Swift - determine which button was pressed with switch

Question

I have 4 buttons that call one function. Depending on which button was pressed i need to hide button inside of function that called after pressing.I dont know which button w

Answer 1

Rather then using a switch statement you can just use the sender directly.

Note that you need to specify that the sender is a UIButton (therefore this will only work if the function is only called from a button).

@IBAction func submitButton(sender: UIButton) {

    /* extra code here */

    sender.enabled = false

}

This reduces the code and also allows you to add extra buttons without code changes.
