semanticContentAttribute is not working anymore with default UITableViewCells

Question

I have a running app, and I'm trying to add RTL language support.

I use the line below in my AppDelegate to execute after start, specifically in didFinishLaunchingWithOptions.

UIView.appearance().semanticContentAttribute = .forceRightToLeft

It was working perfectly on iOS 10, but now on iOS 11, the default tableView cell's labels are still aligned LTR.

Answer 1

You should set the label's semantic content attribute to .forceRightToLeft as well.

Programmatically

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: <your cell ID>, for: indexPath)
    cell.textLabel?.semanticContentAttribute = .forceRightToLeft

    return cell
}

In Interface Builder

1. Select the text label of the cell.

   

2. Open the Attributes inspector (the fourth icon from the left) from the toolbar on the right.

   

3. In the View section, set the Semantic option to Force Right-to-Left.
