ios - titulos - Pulsación de botón y gesto de pulsación larga.

tags h2

Question

Estoy teniendo un pequeño problema con los gestos.

Estoy tratando de usar el toque y la pulsación prolongada en el mismo botón, así que he usado

@IBAction func xxx (sender: UITapGestureRecognizer)

y

@IBAction func xxx (sender: UILongPressGestureRecognizer)

pero mi botón parece reaccionar a ambas funciones cuando toco. ¿Qué podría estar mal?

func long(longpress: UIGestureRecognizer){
if(longpress.state == UIGestureRecognizerState.Ended){
homeScoreBool = !homeScoreBool
}else if(longpress.state == UIGestureRecognizerState.Began){
print("began")
}
}

Es difícil decir qué no funciona con su código, con las dos únicas filas que ha proporcionado, pero le recomendaría que lo haga de esta manera:

Crear una salida a su botón en su lugar

@IBOutlet weak var myBtn: UIButton!

Y en tu viewDidLoad() agrega los gestos a los botones

let tapGesture = UITapGestureRecognizer(target: self, action: "normalTap")
let longGesture = UILongPressGestureRecognizer(target: self, action: "longTap:")
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)

Y luego crear las acciones para manejar los grifos.

func normalTap(){
print("Normal tap")
}
func longTap(sender : UIGestureRecognizer){
print("Long tap")
if sender.state == .Ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .Began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}

Versión Swift 3.0:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.normalTap))
let longGesture = UILongPressGestureRecognizer(target: self, action: Selector(("longTap:")))
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
myBtn.addGestureRecognizer(longGesture)
func normalTap(){
print("Normal tap")
}
func longTap(sender : UIGestureRecognizer){
print("Long tap")
if sender.state == .ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}

Sintaxis actualizada para Swift 4.x:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(normalTap(_:)))
tapGesture.numberOfTapsRequired = 1
myBtn.addGestureRecognizer(tapGesture)
let longGesture = UILongPressGestureRecognizer(target: self, action: #selector(longTap(_:)))
myBtn.addGestureRecognizer(longGesture)
@objc func normalTap(_ sender: UIGestureRecognizer){
print("Normal tap")
}
@objc func longTap(_ sender: UIGestureRecognizer){
print("Long tap")
if sender.state == .ended {
print("UIGestureRecognizerStateEnded")
//Do Whatever You want on End of Gesture
}
else if sender.state == .began {
print("UIGestureRecognizerStateBegan.")
//Do Whatever You want on Began of Gesture
}
}
