This updates the code generation for style layers to add a test to check that the style object returned from mbgl can be safely cast into the expected type so ownership can be returned to the caller when removing layers. This scenario was previously possible if a layer of type T was added before a layer of type U but both layers shared the same identifier. In that case, if the pointer to the second layer of type U was used to remove a layer, a runtime exception would occur since mbgl returns the layer with type T (the first one added). Now, an exception will still occur if layers with the same identifier are manipulated as described above but it is done as part of a validation check for all public style layer methods at the Darwin platform level. The NSException attempts to warn developers about using and reusing style identifiers to avoid this issue in the first place.
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 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 macOS. 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 macOS SDK | Objective-C, Swift, or AppleScript |  |
| node-mapbox-gl-native | Node.js |  |
| Mapbox Qt SDK | C++03 |  |
Additional Mapbox GL Native–based libraries for hybrid applications are developed outside of this repository:
| Toolkit | Android | iOS | Developer |
|---|---|---|---|
| React Native (npm) | ✅ | ✅ | |
| Apache Cordova (npm) | ✅ | ✅ | Telerik |
| NativeScript (npm) | ✅ | ✅ | Telerik |
| Xamarin | ✅ | ✅ | Xamarin |
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
