Question

我正在尝试从特定单元格的子视图中触发UITapGesture时从单元格中检索数据。我现在的代码为每个代码返回了错误的单元格，我无法告诉它是如何解决的。有时它会改变同一个细胞。

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "followerSeg" || segue.identifier == "followingSeg") {
        let vc = segue.destinationViewController as! FollowersFollowingVC
        let x = sender as! UITapGestureRecognizer
        let view = x.view!
        let cellone = view.superview as UIView?
        let cell = cellone?.superview as! PersonCell
        vc.userName = cell.person.profileName
        vc.userId = cell.person.id
        vc.segStatus = segue.identifier == "followerSeg" ? 0 : 1
    }
}

您可能想尝试使用UITableView的indexPathForRowAtPoint方法。我已经和objc / iOS合作了5年多，但这是我在Swift的第一次拍摄。请原谅任何语法错误。

假设您有一个名为tableView的属性，代码如下：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "followerSeg" || segue.identifier == "followingSeg") {
        let vc = segue.destinationViewController as! FollowersFollowingVC
        let x = sender as! UITapGestureRecognizer
        let location = x.locationInView(self.tableView) as CGPoint
        let indexPath = self.tableView.indexPathForRowAtPoint(location) as NSIndexPath?
        let cell = self.tableView.cellForRowAtIndexPath(indexPath!) as! PersonCell
        vc.userName = cell.person.profileName
        vc.userId = cell.person.id
        vc.segStatus = segue.identifier == "followerSeg" ? 0 : 1
    }
}

触发UITapGesture时，从单元的子视图内获取单元格的引用
