You're right - I missed the autorelease.
The point stands though; you don't need to create the dictionary at
all, and doing so is just wasted CPU cycles. The
-executeAndReturnError: method will create a dictionary if one is
needed. That's why theError is passed by reference, so the method can
dereference it.
Discussion of this can be found at the URL below. It uses NSError
objects, but the general idea is the same:
