(Swift)NetworkUtil Monitor the network

Preface

2022.06.23 Today I wrote a ios13 And above monitor network encapsulation . You can get the current network status , When the network changes, you will be notified

On the subject

It is very convenient to use

1. Enable network monitoring when starting

2. Then you can use it wherever you want

import UIKit
import SnapKit

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .white

        // Get the enumeration of network status 
        print("connectType: \(NetworkUtil.shared.connectType.rawValue)")
        // Get the text value of the network status 
        print("readableConnectType: \(NetworkUtil.shared.readableConnectType)")
        // Register for network monitoring 
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(onNetworkChange),
            name: Notification.Name("onNetworkChange"),
            object: nil
        )
    }
  
    // Once the network changes, it will be notified 
    @objc func onNetworkChange(notification : Notification){
        DispatchQueue.main.async {
            guard
                let dictionary = notification.userInfo,
                let type = dictionary["type"] as? Int
            else {
                return
            }

            let connectType = NetworkUtil.ConnectType(rawValue: type)!

            switch (connectType) {
            case .unknown:
                print(" No network available at present ")
            default:
                break
            }
        }
    }
}
