Hey, per OSX app-store regulations would an app be approved if it loads a flash
player inside a uiwebview but does not show that view, instead expanding on the
callbacks from it and creating a new experience and adding new functionality to
that service!?

Never mind. You clearly did
Now that my brain cell's caffeine levels are normalizing, I seem to recall
somewhere in the Cocoa docs stating that starting a method name with a string

Yeah, it must have been in the ARC docs. I remember that using init or new are
not good ideas.

Clang objected to a variable that started with "new" when we turned it into a
property, because then there was a method named "new" that wasn't doing what it
expected. I don't remember the details; I renamed it a long time ago.

This is normal. I think the idea is that the user gets a cue that whatever

while the action is carried out.

That's totally untrue. When an item is chosen, the
Don't delay the action/target part, write a wrapper function and delay that:
