I add a UITapGestureRecognizer:tapGesture
, I want that when I click(touch) the label, klikPlay()
will run its actions.
when I run the code and click/touch the label, it gives this error:
unrecognized selector sent to instance.
It is about the label Player(named: label)
, the UITapGestureRecognizer(named:tapGesture)
and the function klikPlay
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()
})
] ))
}
}
Pretty straight forward
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)
}
Based on answer 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)")
}
