NSTableView no selection highlight, but keep track of what row is selected - objective-c

Question

I've seen some threads with a similar question to this (not exactly the same) but the solutions there didn't solve my problem. I've create a NSTableView with a couple clickable elements in each TableCellView -- a TextField, a DatePicker and a Button -- and I need to be able to click into each of these without first selecting the row they are in. I achieved this by using setSelectionHighlightStyle: NSTableViewSelectionHighlightStyleNone However, I still need to know the index of the row that is being edited, because I need to pass the edits into a model object associated with each row. I tried writing the following, which was the suggestion of some of the other threads I mentioned, but it didn't do anything.
- (BOOL)tableView:(NSTableView *)tableView shouldTrackCell:(NSCell *)cell forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{
return YES;
}
I'm not 100% sure if that's the wrong method to use for this, or if I'm just implementing it incorrectly. Any tips on how I could go about this would be awesome.
Edit:
Here's my attempt at implementing Steve Waddicor's suggestions:
Making the ViewController the NSTableViewDataSource and set the TableCellView as the delegates for the objects (code is in MyViewController.m):
- (void)awakeFromNib{
[self.tableView setDataSource:self];
}
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
CustomTableCellView *view = [self.tableView makeViewWithIdentifier:#"MyIdentifier" owner:self];
[view.textField setDelegate:view];
[view.datePicker setDelegate:view];
return view;
}
//-----------------------
//-----------------------
//----------------------- NSTableViewDataSource Protocol Requirements:
- (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView
{
return [self.tableView numberOfRows];
}
- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex
{
return [self.tableView rowViewAtRow:rowIndex makeIfNecessary:NO];
}
and in CustomTableCellView, this is the delegate method which isn't being called when I click on the TextField, which leads me to believe that the delegates aren't being set for the objects correctly:
- (void)mouseDown:(NSEvent*) theEvent{
NSLog(#"TEST");
}

Answer 1

You could set the your tableCellView as the delegate of the controls. From there you could
NSTableView* tableView = self.superview;
NSUInteger row = [tableView rowForView:self];
Edit
To make a delegate. In your tableView dataSource you have a method something like this:
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
MyTableCellView* view = [outlineView makeViewWithIdentifier:#"MyIdentifier" owner:self];
[view.textField setDelegate:view];
[view.datePicker setDelegate:view];
[view.button setDelegate:view];
return view;
}

Answer 2

try this delegate
- (BOOL)tableView:(NSTableView *)aTableView shouldSelectRow:(NSInteger)rowIndex
{
return YES;
}
