通过 Firebase 的 iOS 推送通知不起作用

Question

您好，我正在制作一个 iPhone 应用，通过 Google 的 Firebase 发送推送通知。我使用 Swift 和 Xcode 进行编程。当我打开应用程序时，系统会要求我允许推送通知，但是当我从 Firebase 控制台发送通知时，我没有收到任何通知。我想知道你是否可以帮助我。我正在使用 Ad Hoc 导出将 .isa 传输到我 friend 的 iPhone 并以这种方式进行测试。我完全按照 Firebase 教程进行操作 - 添加 .plist、cocoa pod，并在项目设置中上传了证书。我有一个付费的苹果开发者帐户。

import UIKit
import CoreData
import Firebase
import FirebaseMessaging


@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    FIRApp.configure()

    let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Alert,UIUserNotificationType.Badge,UIUserNotificationType.Sound]

    let notificationSettings = UIUserNotificationSettings(forTypes:notificationTypes, categories:nil)

    application.registerForRemoteNotifications()
    application.registerUserNotificationSettings(notificationSettings)
    return true
}


func applicationWillResignActive(application: UIApplication) {
}

func applicationDidEnterBackground(application: UIApplication) {
}

func applicationWillEnterForeground(application: UIApplication) {
}

func applicationDidBecomeActive(application: UIApplication) {
}

func applicationWillTerminate(application: UIApplication) {
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    print("MessageID : \(userInfo["gcm_message_id"]!)")
    print("%@", userInfo)

   }
}

您还需要做一些事情。当您 registerForRemoteNotifications 时，您会收到一个 APNS token ，您需要将其提供给 Firebase。这是在应用程序 didRegisterForRemoteNotificationsWithDeviceToken 中完成的。

import UIKit
import CoreData
import Firebase
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    override init() {

        super.init()

        FIRApp.configure()
    }

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        application.registerForRemoteNotifications()
        application.registerUserNotificationSettings(
            UIUserNotificationSettings(
                forTypes: [.Alert, .Badge, .Sound],
                categories: nil
            )
        )

        NSNotificationCenter.defaultCenter().addObserver(self,
            selector: #selector(tokenRefreshNotification),
            name: kFIRInstanceIDTokenRefreshNotification,
            object: nil
        )

        return true
    }

    func applicationDidEnterBackground(application: UIApplication) {

        FIRMessaging.messaging().disconnect()
    }

    func applicationDidBecomeActive(application: UIApplication) {

        FIRMessaging.messaging().connectWithCompletion { (error) in

            switch error {
            case .Some:
                print("Unable to connect with FCM. \(error)")
            case .None:
                print("Connected to FCM.")
            }
        }
    }

    func applicationWillResignActive(application: UIApplication) {}

    func applicationWillEnterForeground(application: UIApplication) {}

    func applicationWillTerminate(application: UIApplication) {}

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

        FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .Sandbox)
    }

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                     fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

        print("MessageID : \(userInfo["gcm.message_id"]!)")
        print("%@", userInfo)
    }

    func tokenRefreshNotification(notification: NSNotification) {

        if let refreshedToken = FIRInstanceID.instanceID().token() {
            print("Instance ID token: \(refreshedToken)")
        }

        applicationDidBecomeActive(UIApplication.sharedApplication())
    }
}
