Add a container view to hold annotations. This gets around a performance
issue with `UIView:addSubview:` where adding views is N^2. It helps
annotation views avoid cutting into callout views when the annotation
views are transformed to be "flat".
MGLPolygon (and by extension MGLMultiPolygon) now supports interior rings. The data is preserved in feature querying results, and interior rings are respected when adding polygon overlays to the map.
Fixes#1729.
[ios, osx] Updated changelog
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.
This adds an option to MGLAnnotationView so that a developer can control
how their annotation views scale in size as they approach the top of
the map view (along the Y axis). The size change is also affected by
the pitch (tilt) of the map view. If there is no tilt then scaling
is not performed. As the map is tilted scaling is gradually applied.
This turns the MGLAnnotationView implementation into an Objective C++
class so that SDK constants from C++ files can be used.
The new behavior is enabled by default to maintain consistency with
annotations backed by GL sprites. The MBXViewController redundantly
sets the new property as an illustration of use.
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.
Renamed MGLStyleCurrentVersion to MGLStyleDefaultVersion to emphasize the constant’s role as an indicator of the default version used by SDK classes, which may be behind depending on release schedules. In the documentation for each style URL method, include the actual version number instead of the constant. In unit tests, verify that this documentation is in sync with the constant.
Link each style URL method’s documentation to a forthcoming webpage on mapbox.com that describes the style in rich detail.
Updated default styles from v8 to v9. Deprecated the MGLMapView class methods in favor of new methods that take a version parameter. Deprecated Emerald outright in favor of Outdoors. Replaced usage of the unversioned MGLStyle methods with the corresponding versioned methods and MGLStyleCurrentVersion to ensure consistency.
Expanded MGLStyle unit tests to also assert that MGLStyle has the right number of style URL methods and that they’re all public. Linked the OS X SDK unit test bundle to libmbgl-core.a. Removed an unnecessary dependency on osxapp.
Replaced Emerald with Outdoors in iosapp and osxapp.
Fixes the iOS and OS X side of #4577 and #4702.
Fixed an issue where the “return to map” accessibility element lacked a label. Always update the title and subtitle of an annotation accessibility element, in case the title or subtitle changes from one showing to the next.
Added a hint for annotations. Use declarative rather than imperative for hints.
Marked the map view and its annotations as adjustable so that swiping up and down with VoiceOver zooms out and in, respectively.
Added accessibility values to toolbar buttons in iosapp.
Via nfarina/calloutview#84, SMCalloutView is now accessible. Activating a focused annotation now shows its callout view and focuses its left accessory view, if present, or the title view. There is a “return to map” accessibility element for dismissing the callout view and restoring focus to the annotation on the map.
Assigned unique IDs to localizable English strings in code.
Made iosapp non-localizable. For the time being, it isn’t worth the trouble to localize more strings for this demo application than for the SDK itself.
Made storyboards and strings throughout the SDK and iosapp localizable. Replaced the compass image with an unlabeled image. Draw a localizable string atop it at runtime.
Redefined NSLocalizedString() and NSLocalizedStringFromTable() macros to look at the SDK bundle rather than the main application bundle. This redefinition has no effect on the host application, because it’s in an internal header. That header must be included in all files that contain localizable strings. See NSBundle+MGLAdditions.h for a full explanation.
Added a make rule that runs genstrings and ensures UTF-8 output (since genstrings insists on UTF-16).
Use MGLCoordinateFormatter in iosapp for dropped pin callouts. Rely on subclasses of MGLPointAnnotation instead of annotation titles to distinguish between different kinds of point annotations.
Added a degree-minute-second coordinate formatter for general use. Use this formatter in iosapp and osxapp.
Added unit tests for the coordinate formatter and for round-tripping geometry types through NSValue.
Fixed a race condition in which the access token alert controller would fail to present because the view controller hadn’t yet entered the view hierarchy, plus a downstream crash caused by the access token being missing.
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.
