Further to earlier answers, it’s worth pointing out you’ve got an anti-pattern
in this code. You go:
1. Check if file exists
2. Try to read file
There is no point to step 1. Just do step 2 directly, and handle failure there.
If you _don’t_ handle failure at step 2, you’ve got yourself a nasty little
bug/race condition, so it needs to be done anyhow.
Furthermore, use more modern APIs for reading from disk and you’ll get back an
NSError object in the event of failure, which can be used to tell the user or
console more information on _why_ the op failed.
e.g.
+dataWithContentsOfURL:options:error:
+propertyListWithData:options:format:error:
