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

Swift 4:

let subviewButtons = self.view.subviews.filter({$0.isKind(of: UIButton.self)})

for button in subviewButtons {
    //do something        
}
