ios7.1：推送通知徽章更新问题

我在我当前的一个项目中设置了推送通知.我已经按照推送通知所需的所有指令.在[tag：ios7]中正常工作,但在7.1中,当我的应用程序处于后台模式时,我在徽章更新中遇到问题.

我的代码如下： –

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

}


- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    NSLog(@"Failed to get token,error: %@",error);
}


- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDevicetoken:(NSData*)devicetoken
{
    Nsstring *str = [Nsstring
                     stringWithFormat:@"%@",devicetoken];
    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);
}

并获得回应

-(void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{

    UIApplicationState state = [application applicationState];

    // If your app is running
    if (state == UIApplicationStateActive)
    {

        //You need to customize your alert by yourself for this situation. For ex,Nsstring *cancelTitle = @"ok";
      //  Nsstring *showTitle = @"Get Photos";
        Nsstring *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"];
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@""
                                                            message:message
                                                           delegate:self
                                                  cancelButtonTitle:cancelTitle
                                                  otherButtonTitles:nil];
        [alertView show];


    }
    // If your app was in in active state
    else if (state == UIApplicationStateInactive)
    {

    }

     [UIApplication sharedApplication].applicationIconBadgeNumber = [UIApplication sharedApplication].applicationIconBadgeNumber + [[[userInfo objectForKey:@"aps"] objectForKey: @"badge"] intValue];

}

第一件事是,当我的应用程序回到地面时,didReceiveRemoteNotification没有被调用,所以我做了一些搜索并放置： –

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

并将背景模式设置为： –

当我的设备连接xcode并运行应用程序测试推送通知但是当我拔掉设备(iOS7.1)时,一切正常.然后推送通知到达但徽章没有更新.否则,徽章会在后台更新,也会调用所有方法.但同样的事情我测试这个应用程序到我的另一台iOS7设备,运行良好.

我无法理解我的错误在哪里以及我在代码中做错了什么.是否有任何错误或我不认为所以请帮助我这个.

解决方法

尝试：

int badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
[UIApplication sharedApplication].applicationIconBadgeNumber = 0; // try 0 or -1
[UIApplication sharedApplication].applicationIconBadgeNumber = badge + [[[userInfo objectForKey:@"aps"] objectForKey: @"badge"] intValue];
