Question

I have an MKMapView that I am considering rotating in order to more conveniently display a series of Annotations to my users.

As of now I am planning on simply rotating the entire view with a CGAffineTransform, but I wanted to know if anyone had any experience with MKMapView rotation.

• Are there any pitfalls or “gotchas” that you came across when adding rotation?
• Is there an easier way to rotate a mapview?
• If I have an overlay will the convertCoordinate:toPointToView: method still work the same way? I would assume that I’d have to apply the same transform to my overlay for the points to line up, but maybe the method is smarter than that.

If there’s anything that you think could help out I’d love to hear it all.

Edit: After much experimentation I believe that I’ll be using static maps that I can rotate and overlay myself, however, I would still be interested in any information about MKMapView rotation.

That’s a fresh sample of MKMapView rotation with iPhone ccelerometer. Hope it’ll help.
