Binding view-based NSOutlineView to Core Data

Question

I\'m trying to implement the new view-based OutlineView as a source list in my Mac app. I can\'t get values to display, though, so I made a small test app from the Core Data app

Answer 1

I have created a little sample project which popuplates also popuplates an NSOutlineView, not with CoreData but the crucial factor is, like @boaz-stuller stated that the correct cell is selected (similar to how you handle UITableViewCells in iOS.

So in my case I have implemented the method like so:

- (NSView *)outlineView:(NSOutlineView *)outlineView viewForTableColumn:(NSTableColumn *)tableColumn item:(id)item {

    if ([self isHeader:item]) {
        return [outlineView makeViewWithIdentifier:@"HeaderCell" owner:self];
    } else {
        return [outlineView makeViewWithIdentifier:@"DataCell" owner:self];
    }
}
