ios - CloudKit - 无法从 iCloud 检索数据

Question

当应用程序 (iOS9) 通过 Xcode 运行或从 App Store 下载时，通过 CloudKit 从 iCloud 发送和接收数据有什么区别吗？

我的问题是:从Xcode启动的应用程序成功接收并显示数据，在App Store中发布的同一应用程序无法显示数据...

哪里可能出现错误？

谢谢。

func getRecordsFromCloud() {
        // Fetch data using Convenience API
        let cloudContainer = CKContainer.defaultContainer()
        let publicDatabase = cloudContainer.publicCloudDatabase
        let predicate = NSPredicate(value: true)
        let query = CKQuery(recordType: "Pivo", predicate: predicate)
        query.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]

        // Create the query operation with the query
        let queryOperation = CKQueryOperation(query: query)
        queryOperation.desiredKeys = ["name", "type", "location"]
        queryOperation.queuePriority = .VeryHigh
        queryOperation.resultsLimit = 50
        queryOperation.recordFetchedBlock = { (record:CKRecord!) -> Void in
            if let restaurantRecord = record {
                self.restaurants.append(restaurantRecord)
            }
        }

        queryOperation.queryCompletionBlock = { (cursor:CKQueryCursor?, error:NSError?) -> Void in
            if (error != nil) {
                print("Failed to get data from iCloud - \(error!.localizedDescription)")
                return
            }

            print("Successfully retrieve the data from iCloud")
            self.refreshControl?.endRefreshing()
            NSOperationQueue.mainQueue().addOperationWithBlock() {
                self.spinner.stopAnimating()
                self.tableView.reloadData()
            }

        }

        // Execute the query
        publicDatabase.addOperation(queryOperation)
    }
