ios - How do I find what to refer to a UIButton as?

Question

I want a particular UIButton to change colour once a UISwitch move from OFF to ON. What do I enter

- (IBAction) Court1ON {
//here
}

to refer to a specific UIButton in my storyboard?

Answer 1

You have several possibilities to do that:

1. assign a tag to your button in storyboard; then access the button through:

   [self.view.viewByTag:buttonTag];
   

2. create an IBOutlet @property of type UIButton and bind that to your button.
