Can't change UINavigationBar prompt color

Question

I am unable to change the prompt color on my navigation bar. I\'ve tried the code below in viewDidLoad, but nothing happens.

self.navigationCont

I suggest using a custom UINavigationBar subclass and overriding layoutSubviews:

- (void)layoutSubviews {
    [super layoutSubviews];

    if (self.topItem.prompt) {
        UILabel *promptLabel = [[self recursiveSubviewsOfKind:UILabel.class] selectFirstObjectUsingBlock:^BOOL(UILabel *label) {
            return [label.text isEqualToString:self.topItem.prompt];
        }];
        promptLabel.textColor = self.tintColor;
    }
}

Basically I'm enumerating all UILabels in the subview hierarchy and check if their text matches the prompt text. Then we set the textColor to the tintColor (feel free to use a custom color). That way, we don't have to hardcode the private _UINavigationBarModernPromptView class as the prompt label's superview. So the code is be a bit more future-proof.

Converting the code to Swift and implementing the helper methods recursiveSubviewsOfKind: and selectFirstObjectUsingBlock: are left as an exercise to the reader
