Question

Basically, every time I enter something in my textfield and save it to the table, the previous entry will be replaced by the new one. How do I add elements in a mutable array and save the last entry? I tried

[tabledata addObject....

and in the entry

tabledata.lastObject objectAtIndex...

but that didn’t work.

here is what I have:

 -(void)viewDidLoad
{
    [super viewDidLoad];

    titlestring = [[NSUserDefaults standardUserDefaults] objectForKey:@"titlehomework" ];
    detailsstring = [[NSUserDefaults standardUserDefaults] objectForKey:@"detailshomework"];

    tabledata = [[NSMutableArray alloc] initWithObjects:titlestring, nil];

    tablesubtitles = [[NSMutableArray alloc] initWithObjects:detailsstring, nil];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
    return [tabledata count];
}


-(UITableViewCell *)tableView:(UITableView *)tableView  cellForRowAtIndexPath:(NSIndexPath  *)indexPath;
{
    UITableViewCell *cell = nil;

    cell = [tableView dequeueReusableCellWithIdentifier:@"homeworkcell"];

    if(cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle   reuseIdentifier:@"homeworkcell"];
    }
    cell.textLabel.text = [tabledata objectAtIndex:indexPath.row];
    cell.detailTextLabel.text = [tablesubtitles objectAtIndex:indexPath.row];
    cell.textLabel.font = [UIFont systemFontOfSize:14.0];
    cell.textLabel.backgroundColor = [ UIColor clearColor ];
    cell.detailTextLabel.backgroundColor = [UIColor clearColor];

    //-----------------------------------------START----------------------------Set image of   cell----
    cellImage = [UIImage imageNamed:@"checkboxblank.png"];
    cell.imageView.image = cellImage;
   //--------------------------------------------END---------------------------end set image of cell--  

    return cell;
}

Without seeing more code, the best I can do is suggest something like this

[tabledata addObject:newTitle];
[tablesubtitles addObject:newSubtitle];
[tableView reloadData];

This assumes both newTitle and newSubtitle are the NSStrings you wish to add and that tableView is the pointer to the UITableView.
