Changing the text color of a navigation bar title when “prefersLargeTitles” is set to true

Question

I have a requirement in which I have to use a UINavigationBar with a red large title.

Currently, I have the following code:

func prepare         


        

Answer 1

The way you do this in iOS 13 has changed, you now use UINavigationBarAppearance class like this…

let appearance = UINavigationBarAppearance(idiom: .phone)
appearance.largeTitleTextAttributes = [.foregroundColor: UIColor.systemRed]
appearance.titleTextAttributes = [.foregroundColor: UIColor.systemRed]
appearance.backgroundColor = .white
navigationItem.standardAppearance = appearance
navigationItem.scrollEdgeAppearance = appearance

Not sure if it's a bug in beta 1 & 2, but here is a way to set the color. It's a bit of a "hacky" workaround, but it should work until Apple fixes this. In both the Objective-C and Swift version, this code goes in the viewDidAppear: method.

Objective-C:

dispatch_async(dispatch_get_main_queue(), ^{
    for (UIView *view in self.navigationController.navigationBar.subviews) {
        NSArray <__kindof UIView *> *subviews = view.subviews;
        if (subviews.count > 0) {
            UILabel *label = subviews[0];
            if (label.class == [UILabel class]) {
                [label setTextColor:[UIColor redColor]];
            }
        }
    }
});

Swift:

DispatchQueue.main.async {
     for view in self.navigationController?.navigationBar.subviews ?? [] {  
     let subviews = view.subviews  
     if subviews.count > 0, let label = subviews[0] as? UILabel {  
           label.textColor = UIColor.red
 } } }

There is a new UINavigationBar property "largeTitleTextAttribute" that should help with this.

largeTitleTextAttribute

Here is a sample code you can add to your view controllers viewDidLoad method

        navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.blue]

Here is a sample code and screenshot without the largeTitleTextAttributes set, but the barStyle is set to .black

        navigationController?.navigationBar.barStyle = .black

Here is a screenshot without the largeTitleTextAttributes set, but the barStyle is set to .default

        navigationController?.navigationBar.barStyle = .default

Here's the working code to use large titles and sets the text color of small and large titles to white, both on iOS11+ and on older iOS versions.

// Will apply to versions before iOS 11
navigationController?.navigationBar.titleTextAttributes = [
    NSAttributedStringKey.foregroundColor: UIColor.white
]

if #available(iOS 11.0, *) {
    navigationController?.navigationBar.prefersLargeTitles = true
    navigationController?.navigationBar.largeTitleTextAttributes = [
        NSAttributedStringKey.foregroundColor: UIColor.white
    ]
}

(There used to be a bug in Xcode, but it now appears to be fixed)

If using storyboard, just change "Large Title Text Attributes" Title Color at Navigation Bar Attribute Inspector:
