如何使用swift在iOS中获取可用的wifi网络名称 [英] How to get available wifi network name in iOS using swift

问题描述

我希望获得某个地区的所有WiFi网络及其SSID值。但问题是如何使所有WiFi网络的SSID可用，即使我没有连接到它。

I want to get all the WiFi networks available in a region and their SSID value. But the problem is how to get the SSID of all the WiFi network available even if I am not connected to one.

推荐答案

首先;

import SystemConfiguration.CaptiveNetwork

import SystemConfiguration.CaptiveNetwork

然后;

 func getInterfaces() -> Bool {
    guard let unwrappedCFArrayInterfaces = CNCopySupportedInterfaces() else {
        print("this must be a simulator, no interfaces found")
        return false
    }
    guard let swiftInterfaces = (unwrappedCFArrayInterfaces as NSArray) as? [String] else {
        print("System error: did not come back as array of Strings")
        return false
    }
    for interface in swiftInterfaces {
        print("Looking up SSID info for \(interface)") // en0
        guard let unwrappedCFDictionaryForInterface = CNCopyCurrentNetworkInfo(interface) else {
            print("System error: \(interface) has no information")
            return false
        }
        guard let SSIDDict = (unwrappedCFDictionaryForInterface as NSDictionary) as? [String: AnyObject] else {
            print("System error: interface information is not a string-keyed dictionary")
            return false
        }
        for d in SSIDDict.keys {
            print("\(d): \(SSIDDict[d]!)")
        }
    }
    return true
}
