如何在xib中将UITableView作为子视图添加到UIView? [英] How to add a UITableView as a subview to a UIView in xib?

问题描述

我有一个使用xib文件构建的自定义视图.在此自定义视图中，有一个UIView，我想在其中添加一个静态UITableView作为子视图.此处显示的UITableView存在于storyboard上并与UITableViewController关联.我做了以下事情:

I have a custom view that I built using xib file. In this custom view, there is a UIView where I would like to add a static UITableView as a subview. The UITableView to be shown here is present on the storyboard and associated to a UITableViewController. I did the following:

let vc = (UIStoryboard(name: "Main", bundle: nil))
    .instantiateViewControllerWithIdentifier("tableController") as! TableController
vc.loadViewIfNeeded()
table = vc.table // this is an outlet, I'm sure it is not nil
table.delegate = vc
table.dataSource = vc
table.backgroundColor = UIColor.greenColor()
containerView.addSubview(table)

我可以在自定义视图上看到绿色背景，但是未显示表格单元格

I can see the green background on my custom view but the table cells are not being displayed

我知道该表的出口不是零，因为在调试时，如果我使用控制台下方的Quick Look图标检查table变量，则可以看到该表.

I know the outlet to the table is not nil because when debugging if I inspect the table variable using the Quick Look icon below the console, I can see the table.

更新

我意识到我的方法不是一个好方法.

I realized my approach was not a good one.

通过将View设为UITableViewDataSource和UITableViewDelegate的子视图，并以编程方式创建UITable和必需的TableViewCell，从而获得了所需的结果.疯狂的代码量！！

I achieved the results I wanted by making my View a subview of UITableViewDataSource and UITableViewDelegate and programmatically creating a UITable and a required TableViewCell. Crazy amounts of codes!!

推荐答案

要在此处显示的UITableView存在于情节提要上，并与UITableViewController关联.

The UITableView to be shown here is present on the storyboard and associated to a UITableViewController.

在这种情况下，您正在做的事情完全是非法的，这就是为什么它不起作用的原因.您不能只调用instantiateViewControllerWithIdentifier，获取视图控制器的视图以及使用addSubview将视图填充到界面中.

In that case, what you're doing is totally illegal and that's why it isn't working. You cannot just call instantiateViewControllerWithIdentifier, grab the view controller's view, and stuff that view into the interface with addSubview.

毕竟，请考虑一下:如果这样做，视图控制器会发生什么?它已经不存在了，并且您拥有完全不起作用的视图.

After all, think about it: if you do that, what happens to the view controller? It goes out of existence, and you've got a totally nonfunctional view.

为了使TableController成为self的子视图控制器(当前的视图控制器，您必须执行一次严格的舞蹈，并且您没有在做舞蹈.

There is a rigorous dance that you are required to do in order to make the TableController a child view controller of self (the current view controller — and you are not doing the dance.
