Previously, we declared MGLStyleLayer initializers in the MGLStyleLayer protocol as optional methods. This made it easy to opt in and out of initializers that did or or did not make sense for the subclass. However, this approach was dangerous since it was easy for an application developer to initialize an MGLStyleLayer subclass with an init method that was actually not implemented in that class causing an exception at runtime. This commit moves the init methods that each subclass supports to each subclass so xcode (and the compiler) help the developer avoid the previously possible runtime exception. In addition, a new init method is added that takes the source layer and passes that on to `mbgl::style:Layer` (but only on classes where this is possible in core). This allows an application developer to style a specific source layer (i.e. the contour lines of the mapbox terrain vector source). Finally, this refactors MGLStyleLayer classes to use an MGLSource instead of a string identifier for the source when initializing the style.
Mapbox iOS SDK
A library based on Mapbox GL Native for embedding interactive map views with scalable, customizable vector maps into Cocoa Touch applications on iOS 7.0 and above using Objective-C, Swift, or Interface Builder.
This repository is for day-to-day development of the SDK. Building the SDK yourself requires a number of dependencies and steps that are unnecessary for developing production applications. For production applications, please consider installing an official, prebuilt release instead; see the Mapbox iOS SDK website for installation instructions.
