didRegisterForRemoteNotificationsWithDeviceToken未在ios8中调用,但是已经注册了…

我跟着 this thread,但方法didRegisterForRemoteNotificationsWithDeviCEToken仍然没有被调用：

文件说：

didRegisterUser看起来很好,但没有注册通知.

这是AppDelegate中的代码(应用程序版本是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
}

我也有背景模式 – > info.plist中的远程通知.

- (void)application:(UIApplication *)application didRegisterUserNotificationSetTings:(UIUserNotificationSetTings *)notificationSetTings {
    if (notificationSetTings.types != UIUserNotificationTypeNonE) {
        NSLog(@"didRegisterUser");
        [application registerForRemoteNotifications];
    }
}
