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
Thank you.
