IOS8 中的错误“沙盒拒绝 iokit-get-properties”

Question

当我在我正在编程的应用程序上调试我的 iPad 时，我有一个奇怪的行为，我很确定只有在将所有生产版本更新到 iOS8 后才会出现这种情况。

我正在使用 Multipeer Connectivity，并尝试调试随机断开连接，我最终看到设备的控制台很长。我注意到在断开连接之前或之后总是有一堆（我的意思是从两打到几百行）。

另外，我的应用程序使用后台服务，我不知道它是否相关，但这需要我编辑应用程序的配置（在 Xcode 中）以启用它以及更新我的证书。

那么，为什么会出现这些“Sandbox deny iokit-get-properties”消息？

谢谢。

除非您尝试从应用访问受限的 IOKit 属性，否则不应发生这种情况。 iOS 上的沙箱并没有完全阻止 IOKit 和 IO Registry，但看起来 Apple 已经选择了应该拒绝的特定节点和值。您在此处看到的是被拒绝的值，但其他值可能正在通过。

如果您没有直接使用 IOKit 做任何事情，那么这实际上可能是进行这些调用的 Multipeer Connectivity 框架，在这种情况下，这个问题现在可能已经解决了。
