I try to receive remote notifications in widgets(implemented through WidgetKit), but failed.

It known that enable remote notifications should register first by calling


UIApplication.shared.registerForRemoteNotifications()

but in widget cannot calling shared, it is available in widgets

@property(class, nonatomic, readonly) UIApplication *sharedApplication NS_EXTENSION_UNAVAILABLE_IOS("Use view controller based solutions where appropriate instead.");

and if try to init a UIApplication(by UIApplication()), the app will crash for more than one UIApplication instance.

Through research and investigation， the Notification Service Extension can receive remote notifications except silent notifications or those that only play a sound or badge the app’s icon by invoking - (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent *contentToDeliver))contentHandler
