This method can cause UI unresponsiveness if invoked on the main thread.

Got the following error in Xcode console:

> This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the `-locationManagerDidChangeAuthorization:` callback and checking `authorizationStatus` first.

In:

```Swift
+ (INTULocationServicesState)locationServicesState
{
if ([CLLocationManager locationServicesEnabled] == NO) {
return INTULocationServicesStateDisabled;
}
else if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined) {
return INTULocationServicesStateNotDetermined;
}
else if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {
return INTULocationServicesStateDenied;
}
else if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusRestricted) {
return INTULocationServicesStateRestricted;
}

return INTULocationServicesStateAvailable;
}
```
