Add an UIView subclass that can be used as the base class for all client provided UIViews for annotations. Teach MGLMapView to be able to display annotation views over the map if provided by the client delegate. For now, if the delegate provides a UIView then it will be used. If not, the map view will fall back to the old strategy of using GL annotations with an image provided by the delegate or a default image if not. The map keeps a reuse queue and will store annotation views that are panned offscreen in the queue if the application developer supplied a reuse queue identifer. The views in the queue are reused when more annotation views are required. This view reuse provides a performance gain when many annotations are shown and most of them are offscreen. iosapp now implements the new delegate method to supply a native view. Add a playground to the workspace to facilitate experimentation with new features. A playground is capable of importing frameworks if it exists in the same workspace that builds the imported framework. The initial playground demonstrates annotation views. This also fixes a crash due to nullptr in annotations array If the `annotations` method is called while the user dot's callout view was showing, the userdot annotation is represented as null in the annotation context map. This caused a crash when the null pointer was attempted to be converted into an NSArray via C array. This protects against this bug by filtering out such a null annotation.
Mapbox GL Native
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox GL Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.
The Mapbox GL ecosystem
This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a GLFW-based demo application for Ubuntu Linux and OS X. The SDKs target the usual languages on their respective platforms:
| SDK | Languages | Build status |
|---|---|---|
| Mapbox GL Native | C++14 |   |
| Mapbox Android SDK | Java |  |
| Mapbox iOS SDK | Objective-C or Swift |  |
| Mapbox OS X SDK | Objective-C or Swift |  |
| node-mapbox-gl-native | Node.js | /  |
| Mapbox Qt SDK | C++03 | |
Additional Mapbox GL Native–based libraries are developed outside of this repository:
- React Native Mapbox GL for React Native applications on iOS and Android
- Telerik’s Mapbox plugin for Apache Cordova Hybrid applications
- Telerik’s Mapbox plugin for NativeScript Hybrid applications
- Xamarin's Mapbox component for Xamarin Hybrid applications
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
