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

This code should work:

for view in self.view.subviews as [UIView] {
    if let btn = view as? UIButton {
        btn.setTitleForAllStates("")
    }
}

You need to iterate through the subViews array.
