cocoa touch - Core Location not working in iOS 8

I'm trying to use significant change location monitoring in iOS 8, but the didUpdateLocations method is never called. Here is the code for setting up the location manager:

- (void)viewDidLoad
{
    [super viewDidLoad];
    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    [locationManager requestWhenInUseAuthorization];
    [locationManager startMonitoringSignificantLocationChanges];
}

Despite calling requestWhenInUseAuthorization, nothing pops up to ask the user to authorize it. I have set NSLocationWhenInUseUsageDescription, and it still does not work. didChangeAuthorizationStatus and didFailWithError are also never called. EDIT: I was able to get it to ask the user to allow location services, but even if you click allow it never shows the location.

See Question&Answers more detail:os

There is currently a bug in iOS8 beta5 which always deactivate geolocation service for your app (at least for mine).

Go in settings > Privacy > Location services > Your app > Always.

But I don't know why, but even if you set it to Always this setting will auto-deactivate, so please be patient and often return in the settings to configure again your app location.
