Stop reloading of table data in UITableView when it pulls/scrolls - iphone

Question

I know it is not general practice to do this but my application need this functionality. I am very new to iPhone programming. When the user pulls/scrolls the table screen it gets updated I have to stop it. Also order of the data get changed when I pull it.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 300, 50)];
[button addTarget:self action:#selector(optionButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:optionValue forState:UIControlStateNormal];
[button setTag:indexPath.row];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell.contentView addSubview:button];
[button release];
}
return cell;
}

Answer 1

First, the way you are using cellForRowAtIndexPath is wrong.
static NSString *MyIdentifier = #"MyIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 300, 50)];
[button addTarget:self action:#selector(optionButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[cell.contentView addSubview:button];
[button release];
}
//These should be outside of the cell == nil loop so that they get refreshed correctly
[button setTitle:optionValue forState:UIControlStateNormal];
[button setTag:indexPath.row];
return cell;
Secondly, I don't see where you set optionValue, but if you don't want to hit the database every time, then store the values in an NSArray and get the values from the array. This way you only hit the database once when you load the view.
