使用以前CKQueryOperation的结果运行CKQueryOperation

// 假设我们有一个函数来执行查询操作
func performQueryOperation(query: CKQuery, completion: @escaping ([CKRecord]?) -> Void) {
    let operation = CKQueryOperation(query: query)
    
    operation.recordFetchedBlock = { record in
        // 处理每个检索到的记录
    }
    
    operation.queryCompletionBlock = { cursor, error in
        if let error = error {
            print("查询操作失败: \(error)")
            completion(nil)
            return
        }
        
        // 假设我们想要基于前一个查询的结果运行另一个查询
        if let lastRecordID = cursor?.recordID {
            let newQuery = CKQuery(recordType: "NewRecordType", predicate: NSPredicate(format: "relatedRecordID == %@", lastRecordID))
            performQueryOperation(query: newQuery, completion: completion)
        } else {
            completion(nil) // 没有更多的记录
        }
    }
    
    // 执行操作
    let database = CKContainer.default().privateCloudDatabase
    database.add(operation)
}

// 使用函数执行初始查询
let initialQuery = CKQuery(recordType: "InitialRecordType", predicate: NSPredicate(value: true))
performQueryOperation(query: initialQuery) { records in
    // 处理最终的查询结果
}
