In an app I'm thinking of writing I have a table view where each row

in order to work out what goes in the row (probably take about 2
seconds for each file). Obviously this is way too slow, so for the
rows that haven't been loaded yet I'm just going to display the name
of the file.
Idealy, when the file for a row hasn't been loaded yet, I'd like that
row to be displayed in grey rather than black.
You can use an NSAttributedString instead of an NSString as the row
value, and then specify styles or other colors as you see fit. You
may want to use key-value-coding for this and just write a fake
accessor for the name, which calls the real one and wraps it in an
attributed string as desired.
