Q: Push notification does not appear in notification centre when the app is in background iOS app

I have in my application notification comes both in foreground and in background but what happens it's not appearing in notification centre when the app is in background mode.
-(void)registerAppForPushNotification{
   UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert |UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil];
   [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
   [[UIApplication sharedApplication] registerForRemoteNotifications];
}

- (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)userInfo {
   NSLog(@"userInfo description %@",[userInfo description]);
}

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions
{
#if TARGET_IPHONE_SIMULATOR
   NSLog(@"Running in Simulator - no app store or giro");
#else
[self registerAppForPushNotification];
#endif
   if (launchOptions) { //launchOptions is not nil
   NSDictionary *userInfo = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
   if(application.applicationIconBadgeNumber>0)
  application.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] - 1;
   }
   return YES;
}

I have tried by removing content-available flag.No luck.Please help me at the earliest. Here is my payload: aps = { alert = { "action-loc-key" = "ex2016"; body = { description = dakdhksadh; nid = 542; status = 1; "time_stamp" = 1474055472; title = "Push body"; type = 1; }; }; badge = 2; sound = default; }; }
