使用表格单元按钮执行操作时，在Firebase中使用分段控件未选择准确的文档。
我在Swift IOS和Firestore数据库中使用带有表视图的分段控件，
我能够按照细分控制要求从数据库加载文档。但是，当我点击表格单元格的按钮时，它仅处理一个文档，而不是准确的文档，我该如何确保表格单元格按钮仅处理与该文档的特定ID相关的文档，下面是代码我正在分享

var postAuthorname:String = ""
var PostTitle:String = ""

super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
// Do any additional setup after loading the view.
retrieveAllPosts()
}
