How to validate, if some controls/settings are enabled on iOS and Android real device?

I am new to Appium world. I have been assigned a task, in which my iOS app renders the document in READ_ONLY format.
After rendering, It does not even allow user to take a screenshot. Neither it allows to cut/copy the content of document.
How do I validate such settings (if screenshot is disabled OR after log tap on a document, Cut / Copy popup is not appearing) on iOS simulator or real device?
I am using Appium with Java.
