ios - FCM + Swift 3 - 通知未出现

Question

我知道您以前偶然发现过这个问题；事实上几次。但我遵循了提供给我的每一个建议here , here ，甚至 here .

(用Swift 3编写，运行在Xcode 8.1上)

是的，我在 Capabilities 中的推送通知已开启。甚至我的后台模式远程功能都打开了——我尝试打开和关闭 FirebaseAppDelegateProxy，检查了证书(为什么，是的，它指向正确的应用程序包)，移动了

application.registerForRemoteNotifications()

哭过，吃了大量的糖，向上帝祈祷，然后向我能想到的任何其他相关神灵祈祷，但仍然没有。

这可能只是对第二只眼睛的强烈需求，但有什么想法吗？

        }

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // 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.
    }

        // 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 full message.
        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)
    }
}

token 正在登录到控制台，FCM 已连接，云消息传递正在保存我的证书...我可能得到的唯一可能提示是 Firebase 控制台不将它发送消息的设备计算为 '发送'。

但是控制台看起来不错。

...但是消息在我的控制台中记录得很好。事实上，根本没有大喊大叫的错误!

感叹

我的手机没有从应用程序获得前景、背景或任何类型的通知 - 什么都没有。压缩。 Zilch。纳达。只是我心碎的声音。

我的 iPhone 目前运行的是 9.3.5。如果这有帮助的话。

任何帮助将不胜感激 - 或对替代推送通知系统的建议......

Answer 1

想通了。 附:我使用 Swift 3 语法，你在 willPresent 方法中缺少完成处理程序

completionHandler The block to execute with the presentation option for the notification. Always execute this block at some point during your implementation of this method.

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])

}
