it is toolbar not tabbar.
in .h file

IBoulet UINavigationController *navigationController;

IBoulet UIToolBar *toolbar;

connect IBoulet in in XIB

in .m file

- (void)viewDidLoad {

    [super viewDidLoad];

    [navigationController setNavigationBarHidden:YES];

    toolbar.hidden = TRUE;

}


- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
   UITouch *touch = [touches anyObject];

    if (touch.tapCount == 2) {

             [navigationController setNavigationBarHidden:NO];
             toolbar.hidden = FALSE;

             [NSTimer scheduledTimerWithTimeInterval:(1.0) target:self   selector:@selector(hideBar) userInfo:nil repeats:NO];

    }

 }

 - (void)hidebar 
  {    
    [navigationController setNavigationBarHidden:YES];

    toolbar.hidden = TRUE;
}

If you're using priyanka's code, the toolbar.hidden = TRUE (all caps!) and fix that everywhere else as well.

The accepted values for a BOOL are YES, NO, TRUE, FALSE, 0, and 1.
