从Firebase中检索数据后，如何将检索到的数据从一个视图控制器发送到另一个视图控制器？ [英] After retrieving data from Firebase, how to send retrieved data from one view controller to another view controller?

问题描述

这是我在Firebase 此处创建的表格。我有一个搜索按钮。按钮动作将首先从firebase中获取数据，然后将其发送到另一个视图控制器，并将显示在一个表视图。但主要的问题是，在从Firebase获取所有数据之前，bb

$ p $ self.performSegueWithIdentifier（SearchResultPage，sender：self）

触发器，我的下一个视图控制器显示一个空的表视图。这是我的努力 here 。

从这篇文章这里我认为我的代码没有放置

解决方案

$ b $完成for循环后，在if块中的dataTransfer方法中写下这行代码b

  self.performSegueWithIdentifier（SearchResultPage，sender：self）
  

This is my table created in Firebase here. I have a search button. The button action will be at first it will fetch data from firebase and then it will send it to another view controller and will show it in a table view. but main problem is that before fetching all data from Firebase

self.performSegueWithIdentifier("SearchResultPage", sender: self )

triggers and my next view controller shows a empty table view. Here was my effort here.

From this post here I think that my code is not placed well.

解决方案

Write this line of code in your dataTransfer method in if block after complete for loop

self.performSegueWithIdentifier("SearchResultPage", sender: self )
