After trying different ways of limited MKMapView I’ve concluded that using mapDidChange, and resetting if you’re center point goes outside of the boundaries works best, with animated: YES
Here’s how I do it (Using the New Zealand lat/Long span/center).
- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated{
if ((mapView.region.span.latitudeDelta > 15.589921 ) || (mapView.region.span.longitudeDelta > 175.836914) ) {
CLLocationCoordinate2D centerCoord = CLLocationCoordinate2DMake(-41.162114, 172.836914);
MKCoordinateSpan spanOfNZ = MKCoordinateSpanMake(13.589921, 14.062500 );
MKCoordinateRegion NZRegion = MKCoordinateRegionMake(centerCoord, spanOfNZ);
[mapView setRegion: NZRegion animated: YES];
}
if (abs(abs(mapView.region.center.latitude) - 41.162114) > (13.589921 / 2) ) {
CLLocationCoordinate2D centerCoord = CLLocationCoordinate2DMake(-41.162114, 172.836914);
MKCoordinateSpan spanOfNZ = MKCoordinateSpanMake(13.589921, 14.062500 );
MKCoordinateRegion NZRegion = MKCoordinateRegionMake(centerCoord, spanOfNZ);
[mapView setRegion: NZRegion animated: YES];
}
if (abs(abs(mapView.region.center.longitude) - 172.836914) > (14.062500 / 2) ) {
CLLocationCoordinate2D centerCoord = CLLocationCoordinate2DMake(-41.162114, 172.836914);
MKCoordinateSpan spanOfNZ = MKCoordinateSpanMake(13.589921, 14.062500 );
MKCoordinateRegion NZRegion = MKCoordinateRegionMake(centerCoord, spanOfNZ);
[mapView setRegion: NZRegion animated: YES];
}
}
