UnobstructedArea ​

Functions ​

void unobstructed_area_service_subscribe(UnobstructedAreaHandlers handlers, void *context)

Subscribe to be notified when the app's unobstructed area changes. When an unobstructed area begins changing, the will_change handler will be called, and every will_change call is always paired with a did_change call that occurs when it is done changing given that the will_change and did_change handlers are set. When subscribing while the unobstructed area is changing, the will_change handler will be called after subscription in the next event loop.

Parameters ​
  • handlers: The handlers that should be called when the unobstructed area changes.
  • context: A user-provided context that will be passed to the callback handlers.

void unobstructed_area_service_unsubscribe(void)

Unsubscribe from notifications about changes to the app's unobstructed area.
