Get global tint color from code

Question

Is there a way I can get the global tint color from my project by code? To avoid a misunderstanding I mean the global tint color, which i can set in the File Inspector.

Answer 1

Swift 4.x:

extension UIColor {
    static var tintColor: UIColor {
        get {
            return UIApplication.shared.keyWindow?.rootViewController?.view.tintColor ?? .red
        }
    }
}

Usage:

textField.textColor = .tintColor

Answer 2

Easy.

Objective C:

UIColor *tintColor = [[self view]tintColor];

Swift:

let tintColor = self.view.tintColor;

This should get the tintColor set on the app. If you change it, this property should get updated. This assumes you're inside a viewController or a subclass of one and that you haven't overridden the tintColor in some superView between this view and the window.

Update: Notice if you are attempting to get the tint color of a view controller that has not been added to the window then it will not have the custom tint color since this color is inherited from the window object. Thanx to @ManuelWa for pointing this out in the comments.

Answer 3

[UIApplication sharedApplication].keyWindow.tintColor;

Answer 4

In the app delegate you can set it by

UIColor *globalTint = [[[UIApplication sharedApplication] delegate] window].tintColor;

Answer 5

Max's answer is correct, but I found out that you have to get the navigationController's window:

self.navigationController.view.window.tintColor = [UIColor redColor];

However, note that this wouldn't work if you have set the tintColor manually from Storyboard. The value from Storyboard will be used if you have done so. I've filed a bug with Apple on this. I think this code shouldn't be ignored even if we've set the tintColor from Storyboard.

Answer 6

[UIApplication sharedApplication].delegate.window.rootViewController.view.tintColor

Seems to work.
