滑动单元格时，有没有办法从 tableViewCell 导航到另一个视图控制器? [英] Is there a way to navigate from a tableViewCell to another view controller when a cell is swiped?

问题描述

所以这是我制作滑动单元格的方法:自定义表格视图单元格不滑动.无论如何，我想知道当单元格向左滑动时是否有办法从表格视图转换到另一个视图控制器.我知道当点击单元格并在 didSelectRowAtIndexPath 中调用 performSegueWithIdentifier 时可以完成它，但从未见过滑动单元格的示例.我尝试将 self.performSegueWithIdentifier("detail", sender: self) 添加到滑动的逻辑

So here's how I made my swiping cells: Custom Table View Cell Not Swiping. Anyway I was wondering if there was a way of transitioning from a table view to another view controller when a cell is swiped leftwards. I know it can be done when a cell is tapped and calling performSegueWithIdentifier in didSelectRowAtIndexPath but have never seen an example of when a cell is swiped. I tried adding self.performSegueWithIdentifier("detail", sender: self) to the logic of the swipe

if recognizer.state == .Ended {
            // the frame this cell had before user dragged it
            let originalFrame = CGRect(x: 0, y: frame.origin.y,
                width: bounds.size.width, height: bounds.size.height)
            if !reserveOnDragRelease {
                // if the item is not being deleted, snap back to the original location
                UIView.animateWithDuration(0.2, animations: {self.frame = originalFrame})
            } else {
                UIView.animateWithDuration(0.2, animations: {self.frame = CGRectMake(-self.bounds.size.width, originalFrame.origin.y, originalFrame.width, originalFrame.height)})
            // Added it here 

            }
        }

但得到的错误是 CustomTableViewCell 没有名为 performSegueWithIdentifier 的成员.任何人都有任何见解?谢谢！

but got the error that the CustomTableViewCell does not have a member named performSegueWithIdentifier. Anyone have any insight? Thanks!

推荐答案

首先，performSegueWithIdentifier 是一个 UIViewController 方法，所以是一个 UIView 对象将永远无法收到它.

First, performSegueWithIdentifier is a UIViewController method, so a UIView object will never be able to receive it.

第二，我不建议你在滑动的同时切换View Controller，因为这有点违反iOS人机界面原则.人们习惯于通过滑动来删除或编辑它，而不是导航到下一个视图控制器.

Second, I don't recommend you to do switch View Controller while swipping, because it is kind of violation to iOS human-machine interface principles. People get used to swipe to delete or edit it, not navigating to next view controller.

但是如果您真的确定要这样做，只需获取当前的 UIViewController 对象即可.但是我认为在视图中获取视图控制器对象并不是一个好的设计.您可能想查看 UITableViewDelegate 协议以找到更好的位置.此外，您还可以利用滑动手势的委托来执行操作.

But If you are really sure you want to do this, simply get your current UIViewController object and you are good to go. But getting view controller object inside a view is not a good design I think. You probably want to take a look at the UITableViewDelegate protocol to find a better place. Also, you could leverage your swipe gesture's delegate to do your actions.

你不必坚持使用performSegueWithIdentifier，有很多方法可以切换视图控制器.

You don't necesarrily to insist using performSegueWithIdentifier, there are lots of ways to switch view controllers.
