UIWebView delegate being overreleased

[nicked]

I have a custom view controller (WebViewController) that contains a UIWebView, and which is also the delegate of that web view.

Note that while I am using BlocksKit in this project, this UIWebView does not use any BlocksKit extensions.

When the WebViewController is dismissed, regardless of whether the URL had finished loading or not, I get:

*** -[WebViewController release]: message sent to deallocated instance

from AutoreleasePoolPage::pop.

Also note that my project is using ARC, so at no point am I manually releasing anything.

In the dealloc method of my WebViewController, I am setting the UIWebView's delegate to nil, so that shouldn't be causing any problems.

When I exclude UIWebView+BlocksKit.m from the project, everything works fine.

Sorry I don't know how to debug this any better, let me know if there's anything I can try to get you more info.

Cheers,
Nick

+1.

I think when you set the UIWebView's delegate to nil, the "realDelegate" internal to blockskit is now pointing to a possibly deallocated object.

But whenever you set the realDelegate (BlocksKit does this automatically for you when you call the normal delegate setter), we attach a block to the real delegate that nils out our reference when it gets deallocated. However, we retain/autorelease whenever getting the real delegate to prevent it from unexpectedly disappearing. I think that might be the cause. We'll investigate alternate methods. Thanks for reporting this.

We have a fix in our next branch, pending some investigation. Don't want to make it worse than before. ;-) Should be out shortly.

EDIT: Fixed in 1.0.5. Cheers.
