How to detect when MKUserTrackingBarButtonItem is used

I'm currently trying to find a way to detect when the MKUserTrackingBarButtonItem is used, other than deal with the mapView:didUpdateUserLocation: delegate method.

I tried to setAction of the MKUserTrackingBarButtonItem to call my function (check this thread), but of curse it removes the updating location action, which I don't want.

I don't find any delegate method triggered :/

Thanks for any idea.

If your MKUserTrackingBarButtonItem has been assigned a MKMapView to operate on then the map view's delegate will receive mapView:didChangeUserTrackingMode:animated: when the tracking mode is changed (which is done by pressing that button).
