title: Where should I release static local and global variable with ARC?
body: <p>I just created a new class in my project, subclass of UITableViewController and noticed that in the method tableView:cellForRowAtIndexPath: template, Apple still provide a static local NSString to use as a cell identifier. </p>
  
  <p>I know that for static global/local variable we need to assign nil cause it's considered as strong.</p>
  
  <p>So I asked myself the question : Where should I assign nil to static global variable ?
  And static global variable ?</p>
  
  <p>Thanks for the answers guys</p>
