Ios Cloudkit:CKDatabaseOperation在蜂窝网络上不工作

大家好，所有

CloudKit

用户：

我花了很长时间试图找出为什么

CKDatabaseOperation

不提供任何反馈。在手机上保存

CKRecords

时没有错误，没有回调

---

你能告诉我你对此有什么看法吗？

苹果开发者论坛上有人找到了一个解决方案：

当设置

qualityOfService=.UserInitiated

示例：

let publicDB = CKContainer.defaultContainer().publicCloudDatabase    
let operation = CKModifyRecordsOperation(recordsToSave: [aRecord], recordIDsToDelete: nil)

operation.allowsCellularAccess = true
operation.qualityOfService = .UserInitiated // <----- THATS THE CELLULAR FIX

operation.perRecordProgressBlock = {(record, progress) in
    print("Progress: \(Int(progress*100.0))%")
}
operation.perRecordCompletionBlock = {(record, error) in
    print("Upload complete") //Add awesome error handling here
}
publicDB.addOperation(operation)

让publicDB=CKContainer.defaultContainer（）.publicCloudDatabase
let operation=CKModifyRecordsOperation（recordsToSave:[AreRecord]，recordIDsToDelete:nil）
operation.AllowCellularAccess=true
operation.qualityOfService=.UserInitiated//可能存在的重复项
