Hello,
This code is given in the "Transitioning to ARC Release Notes" as an
example of accomodating blocks in an ARC environment:
__block MyViewController *myController = [[MyViewController alloc]
init…];
// ...
myController.completionHandler = ^(NSInteger result) {
[myController dismissViewControllerAnimated:YES completion:nil];
myController = nil;
};
Supposedly this avoids a retain cycle. But where is the cycle? At
least two objects are needed for a cycle. What is the second one?
Excuse me if I'm being dumb.
Jan E.
