A new MGLTileSet class that wraps all available core Tileset options can be created and passed into the sources. The sources pass that tileset object along to core.
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.
This paves the way for updates to filter and layout properties to trigger a source reload, without each SDK having to participate in the implementation.
Clang/Sourcekitten do not appear to like HTML tags in `@param` definitions.
Also:
- Wraps lines at 80 chars.
- Adds minimal docs for MGLGeoJSONSource so it will be seen by jazzy.
This removes a previous implementation of geojson options that used
a new type to transfer the data around. Added in its place is
an options API that takes an NSDictionary that works similarly to
NSAttributedString and many other Cocoa APIs that take options.
The options parser now expects the developer to send values of the
type noted in the documentation and it simply converts the NSNumber
to the correct type (integer, double, or bool) for mbgl. However, an
exception is raised if the value is not an NSNumber.
We convert NSNumbers (and NSStrings) to the appropriate mbgl value
so that we can use NSPredicates to describe mbgl filters we want
to apply to style layers at runtime.
This change fixes an issue where
the conversion from an NSNumber that represented a bool was not
recognized as such. encode(bool) returns a 'c' or 'b' on 32 bit and
64 bit systems respectively and objCType of an NSNumber representing
a bool always returns 'c'. Now the implementation checks for 'c'
always and NSNumbers representing bool don't fall through and
trigger the exception.
Duplicate each color-typed property once per platform using conditional compilation macros. Let’s just hope we never have to throw CGColor into the mix.
The documentation for runtime style API properties now spells out the value of the default type, to help developers infer the type of the property itself.
* [ios, macos] Move debug mask options to shared header
* Limit buffer debug modes to macOS
... because these modes use OpenGL features that aren't supported by iOS.
* Try a different tact: exclude "iPhone"
... which is actually all iOS-like devices.
* [ios, macos] Fixed typo in color property docs
* [ios, macos] Predefined colors as default color property values
Use {NS,UI}Color.blackColor and {NS,UI}Color.whiteColor as aliases for common default color values.
An offset style attribute is now exposed publicly as an NSValue representing a CGVector instead of an NSArray of NSNumbers. A padding style attribute is now exposed publicly as an NSValue representing an NSEdgeInsets or UIEdgeInsets instead of an NSArray of NSNumbers. This change also fixes round-tripping of padding values due to a difference between the style specification and Foundation regarding the order of edges around a box. Used a designated initializer on NSEdgeInsets/UIEdgeInsets to ensure correct order when converting from C++ to Objective-C.
Fixes#5947, fixes#6065.
- Removes nullability shims for Xcode 6.
- Removes MGLTypes.h from files where it was only being used for
nullability support.
- Accepts that `NS_SWIFT_NAME` is not fully supported by Xcode 7.2 and
lower.
- Adds documentation about Xcode 7.3 requirement.
MGLGeoJSONSource can now be initialized with GeoJSON data. Replaced the data property with a geoJSONData property and added features and URL properties alongside it. Each property may be set or unset based on how the object was initialized.
Fixes#5965, fixes#5966.
