Here is a trick I saw somewhere else that might do what you need. On the other hand, i'm still learning cocoa myself so it may have drawbacks that I'm unaware of.
Create a private property (like internal_foo below) to handle memory. Then have a public property to do the other stuff. So users of the class access the property with "foo" and you get synthesized memory management with internal_foo.
