How does editing work in view based NSTableView?

Question

Cocoa

Can anyone help explain how editing works in a view based NSTableView? I'm trying to implement a behavior where double-clicking replaces the view and shows more detailed editing of the cell's data.
I rummaged through the entire StackOverflow, read the mountain of Apple documentation, call editing on a double click ... I even learned how to replace the view, but I can’t edit the rest of the fields in the cell, editing closes immediately. As I understand it, there you need to figure out the mechanism for transferring focus from a cell to a textField through firstResponder.
Just in case: in the application I use Core Data and Cocoa Bindings.
If there is someone who really cuts in this topic, then I’m even ready to pay him money for a consultation, since this is not the last difficult issue for me that I want to thoroughly understand.

Answer 1

OS X, yes.
When double-clicking, the @property editingRow value changes, the table is reloaded, the view is replaced, and editing begins. You have to use both delegation and cocoa bindings at the same time. I haven't found a better way yet.
The current solution works, but only if you have one textField per cell. The rest cannot be edited, with any click, the editing mode is turned off.
I need not to edit the current solution, but to understand how this should be done in principle. I found two paragraphs on this topic
in the Apple docks :

- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
        // getting tableview's arraycontroller
        NSArrayController *arrayController = [[tableView infoForBinding:NSContentBinding] valueForKey:NSObservedObjectKey];
        
        // checking if task was done and assigning custom cellview
        NSNumber *done = [arrayController.arrangedObjects[row] valueForKey:@"done"];
        if ([done boolValue]) {
                return [tableView makeViewWithIdentifier:@"done" owner:self];
        } else if (self.editingRow == row) {
                return [tableView makeViewWithIdentifier:@"editing" owner:self];
        } else {
                return [tableView makeViewWithIdentifier:@"regular" owner:self];
        }
}

- (void)doubleClick:(id)sender
{
        NSInteger clickedRow = [sender clickedRow];
        if (clickedRow != -1) {
                self.editingRow = clickedRow;
                [self.somedayTableView reloadData];
                [sender editColumn:0 row:[sender clickedRow] withEvent:nil select:YES];
        }
}

here the implementation would probably help if the answer was written for half a year. may help someone else. macbug.ru/macosxsample/canimnstableview
