MBXMapKit is a simple, two-file library allowing one-line integration of MapBox custom maps into Apple's MapKit on iOS 7.0+ and OS X 10.9+. No submodules, no linking, no delegates, no resources -- just drag two files into your project and start using MBXMapView in place of MKMapView.
Requirements:
- iOS 7.0+ or OS X 10.9+
- Xcode 5+
- Automatic Reference Counting (ARC)
Check out the overview guide or the API docs for more details.
You might also be interested in the MapBox iOS SDK, which is a ground-up rewrite meant as a replacement for Apple's MapKit, not based on it. If you've always wished MapKit was open source for complete customizability, the MapBox iOS SDK is for you.
