Mapbox iOS SDK
This tree of the Mapbox iOS SDK is deprecated in favor of the Mapbox GL-based version 2.0.0 and above. The future of Mapbox maps is vector rendering, and 2.0.0 is a rewrite based on OpenGL ES and vector rendering. Unlimited, per-user Mapbox pricing plans cannot be used with this version of the iOS SDK.
See this doc for the original project details.
