UIButton doing different tasks - swift

Question

How do i make a UIButton do something different every time it is pressed in swift. Ive tried making two buttons that overlap and one hides when it is clicked Didn't work though.
EDIT: nevermind i found i could do this for a mute/play button
If backgroundaudio.play
Backgroundaudio.pause
Else
Backgroundaudio.play

Answer 1

You can do it in two different ways:
Changing the target of the button:
Adding a target:
button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
Removing a target:
button.removeTarget(nil, action: nil, forControlEvents: .AllEvents)
Or have a logical statement inside your action function:
button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
func buttonAction(sender: UIButton!)
{
//your conditions go here
}

For example: To do something every other time you could write:
func oneThing() {
// Do your stuff
}
func otherThing() {
// Do other stuff
}
var shouldDoOtherThing = false
#IBAction func clicked(sender: UIButton) {
if shouldDoOtherThing {
otherThing()
} else {
oneThing()
}
shouldDoOtherThing = !shouldDoOtherThing
}
You could also just do the stuff you want to do inside the if statement like
var shouldDoOtherThing = false
#IBAction func clicked(sender: UIButton) {
if shouldDoOtherThing {
// Do other stuff
} else {
// Do your stuff
}
shouldDoOtherThing = !shouldDoOtherThing
}
Or you can use anything else that changes what code should execute (they are called Control Statements)

I just tested this out. You'll only need one button.You can do as many random things as you want
#IBAction func button_click(sender: AnyObject) {
var randomNumber = Int(arc4random_uniform(5) + 1) // generates random number 1 - 5
println(randomNumber)
switch randomNumber { // perform method depending on what random number was generated
case 1 :
funcOne() // Run this method
println("Pressed 1")
case 2:
funcTwo() // Runs this method
println("Pressed 2")
case 3:
funcThree() // Runs this method
println("Pressed 3")
case 4:
funcFour() // Runs this method
println("Pressed 4")
case 5:
funcFive() // Runs this method
println("Pressed 5")
default:
println("do nothing")
}
}
