实施这个：

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
    if (status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse) {
        //allowed - do your logic
    }
    else if (status == kCLAuthorizationStatusDenied) {
        //denied
    }
}

Swift 2.2：

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    if status == .AuthorizedAlways || status == .AuthorizedWhenInUse {
        //allowed - do your logic
    }
    else if status == .Denied {
        //denied
    }
}

Swift 3.0：

func locationManager(_ manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    if status == .AuthorizedAlways || status == .AuthorizedWhenInUse {
        //allowed - do your logic
    }
    else if status == .Denied {
        //denied
    }
}

请记住设置您的代理：

self.locationManager.delegate = self;

并由您的班级实施：CLLocationManagerDelegate
