check wheather gps is available or not in iphone

Question

hi i am making an app based on gps... i have tested it and working fine in iphone simulator 3.0..

but when gps is not available i want to generate an alert...(i just remove the internet connection) i used following method but did not work....

• (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {

  NSLog(@"Error: %@", [error description]);

  UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error getting Current Location" message:@"Please check your Internet connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; [alertView show]; [alertView release];

} so please tell me how to do that (currently working iphone 3.0)

and please also tell if i shift this app.to iphone 4 will it work...asking because i have listen that iphone 4 has gps problem... for this i tried this on simulator 4.0...but it failed...

Answer 1

The GPS on the iphone, or any device for that matter, does not depend having an internet connection.
