Is there an API in CocoaTouch/iOS for detecting wireless networks? I want to write an app that saves a list of networks the phone can see at a given moment.

推荐答案

知道您可以使用 CNCopySupportedInterfaces 和 CNCopyCurrentNetworkInfo ：//developer.apple.com/library/ios/#documentation/SystemConfiguration/Reference/CaptiveNetworkRef/Reference/reference.htmlrel =nofollow> CaptiveNetwork 。您可以参考：我如何请使用CaptiveNetwork获取更多信息的当前WiFi热点名称。

As far as I know you can get the information about the current connected Wi-Fi using CNCopySupportedInterfaces and CNCopyCurrentNetworkInfo of CaptiveNetwork. You can refer to: How do I use CaptiveNetwork to get the current WiFi Hotspot Name for more information.

：

According to iPhone get a list of all SSIDs without private library:

Without the use of private library (Apple80211) you can only get the SSID of the network your device is currently connected to.

您可以查看 iphone-wireless 项目。有一个示例应用程序 Stumber ，它完全按照您的要求。但是如果您要发布到App Store，则无法在您的应用中使用此方法，因为它使用私有API

You could have a look at iphone-wireless project if you are interested in Apple80211. There exists a sample app "Stumber" which does exactly what you want. But you cannot use this in your app if you want to publish to App Store because as it uses private APIs
