Table view content missing during scrolling

Question

I am using table view cell and adding a pop up view on clicking a button placed in cell .But when I am scrolling the table view view pop is disappearing from my cell. Here is my code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellF
orRowAtIndexPath:(NSIndexPath *)indexPath
{
     NSString *CellIdentifier =[NSString stringWithFormat:@"ArticleCell%d  %d",indexPath.section,indexPath.row];

    __block ArticleCell_iPad *cell = (ArticleCell_iPad *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {
        cell = [[ArticleCell_iPad alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];

        [[NSBundle mainBundle] loadNibNamed:@"SynopsysViewSharing" owner:self options:nil];

        cell = [[[ArticleCell_iPad alloc] initWithFrame:CGRectMake(0, 0, kCellWidth_iPad, kCellHeight_iPad)] autorelease];

        __block NSDictionary *currentArticle = [self.articles objectAtIndex:indexPath.section];

         [cell.iconImage loadImageWithURL:[[currentArticle objectForKey:@"sourceLogoImg"]objectForKey:@"text"]];


        [cell.sideButton setBackgroundImage:[UIImage imageNamed:[cellButtonImageArr objectAtIndex:self.selectIndex]]

        [cell.sideButton addTarget:self action:@selector(sideButtonClicked:) forControlEvents:UIControlEventTouchUpInside];

        cell.sideButton.tag = indexPath.section;

        TableViewCellSelectionStyleNone;

   }
   return cell;
}

Button Action:

 -(IBAction)sideButtonClicked:(UIButton*)sender
 {

    buttonShare=[[[NSBundle mainBundle] loadNibNamed:@"SynopsysViewSharing" owner:self options:nil] lastObject];

    NSIndexPath *myIP = [NSIndexPath indexPathForRow:0 inSection:sender.tag];
    ArticleCell_iPad *cellSelected = (ArticleCell_iPad*)[_horizontalTableView cellForRowAtIndexPath:myIP];

    [cellSelected.contentView addSubview:buttonShare];
    buttonShare.alpha = 0.0f;
    buttonShare.tag=500;
    [buttonShare setFrame:CGRectMake(0,600, cellSelected.frame.size.height,55)];

    [UIView animateWithDuration:0.5 animations:^{
    [buttonShare setFrame:CGRectMake(0,cellSelected.frame.size.width-55, cellSelected.frame.size.height,55)];
    buttonShare.alpha = 1.0f;
   } completion:^(BOOL finished) {

   }];
}

Answer 1

Instead adding the buttonshare to the contentview through coding, pls try adding your 'buttonshare' in storyboard for the prototype cell itself and make it hidden by checking the hidden property.

And tap on for your button in the UITableviewCell make the hidden property of buttonshare to "NO" in sideButtonClicked:

Hope it helps :)
