Change the Bar Style A user changes the navigation bar's style, or UIBarStyle , by tapping the “Style” button to the left of the main page. This button opens an action sheet where users can change the background's appearance to default, black-opaque, or black- translucent.
To add a navigation bar to your interface, the following steps are required: Set up Auto Layout rules to govern the position of the navigation bar in your interface. Create a root navigation item to supply the initial title. Configure a delegate object to handle user interactions with the navigation bar.
OC:
if (@available(iOS 15.0, *)) {
UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];
[appearance configureWithOpaqueBackground];
appearance.backgroundColor = [UIColor whiteColor];
appearance.shadowColor = [UIColor whiteColor];
appearance.shadowImage = [UIImage imageWithColor:[UIColor whiteColor]];
self.navigationController.navigationBar.standardAppearance = appearance;
self.navigationController.navigationBar.scrollEdgeAppearance = self.navigationController.navigationBar.standardAppearance;
}
Swift:
if #available(iOS 15.0, *) {
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .white
appearance.shadowColor = .white
appearance.shadowImage = UIImage.color(.white)
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = navigationController?.navigationBar.standardAppearance
}
just use this code, the background image can work in iOS 15
if (@available(iOS 13.0, *)) {
UINavigationBarAppearance *navigationBarAppearance = [UINavigationBarAppearance new];
[navigationBarAppearance configureWithOpaqueBackground];
[navigationBarAppearance setBackgroundImage:image];
self.navigationController.navigationBar.scrollEdgeAppearance = navigationBarAppearance;
self.navigationController.navigationBar.standardAppearance = navigationBarAppearance;
}
swift:
if #available(iOS 15.0, *) {
let appearance = UINavigationBarAppearance()
appearance.configureWithTransparentBackground()
appearance.backgroundImage = image
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = navigationController?.navigationBar.standardAppearance
}else{
self.navigationController?.navigationBar.setBackgroundImage(image, for: .default)
}
