I'm not sure about MKMapView but if it behaves the same way UIScrollView does... are those rects proportional to the view bounds? I'm asking this because UIScrollView does an AspectFit to the rect you pass in when zooming, so to have complete control of where you want the final bounds to be, you need to pass a proportional rect. > > Miguel Arroz > > _______________________________________________ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > http://lists.apple.com/mailman/options/cocoa-dev/pfca%40mega.ist.utl.pt > > This email sent to p...@mega.ist.utl.pt _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
