http://stackoverflow.com/questions/4119117/restrict-mkmapview-scrolling manually. First make sure your MKOverlay object implements the boundingMapRect property. That can then be used in the regionDidChangeAnimated delegate method to manually adjust the view as needed. Here's an example of how this could be done. Code below should be.. BOOL animated if manuallyChangingMapRect return lastGoodMapRect mapView.visibleMapRect void mapView MKMapView mapView regionDidChangeAnimated BOOL animated if manuallyChangingMapRect prevents possible infinite recursion when we call setVisibleMapRect below return.. this method void mapView MKMapView mapView regionWillChangeAnimated BOOL animated void mapView MKMapView mapView regionDidChangeAnimated BOOL animated prevents possible infinite recursion when we call setVisibleMapRect below if manuallyChangingMapRect return..

I want these to always show the same area. I achieve this now using the regionDidChangeAnimated delegate method. This does not always work that great sometimes the regions are different after zooming and there is a lag.. the gesture recognizer action handler will fire multiple times while the user is panning the map unlike regionDidChangeAnimated which fires only when the pan is finished. You'll need to add a gesture recognizer to one or both maps and implement your..
