在Swift 2中获取SSID

问题描述

我试图使用此代码获取SSID

Im trying to use this code to get SSID

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func getSSID() -> String{
        var currentSSID = ""
        let interfaces = CNCopySupportedInterfaces()
        if interfaces != nil {
            let interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]
            if interfacesArray.count > 0 {
                let interfaceName = interfacesArray[0] as String
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData.takeRetainedValue() as Dictionary!
                    currentSSID = interfaceData[kCNNetworkInfoKeySSID] as! String
                    let ssiddata = NSString(data:interfaceData[kCNNetworkInfoKeySSIDData]! as! NSData, encoding:NSUTF8StringEncoding) as! String
                    // ssid data from hex
                    print(ssiddata)
                }
            }
        }
        return currentSSID
    }
}

但是在此行中收到错误
let interfacesArray = interfaces.takeRetainedValue（）as [String：AnyObject]

But in getting an error in this linelet interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]

错误是

'CFArray'类型的值没有成员'takeRetainedValue'

感谢您的帮助

推荐答案

这可以帮助你（在Swift 2上测试）：

This may help you (tested on Swift 2):

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func fetchSSIDInfo() -> String {
        var currentSSID = ""
        if let interfaces = CNCopySupportedInterfaces() {
            for i in 0..<CFArrayGetCount(interfaces) {
                let interfaceName: UnsafePointer<Void> = CFArrayGetValueAtIndex(interfaces, i)
                let rec = unsafeBitCast(interfaceName, AnyObject.self)
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)")
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData! as Dictionary!
                    currentSSID = interfaceData["SSID"] as! String
                }
            }
        }
        return currentSSID
    }
}

我从Ray Wenderlich的网站上获取并修改了代码（曾经在这里：
但现在特定线程已从网站中删除了）

I took and adapted the code from Ray Wenderlich's site (once was here:Retrieve SSID in iOS9 but now the specific thread has been removed from site)

这篇关于在Swift 2中获取SSID的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
