Question

I have a TableView which has 2 sections and the 2nd section is only shown when the 3rd row in the first section is selected. Only the first section has images. Everything is working fine. The 3rd row in the 2nd section shows a TextField and a button when selected and you can save a date in there via pressing the finish button. Works also fine. You can select that row and go to other rows and everything is normal. If though, you tap into the TextField and don’t save the input or don’t write anything, then it bugs.
It will reload the table with images at random rows it seems.
I thought it’s the keyboard which pops up, so I tried to manually dismiss it. Bug is still there.
I am really curious why this happens, so I am hoping for help! Thanks in advance!!

My cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    // Configure the cell...

    BOOL tooltipValue = [[NSUserDefaults standardUserDefaults] boolForKey:@"tooltipSetting"];
    BOOL compactSettingValue = [[NSUserDefaults standardUserDefaults] boolForKey:@"compactModeSetting"];

   NSDictionary *dictionary = [self.settingsArray objectAtIndex:indexPath.section];
   NSArray *array = [dictionary objectForKey:@"Items"];
   NSString *cellValue = [array objectAtIndex:indexPath.row];
   cell.textLabel.text = cellValue;

   if (indexPath.section == 0 && self.iconSetCount < 3) {
        NSDictionary *imagedictionary = [self.imagesArray objectAtIndex:indexPath.section];
        UIImage *cellImage = [[imagedictionary objectForKey:@"images"] objectAtIndex:indexPath.row];
        cell.imageView.image = cellImage;
        self.iconSetCount++;
        NSLog(@"%d",self.iconSetCount);
    }


    if (indexPath.section == 0){

                        [self.button setTitle:NSLocalizedString(@"done", @"") forState:UIControlStateNormal];

Answer 1

The cell identifier is abused here. Removing the cell identifier would be the quickest solution here, reallocating the cells every time.
Rewriting the code to include the cell identifier would make it more robust.
