title: Filter the warning type in Xcode
body: <p>In my <code>project</code> in <code>Xcode</code>, my code always has many <code>warning</code>, and I think some is import and some is not that import for my <code>code</code>:</p>
  
  <p>Such as a type is :<code>xxx is deprecaetd in iOS 8.0 - Use xxx</code></p>
  
  <p>another type is: <code>Undeclared selector 'respondsToTapLike'</code></p>
  
  <p>or other more.</p>
  
  <p>There is so many type warning:</p>
  
  <blockquote>
    <p><a href="https://i.stack.imgur.com/mFVgt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mFVgt.png" alt="many type in proj"></a></p>
  </blockquote>
  
  <p>Now, how can I filter the <code>warning type</code> in <code>Buildtime</code>? </p>
  
  <p><code>eg</code>: I just want to show the type of <code>Method possibly missing a [super awakeFromNib] call</code>.</p>
  
  <p>If can filter the type, how to do?</p>
