如何在集合视图单元格中添加 uibutton 操作? [英] How to add uibutton action in a collection view cell?

问题描述

所以我有这个集合视图，其中包含位于右上角的编辑按钮的单元格.如何将动作连接到其中?

So I have this collection view with cells containing an edit button, located on the upper right corner. How do I wire up an action into it?

我尝试在 collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) 中添加 cell.editbutton.addTarget ->UICollectionViewCell 但是没有检测到 touchUpInside 事件.

I tried adding cell.editbutton.addTarget in collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell But it doesn't detect the touchUpInside Event.

推荐答案

你可能需要-

在cellForItemAtIndexPath

Swift 2.X

let editButton = UIButton(frame: CGRectMake(0, 20, 40,40))
editButton.setImage(UIImage(named: "editButton.png"), forState: UIControlState.Normal)
editButton.addTarget(self, action: #selector(editButtonTapped), forControlEvents: UIControlEvents.TouchUpInside)

cell.addSubview(editButton)

Swift 3.X

let editButton = UIButton(frame: CGRect(x:0, y:20, width:40,height:40))
editButton.setImage(UIImage(named: "editButton.png"), for: UIControlState.normal)
editButton.addTarget(self, action: #selector(editButtonTapped), for: UIControlEvents.touchUpInside)

cell.addSubview(editButton)

并执行您的操作-

override func viewDidLoad() {
       super.viewDidLoad()
}

@IBAction func editButtonTapped() -> Void {
    print("Hello Edit Button")
}
