How to loop through all UIButtons in my Swift view?

Question

How would I loop through all UIButtons in my view in Swift? I would want to set all the titles to \"\", but my for-loop in Swift is giving an error.

Answer 1

If you have UIView's within self.view then you need to loop through the subviews while searching for UIButton. Using the accepted answer, I made this little function to do so:

Swift 4 + :

func findButton(`in` view: UIView){
    for view in view.subviews as [UIView] {
        if let button = view as? UIButton {
            // Do something with 'button'
        }else{
            // Loop through subview looking for buttons
            findButton(in: view)
        }
    }
}

Usage:

override func viewDidLoad() {
    findButton(in: self.view)
}

Hope this helps!
