I know this question has been floated, but there are not any answers.我知道这个问题已经浮出水面，但没有任何答案。 In Objective C, is there a way to return signal strength?在目标 C 中，有没有办法返回信号强度？

Apple does not allow developers direct access to the low-level wireless API functions. Apple 不允许开发人员直接访问低级无线 API 功能。 It is possible to include some of these functions in your application (see the iphone-wireless project for example) but your application will not be accepted for inclusion in the iTunes store.可以在您的应用程序中包含其中一些功能（例如，请参阅iphone-wireless 项目），但您的应用程序不会被 iTunes 商店接受。

Previously some applications were allowed to do this (WiFiFoFum for example) but these applications have been removed from the store for using private APIs.以前允许某些应用程序执行此操作（例如 WiFiFoFum），但这些应用程序已从商店中删除以使用私有 API。

It's not documented API I believe, but you may git clone VAFieldTest in Github.我相信这不是文档化的 API，但是您可以在 Github 中 git clone VAFieldTest。 Search int result = CTGetSignalStrength();搜索int result = CTGetSignalStrength(); in this app.在这个应用程序中。 See the selected answer here: Measuring cellular signal strength在此处查看所选答案：测量蜂窝信号强度

If you just want to see the signal strength, call *3001#12345#* in the Phone app and it will shown in the status bar.如果您只想查看信号强度，请在电话应用中拨打*3001#12345#* ，它会显示在状态栏中。
