When using a subclass of `MGLAnnotationView` or `MGLAnnotationImage`, the following warning occurs:
`Incompatible pointer types initializing 'MyClassName *' with an expression of type 'MGLAnnotationView * _Nullable'`
This change eliminates the warning and matches Apple's implementation of `UITableViewCell`.
* [ios] Support for a customizable zoom gesture centering strategy.
We introduce a new MGLZoomGestureCentering enum and corresponding zoomGestureCentering property on MGLMapView.
Currently, Mapbox automatically adjusts the center of the map relative to the user's gesture location, but for some applications (e.g Uber, Lyft) it is preferable to keep the map center "locked" in response to zoom gestures.
Exisiting code will retain its current behavior without modification and will implicitly use the default value of MGLZoomGestureCenteringFollowsTouch. New code can specify MGLZoomGestureCenteringLockedInPlace to get the new "locked" behavior.
* [ios] Added -anchorPointForGesture: to MGLMapView
Ignore multipoints (as opposed to polylines and polygons) when adding annotations, just like we ignore multipolylines, multipolygons, and shape collections.
In osxapp, break multipoint features into points before adding them as annotations.
Ignore any multipolyline, multipolygon, or shape collection object passed into -addAnnotation: or -addAnnotations:. Previously, these methods broke apart the compound shape into its constituent shapes in order to recursively add them to the map. But that broke assumptions about a one-to-one correspondence between annotations and their contexts during selection and deletion.
Added methods to MGLMapView that return the rendered features at a visible point or within a visible rectangle on the map, optionally restricted to a set of layers, plus voluminous documentation.
Added several new geometry classes corresponding to distinct geometry types supported by geometry.hpp. Added parallel “feature” classes to represent these geometries along with tags (IDs) and attributes (properties) from the source.
Grouped classes in the Foundation and SDK groups by theme.
In iosapp, dropped pins’ callout views now display the name of the topmost named feature at that point.
In osxapp, a long press on the map highlights the features under the cursor. Dropping a pin via the menu or context menu item shows the usual dropped pin, but the pin’s title is now the name of a feature under the cursor, if available, rather than “Dropped Pin”.
Fixes the iOS/OS X side of #352.
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.
