ios - 推送通知 applicationIconBadgeNumber 未在 ios7 中更新

Question

我在应用程序委托(delegate)中使用以下代码来接收远程通知，但是当应用程序在后台运行时，它的 applicationIconBadgeNumber(以红色/白色显示在应用程序图标的左上角)没有更新。当推送通知收到并出现在屏幕的上角并带有幻灯片动画时，通知负载中的角标(Badge)计数从服务器端完美地传来。

在 didFinishLaunchingWithOptions 中，我输入了以下代码

[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

远程通知委托(delegate):

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSString *deviceTokenTrimmed = [[[[deviceToken description]
                                      stringByReplacingOccurrencesOfString:@"<"withString:@""]
                                     stringByReplacingOccurrencesOfString:@">" withString:@""]
                                    stringByReplacingOccurrencesOfString: @" " withString: @""];
    currentdeviceToken=deviceTokenTrimmed;
    [[NSUserDefaults standardUserDefaults] setValue:deviceTokenTrimmed forKey:@"pushtoken"];
    NSLog(@"Device Token didRegisterForRemoteNotificationsWithDeviceToken :  %@",deviceTokenTrimmed);

}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Device Token in FailToRegister RemoteNotifications ERROR %@",error);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"%@",userInfo);
    if (application.applicationState == UIApplicationStateActive)
    {
        /***********code to show alert********/
        if (![[[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]] isEqualToString:@""] && [[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]]!=nil) {
            NSString *MSG =[[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]];
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Message" message:MSG delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
            [alert show];
        }else{
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Message" message:@"Notification Received." delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
            [alert show];
        }
    }else{
      application.applicationIconBadgeNumber =[[[userInfo objectForKey:@"aps"] objectForKey: @"badge"]integerValue];
    }

}

提前致谢。

我发现 sol，实际上 application:didReceiveRemoteNotification 在应用程序在后台时不被调用，当应用程序在后台时它的 os 负责更新 applicationIconBadgeNumber，在我的例子中，实际问题出在有效负载上。从服务器端它被设置为字符串，但它应该是整数。我正在发布用 php 编写的有效负载正确代码。

// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'sound.caf',
'badge' => $badge_count // Should be int type
);
