[英]How to programmatically check if Mac is connected to Wi-Fi network?
I'm able to check if my Mac is connected to Internet using Reachability, but I don't understand how to specifically check Wi-Fi connection. 我可以使用Reachability检查我的Mac是否已连接到Internet,但我不明白如何专门检查Wi-Fi连接。 Any tips or Swift/Objective-C code are appreciated, thanks in advance.
提前感谢任何提示或Swift / Objective-C代码。
This code checks if the computer is connected to a wireless network. 此代码检查计算机是否已连接到无线网络。
It does not check if the wireless network is connected to the internet 它不检查无线网络是否连接到互联网
import CoreWLAN
func isWIFIActive() -> Bool {
let interfaceNames = CWInterface.interfaceNames()
for interfaceName in Array(interfaceNames) {
let interface = CWInterface(name: interfaceName as! String)
if interface.ssid() != nil {
return true
}
}
return false
}
isWIFIActive()
CWInterface(name:_)
is deprecated in 10.10 but still works CWInterface(name:_)
在10.10中已弃用,但仍然有效

A CWWiFiClient
based one-line solution for 10.10+: 基于
CWWiFiClient
单线解决方案:
func isWIFIActive() -> Bool {
return CWWiFiClient.interfaceNames()?.contains{ CWWiFiClient.shared().interface(withName: $0)?.ssid() != nil } ?? false
}
vadian answer without deprecations: vadian回答没有折旧 :
func isWIFIActive() -> Bool {
guard let interfaceNames = CWWiFiClient.interfaceNames() else {
return false
}
for interfaceName in interfaceNames {
let interface = CWWiFiClient.shared().interface(withName: interfaceName)
if interface?.ssid() != nil {
return true
}
}
return false
}
