iphone - 推送通知徽章不来

Question

我正在将此代码用于苹果推送通知，推送通知即将到来，但它们没有任何徽章，任何建议此代码有什么问题，我没有收到徽章。我已经检查了设置选项卡，那里有徽章。

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

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

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken1 { 

    NSString *str = [NSString 
                     stringWithFormat:@"%@",deviceToken1];
    NSLog(@"%@",str);

    self.deviceToken = [NSString stringWithFormat:@"%@",str];
    NSLog(@"dev --- %@",self.deviceToken);
    self.deviceToken = [self.deviceToken stringByReplacingOccurrencesOfString:@"<" withString:@""];
    self.deviceToken = [self.deviceToken stringByReplacingOccurrencesOfString:@" " withString:@""];
    self.deviceToken = [self.deviceToken stringByReplacingOccurrencesOfString:@">" withString:@""];
    NSLog(@"dev --- %@",self.deviceToken);


}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 

    NSString *str = [NSString stringWithFormat: @"Error: %@", err];
    NSLog(@"%@",str);    

}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"Received notification: %@", userInfo);
    //[self addMessageFromRemoteNotification:userInfo];

    NSString* alertValue = [[userInfo valueForKey:@"aps"] valueForKey:@"badge"];
    NSLog(@"my message-- %@",alertValue);
    int badgeValue= [alertValue intValue];

    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeValue];


}

我的服务器端编码存在问题，因为我刚刚发现徽章值必须隐式设置为整数才能获得所需的结果。

因为我在徽章值中得到空值。
