在 iOS 中检查蜂窝网络类型 [英] Checking cellular network type in iOS

问题描述

我正在开发一个 iOS 应用程序，并想确定该设备具有哪种类型的蜂窝网络连接.

I am working on an iOS app, and want to determine which type of cellular connection the device has.

我对我的设备使用的蜂窝网络类型最感兴趣:2G 或 3G，或其他.

I'm most interested in the kind of cellular network my device is using: 2G or 3G, or other.

然而，Reachability.h 只提供对 wifi 或 3G 的检查.

However, the Reachability.h only provides checking for wifi or 3G.

我如何检查 2G、3G 等?

How can I check for 2G, 3G, etc?

推荐答案

2G/3G 无法通过 Reachability.h 或任何其他第三方库来区分，因为 iPhone 只提供网络类型信息( WWAN, WiFi , 无网络 ) 到 API.

2G / 3G cannot be distinguished via Reachability.h or any other third party libraries, as iPhone only provides network type information ( WWAN , WiFi , no Network ) to API.

但是，如果您能够知道 2G 或 3G 网络的 IP 范围，则可以确定 iPhone 使用的网络速度/频率.

However, if you are able to know the IP range of 2G or 3G network, you can determine which network speed / frequency the iPhone is using.
