title: subclassing issue with static constant variable in iOS
body: <p>I have Class A and Class B.</p>
  
  <p>Class B subclasses Class A
  Class A has a static constant NSString variable</p>
  
  <p>In a method of Class B I need to use the static constant NSString variable of Class A. What are my options ?</p>
  
  <p>I tried declaring the same thing again, but caused problem (internal inconsistency), tried without using (says, variable undeclared).</p>
  
  <p>Any idea how I can solve this problem ?</p>
  
  <p>Thanks.</p>
