title: Getting user location not working?
body: <p>I am new to the MapView topic.Now I am working on the map view.I am getting the san Francisco location longitude and latitude values.I am testing in the simulator.It is not showing the current location longitude and latitude values.</p>
  
  <p>With the help of this tutorial <code>http://www.creativeworkline.com/2014/12/core-location-manager-ios-8-fetching-location-background/</code> I am developing the app.</p>
  
  <p>In AppDelegate file I wrote the following code like this</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
  
       UIAlertView * alert;
  
      //We have to make sure that the Background App Refresh is enable for the Location updates to work in the background.
      if([[UIApplication sharedApplication] backgroundRefreshStatus] == UIBackgroundRefreshStatusDenied){
  
          alert = [[UIAlertView alloc]initWithTitle:@""
                                            message:@"The app doesn't work without the Background App Refresh enabled. To turn it on, go to Settings &gt; General &gt; Background App Refresh"
                                           delegate:nil
                                  cancelButtonTitle:@"Ok"
                                  otherButtonTitles:nil, nil];
          [alert show];
  
      }else if([[UIApplication sharedApplication] backgroundRefreshStatus] == UIBackgroundRefreshStatusRestricted){
  
          alert = [[UIAlertView alloc]initWithTitle:@""
                                            message:@"The functions of this app are limited because the Background App Refresh is disable."
                                           delegate:nil
                                  cancelButtonTitle:@"Ok"
                                  otherButtonTitles:nil, nil];
          [alert show];
  
      } else{
  
          self.locationTracker = [[LocationTracker alloc]init];
          [self.locationTracker startLocationTracking];
  
          //Send the best location to server every 60 seconds
          //You may adjust the time interval depends on the need of your app.
          NSTimeInterval time = 60.0;
          self.locationUpdateTimer =
          [NSTimer scheduledTimerWithTimeInterval:time
                                           target:self
                                         selector:@selector(updateLocation)
                                         userInfo:nil
                                          repeats:YES];
      }
  
      return YES;
  }
  </code></pre>
  
  <p>I have imported Location Tracker class in my ViewController</p>
  
  <p>and I wrote the following code to get the location name and addresss</p>
  
  <pre><code> CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
      __block NSString *returnAddress = nil;
  
      [geoCoder reverseGeocodeLocation:self.appDelgate.locationTracker.myLastLocation_ completionHandler:^(NSArray *placemarks, NSError *error) {
  
          CLPlacemark *placemark = [placemarks lastObject];
  
          if (placemark)
          {
              returnAddress = [NSString stringWithFormat:@"%@ %@",placemark.subLocality,placemark.subAdministrativeArea];
              [[NSUserDefaults standardUserDefaults] setObject:[NSString stringWithString:returnAddress] forKey:@"address"];
  
          }
  
  
      }];
  </code></pre>
  
  <p>Now my problem is that it is not going inside block.So that I am getting the "returnAddress" as (null).</p>
  
  <p>I wrote like this even though it is not coming</p>
  
  <pre><code>- (void)updateLocationToServer {
  
      NSLog(@"updateLocationToServer");
  
      // Find the best location from the array based on accuracy
      NSMutableDictionary * myBestLocation = [[NSMutableDictionary alloc]init];
  
      for(int i=0;i&lt;self.shareModel.myLocationArray.count;i++){
          NSMutableDictionary * currentLocation = [self.shareModel.myLocationArray objectAtIndex:i];
  
          if(i==0)
              myBestLocation = currentLocation;
          else{
              if([[currentLocation objectForKey:ACCURACY]floatValue]&lt;=[[myBestLocation objectForKey:ACCURACY]floatValue]){
                  myBestLocation = currentLocation;
              }
          }
      }
      NSLog(@"My Best location:%@",myBestLocation);
  
      NSLog(@"latitude %@",[myBestLocation valueForKey:@"latitude"]);
  
        NSLog(@"longitude %@",[myBestLocation valueForKey:@"longitude"]);
  
      self.DICT=[NSDictionary dictionaryWithDictionary:myBestLocation];
  
      //If the array is 0, get the last location
      //Sometimes due to network issue or unknown reason, you could not get the location during that  period, the best you can do is sending the last known location to the server
      if(self.shareModel.myLocationArray.count==0)
      {
          NSLog(@"Unable to get location, use the last known location");
  
          self.myLocation=self.myLastLocation;
          self.myLocationAccuracy=self.myLastLocationAccuracy;
  
      }else{
          CLLocationCoordinate2D theBestLocation;
          theBestLocation.latitude =[[myBestLocation objectForKey:LATITUDE]floatValue];
          theBestLocation.longitude =[[myBestLocation objectForKey:LONGITUDE]floatValue];
          self.myLocation=theBestLocation;
          self.myLocationAccuracy =[[myBestLocation objectForKey:ACCURACY]floatValue];
      }
  
      NSLog(@"Send to Server: Latitude(%f) Longitude(%f) Accuracy(%f)",self.myLocation.latitude, self.myLocation.longitude,self.myLocationAccuracy);
  
         //TODO: Your code to send the self.myLocation and self.myLocationAccuracy to your server
  
      //After sending the location to the server successful, remember to clear the current array with the following code. It is to make sure that you clear up old location in the array and add the new locations from locationManager
      [self.shareModel.myLocationArray removeAllObjects];
      self.shareModel.myLocationArray = nil;
      self.shareModel.myLocationArray = [[NSMutableArray alloc]init];
  
      CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
      __block NSString *returnAddress = nil;
     self.locationActual = [[CLLocation alloc]initWithLatitude:[[myBestLocation objectForKey:LATITUDE]floatValue] longitude:[[myBestLocation objectForKey:LONGITUDE]floatValue]];
  
      //CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
     // __block NSString *returnAddress = nil;
  
      CLLocation *locloc = [[CLLocation alloc] initWithLatitude:[[myBestLocation objectForKey:LATITUDE]floatValue] longitude:[[myBestLocation objectForKey:LONGITUDE]floatValue]];
  
      [geoCoder reverseGeocodeLocation:locloc completionHandler:^(NSArray *placemarks, NSError *error) {
  
          CLPlacemark *placemark = [placemarks lastObject];
  
          if (placemark)
          {
              returnAddress = [NSString stringWithFormat:@"%@ %@",placemark.subLocality,placemark.subAdministrativeArea];

              UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"" message:returnAddress delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
              [alertView show];
          }
  
  
      }];
  
  
    }
