Cannot Set Cell Container BG Programmatically

Question

I have a UITableView cell setup like as BasicCell>ContentView>Container. When I set the container's background in interface builder, I get the desired darker shade of grey that I set it to. However, when I set that darker shade programmatically, in the cellForRowAtIndexPath, I get a white background.

cell.container.backgroundColor = UIColor(red: 20, green: 20, blue: 20, alpha: 1.0)

So by introducing a programmatic color setting, it suddenly ignores both the interface builder color and the programatic color. I've read several threads and tried things like using willDisplay cell:

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    let myCell = cell as! CustomTableViewCell_F2
    myCell.backgroundColor = UIColor.clearColor()
    myCell.backgroundView = nil
    myCell.container.backgroundColor = UIColor(red: 20, green: 20, blue: 20, alpha: 1.0)
}

I've tried setting it in the CustomTableCell class as well. That didn't work. What's happening and how do I solve it?

Try to change your tableView's background color. If this change will be visible through cells, remove myCell.backgroundColor = UIColor.clearColor() line. — Alexander Doloz
I changed the table BG color and it was visible. I then commented-out the myCell.background color line and still the container views are a white/very light shade of gray (hard to tell). — Dave G

Change

cell.container.backgroundColor = UIColor(red: 20, green: 20, blue: 20, alpha: 1.0)

to

let shade: CGFloat = 0.2
cell.container.backgroundColor = UIColor(white: shade, alpha: 1.0)

Your color UIColor(red: 20, green: 20, blue: 20, alpha: 1.0) is actually white. You should provide values for color components in range 0.0 to 1.0.
