title: Obj-C: [NSString stringWithString:@"string"] vs. @"string"
body: <p>I've seen people do something like <code>[NSString stringWithString:@"some string"]</code>. Why not just do <code>@"some string"</code>?</p>
  
  <p>For an example, look at the <a href="https://github.com/facebook/facebook-ios-sdk/blob/master/src/FBRequest.m#L147" rel="nofollow noreferrer"><code>facebook-ios-sdk</code></a>.</p>
  
  <p><a href="https://stackoverflow.com/questions/1616348/nsstring-stringwithstring-whats-the-point">+[NSString stringWithString:] -- what&#39;s the point?</a> is a similar question, but none of the answers address <code>[NSString stringWithString:@"some string"]</code> vs. <code>@"some string"</code>.</p>
