I guess your question is:

How to set the text color of a UIButton?

If so, you need to have a look at the following method

- (void)setTitleColor:(UIColor * _Nullable)color forState:(UIControlState)state

Why does tintColor not work?

From the Apple docs on UIButton's property tintColor:

This property has no default effect for buttons with type UIButtonTypeCustom. For custom buttons, you must implement any behavior related to tintColor yourself.

As a newly created UIButton defaults to the UIButtonTypeCustom type, tintColor has no effect.

P.S.

You are setting self.timerButton setTintColor:[UIColor redColor]; outside the viewDidLoad method, but I guess that's just a copy/paste error here...?
