Ah, yeah, that makes sense. But looking at the overall code now I'm not sure that it does. So, here's what actually happens at the [MKAsyncRequest facebookUsersGetInfo...] call:
+(void)facebookUsersGetInfo:(NSArray *)uids fields:(NSArray *)fields facebookConnection:(MKFacebook *)aFacebookConnection delegate:(id)aDelegate selector:(SEL)aSelector {
self = [[MKAsyncRequest alloc] initWithFacebookConnection:aFacebookConnection delegate:aDelegate selector:aSelector];
[NSURLConnection connectionWithRequest:[NSURLRequest requestWithURL:[aFacebookConnection facebookUsersGetInfoURL:uids fields:fields]] delegate:self];
}
seeing as the NSURLConnection method is asynchronous, releasing before it's done would be bad too.
Thoughts?
Paul
