我对此没有任何证据，但这将涉及修改"UserExperience"，这是 Apple不允许的 strong>(以及为什么还有很多人越狱他们的电话).

I don't have any evidence for that, but this would involve modifying the "UserExperience" - which is something that Apple never would allow (and why still many people jailbreak their phones).

这涉及到关闭电源"以及静音"-因为两者都可能破坏UX(您等待一个重要的呼叫，但是应用程序X破坏了声音).

And this involves "power off" as well as "mute sound" - because both could destroy the UX (you wait for an important call, but application X broke the sound).
