有没有一个简洁的方法来判断iPhone / iPad是否已被用户设置了密码

Question

I have asked this question long before.

I know it maybe impossible, but as far as I know, 'Find my friends' has this features and it works just so well, so I wonder if now there is a neat and legitimate way of doing that.

Answer 1

Just because Apple's Find My Friends app has a feature does not mean the API is publicly available. If this app is not an enterprise app, you can't use private APIs and have your app put on the app store. If it is an enterprise app, you may want to look into setting up a configuration profile for the device. In order to access the VPN for my employer, I had to install a configuration profile (visible in Settings) that requires a passcode to be entered every time I unlock my iPad. Without that, I cannot VPN into their intranet. TestFlight uses a similar approach with profiles to register a device to receive builds. I would check out this link from Apple on setting up these sorts of profiles for enterprise applications: http://www.apple.com/iphone/business/resources/

Answer 2

There's no way to detect this programmatically from within an iPhone SDK-based application. If you need to, you should file an enhancement request with Apple at http://bugreporter.apple.com
