View-Based NSTableView in Swift - How to - tableview

Question

I have a NSTableView whose cells are view-based.
DataSource & Delegate are connected, but I'm not able to display the cell's textField string value.
This is the code in Objective-C, working:
- (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView {
return 10;
}
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
NSTableCellView *cell = [tableView makeViewWithIdentifier:#"List" owner:self];
[cella.textField setStringValue:"Hey, this is a cell"];
return cell;
}
And here is my code in Swift, not working :
func numberOfRowsInTableView(aTableView: NSTableView!) -> Int
{
return 10 //Casual number
}
func tableView(tableView: NSTableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> NSTableCellView! {
var cell = tableView.makeViewWithIdentifier("List", owner: self) as NSTableCellView!
// setup cell without force unwrapping it
cell.textField.stringValue = "Hey, this is a cell"
println("Method called") //Never printed
return cell
}
This is the result: (table on right side of image)
Note that the comment //setup cell without force unwrapping it makes no sense, I forgot to delete it.
What I am missing ?
Edit: I tried even the following with no success:
func numberOfRowsInTableView(aTableView: NSTableView!) -> Int
{
return 10
}
func tableView(tableView: NSTableView!, objectValueForTableColumn tableColumn: NSTableColumn!, row: Int) -> AnyObject
{
var cell = tableView.makeViewWithIdentifier("List", owner: self) as NSTableCellView
cell.textField.stringValue = "Hey this is a cell"
return cell;
}
Thank you all.

Answer 1

After hours of search, I discovered this method that works !
func tableView(tableView: NSTableView, viewForTableColumn: NSTableColumn, row: Int) -> NSView
{
var cell = tableView.makeViewWithIdentifier("List", owner: self) as NSTableCellView
cell.textField.stringValue = "Hey, this is a cell"
return cell;
}

I see that you found your answer your self but from what I can see your clue was in the Return Value of Objective -C delegate.
- (NSView *)tableView:...
The return value is a NSView.
But you should look at the Swift/Objective -c documentaion.
From the Docs:
Providing Views for Rows and Columns
tableView:viewForTableColumn:row:
Asks the delegate for a view to display the specified row and column.
Declaration
SWIFT
#optional func tableView(_ tableView: NSTableView!,
viewForTableColumn tableColumn: NSTableColumn!,
row row: Int) -> NSView!
OBJECTIVE-C
- (NSView *)tableView:(NSTableView *)tableView
viewForTableColumn:(NSTableColumn *)tableColumn
row:(NSInteger)row
Note the -> NSView! in the swift code also.
The new docs allow you to see the code for Swift and Objective -c side by side or one or the other. You can use a selection tab at the top of the documentation to choose.
It also looks like your code should include the "!" for optionals

Answer 3

If you change the content mode of the table view from view based to cell based the method is called.

Answer 4

This beat me up for an hour. Works with Swift 2.2, probably won't work for earlier or later versions:
let cell = tableView.makeViewWithIdentifier(myid!, owner: nil) // You can't cast this with as! like they want you to
if let mycell = cell as? NSTableCellView {
mycell.textField?.stringValue = text
return mycell
}
