* [ios, macos] Audited source headers for nullability
* [macos] Made MGLTileSet public
* [ios, macos] Replaced MGLTileSet with MGLTileSource
MGLRasterSource and MGLVectorSource now share a common abstract superclass, MGLTileSource. MGLTileSet has been removed. MGLTileSource is modeled after mbgl::style::RasterSource and mbgl::style::VectorSource. It has initializers that incorporate the parameters of MGLTileSet’s initializers, but it lacks getters for everything but the attribution string. MGLTileSet’s properties have been converted into options that can be passed into MGLTileSource’s initializers in a dictionary.
Properly implement rawSource as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLSource from setting _rawSource directly but getting a different value out of self.rawSource.
Marked -[MGLSource init] as unavailable and ensured that concrete subclasses of MGLSource have the right set of initializers marked as designated initializers.
Documentation comments for each concrete source class identify the corresponding source type in the style specification. Clarified the purpose of MGLTileSetScheme, now known as MGLTileCoordinateSystem.
* [ios, macos] Clarified tile size interpretation
Sticking to a default value of 256 for mapbox: URLs, but other URLs get the standard 512 value.
* [ios, macos] rawSource is always set
* [ios, macos] Cleaned up MGLShapeSource initialization
rawSource is never nil, so there’s no need for a -commonInit method. Extracted -geoJSONOptions from MGLShapeSource into a standalone function for easier testing.
* [ios, macos] Synchronized headers in project
Realphabetized headers in groups. Added headers missing from one project or the other.
* [ios, macos] Added MGLShape methods to (de)serialize GeoJSON data
Added a class initializer and instance method to MGLShape that deserialize and serialize the shape as GeoJSON data, respectively. The new initializer handles parsing errors gracefully.
Removed methods specific to GeoJSON data from MGLShapeSource, in an effort to reduce parallel state. Developers are now expected to go through the new MGLShape initializer to get an MGLShape representation. Alternatively, a local file URL can be passed into the other MGLShapeSource initializer.
* [ios, macos] Typo in assertion message
* [ios, macos] Simplified GeoJSON serialization
Every MGLShape now knows its most specific mbgl::GeoJSON representation.
* [ios, macos] Reremoved MGLFeaturePrivate
mbgl::GeoJSON, which is a variant, allows a single GeoJSON representation method to traffic in whatever type is needed for a particular shape class. This change removes some hidden private protocols, which are a bug waiting to happen.
* [ios, macos] Fixed covariant rawLayer property
Properly implement rawLayer as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLStyleLayer from setting _rawLayer directly but getting a different value out of self.rawLayer.
* [ios, macos] Use MGLAttributionInfo for source attribution
Made MGLAttributionInfo public. Replaced MGLTileSource’s attribution property with an attributionInfos property set to an array of MGLAttributionInfo objects. Added an MGLTileSourceOption for specifying an array of MGLAttributionInfo objects instead of an HTML string (either is acceptable when creating an MGLTileSource).
* [ios, macos] Corrected method references in documentation
* [ios, macos] Refer to template images in documentation
SDF icons are known as template images in AppKit and UIKit.
* [ios, macos] Override property names in requirements
This checks the kind of MGLShape passed into the source and, if it
is a feature, it mbgl feature objects to pass to core. This keeps the
feature id and attributes data intact. If the shape is a
`MGLShapeCollectionFeature` it creates an `mbgl::FeatureCollection`
object (also to keep feature properties). If the shape is not any
sort of feature, it passes along just the geometry.
This also uses the MGLFeatureFromMBGLFeature converter for the case where
GeoJSON data passed in to a source contains a single feature. The
converter has logic to keep the id and attributes properties intact.
Before, these properties were lost because only geometry conversion
was done.
Finally, logic to handle (and associated tests) of nested shape
collection features is removed since that is not supported by
the GeoJSON spec or the core implementation.
[ios] Add test of drawing plain shape to iosapp
* [ios, macos] Source-driven attribution
Refactored MGLSource initialization. Implemented a new private class, MGLAttributionInfo, that parses an HTML attribution string from TileJSON and stores the resulting structured data. Added methods to MGLTileSet and MGLStyle to aggregate MGLAttributionInfos.
On macOS, update the attribution view as soon as the source attribution changes. On iOS, fetch the current attribution information when displaying the action sheet.
Removed hard-coded attribution strings.
* [macos] Respect inline formatting in attribution HTML
Apply a default font and color to attribution HTML as it is imported into an attributed string. Pass the attributed string into MGLAttributionButton as is, without stripping formatting. Avoid overriding the font and color after importing the HTML, in case these attributes are explicitly specified rather than intrinsic to a hyperlink.
Constrain the top of the attribution view to all the attribution buttons, in case one of them needs additional headspace.
* [ios, macos] Display unlinked attribution strings
Unlinked attribution strings are represented on macOS as buttons that have the default cursor and do nothing when clicked. On iOS, they are action sheet buttons that do nothing but dismiss the action sheet.
* [macos] Fixed random Auto Layout exception
Auto Layout randomly finds itself unable to satisfy constraints when updating attribution, due to some spurious constraints between attribution buttons. Regenerate the entire attribution view every time the source attribution changes.
* [ios, macos] Thoroughly dedupe attribution infos
Also added a test to verify parity with the GL JS implementation. This implementation avoids sorting.
* [ios, macos] Trim whitespace from attribution strings
Also added parsing tests.
* [ios, macos] Added attribution parsing tests for styles
Included an emoji test to ensure that attribution strings are interpreted as UTF-8, to avoid mojibake. Included a test of removing the underline from a leading copyright symbol.
* [ios, macos] Derive feedback link from source
MGLAttributionInfo now detects feedback links in the attribution HTML code, and it is responsible for tailoring the feedback URL to the current viewport.
Removed the hard-coded feedback action from the attribution sheet on iOS in favor of a source-derived feedback title and URL. Moved the feedback action from macosapp to MGLMapView; applications are now expected to hook an Improve This Map menu item to an MGLMapView action.
