title: Class variable memory lifecycle in objective-c
body: <p>If I declare a class variable in .m file (contrast to instance variable) and access it by a setter &amp; getter e.g. [MyClass setValue], [MyClass Value] </p>
  
  <p>When will this variable memory be allocated and when will it be freed? </p>
  
  <p>Just a new questions I thought of from a previous question: <a href="https://stackoverflow.com/questions/5826964/how-to-store-relatively-static-but-configurable-information">How to store relatively static but configurable information</a> </p>
