Greatly simplified conversions between zoom level and altitude. Adjusted field of view to more closely match MapKit. Conversions are now well within the same order of magnitude as MapKit at all latitudes.
Fixes#2266.
For consistency with -setCamera:…, a duration of 0 jumps instantaneously to the new location, while a negative value uses the distance-dependent default.
Due to the produced curve and applied easing, flyTo() doesn’t model a parabola or ballistic trajectory, but it does simulate powered flight to some extent.
Exposed Map::addCustomLayer() publicly as an undocumented, block-based API. This change avoids the terms “layer”, “initialize”, “render”, and “altitude” because they overload existing terminology in the SDK, UIKit, or MapKit. (“Layer” is qualified as “style layer”.) There are outstanding questions about ARC memory management, but this approach works in both Objective-C and Swift for pure OpenGL programming.
Added a demo to iosapp that draws a green layer below any labels in Mapbox Streets.
platform-osx now vends a real NSView subclass, MGLMapView, that is readily embedded inside a Cocoa application for OS X. MGLMapView is backed by an NSOpenGLLayer for optimal performance and integration with other layer-backed views. It supports keyboard shortcuts and several gestures and hosts attribution, zooming, and rotation controls as subviews. osxapp is now a bona fide Cocoa application that embeds MGLMapView inside a XIB. osxapp has preferences and a share button for tight integration with custom styles.
Enabling asynchronous rendering would be more consistent with iOS but increases CPU usage so much, even when idle, that it isn’t worth any performance gain. The bigger issue is that VAOs aren’t being used.
make xpackage creates a static library similar to the one created by make ipackage. make clean cleans additional places where build output ends up.
The OS X minimum deployment target has been increased from 10.9 to 10.10. osxapp’s window has a full size content view, which requires 10.10. Lightweight generics require iOS 9+ and OS X 10.11 regardless, because it was only in that release that Foundation collection classes started adopting lightweight generics.
Shuffled files around and refactored annotations so that iOS and OS X share a good chunk of the annotations code, which now takes advantage of polymorphism. MGLMapView can now display annotations but cannot yet select them. In osxapp, a long press drops a pin, and so does the map view’s context menu.
Annotations have NSPopovers as callouts, and their view controllers can be customized. Annotation image alignment rects are respected for hit testing purposes and for positioning the callout anchor. Callouts in osxapp demonstrate the use of bindings to keep callouts in sync with underlying model objects.
If you tap near a tight cluster of annotations, the annotation directly beneath your finger should be selected first. Previously, the annotations within the query bounds would be selected in order from oldest to newest, which was counterintuitive. The new behavior does sometimes make it more difficult to cycle through the entire cluster, but the previous behavior often got in the way anyways, as your finger would wind up atop a callout view for an annotation farther south.
Also updated the changelog.
Decreased hit test padding for annotation selection, since the query no longer depends on it. Fixed an assertion failure when selecting an annotation while the user dot is selected. Fixed an issue where selecting a selected user dot deselected it. Fixed an issue where the user dot’s callout positioning rect was off-center and a little too high.
MGLMapView now maps “annotation tags” (Cocoa-speak for numeric annotation IDs) to context objects that pair annotations with their identifiers. Previously, MGLMapView mapped the annotation objects themselves to context objects that contained annotation IDs, but this caused most operations involving annotations to be rather expensive: since mbgl tracks annotations by ID, most of the time you know the ID and need either the annotation or some piece of metadata about it.
Along for the ride, geographic methods and support for alignment rect insets on annotation images have been ported from #3135 for OS X. Hit testing now works much like in #3135, with the exception that UIKit doesn’t support hit testing based on pixel opacity. -convertRect:toLatLngBoundsFromView: returns a world-spanning bounds when the world is wrapping.
Fixes#3159.
Added transition frame and finish functions to CameraOptions. Added Objective-C equivalents to the three main entry points to easeTo() in MGLMapView.
Fixes#1581.
Coalescing willChange/didChange notifications means keeping track of how many gestures are currently in progress; a boolean isn’t enough to track this state. This change refactors the gesture recognizers, making them more consistent with each other and more consistent in the case where more than one of them has fired. It also explicitly cancels transitions before all programmatic viewport-modifying methods, since mbgl only does so when animating.
Fixes#2313, fixes#2379, fixes#3062.
