自定义UITableViewCell为零

Question

I am using xib to load the cell in the UITableViewController . There is a button on the cell by hitting which a modal pops up and when we hit something on that modal, I want to change the image in the cell. But I am not able to get the cell even if I am passing the indexPath. I have used following code:

    NSIndexPath* indexPath1 = [NSIndexPath indexPathForRow:sender inSection:0];
    [self.tableView2 reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath1, nil] withRowAnimation:UITableViewRowAnimationNone];

I have written the code in the cellForRowAtIndexPath as follows:

    if([[feedbackDictionary objectForKey:[NSString stringWithFormat:@"Key%li",indexPath.row]] isEqualToString:[NSString stringWithFormat:@"%li",indexPath.row]])

            {
                NSLog(@"Yay! Feedback");
                cell.checkmark.image=[UIImage imageNamed:@"tick"];
            }
            else
            {
                NSLog(@"Oops! No feedback");
                cell.checkmark.image=[UIImage imageNamed:@"orangetick"];
            }

I am supposing that when reloadrows will run,it will reload that particular cell by calling cellForRowAtIndexPath . But it is of no help. The image is not changing at all.

Secondly, I tried to get the cell by using following

    NSIndexPath *ip=[NSIndexPath indexPathForItem:button.tag inSection:0];
    ExpandingCell *cell=(ExpandingCell*) [_tableView2 cellForRowAtIndexPath:ip];
    if(cell==nil)
    {
     NSLog(@"No cell");
    }

I am getting no cell as output. Please help.

Answer 1

At first, to debug it try to call [self.tableView2 reloadData] . If your image is changed, it means that you were called wrong indexPath for reloadRowsAtIndexPaths method. Also button.tag could return wrong tag, because cells are reusable in UITableView, and it can be cell that already used before.

Answer 2

I have found the problem and fixed it. The problem was when modal pops up,it was loosing control over the view controller and that is why tableview is null and nothing was changed.
