Multiple connections in Swift - how to figure out which button was pressed?

Question

I have four buttons all with the same connection to a single function within the code, and I can't figure out how to determine which button sent the request. ~_~

Answer 1

You can simply check the title of the button pressed for instance with button.currentTitle

If all buttons have the same one, you can check its restoration id

Answer 2

As a 3rd alternative (now) you can use the tag property and simply number the single buttons.

func buttonPressed(sender: AnyObject) -> () {
    if let button = sender as? UIButton {
        switch (button.tag){
        case 1:
        //code
        case 2:
        //code
        case 3:
        //code
        case 4:
        //code
        }
    }
}

Answer 3

func buttonPressed(sender: AnyObject) -> () {
    if let button = sender as? UIButton {
        println("\(button.currentTitle)")
    } else {
        println("sender is not a UIButton!")
    }
}

Answer 4

You could set each UIButton's tag to "1" "2" "3" "4"

func buttonPressed(sender: AnyObject) {
    if sender.tag == 1 {
        //Code for button1
    } else if sender.tag == 2 {
        //Code for button2
    } else if sender.tag == 3 {
        //Code for button3
    } else if sender.tag == 4 {
        //Code for button1
    }
}
