Question

I have an app where I have a TTTableView Controller inside a Navigation Controller that is Insider a TabBar.

I want it so that if a user selects an item it will push another TTTableView with the items under that category.

The code I have is

-(void)didSelectObject:(id)object atIndexPath:(NSIndexPath *)indexPath {
    if ([object isKindOfClass:[TTTableMoreButton class]]) {
        [super didSelectObject:object atIndexPath:indexPath];
    } else {
        CategoryViewController *viewController = [[CategoryViewController alloc] initWithNibName:@"CategoryViewController" bundle:nil];
        [self.navigationController pushViewController:viewController animated:YES];
        [viewController release];
    }
}

The CategoryViewController is setup as

@interface CategoryViewController : TTTableViewController

and the CategoryViewController.xib file has the datasource & delegate set to the files owner and the view set to the tableview and the tableview class is set to TTTableView.

When I run it I get the following error when selecting a row

2011-10-17 16:18:23.819 Biz Insider[34067:f803] -[CategoryViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x6c93d30

terminate called throwing an exceptionCurrent language:  auto; currently objective-c

If I try and push another view (i have one with a webview on it) then it works fine, or if I go into interface builder and link the File Owner’s “tableView” to the TTTableView object it will work fine and push the controller except the “Pull down to refresh” function wont work so I am assuming that the deletage isn’t correct when doing it that way.

Any help would be greatly appreciated.

EDIT:
I have a feeling that it has something to do with the following

-(id<UITableViewDelegate>)createDelegate {
    return [[[TTTableViewDragRefreshDelegate alloc] initWithController:self] autorelease];
}

This sets the delegate to TTTableViewDragRefreshDelegate which implements the numberOfRowsInSection and all that junk. Is there another way to do this?

Well this is an odd one, but I changed it from

CategoryViewController *viewController = [[CategoryViewController alloc] initWithNibName:@"CategoryViewController" bundle:nil];

to

CategoryViewController *viewController = [[CategoryViewController alloc] init];

and it magically works now…dont ask me how or why.

There must have been something in the NIB that was messing it up, but I dont know how the whole layout is working now with no NIB.
