/**
Reasons describing why a camera move occurred.
Values of this type are passed to the `MGLMapView`'s delegate in the following methods:
- `-mapView:shouldChangeFromCamera:toCamera:reason:`
- `-mapView:regionWillChangeWithReason:animated:`
- `-mapView:regionIsChangingWithReason:`
- `-mapView:regionDidChangeWithReason:animated:`
It's important to note that it's almost impossible to perform a rotate without zooming (in or out),
so when you want to check for a pan vs a rotation, it's important to ensure you check
MGLCameraChangeReasonGesturePan against MGLCameraChangeReasonGestureRotateAndZoom.
*/
typedef NS_ENUM(NSUInteger, MGLCameraChangeReason)
{
/// The reason for the camera change is invalid. This is considered an error.
MGLCameraChangeReasonInvalid,
/// Set when a public API that moves the camera is called.
MGLCameraChangeReasonProgrammatic,
/// The user panned the map.
MGLCameraChangeReasonGesturePan,
/// The user rotated the map. This is also used when the user resets the map orientation by tapping
/// on the compass. Note that since it's almost impossible to rotate without zooming, you should
/// also check against MGLCameraChangeReasonGestureRotateAndZoom
MGLCameraChangeReasonGestureRotate,
/// The user zoomed the map. This is used when pinching the map, double tapping and for the one
/// finger drag zoom gesture.
MGLCameraChangeReasonGestureZoom,
/// The user panned and rotated the map, without lifting their fingers.
MGLCameraChangeReasonGesturePanAndRotate,
/// The user rotated and zoomed the map. You will see this value when rotating the map without a
/// deliberate zoom. See also MGLCameraChangeReasonGestureRotate.
