Steve,
There are no web views. Because we're using a UITextView, it loads the WebKit
behind the scene (I guess to support links that could appear in the text in the
UITextView) and when that UITextView is deallocated from another thread than
the main thread or the webkit thread, it raises an ex
A UITableViewCell could be deallocated as soon as its row scrolls out of view.
UITableView will reuse cells if you specify a reuse identifier, but I don't
believe that the docs actually specify the number of cells that are reused.
I'm assuming that the web view is displayed when the user taps a
It seems that the deallocation happens when a block is being deallocated. Is it
possible that a block ran on the main queue of an NSOperationQueue could be
deallocated in another thread?

Hello Luke.
Well, I already checked that. The cell is being deallocated from a secondary
thread but there is nothing in the thread that indicates what triggered it. It
looks like a performSelector:withObject:afterDelay: or something like it but we
don't have any of those in the table view contr
Think about it simply. A cell gets deallocated just like any other object -
when its retain count goes to zero. If you're looking for a cell getting
deallocated on a non-main thread, you're looking for a place release is being
called on a non-main thread. I would think you could just override th

I recently posted a query on the Xcode-Users list but with no reply so far.
I hopes of accelerating some standard C functions, I've run a few timing
experiments to assess vForce.h function performance. The results are
disappointing.

Hello.
I'm trying to track a crash in our app where we have a custom UITableView cell
that contains a UITextView because we need the ability to display and open
links that might be in the text we're displaying in the text view.
The problem is that somehow, the cell is deallocated and WebKit com

No, you just use it directly. As Ken mentioned, any variable you
