Disable home button without rebooting device

Question

I want that after installing my app from an OTA the home button of the device will not work at all so that user is unable to come out from the App. My digging led me to foll

Answer 1

If you are able to jailbreak your device create a LaunchDaemon or use an existing one. The LaunchDaemon is a file in plist format that is called upon rebooting and starting your device. You will also need a file named open created by K3A

Download open from here

You will need to move open to /usr/bin/ or you can put it inside your app does not matter but set permissions to 0755 and root:wheel

Now on to the LaunchDaemons, they are stored here

/System/Library/LaunchDaemons

Here is an example. Lets say you name the LaunchDaemon

com.gauravstomar.test.plist

Where it says com.bundle.identifier put your apps identifier you may also find it in your Info.plist inside of your apps directory where it says CFBundleIdentifier

Now inside the plist insert the following information

    Label
    com.gauravstomar.test
    ProgramArguments
        
          open
          com.bundle.identifier
        
    RunAtLoad
    
        StartInterval
        1

Label has to be the same name as the LaunchDaemon.plist excluding plist extension

ProgramArguments is what calls the file open and launches the app

RunAtLoad makes this plist launch upon reboot

StartInterval will make the LaunchDaemon.plist open back up after 1 second if the user exits the app, if the user is still in the app nothing will happened

Make sure the permissions for your LaunchDaemon is set to

0644 root:wheel

You can still use your mobileconfig so that the home button is disabled. Once assessment is complete you can disable the LaunchDaemon so that the app stops relaunching itself with the following command launchctl unload/System/Library/LaunchDaemon/com.gauravstomar.plist

Let me know if you need any more help.
