I found the only way to get this to work per view is to wrap your rootView in a HostingController like:
class HostingController<ContentView>: UIHostingController<ContentView> where ContentView : View {
init(view: ContentView) {
super.init(rootView: view)
NotificationCenter.default.addObserver(forName: .onDarkStatusBar, object: nil, queue: .main) { _ in
self.statusBarEnterDarkBackground()
}
NotificationCenter.default.addObserver(forName: .onLightStatusBar, object: nil, queue: .main) { _ in
self.statusBarEnterLightBackground()
}
NotificationCenter.default.addObserver(forName: .onShowStatusBar, object: nil, queue: .main) { _ in
self.statusBarShow()
}
NotificationCenter.default.addObserver(forName: .onHideStatusBar, object: nil, queue: .main) { _ in
self.statusBarHide()
}
}
@objc required dynamic init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
private var isDarkContentBackground = false
private var isStatusBarHiden = false
func statusBarEnterDarkBackground() {
isDarkContentBackground = false
setNeedsStatusBarAppearanceUpdate()
}
func statusBarEnterLightBackground() {
isDarkContentBackground = true
setNeedsStatusBarAppearanceUpdate()
}
func statusBarHide() {
isStatusBarHiden = true
setNeedsStatusBarAppearanceUpdate()
}
func statusBarShow() {
isStatusBarHiden = false
setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
if isDarkContentBackground {
return .lightContent
}
else
{
return .darkContent
}
}
override var prefersStatusBarHidden: Bool {
return isStatusBarHiden
}
}
Use as
let window = UIWindow(windowScene: windowScene)
window.rootViewController = HostingController(view: contentView)
Then send out a notification from onDissapear and onAppear.
extension Notification.Name {
static let onDarkStatusBar = Notification.Name("onDarkStatusBar")
static let onLightStatusBar = Notification.Name("onLightStatusBar")
static let onHideStatusBar = Notification.Name("onHideStatusBar")
static let onShowStatusBar = Notification.Name("onShowStatusBar")
}
Using
.onAppear {
NotificationCenter.default.post(name: Notification.Name.onHideStatusBar, object: nil)
}
.onDisappear {
NotificationCenter.default.post(name: Notification.Name.onShowStatusBar, object: nil)
}
