NSString *countryCode = [[NSLocale currentLocale] objectForKey: NSLocaleCountryCode]; will get you an identifier like e.g. “US” (United States), “ES” (Spain), etc. In Swift 3: let countryCode = NSLocale.current.regionCode In Swift 2.2: let countryCode = NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as String Compared to a solution based on CLLocationManager this approach has pros and cons. The primary con is that it … Read more
If you are using the simulator: Press command + shift + , in Xcode to open the scheme editor Select the Run scheme Go to the Options tab Check ✅ Allow Location Simulation Select a Default Location in the dropdown Selecting None as your Default Location may have caused the problem.
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
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
Since I asked this question, I have done a fair bit of testing (mostly on the train between home and work) and have confirmed that the behaviour for suspended apps is as I suspected at the end of the question. That is, your suspended app is woken up, you don’t receive any callbacks on your … 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
While difficult to track down, the solution for this is quite simple. Through much trial and error I found out that while the location access dialog pops up when you try to access any location services in the app for the first time, the dialog disappears on its own (without any user interaction) if the … 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
