Using UITableViewDataSource with Custom Cells Having Subviews

Question

When using a custom cell in a UITableView I am getting a strange table overlap:

Problem

• scroll down & last two rows have top two r

Answer 1

The problem with cell identifier must be unique

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let  cellId:String = "Cell"+String(indexPath.row)
    var cell  = tableView.dequeueReusableCellWithIdentifier(cellId)
    if (cell == nil){
        cell = UITableViewCell(style: .Default, reuseIdentifier:cellId)
    }
    let cellText:String = String(indexPath.row)
    let subjectField:UILabel = UILabel(frame: CGRect(x:55, y: 25, width: 303, height:  25))

    subjectField.text = cellText

    (cell! as UITableViewCell).addSubview(subjectField)

    return cell! as UITableViewCell

}
