iphone - IOSのdidFinishLaunchingWithOptionsのエラー-Objective-Cアプリ開発

Question

'didFinishLaunchingWithOptions'関数で、最後に次の行を指定しています：-

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
    return [super application:application didFinishLaunchingWithOptions:launchOptions]; 

しかし、それは次の警告を与えています：-

'NSObject' may not respond to 'application:didFinishLaunchingWithOptions' function 

そして、それをビルドすると、アプリケーションは「UncaughtExceptionerror」で終了します

なぜこれが起こっているのか誰かが提案できますか？ありがとう

Answer 1

試す

[self application:application didFinishLaunchingWithOptions:launchOptions];

NSObjectのような基本オブジェクトはのメソッドを実装しませんdidFinishLaunchingWithOptions:launchOptions

Answer 2

didFinishLaunchingWithOptions：launchOptionsの最後にYESを返す必要があります

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
return YES;
