在 UITapGestureRecognizer 上添加参数

Question

我想问一下如何在我的 UILabel 上的 UITapGestureRecognizer 上添加参数。到目前为止，这是我得到的：

self.feedSource.text = source_link
                    self.feedSource.userInteractionEnabled = true
                    let feedSourceTapGesture = UITapGestureRecognizer(target: self, action: Selector("openLinkFromFeedSource"))
                    self.feedSource.addGestureRecognizer(feedSourceTapGesture)


func openLinkFromFeedSource() {
        print("tapped")
    }

我想要实现的是当我点击标签时，我可以从 openLinkFromFeedSource 获取 self.feedSource.text 的值

谢谢！

Answer 1

你应该从这样的点击手势动作中得到这个：

func didTapOnView(tap: UITapGestureRecognizer) {
    let label = tap.view
    // do with that label
}

Answer 2

试试这个

self.feedSource.userInteractionEnabled = true
let feedSourceTapGesture = UITapGestureRecognizer(target: self, action: Selector("openLinkFromFeedSource:"))
self.feedSource.addGestureRecognizer(feedSourceTapGesture)


func openLinkFromFeedSource(sender: UITapGestureRecognizer) {
  let label = sender.view

    print("tapped")
}
