Well - the subView is really a "settings" view - so it can be called up at
any time. And of course the user can rotate the device around while it's
already being viewed. So I suppose I can call a method in my subview from

Hello,
NSAttributedString has proven to be unsafe in many ways for use on a
secondary thread in our own applications. We were trying to do much
the same thing, get the size of a string from it. But it turns out
(obviously in retrospect) that it needs to use the font/GUI systems to
do this
Yeah sounds like the exact same problem I'm having. The problems aren't
consistent at all, it just happens once every few thousand strings.
Is there any easy way to execute a portion of code on the main thread without
going through the mess of delegates and selectors?

Delegates have *nothing* to do with main thread execution. Selectors a bit
orthogonal, too.

Hi. I realize this is a basic Cocoa question, but now that I need to know, I
