使用SWIFT在Tableview中设置自定义单元格

Question

I'm trying to create a custom cell that will only be applied to one single CELL in a Section.

So a create a custom cass called buttonsTableViewCell, that is pretty much empty and only have one label called weightLabel() code bellow:

class buttonsTableViewCell: UITableViewCell {

    @IBOutlet weak var weightLabel: UILabel!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

}

On the Main.storyboard i connected everything:

Now this is what i'm trying to do in the viewcontroller class, that controls the Tableview that has the cell.

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

 var cell = tableView.dequeueReusableCellWithIdentifier("Cell",   forIndexPath: indexPath) as UITableViewCell
          cell.textLabel?.text = "Testing"

if indexPath.row == 1 { // So it only changes this cell
  cell = tableView.dequeueReusableCellWithIdentifier("buttonsCell", forIndexPath: indexPath) as buttonsTableViewCell

  cell.weightLabel?.text = "Weight" // ERROR UITableViewCell does not have a member named 'weightLabel'
}

 return cell

}

What i'm doing wrong? Thanks in advance for the help.

Swift is statically typed language with type inference. So when you first assign the value of cell outside your if condition, the type of the cell variable is set to a normal UITableViewCell .
Just use a different variable name like

if indexPath.row == 1 { 
    var buttonCell = tableView.dequeueReusableCellWithIdentifier("buttonsCell", forIndexPath: indexPath) as buttonsTableViewCell

    buttonCell.weightLabel?.text = "Weight" 
    return buttonCell
}

var cell = tableView.dequeueReusableCellWithIdentifier("Cell",   forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = "Testing"

return cell
