【问题描述】：

我正在将此编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，并且徽章在那里。

- (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];

【问题讨论】：

您是否尝试过检查badgeValue 是否设置正确？

你的服务器端代码呢？

我的服务器有问题，我发现徽章值必须隐式设置为整数。

它现在可以工作了，谢谢大家。

【参考方案1】：

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

当我在徽章值中获得空值时。

【参考方案2】：

我以前也遇到过这个问题，希望对你有帮助

"aps":"alert":"dsfdsfsdfsdfsdfdfdfsdfsdf","badge":1,"sound":"a"

确保徽章值上没有双引号
