Cant display button on specific rows of UITableView properly for iPhone
- by varunwg
Hi,
I am trying to have a button for selected rows of my table.
Here is the example code I am using:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *ControlRowIdentifier = @"ControlRowIdentifier";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:ControlRowIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:ControlRowIdentifier] autorelease];
}
if ([indexPath row] > 5) {
UIImage *buttonUpImage = [UIImage imageNamed:@"button_up.png"];
UIImage *buttonDownImage = [UIImage imageNamed:@"button_down.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0, 0.0, buttonUpImage.size.width, buttonUpImage.size.height);
[button setBackgroundImage:buttonUpImage forState:UIControlStateNormal];
[button setBackgroundImage:buttonDownImage forState:UIControlStateHighlighted];
[button setTitle:@"Tap" forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = button;
}
NSUInteger row = [indexPath row];
NSString *rowTitle = [list objectAtIndex:row];
cell.textLabel.text = rowTitle;
return cell;
}
This code works absolutely fine when loaded for 1st time. So, as per the logic it shows 'Tap' button for all rows greater than 5.
Problem occurs when I scroll up and down. Once I do that it just starts putting that button at any random row. I dont understand why it does that and it'll be really helpful if someone can give some tips on this.
Thanks.
