Question

I have been trying to fix this problem for hours. My app keeps crashing when I try to scroll. I looked in to the reusable section but am still stuck.

UPDATE: I am running xcode 4.2 with ARC & I am having bad access error.

UPDATE 2: I tried to locate the problem using Zombies but am still unable to fix the issue.

UPDATE 3 [problem solved]: I made sure all outlets were [self set___:nil] in the ViewDidUnload. I also created a property for the added view instead of creating the view in the .m file.
THe comment at the bottom here helped me out too:
get "EXC_BAD_ACCESS" when trying dismissModalViewController after parent view controller has been viewDidUnload

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [self.sortedKeys count];
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    return [self.sortedKeys objectAtIndex:section];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    listData2 =[self.tableContents objectForKey:
    [self.sortedKeys objectAtIndex:section]];
    return [listData2 count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    questionTitle = [[self.tableContents objectForKey:[self.sortedKeys objectAtIndex: [indexPath section]]] objectAtIndex:[indexPath row]];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Foobar"];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Foobar"];
        cell.selectionStyle = UITableViewCellSelectionStyleBlue;
        cell.textLabel.textColor = [UIColor blueColor];
    }

    cell.textLabel.text = questionTitle;

    return cell;
}

Answer 1

Rather than setting questionTitle in your cellForRowAtIndexPath which is (presumably) a property of your ViewController, define a local string:

NSString *questionTitle2 = ...

and then use that to set the cell label:

cell.textLabel.text = questionTitle2;

Does that make any difference?
