Question

I add UIView with background image(that has transparent parts) into the UITableViewCell. At first everything looks perfect, but after deselecting row, background of my UIView looses transparency.

static NSString *CellIdentifier = @"Cell";

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

UIView *priceView = [[UIView alloc] init];
priceView.frame = CGRectMake(250, 10, 40, 21);

priceView.backgroundColor = [UIColor colorWithPatternImage:[ UIImage imageNamed:@"priceBG.png" ]];
priceView.opaque = NO;
[priceView.layer setOpaque:NO];
[cell addSubview:priceView];
[priceView release];
return cell;

Answer 1

Use a UIImageView instead and add it to the cell’s contentView:

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

UIImageView *priceImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"priceBG.png" ]];
priceImageView.frame = CGRectMake(250, 10, 40, 21);
priceImageView.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:priceImageView];
[priceImageView release];    
return cell;
