Swift 2 和 Cloudkit 的通知

Question

我正在制作一个 "texting app" 你可以调用它并且它使用 cloudkit 我一直在到处寻找添加与 cloudkit 一起使用的通知......有人能详细告诉我为 cloudkit 添加推送通知的代码，因为我很迷茫......我也不希望通知转到不同的 "texting rooms" （在 cloudkit 中它会是记录类型...）例如，我有一种记录类型称为 "text"，另一种记录类型称为 "text 2" 我不希望来自 "text" 的通知到达使用 [=19 的人=] 反之亦然。

使用 Swift 2.0 和 El Captain & Xcode 7.2.1

Elia，您需要将其添加到您的应用委托中。它将到达 userInfo 数据包，然后您可以解析它以查看哪个 database/app 发送了它。

UIApplicationDelegate to the class
application.registerForRemoteNotifications() to the

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

比这个方法

func application(application: UIApplication, didReceiveRemoteNotification  userInfo: [NSObject : AnyObject]) {
    let notification = CKQueryNotification(fromRemoteNotificationDictionary: userInfo as! [String : NSObject])

    let container = CKContainer(identifier: "iCloud.com")
    let publicDB = container.publicCloudDatabase

    if notification.notificationType == .Query {
        let queryNotification = notification as! CKQueryNotification
        if queryNotification.queryNotificationReason  == .RecordUpdated {
            print("queryNotification.recordID \(queryNotification.recordID)")
            // Your notification

        }
    }

    print("userInfo \(userInfo["ck"])")
                    NSNotificationCenter.defaultCenter().postNotificationName("NotificationIdentifier", object: self, userInfo:dataDict)
                }
            }
        }
    }

}

这会让你开始。

您可以使用此方法以编程方式检查您的订阅，当然在开发过程中您可以使用仪表板。

func fetchSubsInPlace() {
    let container = CKContainer(identifier: "iCloud.com")
    let publicDB = container.publicCloudDatabase

    publicDB.fetchAllSubscriptionsWithCompletionHandler({subscriptions, error in
        for subscriptionObject in subscriptions! {
            let subscription: CKSubscription = subscriptionObject as CKSubscription
            print("subscription \(subscription)")
        }
    })
}

当你终于得到它时；您可以执行此例程以确保在您的应用程序休眠时捕获您错过的任何订阅，并确保订阅不会发送到您的所有设备，一旦您处理了它们。

 func fetchNotificationChanges() {
    let operation = CKFetchNotificationChangesOperation(previousServerChangeToken: nil)

    var notificationIDsToMarkRead = [CKNotificationID]()

    operation.notificationChangedBlock = { (notification: CKNotification) -> Void in
        // Process each notification received
        if notification.notificationType == .Query {
            let queryNotification = notification as! CKQueryNotification
            let reason = queryNotification.queryNotificationReason
            let recordID = queryNotification.recordID

            print("reason \(reason)")
            print("recordID \(recordID)")
            // Do your process here depending on the reason of the change

            // Add the notification id to the array of processed notifications to mark them as read
            notificationIDsToMarkRead.append(queryNotification.notificationID!)
        }
    }

    operation.fetchNotificationChangesCompletionBlock = { (serverChangeToken: CKServerChangeToken?, operationError: NSError?) -> Void in
        guard operationError == nil else {
            // Handle the error here
            return
        }

        // Mark the notifications as read to avoid processing them again
        let markOperation = CKMarkNotificationsReadOperation(notificationIDsToMarkRead: notificationIDsToMarkRead)
        markOperation.markNotificationsReadCompletionBlock = { (notificationIDsMarkedRead: [CKNotificationID]?, operationError: NSError?) -> Void in
            guard operationError == nil else {
                // Handle the error here
                return
            }
        }

        let operationQueue = NSOperationQueue()
        operationQueue.addOperation(markOperation)
    }

    let operationQueue = NSOperationQueue()
    operationQueue.addOperation(operation)
}


}
