title: How to populate OTP from user's message box to application directly in iPhone?
body: <p>I am working on an internet trading application with its mobile and iPhone applications available. With the recent market trend, we are working on including two-factor authentication. For that, we will be sending a one-time password as a sms on user's registered mobile number.</p>
  
  <p>Is there a way,that the OTP can get automatically populated into application from user's message box in iPhone? What algorithm should I use to make my app read user's message box?</p>
  
  <p>Thanks in advance:)</p>
