iOS 9 : Add Action When Push “Back To App” Button

Question

I've created 2 app. The first app can send value to the second app to process (URL Scheme). After success in the second app, it can open the first app and give a response using UIButton. but how to detect "back to app" is pressed so I can add action to give response to the first app?

Is there any delegate at "back to app" button? I want to show alert before "back to app" start switching app to previous app.

Answer 1

The thing you are asking for is not possible. Users, not apps, are supposed to be in control of which app is in the foreground.
