This new property is explained in the WWDC session “What’s New in Core Location”. The default value is NO if you link against iOS 9. If your app uses location in the background (without showing the blue status bar) you have to set allowsBackgroundLocationUpdates to YES in addition to setting the background mode capability in … Read more
I found the problem/solution. When it is time to start location service and stop background task, background task should be stopped with a delay (I used 1 second). Otherwise location service wont start. Also Location Service should be left ON for a couple of seconds (in my example it is 3 seconds). Another important notice, … Read more
As of iOS 5 MKReverseGeoCoder is Deprecated! So you want to use CLGeocoder with CLLocationManager, very simple and works with block. Example: – (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { [self.locationManager stopUpdatingLocation]; CLGeocoder * geoCoder = [[CLGeocoder alloc] init]; [geoCoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) { for (CLPlacemark *placemark in placemarks) { …. = [placemark … Read more
As of iOS 5, the simulator has a configurable location. Under the Debug menu, the last entry is “Location”; this gives you a sub menu with: None Custom Location Apple Stores Apple City Bicycle Ride City Run Freeway Drive Custom Location lets you enter a Lat/Long value. Bicycle ride, City Run, and Freeway Drive are … Read more
After months of trials and errors by experimenting the Core Location Framework, I have found the solution to get location update even when the app is killed/suspended. It works well for both iOS 7 and 8. Here is the solution:- If your app is a location based mobile application that needs to monitor the location … Read more
Here is the solution that I used to get continuous location from iOS 7 devices no matter it is in foreground or background. You may find the full solution and explanation from blog and also github:- Background Location Update Programming for iOS 7 and 8 Github Project: Background Location Update Programming for iOS 7 and … Read more
It seems that stopUpdatingLocation is what triggers the background watchdog timer, so I replaced it in didUpdateLocation with: [self.locationManager setDesiredAccuracy:kCLLocationAccuracyThreeKilometers]; [self.locationManager setDistanceFilter:99999]; which appears to effectively power down the GPS. The selector for the background NSTimer then becomes: – (void) changeAccuracy { [self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest]; [self.locationManager setDistanceFilter:kCLDistanceFilterNone]; } All I’m doing is periodically toggling the accuracy … Read more
I found a solution to implement this with the help of the Apple Developer Forums: Specify location background mode Create an NSTimer in the background with UIApplication:beginBackgroundTaskWithExpirationHandler: When n is smaller than UIApplication:backgroundTimeRemaining it will work just fine. When n is larger, the location manager should be enabled (and disabled) again before there is no … Read more
