iOS: setting Exclusive Touch to all buttons in a view

Question

My app has many buttons in a Window and I want to set Exclusive Touch all of them together. Do you have any suggestion about this? Thanks

Answer 1

If you are adding buttons pragmatically, then send a message to the button [button setExclusiveTouch:YES]; for each buttons before adding to its super view. Else if you are using xib, you have to send the same message to the button in viewDidLoad or in loadView.

Answer 2

Here is some code in swift that will set exclusive touch to all buttons in your viewcontroller's view

for button in self.view.subviews {
    if(button.isKindOfClass(UIButton)){
        (button as! UIButton).exclusiveTouch = true
    }
}
