相关疑难解决方法(0)

我正在制作一个应用程序,我想在其中实现apple推送通知服务.我按照本教程中给出的分步说明进行操作.

但仍然没有调用这些方法.我不知道造成这个问题的原因.谁能帮我？

    - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
        //NSString * token = [[NSString alloc] initWithData:deviceTokenencoding:NSUTF8StringEncoding];
        NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
        NSLog(@"Device Token:%@",str);

        //NSLog(@"Device token is called");
        //const void *devTokenBytes = [deviceToken bytes];
        //NSLog(@"Device Token");
    }

    - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
        NSString *str = [NSString stringWithFormat: @"Error: %@", err];
        NSLog(@"Error:%@",str);    
    }

我按照这个线程,但didRegisterForRemoteNotificationsWithDeviceToken仍未调用该方法:

文件说:

在调用UIApplication对象的registerForRemoteNotifications方法后,应用程序在设备注册成功完成时调用此方法

didRegisterUser看起来很好,但不是did register notif.

这是我在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 …
