The debugging suggestions made so far in this thread are fine. But
really, the only debugging tool needed here is your mind. Developing
that tool is the quickest route to fixing bugs like this.
11.06.09 04:24:30 test[767] *** -[NSCFArray objectAtIndex:]: index
(0) beyond bounds (0)
11.06.09 04:24:30 test[767] *** Terminating app due to uncaught
exception 'NSRangeException', reason: '*** -[NSCFArray
objectAtIndex:]: index (0) beyond bounds (0)'
This is a huge hint as to what the trouble is. You may not see it at
the moment, but in time you will - if you learn how to think it
through. Right now, you're not really thinking about it (no offense
intended), you're just trying stuff, hoping something "fixes" it, and
when that doesn't work, posting requests for help without including
enough detail for anyone to help you. The trouble is not the bug in
your code (everyone creates bugs, and this one is easy) it's the bug
in your thinking about the bug.
So how can I find the array call that leads to this?
Cmd-Shift-F, type "objectAtIndex", make sure the search options popup
is set to "In Project," hit Return. In the resulting list, look at
each found occurrence of "objectAtIndex". Option-click on
"objectAtIndex" to bring up its docs. Re-read them. Re-read your code.
See see where you might be using objectAtIndex incorrectly.
If you don't see the problem with your usage of objectAtIndex, post
the code here so others can see it.
You've said your app is "pretty simple." Any occurrences of
objectAtIndex: were likely put there by you. Look at each one and
examine how you use it. Re-read the documentation for objectAtIndex
and consider if anything you do might be out of accord with the docs
you read.
If by chance you don't find any occurrences of objectAtIndex, look at
all your other usage of NSArray/CFArray and think about what might
happen if any of them happened to invoke objectAtIndex with the values
you pass. Could your values trigger any problems?
Failing that, look at every line you've written. Your program is small
and simple. Work out what will happen on each line as the program runs.
