recordFetchedBlock on CKQueryOperation未被调用

Question

我需要查询CKRecords的recordType“事件”。当我调用recordFetchedBlock时，我会将这些记录添加到我的数组中。然而，recordFetchedBlock从未被调用过。请帮帮我！谢谢：

    //TODO: Query for all Event records
    var database: CKDatabase = CKContainer.defaultContainer().privateCloudDatabase

    let truePredicate = NSPredicate(value: true)
    let eventQuery = CKQuery(recordType: "Event", predicate: truePredicate)

    let queryOperation = CKQueryOperation(query: eventQuery)

    queryOperation.recordFetchedBlock = { (record : CKRecord!) in

            self.eventsArray.append(record)
            println("recordFetchedBlock: \(self.eventsArray)")
    }

    queryOperation.queryCompletionBlock = { (cursor : CKQueryCursor!, error : NSError!) in

        println("queryCompletionBlock: \(self.eventsArray)")
    }

    database.addOperation(queryOperation)

所以我才意识到我的错误。我无意中调用了私有数据库上的查询(与公共数据库相反)。现在踢自己..。
