iOS: Please add MGLUserTrackingModeFollowWithCourse

It looks like the follow user with heading is off by about 5 to 10 degrees. In this case the user was driving down W Olympic Blvd, but map orientation was quite a bit off. Maybe magnetic heading is being used instead?

Just to clarify this a bit...it seems to be orienting to the orientation of the phone, not the direction of travel. This seems very odd when you use it.

The 5 to 10 degrees was just the effect of holding the phone a slight angle from the direction of travel.

It would seem direction of travel is what is needed here more than the compass direction of the phone.

Sorry to keep going on and on, but it looks like this is the difference between using the newHeading from didUpdateHeading: and newLocation.course from the didUpdateToLocation: delegate methods of CLLocationManager.

For navigation apps, the course is what is needed. Maybe another user tracking mode is needed?

We have hacked in a FollowUserWithCourse option. But really look forward to a proper solution with smooth animation and all that jazz! Notice how the user location is not always the center of the map?

Smooth animation is covered by #1582.

Thanks, but I did want to differentiate between "follow user with heading" which is the magnetic direction, and "follow user with course" which is their direction of travel. Navigation apps will need follow with course.

Understood, I left this issue open to track that request.
