Refactored MGLUserLocationAnnotationView (redux) #5882

friedbunny · 2016-08-06T00:34:09Z

This is a replacement PR for #5573 that targets master.

Additionally, I’ve rewritten #5816 so that the hit testing layer can be set by any subclass of MGLUserLocationAnnotationView.

platform/ios/src/MGLMapView.mm

+
+        CGPoint tapPointForUserLocation = self.userLocationAnnotationView.hitTestLayer.superlayer ? [singleTap locationInView:self.userLocationAnnotationView] : tapPoint;
+
+        CALayer *hitLayer = self.userLocationVisible ? [self.userLocationAnnotationView.hitTestLayer hitTest:tapPointForUserLocation] : nil;


This doesn’t need to check again for self.userLocationVisible — will remove.

Saw some weird behavior just now that I don’t have time to investigate, but the user dot wasn’t being updated/deselected when another annotation became selected. E.g., tapping another annotation while in course tracking mode would leave the puck on screen until the tracking mode was manually changed again.

Will investigate next week.

Rebased again after v3.3.4 was merged back to master, which included a backport of 7aec17d in #5894.

380d54a9d5106fb957455c4376e086634ff05f39 fixes the issue where the annotation was not updating immediately.

The didUpdateUserLocation: method has been changed to update, which is again called from -[MGLMapView updateUserLocationAnnotationViewAnimatedWithDuration:].

A separate method that’s called when the user’s location changes shouldn’t be necessary, as the existing userLocation property will already contain this information.

The user location annotation needs updates more frequently than once per location event — it needs to respond to user interaction, viewport changes, and user tracking mode changes.

Very open to naming suggestions for update.

friedbunny · 2016-08-13T02:44:18Z

Updated the docs a bit. Is the @warning too much?

1ec5 · 2016-08-13T03:06:47Z

platform/ios/src/MGLUserLocationAnnotationView.h

+ user interaction, a change in the user’s location, when the user tracking mode
+ changes, or when the viewport changes.
+
+ @warning During user interaction with the map, this method may be called many


No keyword is needed here, although @note is fine if you think it’s sufficiently important. @warning should be reserved for pitfalls that may lead to data loss or similarly catastrophic outcomes.

The didUpdateUserLocation: method has been changed to update, which is again called from -[MGLMapView updateUserLocationAnnotationViewAnimatedWithDuration:].

Can you say more about this @friedbunny? didUpdateUserLocation: is akin to how MapKit does things.

friedbunny · 2016-08-15T18:36:15Z

Can you say more about this @friedbunny? didUpdateUserLocation: is akin to how MapKit does things.

@frederoni added -[MGLUserLocationAnnotationView didUpdateUserLocation:], which became the sole way the user location annotation was updated with the removal of [annotationView setupLayers] from -[MGLMapView updateUserLocationAnnotationViewAnimatedWithDuration:] in 91ec7cb#diff-20502b6bc02986a4398d0da84b2d4b94L4683.

I renamed -[MGLUserLocationAnnotationView didUpdateUserLocation:] to -[MGLUserLocationAnnotationView update] and removed its MGLUserLocation value, because this is already always available via MGLUserLocationAnnotationView.userLocation.

I then re-added the call to -[MGLUserLocationAnnotationView update] (changed from a direct call to -setupLayers previously) in -[MGLMapView updateUserLocationAnnotationViewAnimatedWithDuration:], so that the user location annotation can update when the user interacts with the map, when the tracking mode changes, etc.

-[MGLMapViewDelegate mapView:didUpdateUserLocation:] is unchanged.

incanus · 2016-08-15T18:41:58Z

Aha! Thank you.

friedbunny · 2016-08-15T18:49:54Z

This is ready for review 👓 again — thanks y’all.

I should note: this is a fairly pure refactor. The main part that has changed versus v3.3.x is that MGLUserLocationAnnotationView is now available. The functionality of the existing dot/puck now lives in MGLFaux3DUserLocationAnnotationView and is unchanged.

…tionView

And implement this property in MGLFaux3DUserLocationAnnotationView. Generic reimplementation of #5816.

The user location annotation needs to change in response to many factors, not just user location updates. When the user tracking mode changes and when the viewport changes, the dot should respond immediately.

Also remove unnecessary header import.

Because, really, what choice do you have? <3 Xcode.
