iOS开发实时检测网络状态

pod 'RealReachability'

// 封装

import UIKit

// 使用

// 1. AppDelegate
import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // 开启实时检测网络状态
        startRealTimeMonitorNetworkStatus()
        return true
   }


// 2. ViewController
import UIKit

class ViewController: LCZBaseViewController,LCZRealStatusDelegate {
  // 必须写在这里
   override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        let lcz = LCZRealReachabilityTool.shared
        lcz.delegate = self
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    }
// 实现代理方法
func LCZRealStatusUnknown() {
        LCZSVProgressHUDTool.dismiss()
        LCZSVProgressHUDTool.show(title: "LCZRealStatusUnknown")
    }
    
    func LCZRealStatusNotReachable() {
        LCZSVProgressHUDTool.dismiss()
        LCZSVProgressHUDTool.show(title: "LCZRealStatusNotReachable")
    }
    
    func LCZRealStatusViaWWAN() {
        LCZSVProgressHUDTool.dismiss()
        LCZSVProgressHUDTool.show(title: "LCZRealStatusViaWWAN")
    }
    
    func LCZRealStatusViaWiFi() {
        LCZSVProgressHUDTool.dismiss()
        LCZSVProgressHUDTool.show(title: "LCZRealStatusViaWiFi")
    }
