editActionsForRowAtIndexPath 未在 iOS 8 和 Xcode 7 上执行

editActionsForRowAtIndexPath not executing on iOS 8 with Xcode 7

我正在 3 台设备上测试我的应用程序。 iOS 9 上有 2 台设备,iOS 8 上有一台设备。在 iOS 9 上,功能 editActionsForRowAtIndexPath 正在运行,当我滑动一个单元格时会显示操作。但是在 iOS 8 上,我无法滑动单元格。

这是我的代码:

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
    let ShareAction = UITableViewRowAction(style: .Normal, title: "Partager", handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) -> Void in
        if AllArticle[indexPath.row].Title != nil && AllArticle[indexPath.row].Link != nil {
            var ToShare = []
            if self.search {
                ToShare = [ArticleFiltered[indexPath.row].Link!]
            } else {
                ToShare = [AllArticle[indexPath.row].Link!]
            }
            let ActivityViewController = UIActivityViewController(activityItems: ToShare as [AnyObject], applicationActivities: nil)
            self.presentViewController(ActivityViewController, animated: true, completion: {
                self.TableView.setEditing(false, animated: true)
            })
        }
    })

    let FavoriteAction = UITableViewRowAction(style: .Normal, title: "Ajouté aux favoris", handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) -> Void in

        if AllArticle[indexPath.row].Favoris {
            let alreadyInView = UIAlertController(title: "Favori déjà ajouté", message: "Cet article fait déjà parti de vos favoris", preferredStyle: .Alert)
            let ActionAlert = UIAlertAction(title: "Ok", style: .Default) { (action) in }
            alreadyInView.addAction(ActionAlert)
            self.presentViewController(alreadyInView, animated: true, completion: nil)
        } else {
            AllArticle[indexPath.row].Favoris = true
            let alreadyInView = UIAlertController(title: "Favori ajouté", message: "Cet article fait maintenant parti de vos favoris", preferredStyle: .Alert)
            let ActionAlert = UIAlertAction(title: "Ok", style: .Default) { (action) in }
            alreadyInView.addAction(ActionAlert)
            self.presentViewController(alreadyInView, animated: true, completion: nil)
            Favorite.append(indexPath.row)
            saveFavoris()
        }
        self.TableView.setEditing(false, animated: true)
    })

    FavoriteAction.backgroundColor = UIColor.redColor()

    return [ShareAction, FavoriteAction]
}

当然我添加了

ViewDidLoad()

if TableView != nil {
        TableView.delegate = self
        TableView.dataSource = self
        TableView.tableFooterView = UIView(frame: CGRectZero)
        TableView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "tapTableView"))
        TableView.gestureRecognizers?.last?.delegate = self
    }

可能是 Xcode 错误? 有什么想法吗?

谢谢!

Under iOS 8 editActions 仅当在您的委托中实现 commitEditingStyle 调用时才启用。在您的 tableViewController 中添加波纹管方法:

- (void)tableView:(UITableView*)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath*)indexPath
{
    // All tasks are handled by blocks defined in editActionsForRowAtIndexPath, however iOS8 requires this method to enable editing
}

如果您有自定义 UITableViewCell,并且有 GestureRecognizer,请检查委托方法 - shouldRecognizeSimultaneouslyWithGestureRecognizer:

将此委托方法添加到 class。

  func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == UITableViewCellEditingStyle.Delete {
    }
}
