRecognizerDelegate ... } func didTapLabelDemo(sender: UITapGestureRecognizer) { print("you tapped label \(sender)") } 

Answer 3

Pretty direct

 let tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "labelAction:") mylabel.addGestureRecognizer(tap) tap.delegate = self // Remember to extend your class with UIGestureRecognizerDelegate // Receive action func labelAction(gr:UITapGestureRecognizer) { let searchlbl:UILabel = (gr.view as! UILabel) // Type cast it with the class for which you have added gesture print(searchlbl.text) }
