Answer 1

对于那些试图迅速做到这一点的人.

if CLLocationManager.locationServicesEnabled() {
    switch(CLLocationManager.authorizationStatus()) {
    case .NotDetermined, .Restricted, .Denied:
        println("No access")
    case .AuthorizedAlways, .AuthorizedWhenInUse:
        println("Access")
    default:
        println("...")
    }
} else {
    println("Location services are not enabled")
}

在locationManager:didFailWithError:,

添加这个：

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


    if([CLLocationManager locationServicesEnabled])
    {
        NSLog(@"Enabled");

        if([CLLocationManager authorizationStatus]==kCLAuthorizationStatusDenied)
        {
             NSLog(@"Permission Denied");
        }
    }
 }
