MGLMapView observes changes to the coordinate property of each MGLAnnotation added to it. Changing the coordinate property in a KVO-compliant way causes the annotation to be relocated and its callout view, if present, to be dismissed. To avoid observing the same annotation twice yet also avoid expensive lookups when adding or removing annotations, MGLMapView indexes added point annotations in an NSMutableSet.
In iosapp, tapping a callout view moves the selected annotation to the center of the screen and deselects it.
Fixes#1980.
Added an API for deleting unused annotation images’ images. When you nil out the image of an MGLAnnotationImage, MGLMapView deletes the sprite from the style and recreates any annotation associated with the MGLAnnotationImage instance; the MGLAnnotationImage’s falls back to SDK’s default annotation image.
In iosapp, deselecting an annotation resets its image to the default; deselecting it again restores the image.
ref #3185
If no access token is found in user defaults at launch, iosapp prompts the user for an access token. Renamed the user defaults key for the access token to conform to Cocoa naming conventions.
Fixes#4696.
Now that #4641 has removed the prohibition against C99 extensions, this change removes many pragma statements that suppress warnings about variadic macros and designated initializers. Designated initializers and Elvis operators have been introduced wherever appropriate.
Converted MBXViewController from Objective-C++ to Objective-C. In the process, the dependency on default_styles.hpp was replaced by a hardcoded list of style URLs along with runtime assertions that the list of styles is the right length.
