Reply to a mail using gmail api ios
<p>I am working on a Mailbox app I am trying to reply to a mail.</p>

<p>I had gone through the documentations.</p>

<pre><code> GTLQueryGmail *query = [GTLQueryGmail queryForUsersMessagesSendWithUploadParameters:nil];
query.message = gtlGmailMessage; //parent message
[self.service executeQuery:query
                  delegate:self
         didFinishSelector:@selector(displayResult:finishedWithObject:error:)];
</code></pre>

<p>I need to know what all changes I need to do in the gtlGmailMessage to reply to the parent mail.</p>

<p>Thanks in Advance.</p>
