Problems with SBStoreDemoAppLock on iPad

Question

I'm trying to implement a kiosk mode on some iPads.

I came across this excellent post Lock-down iPhone/iPod/iPad so it can only run one app but have run into some problems running it on my iPad 2 with 7.0.4 installed on it.

I have tried using the linked sample http://ipadhire.co.nz/lockdown.mobileconfig as well as rolling my own, but constantly have issues. However, they appear to work just fine on the iOS Simulator which is running 7.0.3.

The Console output is as follows :

Anyone have any suggestions of what I should look at to fix the problem? I do realize there are other ways to do kiosks, but this mode fits my needs the best.

Answer 1

Unfortunately this doesn't seem possible on any physical device iOS 7+ in my testing. Apple looks to have specifically quashed this to force people to use the app lock setting which requires the devices to be supervised by a Configurator.

I've had some success using MDM solutions (AirWatch or Meraki) to force single app mode without actually requiring the devices to be physically plugged into the supervising Mac daily. You still have to setup supervision one time to allow the single app requirement to be pushed down from MDM though.
