Is there a way to setTitle on a UIButton that updates all UIControlStates at once?

I have a UIButton, and I'd like to update its title, but I'd rather not have to always do it for each and every state like the following:

[myButton setTitle:@"Play" forState:UIControlStateNormal];
[myButton setTitle:@"Play" forState:UIControlStateHighlighted];
[myButton setTitle:@"Play" forState:UIControlStateSelected];

Is there a better way?

It's just

yourButton.setTitle("Click me", for: .normal)

The answer:

button.setTitle("All", for: .normal)

or

button.setTitle("All", for: [])

is not correct in general, because it works only if the title for some state is not already set. For example:

button.setTitle("N", for: .normal)
button.setTitle("HL", for: .highlighted)
button.setTitle("All", for: .normal)

After this code button still have title "HL" for highlighted state. So to change title for all used states in general case, you have to loop through all these states:

let states: [UIControl.State] = [.normal, .highlighted, .selected, [.highlighted, .selected]]
for state in states {
  button.setTitle("All", for: state)
}

(If you use other states e.g. .disabled, you have to add they combinations to loop as well)

Note: UIControl.State is a Set of options, so setting the title with:

button.setTitle("All", for: [.selected, .highlighted])

does not set title "All" for both selected and highlighted states, instead it sets the title "All" for the combined state which is selected and highlighted at the same time.
