Restrict access to iOS built-in application

I'm interested in a way to restrict access to the build-in iOS applications(Settings,Calendar,Contacts,etc).

I've seen a lot of solutions but i don't want to jailbreak my devices.Also, the "Restrictions" setting isn't enought since it only blocks a few apps.

Could be 开发者_JAVA技巧anything from removing the icon or setting a passcode to access it.

Thanks,

You can set a passcode to access the device, but not for individual applications, and there's not built in way to hide icons that I'm aware of. Your only option is to jailbreak it or live with them not being restricted.
