FCM + Swift 3 - 通知未出现

9

我知道你之前已经看过这个问题,甚至多次看过。但是我遵循了所有提供给我的建议,在这里在这里,甚至在这里

(使用Swift 3编写,在Xcode 8.1上运行)

是的,我的推送通知功能在Capabilities中已经开启了。甚至我的后台模式远程功能也已经开启 - 我尝试切换FirebaseAppDelegateProxy的开关,检查证书(没错,它指向正确的应用程序包),移动

application.registerForRemoteNotifications()

我哭了,吃了大量的糖,向上帝和其他我能想到的相关神灵祈祷,但仍然毫无结果。

可能只是需要另一个人来看一下,有什么想法吗?

        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {

    }

    }

    }

        // this callback will not be fired till the user taps on the notification launching the application.
        // TODO: Handle data of notification

        // Print message ID.
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")

        print(userInfo)
    }

    private func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
//        let tokenChars = deviceToken.bytes
        var tokenString = ""

        for i in 0..<deviceToken.length {
            tokenString += String(format: "%02.2hhx", arguments: [[deviceToken.bytes as! CVarArg][i]])
        }

        FIRInstanceID.instanceID().setAPNSToken(deviceToken as Data, type: FIRInstanceIDAPNSTokenType.unknown)

        print("tokenString: \(tokenString)")
    }
}

这里是扩展...

import Foundation
import UserNotifications
import FirebaseMessaging

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

    // Receive displayed notifications for iOS 10 devices.

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        // Print message ID.
        print("Message ID: \(userInfo["gcm.message_id"]!)")

        // Print full message.
        print("%@", userInfo)

    }

}

extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("%@", remoteMessage.appData)
    }
}

令牌已登录到控制台,FCM已连接,云消息保持我的证书…我唯一可能有的提示是Firebase控制台不将发送消息的设备视为“已发送”。enter image description here但控制台看起来很好。

...但是我的控制台日志记录得非常好。实际上,根本没有任何错误!

叹气

我的手机无法从应用程序中获取前景、背景或任何通知 - 没有任何东西。零。没有。只有我心碎的声音。

我的iPhone目前运行在9.3.5上。如果这有所帮助。

任何帮助都将不胜感激 - 或者提供替代推送通知系统的建议...


你是从 Firebase 控制台还是从你的应用服务器发送通知?如果是从应用服务器发送,请添加一个样例负载。 - AL.
从 Firebase 控制台。 - Misha Stone
有什么进展了吗?我目前也处于同样的情况。 - CharlesAE

搞定了。 p.s.我正在使用Swift 3语法,你在willPresent方法中缺少completionHandler。

completionHandler 带有通知呈现选项的执行块。在实现此方法期间始终执行此块。

https://developer.apple.com/reference/usernotifications/unusernotificationcenterdelegate/1649518-usernotificationcenter

func userNotificationCenter(_ center: UNUserNotificationCenter,
                            willPresent notification: UNNotification,
                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    let userInfo = notification.request.content.userInfo as! [String: Any]



    completionHandler([.alert, .badge, .sound])

}

啊,原来是这样。我最终通过一遍又一遍地复制粘贴示例代码来修复我的错误。感谢您指出了它的具体问题! - Misha Stone
这是否正确?原帖中说:“我的iPhone目前运行的是9.3.5版本。”,然而这个函数(以及你提供的文档)却说明它适用于SDK 10.0及以上版本。 - tospig

如果您确定您的代码是完美的,但仍然无法接收FCM通知,请从Firebase控制台更新p12证书。您只需从推送证书中导出安全密钥并上传即可。您将开始接收通知。
