iOS 8에서 푸시 알림 동의 받기

iOS 7->8 로 넘어오면서 푸시알림 동의 받는 코드가 바뀌었다.

개발 중인 앱은 최소 iOS 버전이 iOS 8버전 이상이지만 혹시나 구버전을 지원해야 하는 경우도 있기 때문에 함께 기록 해 본다.

  
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        NSLog(@"Requesting permission for push notifications...iOS 8"); // iOS 8
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:
                                                UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound categories:nil];
        [UIApplication.sharedApplication registerUserNotificationSettings:settings];
    } else {
        NSLog(@"Registering device for push notifications...iOS 7 and earlier"); // iOS 7 and earlier
        [UIApplication.sharedApplication registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeSound];
    }
}

그리고 아래는 디바이스가 APN 서버에 정상적으로 등록 되었는지 로그를 찍어서 확인 할 수 있는 코드

- (void)application:(UIApplication *)application
didRegisterUserNotificationSettings:(UIUserNotificationSettings *)settings
{
    NSLog(@"Registering device for push notifications...iOS 8"); // iOS 8
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)token
{
    NSLog(@"Registration successful, bundle identifier: %@, mode: %@, device token: %@",
          [NSBundle.mainBundle bundleIdentifier], [self modeString], token);
}

- (void)application:(UIApplication *)application
didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"Failed to register: %@", error);
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier
forRemoteNotification:(NSDictionary *)notification completionHandler:(void(^)())completionHandler
{
    NSLog(@"Received push notification: %@, identifier: %@", notification, identifier); // iOS 8
    completionHandler();
}

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)notification
{
    NSLog(@"Received push notification: %@", notification); // iOS 7 and earlier
}

- (NSString *)modeString
{
#if DEBUG
    return @"Development (sandbox)";
#else
    return @"Production";
#endif
}
