If you're testing an iOS Prototype that is accessed via a browser, you can also choose whether to show the address bar and other browser controls.
To get rid of the header and footer:
Select 'iOS' under 'Device requirements' and select 'Controls hidden' under 'Browser Controls' when creating a 'Round' within a 'Project'.
If you've already created your 'Round' you can also click the 'Edit' button beside your 'Round' to change your 'Browser' control preferences.
This functionality is only available for iOS devices and will disable the address bar, back and forward buttons, etc.
For additional details on various aspects of prototyping please review our prototyping tools documentation.
