Problems loading text to xib using plist in tableview's selected cell

Question

I am developing an app that starts with a grouped tableview cell.  Each cell has an image, text, and description from a plist.  When a cell is chosen a xib is loaded by a view controller in the plist.  I want to load into the xib some text, an image, and a sound file that is in the plist (dict for that cell).  This way I don't have to have lots of view controllers and xibs.  I have been able to load the xib using this method but I can't get the images and text to load.  I have been able to do it when I don't have a grouped table view but when I add the grouping in the plist the connection is lost.  below is my code.  Could someone look at it and tell me where I've gone wrong, how to correct it, or another way to do what I want to do?
I know I am not calling the right array and then dictionary but I don't know how to correct this.  Help please.

I think you problem lies in this part.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath {
    const NSDictionary *const row = [self rowForIndexPath:indexPath];
    NSString *wantedClassName = [row objectForKey:@"controller"];
    UIViewController *const vc = [[NSClassFromString (wantedClassName) alloc] init];
    NSLog(@"controller is -%@-", wantedClassName);
    [self.navigationController pushViewController:vc animated:YES];
    TableViewPushAppDelegate *appDelegate = ( TableViewPushAppDelegate *)[[UIApplication sharedApplication]delegate];
    appDelegate.myImage = [[NSString alloc]initWithFormat:@"%@",[[tableDataSmobjectAtIndex:indexPath.row]objectForKey:@"picture"]];
NSLog(@"%@", appDelegate.myImage);
appDelegate.textView = [[NSString alloc]initWithFormat:@"%@",[[tableDataSm objectAtIndex:indexPath.row]objectForKey:@"description"]];
    [vc release];
specifically the underlined part.  does this need modifying or completely rewritten.
