title: Problem with NSDate in NSUserDefaults
body: <p>I'm using NSUserDefaults and I have the code <code>mondayalarm = [prefs stringForKey:@"mondayalarm"];</code> and mondayalarm (first reference, not the key) is an NSDate. It's giving me the warning:</p>
  
  <blockquote>
    <p>incompatible Objective-C types assigning 'struct NSString *', expected 'struct NSDate *'</p>
  </blockquote>
  
  <p>How can i make it accept this without the warning?</p>
