UITableView with static cell - different separation color per section? - objective-c

Question

I have UITableView with static cells in 4 sections done in Storyboard. However, I want to change the separator color for one section ([UIColor clearColor]). How can I do that??? Is it actually possible?
I can set the separatorColor to clearColor for the entire table, but not only for one specific section.

Answer 1

AFAIK there is no method for this. But you can put a background image to the cell which has a separator at the bottom and set separatorstyle to UITableViewCellSeparatorStyleNone. So you have your own separator in every cell.

Answer 2

Maybe you can achieve your goal by setting the header text for the section to an empty string.

One approach would to create your own UIView subclass and do your own custom drawing in drawRect:. You would take this view and add it as the backgroundView of your table view cell. Something like this:
- (void)drawRect:(CGRect)rect
{
[super drawRect:rect];
// Drawing code
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(context, 1.0);
// Draw black line
CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB();
CGFloat components[] = {0.0, 0.0, 0.0, 0.3};
CGColorRef blackColor = CGColorCreate(colorspace, components);
CGContextSetStrokeColorWithColor(context, blackColor);
CGContextMoveToPoint(context, 0, rect.size.height - 1.5);
CGContextAddLineToPoint(context, rect.size.width, rect.size.height - 1.5);
CGContextStrokePath(context);
CGColorRelease(blackColor);
// Draw white bottom line
CGFloat whiteComponents[] = {1.0, 1.0, 1.0, 0.75f};
CGColorRef whiteColor = CGColorCreate(colorspace, whiteComponents);
CGContextSetStrokeColorWithColor(context, whiteColor);
CGContextMoveToPoint(context, 0, rect.size.height - 0.5);
CGContextAddLineToPoint(context, rect.size.width, rect.size.height - 0.5);
CGContextStrokePath(context);
CGColorRelease(whiteColor);
// Draw top white line
CGFloat whiteTransparentComponents[] = {1.0, 1.0, 1.0, 0.45};
CGColorRef whiteTransparentColor = CGColorCreate(colorspace, whiteTransparentComponents);
CGContextSetStrokeColorWithColor(context, whiteTransparentColor);
CGContextMoveToPoint(context, 0, 0.5);
CGContextAddLineToPoint(context, rect.size.width, 0.5);
CGContextStrokePath(context);
CGColorRelease(whiteTransparentColor);
CGColorSpaceRelease(colorspace);
}
