title: Correct Objective-C class naming method?
body: <p>how should I call a class for a timeline custom view? My project's prefix is <code>HM</code>.</p>
  
  <pre><code>HMTimelineView
  </code></pre>
  
  <p>or</p>
  
  <pre><code>HMTimeline
  </code></pre>
  
  <p>Shouldn't I name any view class with the suffix <code>View</code>? But why is it <code>NSButton</code> but <code>NSImage**View**</code>?</p>
