iOS：检查手机是否已锁定 [英] iOS: Check if the Phone is Locked

问题描述

有没有办法检查手机是否已锁定？或者我是否收到手机将被锁定的通知？

Is there a way to check if the phone is locked? Or do I receive a notification of the phone is going to be locked?

我的应用程序在后台运行，继续播放音频，所以applicationWillResignActive：是不是真的就是我要找

My app runs in the background, continues to play audio, so applicationWillResignActive: isn't really what I am looking for.

推荐答案

你不能，直接。间接的，你可以看为加速度计的开/关通知的。

You can't, directly. Indirectly, you can watch for accelerometer on/off notifications.

为什么你想首先检测这个事件？

Why do you want to detect this event in the first place?
