How do I add long and tap gesture to these buttons? - ios

Question

I have a screen with 6 buttons. All the buttons are connected to one IBAction. They are tagged and I use a switch statement to determine which one was tapped.
How can I add a Long and Tap gesture to each button? So for example when I tap button 1 it know if its a long gesture or a tap gesture?
So if I tap the button will do something different then when I long press.
Thanks.
#IBAction func playPauseAudioButton(sender: UIButton) {
switch sender.tag {
case 1:
//Tap Gesture
//Long Gesture
//I need this for every button
print("1")
case 2:
print("2")
case 3:
print("3")
case 4:
case 5:
print("5")
case 6:
print("6")
default:
print("Default")
}
}

Do it like this
#IBAction func playPauseAudioButton(sender: AnyObject) {
let tapGesture = UITapGestureRecognizer(target: self, action: "normalTap:")
let longGesture = UILongPressGestureRecognizer(target: self, action: "longTap:")
tapGesture.numberOfTapsRequired = 1
sender.addGestureRecognizer(tapGesture)
sender.addGestureRecognizer(longGesture)
}
func normalTap(sender : UIGestureRecognizer) {
let recognizer: UIGestureRecognizer = sender
let tag: Int = recognizer.view!.tag
switch tag {
case 1:
// Do some action for button 1
print("1")
case 2:
print("2")
case 3:
print("3")
case 4:
print("4")
case 5:
print("5")
case 6:
print("6")
default:
print("Default")
}
}
func longTap(sender : UIGestureRecognizer) {
let recognizer: UIGestureRecognizer = sender
let tag: Int = recognizer.view!.tag
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
}
switch tag {
case 1:
// Do some action for button 1
print("1")
case 2:
print("2")
case 3:
print("3")
case 4:
print("4")
case 5:
print("5")
case 6:
print("6")
default:
print("Default")
}
}

Define two IBActions and set one Gesture Recognizer to each of them. This way you can perform two different actions for each gesture.
You can set each Gesture Recognizer to different IBActions in the interface builder.
#IBAction func tapped(sender: UITapGestureRecognizer)
{
println("tapped")
//Your animation code.
}
#IBAction func longPressed(sender: UILongPressGestureRecognizer)
{
println("longpressed")
//Different code
}
Through code without interface builder
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: "tapped:")
self.view.addGestureRecognizer(tapGestureRecognizer)
let longPressRecognizer = UILongPressGestureRecognizer(target: self, action: "longPressed:")
self.view.addGestureRecognizer(longPressRecognizer)
func tapped(sender: UITapGestureRecognizer)
{
println("tapped")
}
func longPressed(sender: UILongPressGestureRecognizer)
{
println("longpressed")
}
Hope this helps you.
