You can detect the change by registering for the notification
_UIClassicApplicationWillChangeZoomNotificationNameand then handle the scale change using more or less the method outlined by @magma in his answer._UIClassicApplicationWillChangeZoomNotificationNamewill tell you when the “2x”/”1x” button has been used to change the scale.
