# Mapbox Maps SDK for iOS

The Mapbox Maps SDK for iOS is an open-source framework for embedding interactive map views with scalable, customizable vector maps into Cocoa Touch applications on iOS 9.0 and above using Objective-C, Swift, or Interface Builder. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL.

For setup information, check out the Mapbox Maps SDK for iOS homepage. For detailed usage instructions, read “First steps with the Mapbox Maps SDK for iOS” and consult the online examples.
