从集合视图中的可重用单元格获取按钮点击(xib 文件) [英] Get button click from reusable cell in collection view (xib file)

问题描述

我创建了可重复使用的单元格，在 XIB 中包含一个用于集合的按钮.

I have created reusable cell with include a button in a XIB for a collection.

我可以在集合视图中更改标签和按钮的文本，但我无法获得点击事件.

I can change the text of labels and buttons in the collection view but i can't get on click event.

我尝试了以下选项:

一个.这在 UICollectionViewCell 中:不工作

a. This in UICollectionViewCell : Not working

class cellVC: UICollectionViewCell {
    @IBOutlet weak var sampleLabel: UILabel!
    @IBOutlet weak var buttonClicked: UIButton!

    @IBAction func buttonTest(_ sender: Any) {
        print("dsfsdf   111111")
    }
}

B.我也试过:不工作

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{

    let cell : cellVC = collectionView.dequeueReusableCell(withReuseIdentifier: "cellVC", for: indexPath) as! cellVC
    cell.sampleLabel. = "sample text"
    cell.buttonClicked.tag = indexPath.row
    cell.buttonClicked.addTarget(self, action: #selector(masterAction(sender:)), for: .touchUpInside)

    cell.buttonClicked.backgroundColor = UIColor.cyan
    return cell
}


func masterAction(_ sender: UIButton) {
    print ("button click")
}

由于两种解决方案都不起作用，我该如何实现这一点.

As both solutions are not working, how do i achieve this.

谢谢

推荐答案

当按钮链接到文件所有者而不是您的单元格时，有时会发生这种情况.

This sometimes happen when the button is linked to the File's Owner instead of your cell.

右键单击IB中的按钮并检查引用插座是否正确，这应该是您的单元格而不是文件的所有者，如下图所示:

Right click on the button in IB and check if the referencing outlet is correct, this should be your cell and not the File's Owner like in the image below:
