iOS Question

iOS: App is not asking user's permission while installing the app. getting kCLAuthorizationStatusNotDetermined every time - Objective-c & Swift

I am trying to fetch user location in my iOS app. I have included corelocation framework in my project first. Then on a button click I am invoking the core location api as below. When I am trying to install this in a device, the core location never asks the user permission. When I try to fetch the location on button click, I am getting kCLAuthorizationStatusNotDetermined as the authorisationStatus. Please help me in this. I have no clue what is happening.

- (IBAction)fetchLessAccurateLocation:(id)sender {
[self.txtLocation setText:@""];

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
locationManager.distanceFilter = 1000;

if ([self shouldFetchUserLocation]) {
[locationManager startUpdatingLocation];
}
}


This is my shouldFetchUserLocation method:

-(BOOL)shouldFetchUserLocation{

BOOL shouldFetchLocation= NO;

if ([CLLocationManager locationServicesEnabled]) {
switch ([CLLocationManager authorizationStatus]) {
case kCLAuthorizationStatusAuthorized:
shouldFetchLocation= YES;
break;
case kCLAuthorizationStatusDenied:
{
UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Error" message:@"App level settings has been denied" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
alert= nil;
}
break;
case kCLAuthorizationStatusNotDetermined:
{
UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Error" message:@"The user is yet to provide the permission" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
alert= nil;
}
break;
case kCLAuthorizationStatusRestricted:
{
UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Error" message:@"The app is recstricted from using location services." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
alert= nil;
}
break;

default:
break;
}
}
else{
UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Error" message:@"The location services seems to be disabled from the settings." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
alert= nil;
}

return shouldFetchLocation;
}


Here is my core location delegate method:

- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray *)locations __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_6_0){

NSLog(@"location fetched in delegate");

CLLocation* location = [locations lastObject];
NSDate* eventDate = location.timestamp;
NSTimeInterval howRecent = [eventDate timeIntervalSinceNow];

if (abs(howRecent) < 15.0) {
// If the event is recent, do something with it.
NSLog(@"inside loop.... latitude %+.6f, longitude %+.6f\n",
location.coordinate.latitude,
location.coordinate.longitude);
}
NSLog(@"latitude %+.6f, longitude %+.6f\n",
location.coordinate.latitude,
location.coordinate.longitude);
[self.txtLocation setText:[NSString stringWithFormat:@"\nlatitude: %+.6f \nlongitude: %+.6f", location.coordinate.latitude, location.coordinate.longitude]];

[locationManager stopUpdatingLocation];
[locationManager stopMonitoringSignificantLocationChanges];

if(locationManager!=nil){
locationManager.delegate= nil;
locationManager= nil;
}
}

Answer

I was facing the same issue, after re-installing my app it was returning kCLAuthorizationStatusNotDetermined whenever checking for [CLLocationManager authorizationStatus] and the app didn't even show up in Settings > Privacy > Location Services.

The authorization dialog that iOS prompts user to approve access to location services is triggered on [locationManager startUpdatingLocation] which in your case is never called (shouldFetchUserLocation will be always NO).

Miguel C.'s solution seems like a good fix, will try that.

Edit for iOS8.x

When iOS8 came it brought little change in the way CLLocationManager is used. As mentioned few times in other answers it requires additional step comparing to iOS7. Today I faced the issue myself and found this article (it's been referenced from multiple other questions but it completes my earlier answer). Hope it helps!
