The final frame is self-destructing – it destroys the frame and finish functions – so technically we’re no longer inTransition(). Yet there still needs to be an update after that final frame.
Also, avoid a redundant change notification on the last frame. (It would come too late, after the DidChange notification, anyhow.)
Fixes#2946.
Moved mbgl::util::default_styles to a more appropriate location, where iOS platform code can also find it. Moved -[MGLMapView bundledStyleURLs] (which is now deprecated) and the style switcher in iosapp to default_styles.
Added a collection of convenience methods for getting style URLs. It makes little sense to layer an enum atop this, as MapKit does, because MGLMapView styles aren’t limited to this set. A good analogy is UIColor. This also makes for a good entry point for future runtime styling APIs.
Introduced independent constants for each default style, because it’s more common to need access to a particular style than to iterate over them. This fact is apparent in the MGLStyle class, which now uses macros and assertions to ensure that it’s kept up-to-date with changes in default_styles.
/ref #1462
The new styleURL__ inspectable property is carefully named to masquerade as a URL property in Interface Builder, even though IB supports no such thing.
If the user enters an invalid URL into the “Style URL” inspectable, throw an error instead of silently setting the style to the default. This check is not required in -setStyleURL:, which takes a real NSURL.
Cellular carrier name and connectivity level will now only be sent if
the developer independently chooses to link the CoreTelephony framework
in their app.
