UITableViewCell - 无法识别的选择器发送到实例

Question

我正在尝试向右滑动但是却出现了这个错误：

  

由于未捕获的异常而终止应用   'NSInvalidArgumentException'，原因：' - [UITableViewCell   setDelegate]：无法识别的选择器发送到实例0x7fbadb85d710'

这条线的错误：

cell.delegate = self;
cell.allowsMultipleSwipe = allowMultipleSwipe;
cell.rightSwipeSettings.transition = data.transition;
cell.rightExpansion.buttonIndex = data.rightExpandableIndex;
cell.rightExpansion.fillOnTrigger = YES;
cell.rightButtons = [self createRightButtons:data.rightButtonsCount];

我的代码：

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
     {
         MGSwipeTableCell *cell ;
         static NSString * reuseIdentifier = @"listAlbuns";
         cell = [self.tblAlbum dequeueReusableCellWithIdentifier:reuseIdentifier];
         if (!cell) {
             cell = [[MGSwipeTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
         }

         NSString *sectionTitle = [albumSectionTitles objectAtIndex:indexPath.section];
         NSMutableDictionary *sectionAlbuns = [albuns objectForKey:sectionTitle];
         NSString *title = [sectionAlbuns objectForKey: [NSString stringWithFormat:@"%i", indexPath.row]];
         NSMutableDictionary *album = [baseController getCurrentItemByTitle: albunsBD :title];

         TestData *data = [tests objectAtIndex:indexPath.row];
         NSInteger ID = [album objectForKey: @"1"];
         cell.textLabel.text = [album objectForKey: @"2"];
         cell.detailTextLabel.text = [[albumDAO selectArtistByAlbumID: ID] uppercaseString];
         cell.imageView.image = [UIImage imageNamed: @"icones-categorias-album"];
         cell.imageView.image = [albumDAO getThumb: ID];

         cell.tag = [album objectForKey: @"1"];
         cell.delegate = self;
         cell.allowsMultipleSwipe = allowMultipleSwipe;
         cell.rightSwipeSettings.transition = data.transition;
         cell.rightExpansion.buttonIndex = data.rightExpandableIndex;
         cell.rightExpansion.fillOnTrigger = YES;
         cell.rightButtons = [self createRightButtons:data.rightButtonsCount];

         return cell;
     }

任何人都知道可能是什么？
