我想在收到静默通知时将用户位置更新到服务器。我已启用推送通知和后台模式作为远程通知和位置。但是

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

当应用程序处于终止或未运行状态时，不会调用 my 。我正在通过将位置数据发送到 pubnub 来对此进行测试。主要问题是，当我开始编写这部分代码时，它工作得很好，但过了一段时间它就停止了工作，在那之后直到现在我都在努力解决这个问题。任何帮助将不胜感激。

这是我的代码：

// 在应用程序委托中

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler{

    handler(UIBackgroundFetchResultNewData);
    [[RemoteNotification sharedInstance] pushNotificationReceived:userInfo];

}

//远程通知模式

- (void)  pushNotificationReceived:(NSDictionary *) userInfo
  {
   [self registerBackgroundTaskHandler];
   //get the location here, or start getting the location
   locationManager = [[CLLocationManager alloc] init];
   locationManager.desiredAccuracy= kCLLocationAccuracyBest;
   locationManager.delegate = self;
   [locationManager startUpdatingLocation];
 }


- (void) registerBackgroundTaskHandler
  {
    __block UIApplication *app = [UIApplication sharedApplication];

    self.backgroundTaskId = [app     beginBackgroundTaskWithExpirationHandler:^{
    [app endBackgroundTask:self.backgroundTaskId];
    self.backgroundTaskId = 0;
}];
}


- (void) endBackgroundTask
  {
  if (self.backgroundTaskId)
   {
      UIApplication *app = [UIApplication sharedApplication];
      [app endBackgroundTask:self.backgroundTaskId];
      self.backgroundTaskId = 0;
   }
}

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{

   [locationManager stopUpdatingLocation];
   [[DHWebservices sharedInstance] sendLocationWithLocation:[locations objectAtIndex:0] success:^(NSDictionary *data) {
    [self endBackgroundTask];
   } errorBlock:^(id error) {

  }];

}

我正在使用 Firebase 使用邮递员发送通知。

这是我的通知格式：

{
 "to" : "fF97NwwMTvw:APA91bERqtpIxpSVXNujO_Wl1dVuPXuaJyNP2ygtVlNXxp618ykSubhQZXnh5BS3VPkqdto0lzPzJtQIzR0OIgq8oFZAuhhWfdWim5XRlxv3ut9Y1QGzu6VafNU3OqU8pJT75gg9J3-g",
 "content_available": true,
"priority": "high",
"data" : {
  "key1" : "abc",
  "key2" : 123
}
}
