我正在尝试显示所有可用的WIFI连接.它不起作用.这是我的代码：
import Foundation
import CoreWLAN
var cwInterface = CWInterface()
do {
let routers = try cwInterface.scanForNetworksWithSSID(nil)
print(routers)
} catch let error as NSError {
print("Error: \(error.localizedDescription)")
}
我没有得到任何结果.我做错了什么？
如果使用接口名称初始化CWInterface,它将起作用,例如“en1”.
但最好不使用带编码的名称,因此我们还将使用CWWiFiClient.sharedWiFiClient().interface()返回默认的WIFI接口.
管理所有这些的类的示例：
class discovery {
var currentInterface: CWInterface
var interfacesNames: [String] = []
var networks: Set<CWNetwork> = []
// Failable init using default interface
init?() {
if let defaultInterface = CWWiFiClient.sharedWiFiClient().interface(),name = defaultInterface.interfaceName {
self.currentInterface = defaultInterface
self.interfacesNames.append(name)
self.findNetworks()
} else {
return nil
}
}
// Init with the literal interface name,like "en1"
init(interfaceWithName name: String) {
self.currentInterface = CWInterface(interfaceName: name)
self.interfacesNames.append(name)
self.findNetworks()
}
// Fetch detectable WIFI networks
func findNetworks() {
do {
self.networks = try currentInterface.scanForNetworksWithSSID(nil)
} catch let error as NSError {
print("Error: \(error.localizedDescription)")
}
}
}
使用默认界面调用它：
if let discovery = discovery() {
print(discovery.networks)
for network in discovery.networks {
print(network.ssid!)
}
}
或者使用接口名称：
let discovery = discovery(interfaceWithName: "en1") let results = discovery.networks
结果包含所有扫描的网络：
[<CWNetwork: 0x608000001bd0> [ssid=SomeNetworkName,bssid=xxxx,security=WPA Enterprise,RSSi=xx,channel=<CWChannel: 0x600000004fb0> [channelNumber=11(2GHz),channelWidth={20MHz}],ibss=0],etc]
