I’m doing some archiving to a property list and when I unarchive my data

  • 0

I’m doing some archiving to a property list and when I unarchive my data using NSKeyedUnarchiver I find that my app crashes if I release the object afterward. I was wondering if the finishDecoding message also autoreleases the object. Seems weird that it crashes when I release it.

    What do you release? NSKeyedUnarchiver or unarchived object?

    Should you release NSKeyedUnarchiver or not depends on how you created it. It follows usual rules. If you use alloc + initForReadingWithData you should release, if you use unarchiveObjectWithData or unarchiveObjectWithFile – you shouldn’t.

    Regarding result of decodeObjectForKey, it also follows usual rule that method returns autoreleased object and you shouldn’t release it unless you explicitly retained it.

    Regarding finishDecoding: you are expected to explicitly call it before NSKeyedUnarchiver object is released. You shouldn’t use unarchiver after that point, but object is still alive.
