Answer 1

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;

}

Answer 2

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.
