Referencing a UIButton by tag value

Question

I am aware that a pushed button can be updated by reference to sender. However I want to access a button from the program body by reference to its tag and then update its label,if that is possible. Suggestions on how to do this (in Swift) would be appreciated.

Answer 1

To get a button inside a view using its tag, you can use the UIView.viewWithTag function.

if let button = self.view.viewWithTag(tag) as? UIButton
{
     button.setTitle("newTitle", forState: UIControlState.Normal)
}
