我想要类似的功能AFNetworking在 Objective-C 中，在 Swift 中使用 Alamofire NetworkReachabilityManager：
//Reachability detection
[[AFNetworkReachabilityManager sharedManager] startMonitoring];
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusReachableViaWWAN: {
[self LoadNoInternetView:NO];
break;
}
case AFNetworkReachabilityStatusReachableViaWiFi: {
[self LoadNoInternetView:NO];
break;
}
case AFNetworkReachabilityStatusNotReachable: {
break;
}
default: {
break;
}
}
}];
我目前正在使用监听器来了解网络状态的变化
let net = NetworkReachabilityManager()
net?.startListening()
有人可以描述如何支持这些用例吗？
网络管理类
class NetworkManager {
//shared instance
static let shared = NetworkManager()
let reachabilityManager = Alamofire.NetworkReachabilityManager(host: "www.google.com")
func startNetworkReachabilityObserver() {
reachabilityManager?.listener = { status in
switch status {
case .notReachable:
print("The network is not reachable")
case .unknown :
print("It is unknown whether the network is reachable")
case .reachable(.ethernetOrWiFi):
print("The network is reachable over the WiFi connection")
case .reachable(.wwan):
print("The network is reachable over the WWAN connection")
}
}
// start listening
reachabilityManager?.startListening()
}
}
启动网络可达性观察器
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// add network reachability observer on app start
NetworkManager.shared.startNetworkReachabilityObserver()
return true
}
}
