Replaced std::map::operator[] usage with std::map::at(). Backed up an assertion on iOS with a guard when -annotationTagsInRect: returns the tag of a nonexistent annotation, for consistency with macOS. Removed an unnecessary and risky subscript into _annotationContextsByAnnotationTag in -positioningRectForCalloutForAnnotationWithTag: on iOS.
This silences a compatibility warning that was introduced in a previous
refactor that changed the return type of the callout view for
annotation delegate method. This also adds checks to ensure that the
callout view provided by the delegate to the map view is of the correct
type and conforms to the correct protocol.
Now that annotation classes override -isEqual:, it’s no longer appropriate to rely on -isEqual: or -containsObject: to check for the preexistence of an annotation. Those methods become deep equality tests, which have worse performance. Checking for identity allows the developer to add a polyline and polygon with identical coordinates, title, etc. to the map.
Implemented a missing -[MGLPolyline isEqual:].
Removed outdated comments about -annotationTagForAnnotation: being expensive.
Avoid canceling transitions (and triggering preexisting completion handlers) until we get a chance to ensure that a new transition really does have to begin. Consistently avoid mbgl transitions for redundant camera changes. Upon bailing, schedule the completion handler to run asynchronously on a delay equivalent to the requested animation duration.
Added a “functional” equality method to MGLMapCamera that avoids trivial differences.
Fixed invocations of XCTAssertEqualWithAccuracy() that incorrectly expressed the accuracy as a number of digits rather than a scalar tolerance.
Round double-tap and two-finger tap zoom gestures to the nearest integer zoom level. This has the benefits for raster tiles, as well as styles with zoom-based functions.
This results in a wider possible zoom range — ~0.5-1.5:
Old: z4.6 → z5.6 (+1.0), z4.4 → z5.4 (+1.0)
New: z4.6 → z6.0 (+1.4), z4.4 → z5.0 (+0.6)
* [ios, macos] Added delegate method to restrict movement
Added a way for the delegate to restrict where the user can move within the map using gestures.
Fixes#2457.
* [ios] Added support to restrict movement in pinch/rotate gestures
* [ios] Added support to restrict movement in double tap/quick zoom/two finger drag gestures
* [ios] fixed camera reset before two finger drag gesture is complete
* [ios] fixed camera comparison in double tap gestures
* [ios] Changelog update
* [macos] Changelog updated
* [ios, macos] Changelog cleanup
* [ios, macos] Added documentation to clarify performance impact
* [ios] clarified variable name
* [ios] blocking gestures implementation changed to a predictive approach
* [ios] gesture delegate methods refactoring
* [ios] Removed duplicated methods, improved code readability
* [ios] code refactoring to clarify the conditions to execute a gesture
* [ios, macos] Made MGLMapView.style property nullable
MGLMapView’s style property is now nullable (optional in Swift). The property is set to nil while the style loads and in the event that the style has failed to load.
* [ios, macos] Switch to delegate method
* [macos] Create MGLMapView programmatically for layer tests
When MGLMapView is created via a nib, -initWithCoder: is called, causing styleURL to be set to nil, in turn causing the default Streets style to be loaded, fooling MGLStyleLayerTests into thinking one-line has been loaded. Instead, create MGLMapView programmatically, passing the intended style URL into the initializer, preventing Streets from being loaded.
Views that are added outside of the viewport do not always have an
instantiated presentationLayer. Attempting to use a nil
presentationLayer to move a view offscreen resulted in the view
being pinned to the left side of the view port (at x == 0).
Fix a bug where an annotation view variable was incorrectly
re-declared which caused annotation views to not appear
in some cases. This also refactors the guard that spot
checks that annotation view are or are not visible.
* [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.
* [ios, macos] Replaced custom style layer API with MGLOpenGLStyleLayer
Replaced the custom style layer API on MGLMapView with an equally unsupported MGLOpenGLStyleLayer API that nonetheless is consistent with the broader runtime styling API and is compatible with macOS.
Fixed an unrecognized selector crash when wrapping a layer of unrecognized type coming from mbgl.
* [macos] Added lime green layer demo to macosapp
Reprised the demo removed from iosapp in #5091.
* [ios, macos] Rationalized MGLOpenGLStyleLayer API
MGLStyle now strongly references any MGLOpenGLStyleLayer object that’s added to it, in order to prevent pointers from going stale and make it easy for layer drawing code to get more information about the map view. Replaced the MGLOpenGLStyleLayer callback blocks with overridable instance methods. Added internal documentation for each method. Subclassed MGLOpenGLStyleLayer as LimeGreenStyleLayer inside macosapp.
Consolidated -addToMapView: into -addToMapView:belowLayer: to ensure that MGLRedundantLayerException gets raised even if the layer is being inserted rather than added to the bottom of the stack.
* [core] Clarified that rendering happens on the main thread
* [ios, macos] Fixed removing and re-adding MGLOpenGLStyleLayer
Don’t allow index-based layer removal to circumvent -removeFromMapView:, which MGLOpenGLStyleLayer relies on to synchronize the style’s array of MGLOpenGLStyleLayers. When obtaining an MGLOpenGLStyleLayer, get the instance already added to the style instead of creating a new one to wrap the underlying CustomLayer.
* Make tap gesture recognizer fail if it doesn’t do anything.
* fix typo
* Use the right nullable
* update changelog
* Make single click gesture recognizer fail if it doesn’t select an annotation
* fix changelog typo
* Remove singleTapGestureRecognizer from public header
This adds a ref count to guard against calling activate after it has
already been called. This can happen when a layer is added during
certain map lifecycle methods like MapChangeWillStartRenderingFrame
that also triggers activation. This also protects against issues
related to a deactivation of the context happening in an inner scope
while an outer scope is still expecting to be able to use the context.
Replaced -[MGLMapView style] with a property. Keep the MGLStyle object around for the lifetime of the style.
Bracket changes to layers in willChange and didChange calls. The built-in point annotation layer is added after the style is finished loading but before the map is finished loading. Cause a second wave of change notifications to go out, about both sources and layers. Issue change notifications for style layers when shape annotations are added or removed.
