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,我还看到了一个名为AppleBasebandManager框架的东西,但它只支持iOS 7.
iOS 7中的AppleBasebandManager框架是什么？

如果有人知道这个细节.

最佳答案 由于这是一个未记录的私有框架,我们无法确切知道它的作用是什么.从名称来看,我认为Apple会用它来管理“基带”操作. A
Google search for ‘iPhone baseband’提供信息：

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.

所以我认为AppleBasebandManager是移动网络堆栈的接口.
