Grouped Uitableview Remove Outer Separator Line

Grouped UITableview remove outer separator line

I just worked out a solution, as the cell has contentView which is a UIView, so I think you can just focus on the bottomline of contentView.

Here is my code:

first, you have to make the separator to clear

tableView.separatorColor = UIColor.clear

Second, in the cellForRowAt function:

let bottomBorder = CALayer()

bottomBorder.frame = CGRect(x: 0.0, y: 43.0, width: cell.contentView.frame.size.width, height: 1.0)
bottomBorder.backgroundColor = UIColor(white: 0.8, alpha: 1.0).cgColor
cell.contentView.layer.addSublayer(bottomBorder)

here you will see the UI like this:

How to remove UITableView section header separator

Don't know why you are returning UITableViewCell in viewForHeaderInSection method so may be it is possible that is showing separator of that UITableViewCell. Try returning the contentView of cell instead of cell from viewForHeaderInSection method.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let cell = tableView.dequeueReusableCell(withIdentifier: "headerTableViewCell")
    return cell.contentView
}

How to remove section header separator in iOS 15

Option 1:
Maybe by using UITableViewCellSeparatorStyleNone with the table view and replacing the system background view of the cell with a custom view which only features a bottom line?

Option 2: Using hint from https://developer.apple.com/forums/thread/684706

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 150000 // only Xcode 13+ needs and can compile this
    if (@available(iOS 15.0, *)) {
        [self.tableview setSectionHeaderTopPadding:0.0f];
    }
#endif
}

Remove single separator line from UITableViewCell

The easiest way is: don't use built-in separator lines. Draw the line yourself (as part of the cell) in each row where you want one, and don't draw it (i.e. remove it) in each row where you don't want it.

Remove first line separator of UItableView Cell

Within your cellForRowAt delegate function you can use:

    }
