I want to pass an Int to a function so I can change the background color of the right UIButton
Example:
@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!
changeBackground(1);
func changeBackground(number:Int){
button(number).backgroundColor = UIColor.redColor()
}
You can add a tag for each Button in interface Builder, or create an Array containing your Buttons. Then you pass the index of the button you want to update to your function.
Edit:
Instead of passing in a number it probably would be better to pass in the button itself. This way you can re-use the method more easily.
I would have done it differently. Create a global variable e.g.:
var buttonColor: Int = 0
and do a switch statement or if-else so that when:
switch(buttonColor):
case 1:
//set color here
case 2:
//set color here
also this can help further to know which button to be changed since UI components have storyboard ID:
