How are you creating the array? The retain count not changing when you add it to the array seems to indicate that you aren't using array callbacks that retain stuff added to the array. Other than that the retain count sequences seem reasonable.

I was passing NULL as the in CFArrayCreateMutable and presume that the default behaviour was to retain the string when I append it to the array. After reviewing the documentation again, I realize that I should have passed kCFTypeArrayCallBacks instead so it would treat all objects appended as CF objects. Changing that solved my problem, and the retain count looks correct now as well! I guess I got confused with the observation that CFStringCreateCopy seemed to work while the others did not.

I was scratching my head for days over this!

Thanks!
