iOS 8 Parse.com update and pf geopoint current location - ios

Question

So I recently updated to the latest Parse SDK that's compatible with iOS 8 and I add the two keys NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription...but for some reason [PFGeoPoint geopointForCurrentLocationInBackground] is not being called....and I don't understand why.
and here is a snippet of the code:
[PFGeoPoint geoPointForCurrentLocationInBackground:^(PFGeoPoint *geoPoint, NSError *error) {
if(!error){
NSLog(#"Got current geopoint!");
....
else{
UIAlertView *errorAlert = [[UIAlertView alloc]initWithTitle:#"Oops!" message:[error description] delegate:self cancelButtonTitle:nil otherButtonTitles:#"Okay", nil];
[errorAlert show]; }
}];
Can someone help please?

[PFGeoPoint geopointForCurrentLocationInBackground] will only be called if you have first called your CLLocationManager engaged and have asked the user for permission to show their location.
You also need to update the (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status method for iOS 8.
Something like this is what I use:
// Check for iOS 8. Without this guard the code will crash with "unknown selector" on iOS 7.
if ([self.locationManager respondsToSelector:#selector(requestWhenInUseAuthorization)]) {
[self.locationManager requestWhenInUseAuthorization];
}
else {
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLLocationAccuracyNearestTenMeters;
[locationManager startUpdatingLocation];
//<<PUT YOUR CODE HERE AFTER LOCATION IS UPDATING>>
}
You also need to implement the locationmanager delegate method to handle changes is location authorization status, like so:
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
switch (status) {
case kCLAuthorizationStatusDenied:
NSLog(#"kCLAuthorizationStatusDenied");
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Location Services Not Enabled" message:#"The app can’t access your current location.\n\nTo enable, please turn on location access in the Settings app under Location Services." delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alertView show];
}
break;
case kCLAuthorizationStatusAuthorizedWhenInUse:
{
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLLocationAccuracyNearestTenMeters;
[locationManager startUpdatingLocation];
CLLocation *currentLocation = locationManager.location;
if (currentLocation) {
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate setCurrentLocation:currentLocation];
}
}
break;
case kCLAuthorizationStatusAuthorizedAlways:
{
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLLocationAccuracyNearestTenMeters;
[locationManager startUpdatingLocation];
CLLocation *currentLocation = locationManager.location;
if (currentLocation) {
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate setCurrentLocation:currentLocation];
}
}
break;
case kCLAuthorizationStatusNotDetermined:
NSLog(#"kCLAuthorizationStatusNotDetermined");
break;
case kCLAuthorizationStatusRestricted:
NSLog(#"kCLAuthorizationStatusRestricted");
break;
}
}
