UITableViewCell - selected background size based on content - ios

Question

I have this code to get table cell
func getCell(_ tableView: UITableView) -> UITableViewCell? {
var cell:UITableViewCell? = tableView.dequeueReusableCell(withIdentifier: CELL_REUSE_ID)
if (cell == nil)
{
//init and configure the cell
cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: CELL_REUSE_ID)
let selectedView:UIView = UIView(frame: CGRect(x: 0, y: 0, width: cell!.frame.size.width, height: cell!.frame.size.height))
selectedView.backgroundColor = UIColor.black.withAlphaComponent(0.3)
let layer = selectedView.layer
layer.borderColor = UIColor.blue.cgColor
layer.borderWidth = getCellBorderWidth();
layer.cornerRadius = getCellCornerRadius();
layer.backgroundColor = UIColor.blue.cgColor
cell!.selectedBackgroundView = selectedView
}
return cell
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell:UITableViewCell? = getCell(tableView)
cell!.backgroundColor = UIColor.clear
cell!.textLabel!.textColor = UIColor.darkText
cell!.textLabel!.text = tableData[indexPath.row]
cell!.textLabel!.textAlignment = .right
cell!.textLabel!.numberOfLines = 1
cell!.textLabel!.adjustsFontSizeToFitWidth = true
return cell!
}
Cells and table are generated in code, no xibs. Now, If I select cell, the background is covering entire width of table. How can I do background for some cells, that is only half of the table width (or some other percentual ratio)?

Answer 1

I think U can add another view to selectedBackgroundView
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCell(withIdentifier: "cell")
if cell == nil {
cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
// selectedBackgroundView
let backgroundView = UIView()
backgroundView.backgroundColor = UIColor(white: 0, alpha: 0)
// add another view to selectedBackgroundView, and set any frame for this view
let selectView = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 40))
selectView.backgroundColor = .red
backgroundView.addSubview(selectView)
cell?.selectedBackgroundView = backgroundView
}
return cell!
}
