Excellent response. In the future, it is always better if you include
code or a description of your attempts (even if it's just looking at
the documentation).
- (IBAction)remove:(id)sender {
NSArray *selectedRow = [treeController selectedObjects];
As you noticed, this returns an array, not a single object.
NSInteger childrenCount = [selectedRow.children count];
Which makes this line suspect. An array doesn't have children. Didn't
the compiler issue an error/warning here? If not, you'll probably want
to turn on all warnings and treat warnings as errors. Those options
are so frequently used I think they should be the standard behavior.
