    1. You need to retain an objects so that it won’t get deallocated while you’re using it.
    2. The higher the retain count, the more times a retain message has been sent to an object.
    3. If you declare the property correctly, assigning values to it will handle the memory management for that instance variable correctly. That might mean calling retain or release correctly for object types.

    It sure sounds like you need to read some of the documentation. Perhaps specifically the Memory Management Programming Guide?
