Setting NSTableView cell text

Question

I have a NSTableView that I want to populate with 20 cells, each of them will say "Test". I'm fluent with UITableView's but not so much with NSTableViews, so I went hunting online to figure this out. Oh, how confused that made me! I understand that I need to use the numberOfRowsInTableView function, but how do I set the text of the cell? Each source I find seems to do everything in a different way. For instance, this site uses:

func tableView(tableView: NSTableView!, viewForTableColumn tableColumn: NSTableColumn!, row: Int) -> NSView! {
// 1
var cellView: NSTableCellView = tableView.makeViewWithIdentifier(tableColumn.identifier, owner: self) as NSTableCellView

// 2
if tableColumn.identifier == "BugColumn" {
  // 3
  let bugDoc = self.bugs[row]
  cellView.imageView!.image = bugDoc.thumbImage
  cellView.textField!.stringValue = bugDoc.data.title
  return cellView
}

return cellView

}

I tried that but I got an error - the code found nil while unwrapping an optional. Then I tried what I found here :

func tableView(tableView: NSTableView, dataCellForTableColumn tableColumn: NSTableColumn?, row: Int) -> NSCell? {
if tableColumn == nil { return nil }
if tableColumn!.identifier != "right" { return nil }
let cell = NSPopUpButtonCell()
cell.bordered = false
cell.menu!.addItemWithTitle("one", action: nil, keyEquivalent: "")
cell.menu!.addItemWithTitle("two", action: nil, keyEquivalent: "")
cell.menu!.addItemWithTitle("three", action: nil, keyEquivalent: "")
cell.selectItemAtIndex(1) // <--- obviously ignored ?!
return cell

}

So my question is, how do I set the cell text? How do the two examples I've inserted above differ in what they do? Please, make some sense of this - cause I sure can't!

-Thanks, A confused CodeIt

PS I've looked at several other sources except the two I named above. I'm just plain confused..

Edit: The found nil while unwrapping an Optional error I mentioned in the first example is found on this line:

var cellView: NSTableCellView = tableView.makeViewWithIdentifier(tableColumn.identifier, owner: self) as NSTableCellView

Answer 1

// Get an existing cell with the MyView identifier if it exists

var cellView?: NSTableCellView = tableView.makeViewWithIdentifier("someIdentifier", owner: self) as NSTableCellView

// There is no existing cell to reuse so create a new one

if cellView == nil {
    cellView = NSTableCellView(frame: NSRect())
// The identifier of the NSTextField instance is set to someIdentifier.
// This allows the cell to be reused.
     cellView.identifier = "someIdentifier
}

This should give you the cell, and you can proceed. See Apple Doc for more
