Method Documentation

addDelegate:

- (void) addDelegate:

(NSObject<FlutterSceneLifeCycleDelegate>*)

delegate

Definition at line 36 of file FlutterSceneLifeCycle.mm.

                   :(NSObject<FlutterSceneLifeCycleDelegate>*)delegate {
  [_delegates addPointer:(__bridge void*)delegate];
 
  // NSPointerArray is clever and assumes that unless a mutation operation has occurred on it that
  // has set one of its values to nil, nothing could have changed and it can skip compaction.
  // That's reasonable behaviour on a regular NSPointerArray but not for a weakObjectPointerArray.
  // As a workaround, we mutate it first. See: http://www.openradar.me/15396578
  [_delegates addPointer:nil];
  [_delegates compact];
