I have a location app that already successfully asks the user to enable location services, and then can show them their coordinates on a button press as well. So I decided to play around with everything that is available in the CLLocationManager reference provided by xcode.

I decided to setup a bool method called "locationServicesEnabled". It returns a value of YES(1) or NO(0). I declared the method and then went to implement it. I am trying to have NSLog print the bool result out to the console when you open the app.

Here is how I declared the BOOL method in my ViewController.m file:

@interface ViewController () <CLLocationManagerDelegate>


-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations;
+ (BOOL)locationServicesEnabled;

@end

And here is how I implemented the BOOL method in ViewController.m:

+ (BOOL)locationServicesEnabled{

[self locationServicesEnabled];

NSLog(@"%hhd", self.locationServicesEnabled);

return 0;

}

Answer 1

Why do you want to create an extra method? You could minimize the risk of errors by using already available ones: NSLog(@"Location services enabled: %d",[CLLocationManager locationServicesEnabled]);

Answer 2

I think your issue might be the fact that you are calling your function inside its self:

+ (BOOL)locationServicesEnabled
{

     [self locationServicesEnabled]; <- should this be here

     NSLog(@"%hhd", self.locationServicesEnabled);

     return 0;
}
