title: Save a value of a local variable
body: <p>How can I save a value of a variable in objective-c, for example a <code>BOOL</code>, and when I return for the app the value of my variable is the last value setted?! For exemple:</p>
  
  <pre><code>BOOL *firstAccess;
  
  firstAccess = TRUE;
  </code></pre>
  
  <p>I finish the app and return, and i wished that my variable were <code>TRUE</code>, again.</p>
  
  <p>Thanks</p>
