-// "You take ownership of an object if you create it using a method whose name
-//  begins with "alloc" or "new" or contains "copy" (for example, alloc,
-//  newObject, or mutableCopy), or if you send it a retain message. You are
-//  responsible for relinquishing ownership of objects you own using release
-//  or autorelease. Any other time you receive an object, you must
