To prevent guests from closing LumaBooth and accessing other apps on the iPad, you'll need to setup Guided Access which locks LumaBooth to be the only available application.
Setup Guided Access
Tap Settings > General > Accessibility > Guided Access to set up Guided Access.
From there you can:
- Set Guided Access to On
- Set a passcode that controls the use of Guided Access and prevents someone from exiting the application.
Set whether the device can go to sleep during a session.
Set Mirror Display Auto-Lock to On (iOS 12 and above only).
Start a Guided Access session
- Open LumaBooth.
- iPads with home button: Triple-click the Home button.
- iPads with no home button: Triple press the power button.
- Adjust settings for the session, then click Start.
End Guided Access
- To end guided access, triple click the home button or triple press the power button same as before and enter in the PIN you setup up under Guided Access.
In iOS 9 and later the default settings are configured so that the auto-lock time no longer applies when used in Guided Access. This means the device will remain active and can continually drain the battery even when an auto-lock time has been set.
However, there is an adjustment you can make which will help to avoid unwanted battery drain while using Guided Access. Within the Guided Access settings if you turn ON the sleep/wake button option the device will sleep after a period of time and in addition, you can use the device lock button to lock the device immediately.
To make this adjustment, open Guided Access by triple pressing the home button. Tap options under the hardware buttons heading then switch the sleep/wake button to on.
This setting is specific to each app used while in Guided Access, so the change will need to made when you enter Guided Access for each individual app.
