Changing the text color of a navigation bar title when "prefersLargeTitles" is set to true
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
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
} } }
