blocks|key|23912|text|此外，将tableFooterView设置为UIView()会删除行的原因是，您将为该属性设置一个空的UIView()对象。根据Apple文档：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|23913|var+tableFooterView:+UIView?|code-block|syntax|javascript|23914|因此，设置一个空的UIView()将不会在此属性的数据下显示任何内容。|23915|您可以通过将tableFooterView重置为默认值来恢复空行，如下所示：|23916|tableView.tableFooterView+=+nil|23917|entityMap^0|4|F|M|8|1F|8|0|0|0|6|F|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|11|8|@$9|12|A|13|B|C]]|D|@]|E|$]]|$1|O|3|P|5|H|7|14|8|@]|D|@]|E|$I|J]]|$1|Q|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|R|$]]

To add to this, the reason why setting <code>tableFooterView</code> to <code>UIView()</code> removes the rows is because you are setting an empty <code>UIView()</code> object to the property. As per the Apple documentation:

<pre><code>var tableFooterView: UIView?
</code></pre>

Therefore setting an empty UIView() will display nothing below your data for this property.

You can bring the empty rows back by resetting <code>tableFooterView</code> to the default value, like so:

<pre><code>tableView.tableFooterView = nil
</code></pre>

Setting the <code>tableFooterView</code> should remove extra cell like views.

 }
</code></pre>

Call this code in <code>viewDidLoad</code> method.

blocks|key|4531487|text|您也可以在情节提要中实现这一点，只需将视图拖动到表视图的页脚区域，然后使用属性检查器将其高度和背景颜色分别设置为1和透明。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4531488|(这假设您出于某种原因不能或不想只使用Group+style设置。否则，就这么做吧。)|4531489|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can achieve this also in Storyboard by simply dragging a view into the table view's footer area, and then set its height and background color to 1 and clear respectively using the property inspector.

(This assumes that you either can't or don't want to just use the Group style setting for some reason. Otherwise, just do that.)

blocks|key|4531713|text|如果你想删除应用程序中所有UITableViews的行，只需像这样添加一个扩展：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4531714|Swift+5.0|4531715|extension+UITableView+{

if you want to remove rows for all <code>UITableViews</code> in your app, just add an extension like this:
Swift 5.0
<pre><code>extension UITableView {

override open func didMoveToSuperview() {
 super.didMoveToSuperview()
 self.tableFooterView = UIView()

}

Simply add:

<pre><code>tableView.tableFooterView = UIView()
</code></pre>

Explanation:

This is totally valid and works perfectly in swift 3.By Since you are setting an empty UIView() object to the property, Setting tableFooterView to UIView() removes the rows.

blocks|key|24129|text|我是对的。我们可以通过添加|type|unstyled|depth|inlineStyleRanges|entityRanges|data|24130|tableView.tableFooterView+=+UIView()+//+to+remove+extra+cells+in+tableView|code-block|syntax|javascript|24131|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Abobe anwer is right. We can achieve this by adding

<pre><code>tableView.tableFooterView = UIView() // to remove extra cells in tableView
</code></pre>

blocks|key|24115|text|我尝试了tableview.tableFooterView+=+UIView()，但它对我不起作用。我使用的是一个自定义的TableViewViewCell，也许这就是原因。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|24116|我确实找到了一个黑客。在我的函数numberOfRowsInSection中|24117|func+tableView(_+tableView:+UITableView,+numberOfRowsInSection+section:+Int)+->+Int+{
++++return+yourArrayClass.count+-+1
}|code-block|syntax|javascript|24118|这使得我额外的空白自定义UITableViewCell不再显示。当然是额外的空白。我将通过添加更多的单元来测试它。作为参考，我在cellForRowAt函数中使用了Swift+3，Firebase，一个自定义单元格类。|24119|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I tried the tableview.tableFooterView = UIView() and it did not work for me. I am using a custom TableViewViewCell, perhaps that is why. 

I did find a hack tho. In my func numberOfRowsInSection 

<pre><code>func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
 return yourArrayClass.count - 1
}
</code></pre>

And that makes my extra blank custom UITableViewCell not display anymore. Of course its the extra blank one. I will test it some more by adding more Cells. For reference, I am using Swift 3, Firebase, a custom cell class, inside the cellForRowAt function.

Hi I have a <code>TableViewController</code> with two static cells, however when displayed, it shows the two static cells, and then all the other empty cells for the tableview. However I don't want to display those cells as they are useless. How do I hide the rest of the cells apart from the two static cell?

您好，我有一个包含两个静态单元格的TableViewController，但是当显示时，它会显示两个静态单元格，然后显示表视图的所有其他空单元格。但是，我不想显示这些单元，因为它们是无用的。如何隐藏除两个静态单元格之外的其余单元格？
