ios7.1：推送通知徽章更新问题

Question

我在我当前的一个项目中设置了Push Notification。我已遵循推送通知所需的所有说明。在 [tag: ios7] 中工作正常，但在 7.1 中，当我的应用程序处于后台模式时，我的徽章更新出现问题。

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);
}

为了得到回应

-(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，当我的应用程序返回 didReceiveRemoteNotification 没有被调用时，我进行了一些搜索并输入：-

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

并设置背景模式，如：-

当我的设备与 xcode 连接并运行应用程序测试推送通知时，一切正常，但是当我拔下设备时（iOS7.1）。然后推送通知到达，但徽章没有更新。否则，该徽章会在后台更新以及调用的所有方法。但是同样的事情，我用iOS7 在我的另一台设备上测试了这个应用程序，运行良好。

我不明白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认为没有什么所以请帮助我解决这个问题。

试试：

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

Answer 2

我最近遇到了这个问题，我不得不做一些演员：

NSDictionary *apsData = [userInfo objectForKey:@"aps"];
NSInteger badgeNumber = (NSInteger)[[apsData  objectForKey: @"badge"] intValue];

[UIApplication sharedApplication].applicationIconBadgeNumber = 
            [UIApplication sharedApplication].applicationIconBadgeNumber + badgeNumber;

我是使用PHP 将数据发送到苹果服务器，所以我也在那里进行了演员：

$playload = array('aps'=>array(
                         'message'=> 'some message',
                         'badge'=> (int)$badge 
                 )
);
