arraycontroller nsmutablearray add programmatically

Question

I trying to add a data on table view via Array Controller thats bind to a NSMutableArray. On the IB property it looks like this :

IB Property File's owner

and on the code I tried to add the NSMutableArray dynamically then reload the view, bu nothings happened.

for(int i=0;i<10;i++){
        NSMutableDictionary *group = [[NSMutableDictionary alloc]init];
        [group setValue:[NSString stringWithFormat:@"%@-%d", @"Group", i] forKey:@"groupname"];
        [contentArray addObject:group];
    }
    [tableContent reloadData];

I have been google it and browse the same question in stackoverflow, not found a useful one.

any idea ?

Thanks

I wrote above code in File's owner class.

What class is the code you posted in? And, did you log contentArray to make sure it has the objects in it that you expect? — rdelmar, Aug 14 '12 at 02:52
@rdelmar contentArray is refer to NSMutableArray, and tableContent is refer to NSTableView which an IBOutlet. — Alfian Busyro, Aug 14 '12 at 02:55
That's not the question I asked. What class is the code that you posted in? Is it in the app delegate? — rdelmar, Aug 14 '12 at 02:56
not an app delegate, but the class on file's owner, okay I will update my question — Alfian Busyro, Aug 14 '12 at 03:02

I think the problem is that the array needs to send a KVO notification to the array controller (or maybe it's the table view, I'm not sure). The way to do that is:

self.contentArray = contentArray; (or _contentArray if that's what your ivar is called). I'm assuming that contentArray is a property, if not, you should make it one.

thanks for your answer. hmm... actually I already put my contentArray as a property. – Alfian Busyro Aug 14 '12 at 04:44
@arufian yes, but did you add the line I put in my answer? – rdelmar Aug 14 '12 at 04:50
yes I put that one, nothings happened. btw, can I ask one simple question(it's not related though). Is it possible to build nstableview with view based for Snow Leopard ? – Alfian Busyro Aug 14 '12 at 04:56
I don't remember whether you can do that on Snow Leopard. Are you using a view based table? If so what are the columns bound to? It should be working, there must still be something wrong with the bindings. – rdelmar Aug 14 '12 at 05:09
yes I using view based table, I only have one column that contain Text Table Cell View (thats created on IB), then I bound the textfield to a key of contentArray. – Alfian Busyro Aug 14 '12 at 06:19

I don't think that's right. The table view's content binding should be bound to the array controller arrangedObjects. The textField should be bound to Table Cell View with a model key path of objectValue.groupName This is all described in the Table View Programming Guide in the "Creating the Bindings for a View-Based Table View" section – rdelmar Aug 14 '12 at 06:45
I see. But unfortunately, I have to implementing cell-based table view instead of view-based table view, because of the requirement. I'll accept this as the right answer. – Alfian Busyro Aug 14 '12 at 10:39
