Swift - 将手势识别器添加到表格单元格中的对象 [英] Swift - add gesture recognizer to object in table cell

问题描述

我正在尝试向表格视图单元格中的对象（特别是图像）添加手势识别器。现在，我对手势识别器很熟悉，但是对于如何设置这个问题我感到有些困惑。实际的表格单元格没有viewDidLoad方法，所以我认为我不能在那里声明手势识别器。

I'm attempting to add a gesture recognizer to an object (an image, specifically) in a table view cell. Now, I'm familiar with gesture recognizers, but am left slightly confused as to how to set this up. The actual table cell doesn't have a viewDidLoad method, so I don't think I can declare the gesture recognizer there.

这个问题（ UIGestureRecognizer和UITableViewCell问题）似乎是相关的，但答案是在客观C中，不幸的是我只是流利的。

This question (UIGestureRecognizer and UITableViewCell issue ) seems to be related, however the answer is in objective C, and unfortunately I'm only fluent in swift.

如果有人可以帮我解决如何向表格单元格中的对象添加手势识别器（不是整个桌面视图），甚至可能帮助我将上述链接的答案翻译成swift，我将不胜感激

If anybody could perhaps help me out on how I'd go about adding a gesture recognizer to an object in a table cell (NOT the whole tableview), or even perhaps aid me in translating the answer from the above link to swift, I'd be grateful

推荐答案

这里是一个快速的Swift翻译链接帖子的解决方案，将滑动手势识别器添加到UITableView，然后确定滑动发生在哪个单元格：

Here's a quick Swift-translation of the linked post's solution, adding the swipe gesture recognizer to the UITableView and then determining which cell the swipe happened on:

class MyViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        var recognizer = UISwipeGestureRecognizer(target: self, action: "didSwipe")
        self.tableView.addGestureRecognizer(recognizer)
    }

    func didSwipe(recognizer: UIGestureRecognizer) {
        if recognizer.state == UIGestureRecognizerState.Ended {
            let swipeLocation = recognizer.locationInView(self.tableView)
            if let swipedIndexPath = tableView.indexPathForRowAtPoint(swipeLocation) {
                if let swipedCell = self.tableView.cellForRowAtIndexPath(swipedIndexPath) {
                    // Swipe happened. Do stuff!
                }
            }
        }
    }

}
