Question

I have an object that encapsulates an asynchronous NSURL request. When should I release it?

StrangersRequest *request = [[StrangersRequest alloc] init];
request.strangersListener = strangersListener;
[request send];

Analyze in XCode says I should release it immediately – but that’s not right because it has to handle the URLRequest callback.

What’s an appropriate pattern for releasing objects that handle asynchronous events?

I’m guessing I should release when the request completes (connectionDidFinishLoading). If so, how can I stop Analyze from complaining about it?

Answer 1

You could follow the NSThread model and have the object retain itself until its asynchronous task has completed.
