func buttonAction(sender: UIButton){

Add action for button from <code>tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)</code> method from your viewController.

<pre><code>cell.btn.tag = indexPath.row;

cell.btn.addTarget(self, action:#selector(handleButtonClicked(_:)), for: .touchUpInside).

In your cell define a protocol:

<pre><code>protocol MyCellDelegate: class {
 func buttonTapped()
}
</code></pre>

and define a delegate variable:

<pre><code>weak var delegate: MyCellDelegate?
</code></pre>

Make your <code>viewController</code> conform to the defined protocol.

When creating the cell in the <code>viewController</code>, assign it the delegate:

<pre><code>cell.delegate = self
</code></pre>

When the button in the cell is tapped, send the delegate appropriate message:

<pre><code>delegate?.buttonTapped()
</code></pre>

In your <code>viewController</code> implement the method:

<pre><code>func buttonTapped() {
 //do whatever you need
}
</code></pre>

You can pass as an argument the cell's index, so the <code>viewController</code> knows which cell button was tapped.

entityMap|blocks|key|c9l4h|text|首先，您应该编写一个协议，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|a2ol3|protocol+CustomCellDelegate+{
++func+doAnyAction(cell:CustomUITableViewCell)
}|code-block|syntax|javascript|5daud|然后在您的自定义单元格类中声明：|aps7u|weak+var+delegate:CustomCellDelegate?|bm5uk|在自定义单元格类中的IBAction中：|7k825|@IBAction+func+onButtonTapped(_+sender:+UIButton)+{

}|a9br8|现在在您的viewController中：|973j2|1-让你的视图控制器实现CustomCellDelegate。2-在你的cellForRow中声明单元格时，不要忘了写：|48n41|cell.delegate+=+self|9trn8|3-最后在视图控制器中调用函数：|a5jc2|func+doAnyAction(cell:+CustomUITableViewCell)+{

First of all you should write a protocol for example:

<pre><code>protocol CustomCellDelegate {
 func doAnyAction(cell:CustomUITableViewCell)
}
</code></pre>

Then inside your custom cell class declare:

<pre><code>weak var delegate:CustomCellDelegate?
</code></pre>

and inside your IBAction in the custom cell class:

<pre><code>@IBAction func onButtonTapped(_ sender: UIButton) {
 delegate?.doAnyAction(cell: self)
 //here we say that the responsible class for this action is the one that implements this delegate and we pass the custom cell to it.
}
</code></pre>

Now in your viewController:

1- Make your view controller implement CustomCellDelegate.
2- In your cellForRow when declaring the cell don't forget to write:

<pre><code>cell.delegate = self
</code></pre>

3- Finally call the function in your viewcontroller:

<pre><code>func doAnyAction(cell: CustomUITableViewCell) {
 let row = cell.indexPath(for: cell)?.row
 //do whatever you want

 }
}
</code></pre>

entityMap|blocks|key|m6va|text|你可以使用委托模式。创建自定义协议。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|10m04|protocol+CustomTableViewCellDelegate+{

You can use delegate pattern. Create a custom protocol.

<pre><code>protocol CustomTableViewCellDelegate {
func buttonTapped() }
</code></pre>

and on tableview cell conform delegate

<pre><code>class CustomTableViewCell: UITableViewCell {
var delegate: CustomTableViewCellDelegate!

@IBAction func buttonTapped(_ sender: UIButton) {
 delegate.buttonTapped()
} }
</code></pre>

table view data source

<pre><code>func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier", for: indexPath) as! CustomTableViewCell
 cell.delegate = self
 return cell
}
</code></pre>

conform protocol(delegate) from table view controller or view controller

<pre><code>extension TestViewController: CustomTableViewCellDelegate {
func buttonTapped() {
 print("do something...")
} }
</code></pre>

I have a custom cell that has a xib, this cell contains a button, when the button is pressed I want to do an action , but not inside my custom cell class but from inside the viewcontroller that contains the tableview of the custom cell, any help please?

 我有一个自定义单元格，它有一个xib，这个单元格包含一个按钮，当按钮被按下时，我想做一个动作，但不是在我的自定义单元格类中，而是从包含自定义单元格的表格视图的视图控制器中，有什么帮助吗？
