i had programetically add the tabbar as shown below:-
FirstViewController *obj_FirstViewController = [[FirstViewController alloc] initWithNibName:@\"FirstVie
Try this way...
NSMutableArray *controllers = [[NSMutableArray alloc] init];
FirstViewController *obj_FirstViewController = [[FirstViewController alloc] init];
[obj_FirstViewController setTitle:@"first"];
UITabBarItem *item = [[[UITabBarItem alloc] setTabBarItem: [[[UITabBarItem alloc] initWithTitle: @"First") image:[UIImage imageNamed:@"first.png"] tag:2] autorelease]];
[obj_FirstViewController setTabBarItem:item];
[controllers addObject:obj_FirstViewController];
[obj_FirstViewController release];
