I have looked several links and read the Apple Documentation but I don't get any step-wise instructions to mirror the content of app on an external device. All they explain is how to display a new window for an external screen if recognized.
In my app, I just need to display the current screen being shown in the app on an airplay enabled device. There is a airplay button, clicking on which will check for available external screens and display the content present on the device on that screen.
