swift - UICollectionView viewForSupplementaryElementOfKind didSelect

Question

如何识别 viewForSupplementaryElementOfKind 中的选择？我尝试将目标添加到 header 内的按钮，但这不起作用。选择操作是否发送到 didSelectItemAtIndexPath 还是还有其他内容？标题位于 UIStackView

内的所有元素

override func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {

    if kind == UICollectionElementKindSectionHeader {
        let cell = collectionView.dequeueReusableSupplementaryViewOfKind(UICollectionElementKindSectionHeader, withReuseIdentifier: "header", forIndexPath: indexPath) as!  mainCell
        let index = indexPath.section
        cell.btnImg.af_setBackgroundImageForState(.Normal, URL: NSURL(string: "urrl")!)
        cell.userImg.addTarget(self, action: #selector(MainController.showNextView(_:)), forControlEvents: .TouchUpInside)
        let tap = UIGestureRecognizer(target: self, action: #selector(self.test))
        cell.addGestureRecognizer(tap)
        return cell
    } else {

        return UICollectionReusableView()
    }
}

您是正确的，您需要使用 UIControl 或 UIGestureRecognizer。看起来您正在示例代码中添加两者，并且 UIGestureRecognizer 正在消耗触摸而不是按钮。
