测量蜂窝信号强度 [英] Measuring cellular signal strength

问题描述

我正在开发iOS版的非appstore应用程式。我想在我的代码中读取蜂窝信号强度。

I am developing a non-appstore app for iOS. I want to read the cellular signal strength in my code.

我知道苹果没有提供任何API，我们可以实现这一点。

I know Apple doesn't provide any API by which we can achieve this.

有没有可以用来实现这个的私人API？

Is there any private API that can be used to achieve this? I have gone through the various threads regarding this issue but could not find any relevant info.

这是完全可能的，因为有一个在应用商店中使用来检测运营商的信号强度。

It is completely possible because there is an app in the app-store for detecting the carrier's signal strength.

推荐答案

我简要地看了一下位于 Github 的VAFieldTest项目。

I briefly looked at the VAFieldTest project located at Github.

在类/类库中似乎有 getSignalStrength（）和 register_notification（） VAFieldTestViewController.m可能对你感兴趣，因为他们调用 CoreTelephony.framework 。

There seems to be getSignalStrength() and register_notification() functions in Classes/VAFieldTestViewController.m that might be interesting to you as they call into CoreTelephony.framework.

我非常相信一些使用的调用在来自Apple的CoreTelephony框架文档，因此为私有 - AppStore中的任何应用程序必须已通过检查。

I am pretty confident that some of the used calls are undocumented in the CoreTelephony framework documentation from Apple and therefore private - any app in the AppStore must have slipped passed inspection.
