custom cell based on row index iphone
- by dubbeat
I'm wondering if it is possible to add cell content to a uitableview based on the row index?
For example if it is the first cell (row 0) I want to add an image and text.
If it is the second row I would like to add a button.
For all other rows I would like to just add a line of text.
I tried using indexPath.row. It worked the first time but when I scroll off of the screen and then back up my first image dissapears.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
PromoListItem *promo = [promoList objectAtIndex:indexPath.row];
static NSString *CellIdentifier = @"Cell";
AsyncImageView *asyncImageView = nil;
UILabel *label = nil;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(indexPath.row==0)
{
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
CGRect frame;
frame.origin.x = 0;
frame.origin.y = 0;
frame.size.width = 100;
frame.size.height = 100;
asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease];
asyncImageView.tag = ASYNC_IMAGE_TAG;
[cell.contentView addSubview:asyncImageView];
frame.origin.x = 110;
frame.size.width =100;
label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.tag = LABEL_TAG;
[cell.contentView addSubview:label];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
} else {
asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG];
label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG];
}
NSURL *url = [NSURL URLWithString:promo.imgurl];
[asyncImageView loadImageFromURL:url];
label.text = promo.artistname;
}else
{
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
CGRect frame;
frame.origin.x = 0;
frame.origin.y = 0;
frame.size.width = 100;
frame.size.height = 100;
//asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease];
// asyncImageView.tag = ASYNC_IMAGE_TAG;
// [cell.contentView addSubview:asyncImageView];
frame.origin.x = 110;
frame.size.width =100;
label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.tag = LABEL_TAG;
[cell.contentView addSubview:label];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
} else {
// asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG];
label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG];
}
//NSURL *url = [NSURL URLWithString:promo.imgurl];
//[asyncImageView loadImageFromURL:url];
label.text = promo.artistname;
}
return cell;
}
