• GMSIndoorDisplay allows observation and control of indoor level data display, usable only on the main thread.

• It provides access to the currently focused building (activeBuilding) and its active level (activeLevel).

• The activeLevel property can be manipulated to change the displayed level or hide the building while keeping it active.

• A delegate (delegate) can be assigned to receive updates and events related to indoor display changes.

  Objective-C

  @property (nonatomic, readonly, nullable) GMSIndoorBuilding *activeBuilding;

• activeLevel

  Provides and controls the active level for activeBuilding. Will be updated whenever activeBuilding changes, and may be set to any member of activeBuilding’s levels property. May also be set to nil if the building is underground, to stop showing the building (the building will remain active).
