title: How to share image to instagram within app in iOS?
body: <p>I have seen many questions related to my question and also got answer that there is no public api to share image to instagram within app. but my problem is that if i am opening instagram app from my app then there is no way to return back to my app and i also want to get username of logged in user before sharing image to instagram but can't get because as per my knowledge can't transfer data from one aap to another.  </p>
