title: App Rejected due to Mail
body: <p>My App got rejected and reason is below:-</p>
  
  <pre><code>Did not integrate with iOS features. For example, the email button should enable users to compose emails in the app rather than launching the Mail app.
  </code></pre>
  
  <p>I did not get that what they want. I have used <code>MFMailComposer</code> class so what's wrong with it?Any Suggestion.</p>
