在swift3中列出所有可用的无线网络SSID我试过但我只获得连接的无线网络SSID就可以了

func fetchSSIDInfo() ->  String {
    var currentSSID = ""
    if let interfaces:CFArray = CNCopySupportedInterfaces() {
        print(interfaces)
        for i in 0..<CFArrayGetCount(interfaces){
            let interfaceName: UnsafeRawPointer = CFArrayGetValueAtIndex(interfaces, i)
            let rec = unsafeBitCast(interfaceName, to: AnyObject.self)
            let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)" as CFString)
            if unsafeInterfaceData != nil {
                let interfaceData = unsafeInterfaceData! as Dictionary!
                for dictData in interfaceData! {
                    if dictData.key as! String == "SSID" {
                        currentSSID = dictData.value as! String
                    }
                }
            }
        }
    }
    return currentSSID
}

Answer 1

iOS仅返回已连接的SSID。无法在代码中获取其他SSID，无论是Swift还是ObjectiveC。

Answer 2

根据Apple的理念，您无法访问硬件，因此您无法查询低级别的详细信息：您所要求的内容要求Apple公开他们认为不安全的低级别电话。并且Yoy不能直接打电话给HW，也不能写一个驱动程序......
