CloudKit 通知不会到达生产环境(AppStore、TestFlight)，但会在开发模式下工作(从 Xcode 安装)。

为什么？

这是我注册远程通知的方式:

    let center = UNUserNotificationCenter.current()

    center.delegate = self
    center.requestAuthorization(options: [.alert, .badge, .sound]) { authorised, error in

        DispatchQueue.main.sync {
            application.registerForRemoteNotifications()
        }
    }

这就是我保存订阅的方式:

func subscribeForChanges() {

    let options: CKQuerySubscriptionOptions = [.firesOnRecordCreation, .firesOnRecordUpdate, .firesOnRecordDeletion]

    let serviceSubscription = CKQuerySubscription(recordType: "Service", predicate: NSPredicate(value: true), options: options)
    let goalSubscription = CKQuerySubscription(recordType: "Goal", predicate: NSPredicate(value: true), options: options)
    let territorySubscription = CKQuerySubscription(recordType: "Territory", predicate: NSPredicate(value: true), options: options)
    let addressSubscription = CKQuerySubscription(recordType: "Address", predicate: NSPredicate(value: true), options: options)
    let noteSubscription = CKQuerySubscription(recordType: "Note", predicate: NSPredicate(value: true), options: options)
    let daySubscription = CKQuerySubscription(recordType: "Day", predicate: NSPredicate(value: true), options: options)
    let shareSubscription = CKQuerySubscription(recordType: "cloudkit.share", predicate: NSPredicate(value: true), options: options)

    let notificationInfo = CKNotificationInfo()
    notificationInfo.shouldBadge = false
    notificationInfo.shouldSendContentAvailable = true

    serviceSubscription.notificationInfo = notificationInfo
    goalSubscription.notificationInfo = notificationInfo
    territorySubscription.notificationInfo = notificationInfo
    addressSubscription.notificationInfo = notificationInfo
    noteSubscription.notificationInfo = notificationInfo
    daySubscription.notificationInfo = notificationInfo
    shareSubscription.notificationInfo = notificationInfo

    let privateSubscriptionsOperation = CKModifySubscriptionsOperation(subscriptionsToSave: [serviceSubscription, goalSubscription, territorySubscription, addressSubscription, noteSubscription, daySubscription, shareSubscription], subscriptionIDsToDelete: nil)
    privateSubscriptionsOperation.database = CloudAssistant.shared.privateDatabase

    let notificationInfoDatabaseSubscription = CKNotificationInfo()
    notificationInfoDatabaseSubscription.shouldSendContentAvailable = true

    let subscription = CKDatabaseSubscription(subscriptionID: "pl.blue-world.fieldservice.sharedDatabase")
    subscription.notificationInfo = notificationInfoDatabaseSubscription
    let sharedSubscriptionsOperation = CKModifySubscriptionsOperation(subscriptionsToSave: [subscription], subscriptionIDsToDelete: nil)
    sharedSubscriptionsOperation.database = CloudAssistant.shared.sharedDatabase

    let queue = OperationQueue()
    queue.maxConcurrentOperationCount = 1
    queue.addOperation(privateSubscriptionsOperation)
    queue.addOperation(sharedSubscriptionsOperation)
    privateDatabase.save(CKRecordZone(zoneName: "fieldservice")) { _, _ in }
}

最佳答案

当类似的事情发生在我身上时，这是由于混淆了开发环境和生产环境之间的服务器更改 token 造成的。在我的例子中，开发更改 token 是 aaabbb，而产品更改 token 是更早的东西，比如 aaaaab。由于我无意中使用了 dev change token，它“领先于”prod。

我看到你已经编辑了你的问题，但正如我从以前的版本中记忆的那样，我相信你已经配置了 xcode 构建以使用 prod env。但是，有一个简单的测试可以证明或反驳该理论是否与您的问题相关。在您未收到通知的环境中启动应用程序后，请调用

CKFetchNotificationChangesOperation

使用 Nil 作为服务器更改 token 。从一开始就应该为该用户返回每个通知。如果结果包括丢失的通知，那么问题可能出在您处理更改 token 的方式上。

否则，我会使用

CKFetchSubscriptionOperation

在 xcode 构建和 testflight 构建上，比较两组，密切注意谓词。我希望列表是相同的，因为您已经在使用 prod env，但我会在寻找更复杂的原因之前排除这个简单的测试。

关于ios - 为什么从 testflight 安装应用程序时 cloudkit 通知没有到达，而从 xcode 编译时它可以工作？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47611763/
