Objectivec 在 ios8 中没有调用 didRegisterForRemoteNotificationsWithDeviceToken，但是 didRegister...Settings 是

我遵循了this thread，但仍然没有调用方法didRegisterForRemoteNotificationsWithDeviceToken:

文件上说:

调用

didRegisterUser看起来不错，但不是did register notif.

以下是我在AppDelegate中的代码(应用程序版本为8.1):

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //register notif
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                    UIUserNotificationTypeBadge |
                                                    UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
    [application registerUserNotificationSettings:settings];


    return YES;
}

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
    NSLog(@"didRegisterUser");
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"error here : %@", error);//not called
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    /*
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    currentInstallation.channels = @[ @"global" ];
    [currentInstallation saveInBackground];
     */
    NSLog(@"did register notif");//not called
}

I also have background mode -> remote notification in the info.plist.
