ios - 从 UITableViewCell 调用 UIButton 操作

Question

我在 UITableviewCell 类中动态创建了几个按钮，如下所示:

for (clientObjectId, _) in connectedObjectIds {
    self.clientNameButton = UIButton(type: UIButtonType.System) as UIButton
    self.clientNameButton.titleLabel?.lineBreakMode = NSLineBreakMode.ByTruncatingTail
    self.clientNameButton.frame = CGRectMake(self.leftSideSpaceForUsersAndUserLabel, clientNameButtonFrameHeight, self.nameButtonWidth, self.nameButtonHeight)
    self.clientNameButton.setTitle(self.userObjectIdsAndNames[clientObjectId], forState: UIControlState.Normal)
    self.clientNameButton.titleLabel!.font = UIFont(name: "Helvetica", size: 12.0)
    self.clientNameButton.addTarget(self, action: "asdf:", forControlEvents: UIControlEvents.TouchUpInside)
    self.nameButtons.append(self.clientNameButton)
    self.addSubview(self.clientNameButton)
}

但是，我似乎找不到在 TableView 单元格类中调用以下函数的方法:

func asdf(sender:UIButton) {
     print("Button tapped")
}

我并不真正关心能够在 UITableViewCell 类中调用它，而是关心在 TableView 类中调用该函数。

有人能解决这个问题吗？

    self.clientNameButton.setTitle(self.userObjectIdsAndNames[clientObjectId], forState: UIControlState.Normal)
    self.clientNameButton.titleLabel!.font = UIFont(name: "Helvetica", size: 12.0)
    self.clientNameButton.addTarget(self, action: "asdf:", forControlEvents: UIControlEvents.TouchUpInside)
    self.nameButtons.append(self.clientNameButton)
    self.addSubview(self.clientNameButton)
