Force user to Set Passcode and Screen Timeout in iOS

Question

Targetting iOS 8 with Monotouch

When our app starts up on iOS I would like to check that the user has set a Passcode (at least) and a screen timeout of no more than 3 minutes.

If they have not I want to Force them to go to Settings and do so. Is this possible?

It is possible for Android apps with Admin permissions

Answer 1

Try this out :)

Once you've added the category you can check it like so:

- (void)checkPasscodeState
{
    LNPasscodeStatus status = [UIDevice currentDevice].passcodeStatus;
    switch (status) {
        case LNPasscodeStatusEnabled:
            // a passcode is set 
            break;

        case LNPasscodeStatusDisabled:
            // passcode is not set
            break;

        case LNPasscodeStatusUnknown:
        default:
            // error checking.. fallback somehow.
            break;
    }
}

Alternatively, if this is for an enterprise app and you have an MDM system, you could use a configuration profile to require that a passcode is set on the device.

Answer 2

To verify that the user has a passcode, you can attempt storing an item in the Keychain with kSecAttrAccessible set to kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly . Then you can verify that it exists and indirectly verify that the user has a passcode.

不，您目前无法获得有关密码和屏幕自动锁定延迟时间的信息。

Answer 4

We can achieve this only by MDM in ios device where we can directly enforce this. For Android as you said this could be achieved in may ways
