ios - 什么是 iOS 7 中的 AppleBasebandManager 框架？

Question

In iOS there are two kinds of frameworks: public frameworks and private frameworks. Public frameworks are allowed to be used in App Store apps. Private frameworks are intended to be used only by Apple's apps, and are more unstable against firmware changes, but many of the interesting features are in the private frameworks.

在那个页面上，我还看到了一个叫做 AppleBasebandManager 框架的东西，但它只支持 iOS 7。 什么是 iOS 7 中的 AppleBasebandManager 框架？

如果有人知道这件事，请提供详细信息。

Answer 1

由于这是一个未记录的私有(private)框架，我们无法确定它的作用是什么。从名称上看，我假设 Apple 使用它来管理“基带”操作。 Google search for ‘iPhone baseband’信息丰富:

A baseband processor is a device in a network interface that manages all the radio functions (all functions that require an antenna). This may not include Wi-Fi and/or Bluetooth.

— Baseband processor, Wikipedia :

iPhone baseband is essentially the cellular modem firmware that is on your iPhone.

所以我假设 AppleBasebandManager 是移动网络堆栈的接口(interface)。
