Detailed Description

Propagates NSAppDelegate callbacks to registered delegates.

Method Documentation

addDelegate:

- (void) addDelegate:

(NSObject<FlutterAppLifecycleDelegate>*)

delegate

Registers delegate to receive lifecycle callbacks via this FlutterAppLifecycleDelegate as long as it is alive.

delegate will only be referenced weakly.

Definition at line 76 of file FlutterAppLifecycleDelegate.mm.

                   :(NSObject<FlutterAppLifecycleDelegate>*)delegate {
  [_delegates addPointer:(__bridge void*)delegate];
  if (IsPowerOfTwo([_delegates count])) {
    [_delegates compact];
  }
}

removeDelegate:

- (void) removeDelegate:

(NSObject<FlutterAppLifecycleDelegate>*)

delegate

Unregisters delegate so that it will no longer receive life cycle callbacks via this FlutterAppLifecycleDelegate.

delegate will only be referenced weakly.

Definition at line 83 of file FlutterAppLifecycleDelegate.mm.

                      :(NSObject<FlutterAppLifecycleDelegate>*)delegate {
  NSUInteger index = [[_delegates allObjects] indexOfObject:delegate];
  if (index != NSNotFound) {
    [_delegates removePointerAtIndex:index];
  }
}
