[英]editActionsForRowAtIndexPath not executing on iOS 8 with Xcode 7
我正在3种设备上测试我的应用程序。 在iOS 9上有2台设备,在iOS 8上有1台设备。在iOS 9上, editActionsForRowAtIndexPath
函数正在工作,并且在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错误吗? 有任何想法吗 ?
谢谢 !
在iOS 8下,仅当在委托中实现commitEditingStyle调用时,editActions才启用。 在您的tableViewController中添加以下方法:
- (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
}
如果您具有自定义UITableViewCell
,并且具有GestureRecognizer
,请检查委托方法shouldRecognizeSimultaneouslyWithGestureRecognizer:
将此委托方法添加到类。
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == UITableViewCellEditingStyle.Delete {
}
}
