title: Cancel button on MFMessageComposeViewController does not show up
body: <p>In my iPhone application, I have just implemented in-app SMS functionality. SMS functionality is working fine. But after opening MFMessageComposeViewController, if user wants to cancel sending sms, they have no option. The only option left is to send an sms, then only return on previous view. There should be a cancel button on navigation bar just as it is in the email composer. Below is the line of code that I wrote to have in-app sms functionality:</p>
  
  <pre><code>-(void) smsComposer{
       MFMessageComposeViewController *_smsCompose = [[MFMessageComposeViewController alloc] init];
       if ([MFMessageComposeViewController canSendText]) {
           _smsCompose.body = @"SMS BODY";
           _smsCompose.messageComposeDelegate = self;
           [self presentModalViewController:_smsCompose animated:YES];
      }
  }
  </code></pre>
  
  <p>Is there anything that I am missing?</p>
  
  <p>Thanks in advance,
  PC</p>
