Getting user location every n minutes after app goes to background

To anyone else having a nightmare of a time trying to figure this one out, I have a simple solution.

1. Study the example from raywenderlich.com. The sample code works perfectly, but unfortunately there's no timer during background location. This will run indefinitely.

2. Add timer by using this code snippet:

   -(void)applicationDidEnterBackground {  [self.locationManager stopUpdatingLocation];  UIApplication* app = [UIApplication sharedApplication];  bgTask = [app beginBackgroundTaskWithExpirationHandler:^{    [app endBackgroundTask:bgTask];    bgTask = UIBackgroundTaskInvalid;  }];  self.timer = [NSTimer scheduledTimerWithTimeInterval:intervalBackgroundUpdate                                                target:self.locationManager                                              selector:@selector(startUpdatingLocation)                                              userInfo:nil                                               repeats:YES];}

3. Just don't forget to add "App registers for location updates" in info.plist.

After some days trying all possible solutions I was finally able to make it work. Here is what was wrong in my solution:

• I need to setup 2 UIBackgroundTaskIdentifiers, one for the timer, and another one for the locationManager

On my solution, just add:

UIApplication *app = [UIApplication sharedApplication];bgTask2 = [app beginBackgroundTaskWithExpirationHandler:^{ [app endBackgroundTask:bgTask2]; bgTask2 = UIBackgroundTaskInvalid; }];self.locationManager.delegate = self; [self.locationManager startUpdatingLocation]; 

Once you're in the background you can only have 10 minutes of additional time. There is no way to extend that. You should use the location background services instead.
