I'm trying to make sure that this part of my code is good and clean and not
leaking. I believe that I have it right (but still think I have something
wrong).
This code makes a list of file paths, and then copies the files or folders from
their location to the destination the user selected. If the item already exists
in the destination, I delete it first (to overwrite with new data, yes this is
what I intend and the user is aware of how the app works).
I've read all your previous responses (Thanks) and it seems like since I am
just using "normal" strings that they will be autoreleased on their own. There
are now no compiler cautions and the app seems to work OK.
A side issue is that I want to add a 2 second delay before closing the sheet
that is displayed, is NSTimer the correct item to use?
