Or: don’t resume the map until the application has entered the foreground.
UIApplicationWillEnterForegroundNotification is posted before UIApplicationDidBecomeActiveNotification, while the application is still in the background. That caused -createGLView to bail but did not cause the rest of -wakeGL: to bail. We would create the GLKView only after attempting to bind it (a no-op), resulting in a black view.
Fixes#1855.
Defer the creation of EAGLEContext and GLKView and the loading of OpenGL ES extensions. It is GLKView that drives the background crash, and Apple documentation specifically warns not to initialize an EAGLContext in the background. All the while, it should be safe for client code to avail itself of any public methods on MGLMapView.
Fixes#1460.
Rely on mbgl to drive compass rotation for simplicity. Eliminated fall-through from mbgl::MapChangeRegionIsChanging to mbgl::MapChangeRegionDidChange, because is-changing should not cause did-change to be fired.
Fixed a bug in which -[MGLMapView direction] could return 360 instead of 0. Switched to mbgl::util::wrap() for clarity. -updateCompass now relies on -direction to avoid code duplication.
In #1793, I conflated the compass container’s constraints to its parent view with the compass container’s content size constraints, but only in the iOS 7 code path. The result was a crash on launch due to an unprepared view hierarchy.
Fixes#1818.
Instead of transforming between return value and callback, pass
the wrapped callback on to the invoked function as the last argument.
This eliminates the need for multiple invokeWithArgument overloads
and permits invoked functions to be asynchronous.
Whoever determined the boundaries of the District of Columbia did not have fit-to-bounds implementations in mind. With this change, shapes that are not unrotated rectangles fit much, much better.
Also, on iOS 8.0+, use `+[NSLayoutConstraint activateConstraints:]` and `+deactivateConstraints:` to efficiently prevent redundant constraints from lingering.
Fixes#1779.
Added a bunch of functions to work with MGLCoordinateBounds in a separate header analogous to MKGeometry.h. Added resolution-independent tests for common fit to bounds scenarios.
Each side of the bounding box is specified independently, allowing more flexibility than the offset + padding construct supported in mapbox/mapbox-gl-js’ Camera.
The new implementation is now public and takes advantage of MGLCoordinateBounds. It is re-ported from `Camera.prototype.fitBounds()` in mapbox/mapbox-gl-js to ensure correct behavior. A new function, MGLCoordinateBoundsMake(), makes it easier to create an MGLCoordinateBounds for use with this method.
Listening to both `locationManager:didChangeAuthorizationStatus:` and `locationManager:didFailWithError:` delegate methods is unnecessary. Setting `showsUserLocation = NO` in the first means that the second never gets called and our `mapView:didFailToLocateUserWithError:` delegate method never gets called.
mbgl::Thread will keep a ThreadContext for each running instance
in a thread_local so we don't need to lookup a man in the Environment
every time we need some info about the current thread.
This patch is moving the ::currentlyOn check used on Debug build from
the Environment class to the ThreadContext.
Errors caused by client code should be communicated through NSExceptions. NSAsserts are intended for internal usage; because they include helpful information like the absolute path to the file containing the assertion, stripping the build (#1650) also strips assertion messages. Also replaced hardcoded references to methods in these messages with __PRETTY_FUNCTION__, which avoids future copy-pasta and handles cases in which the MGL class has been subclassed.
If no access token is set in the Info.plist, avoid triggering a KVO notification about the access token changing. By the same token (heh), avoid pulling a C string out of the change dictionary if the access token is being nilled out.
Added lightweight generics annotations to collection-typed method and protocol signatures to streamline usage of these members in Swift. Lightweight generic type specifiers are wrapped in conditionally-compiled macros for compatibility with Xcode 6.x.
Manually preprocess the NS_*_OF() macros in a temporary copy of each header before appledoc sees the headers. Also removed the --ignore flag because we no longer have a private headers folder under include/mbgl/ios/.
