为什么我在 Swift 中没有收到来自 Firebase 的推送通知? [英] Why I do not get push notifications from Firebase in Swift?

问题描述

我在 AppDelegate 中设置了此代码:

I set this code in my AppDelegate:

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate { 

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    if #available(iOS 10.0, *) {
        let authOptions: UNAuthorizationOptions = [.Alert, .Badge, .Sound]
        UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(authOptions, completionHandler: { (granted: Bool, error: NSError?) in
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.currentNotificationCenter().delegate = self
            // For iOS 10 data message (sent via FCM)
            FIRMessaging.messaging().remoteMessageDelegate = self
        })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

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

还有这部分:

internal func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print(userInfo)
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print(userInfo)
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                   fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print(userInfo)
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    //Handle the notification
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification
}

我还将开发 APNs 上传到 Apple Developers.在 Firebase 控制台中，它写道通知已成功发送，但我没有收到任何推送通知.谁能帮我找出我的错误在哪里?

I also uploaded development APNs into the Apple Developers. In the Firebase console it writes that notification was successfully sent, but I do not get any push notification. Can anyone please help me to detect where my mistake is?

我已经为此工作了 3 天.搜索了很多，但一无所获.

I have worked on it for 3 days. Searched a lot, but nothing.
