I have an NSArrayController containing items and a text field in a window
which is bound to a custom class "MyController" via model key path:
filteredResultsString
-(NSString *)filteredResultsString
{
return ([[NSNumber numberWithInt:[[itemsController arrangedObjects] count]]
stringValue]);
}
This works, except when the contents of the NSArrayController change it does
not update.
If I change the binding to controller key arrngedObjects model key path
@count it works perfectly, but I want to use my custom method to customize
the output in a way that a Display Pattern can't.
How do I get this to work?
