[1024 还在加班] iOS 怎么判断设备的 WiFi 开关是否打开？

This topic created in 4030 days ago, the information mentioned may be changed or developed.

由于客户的某些 SB 要求，偏要监控设备的 WiFi 的开关是否打开，我 Google 了大半圈，硬是没有找到，难道只能监控网络的状态，不能监控 WiFi 开关是否打开吗？求解答……

func getSSID() -> String {

let interfaces = CNCopySupportedInterfaces()
if interfaces == nil {
return "WiFi Not Found"
// Simulator
}

let interfacesArray = interfaces.takeRetainedValue() as! [String]
if interfacesArray.count <= 0 {
return "Error"
}

let interfaceName = interfacesArray[0] as String
let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
if unsafeInterfaceData == nil {
return "No WiFi Connected"
// 4G
}

let interfaceData = unsafeInterfaceData.takeRetainedValue() as Dictionary!

return interfaceData["SSID"] as! String

}

这是我在 TodayWiFi 里的代码，忘了是哪个答案里找来的了
