如何在webview加载之前获取设备ID和设备令牌?

使用swift 3

在Xcode 8上运行

以下是我的ViewController.swift

class ViewController: UIViewController {

    @IBOutlet weak var TestWebview: UIWebView!
    override func viewDidLoad() {
        super.viewDidLoad()

        let deviceid = UIDevice.current.identifierForVendor!.uuidString

        //I want to pass device id and device token to this testURL
        let testURL = URL(string: "http://www.test.com/user.html?device=ios&deviceid=" + deviceid + "&devicetoken=")


        let testURLRequest = URLRequest(url: testURL!)
        TestWebview(testURLRequest)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

下面是我的AppDelegate.swift文件

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        let center = UNUserNotificationCenter.current()

        center.requestAuthorization(options: [.alert, .sound, .badge], completionHandler: { granted, error in
            if granted {
                print("Yes。")
            }
            else {
                print("No!")
            }
        })

        application.registerForRemoteNotifications()

        return true
    }


    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

        let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
        print("===== deviceTokenString =====")
        print(deviceTokenString)
    }

}

现在,我可以在ViewController中获取设备ID,并在AppDelegate文件中获取设备令牌。

但是,如何将设备令牌传递给ViewController中的testURL,或者如何将设备ID和设备令牌传递给testURL?

deviceTokenString课程中为AppDelegate设置一个属性。

class AppDelegate: UIResponder, UIApplicationDelegate {
    ...
    var deviceTokenString: String?
    ...
    ...
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        // feed your property
        deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
        print("===== deviceTokenString =====")
        print(deviceTokenString)
    }
}

现在,您可以从任何控制器获取deviceTokenString之类的内容:

override func viewDidLoad() {
    super.viewDidLoad()

    guard let appDelegate = UIApplication.shared.delegate as? AppDelegate else {
        return 
    } 
    guard let deviceTokenString = appDelegate.deviceTokenString else {
        // deviceTokenString isn't available
        return
    }
    // deviceTokenString is available here

    let deviceid = UIDevice.current.identifierForVendor!.uuidString

    // I want to pass device id and device token to this testURL
    // Concat various types into string like below
    let testURL = URL(string: "http://www.test.com/user.html?device=ios&deviceid=\(deviceid)&devicetoken=\(deviceTokenString)")


    let testURLRequest = URLRequest(url: testURL!)
    TestWebview(testURLRequest)
}
