Subview of UITableViewcell disappear when UItableViewcell is highlighted,anyway to fix it? - ios

Question

I'm working with RESIDEMENU,and trying to add a line between cells of LeftMenuViewController,here is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:21];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.highlightedTextColor = [UIColor lightGrayColor];
cell.selectedBackgroundView = [[UIView alloc] init];
}
NSArray *titles = #[#"Home", #"Calendar", #"Profile", #"Settings", #"Log Out"];
NSArray *images = #[#"IconHome", #"IconCalendar", #"IconProfile", #"IconSettings", #"IconEmpty"];
cell.textLabel.text = titles[indexPath.row];
cell.imageView.image = [UIImage imageNamed:images[indexPath.row]];
UIView * lineView= [[UIView alloc]initWithFrame:CGRectMake(10, 0, cell.contentView.bounds.size.width, 3)];
lineView.backgroundColor=[UIColor redColor];
[cell.contentView addSubview:lineView];
return cell;
}
I can see these lines at first, but when I touch any cell, the cell is highlighted ,and the line of this cell disappear weirdly.any way to fix it?

Answer 1

UITableViewCell changes the background color of all sub views when cell is selected or highlighted.
You have three options :
No selection style
cell.selectionStyle = UITableViewCellSelectionStyleNone;
Subclass UITableViewCell and overriding Tableview cell's setSelected:animated and/or setHighlighted:animated
Add the line as a layer
CALayer* layer = [CALayer layer];
layer.frame = CGRectMake(10, 0, cell.contentView.bounds.size.width, 3);
layer.backgroundColor = [UIColor redColor].CGColor;
[cell.contentView.layer addSublayer:layer];

Another workaround is overwriting setBackgroundColor: and expose similar method to change its backgroundColor.
#interface
- (void)setPersistentBackgroundColor:(UIColor*)color;
#implementation
- (void)setPersistentBackgroundColor:(UIColor*)color
{
super.backgroundColor = color;
}
- (void)setBackgroundColor:(UIColor *)color
{
// [super setBackgroundColor:color];
// prohibit from changing its background color.
}
