I saw in an O’Reilly tutorial the following alerts:

2. http://answers.oreilly.com/uploads/monthly_10_2009/post-48-125435525931_thumb.jpg

I don’t understand how to trigger these alerts. Please could you inform me? The app using ios6

Answer 1

This is the alert when access your current location , this will automatically ask when you access user current location using CLLocationManager

-(void)getLocation
{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLLocationAccuracyHundredMeters;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    NSLog(@"eee%f",locationManager.location.coordinate.latitude);
    // Start updating location changes.
    [locationManager startUpdatingLocation];
}


- (void)startUpdatingCurrentLocation
{
    //NSLog(@"STARTUPDATELOCATION");
    // if location services are restricted do nothing
    if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied ||
        [CLLocationManager authorizationStatus] == kCLAuthorizationStatusRestricted )
    {
        return;
    }

    // if locationManager does not currently exist, create it
    if (!locationManager)
    {
        locationManager = [[CLLocationManager alloc] init];
        [locationManager setDelegate:self];
        locationManager.distanceFilter = 10.0f; // we don't need to be any more accurate than 10m


    }

    [locationManager startUpdatingLocation];

    // [self showCurrentLocationSpinner:YES];
}

Just read CLLocationManager Class Reference for more info
