Answer 1

Try using this to hide tabbar

 - (void)hideTabBar:(UITabBarController *) tabbarcontroller
 {
       CGRect screenRect = [[UIScreen mainScreen] bounds];

       [UIView beginAnimations:nil context:NULL];
       [UIView setAnimationDuration:0.5];
       float fHeight = screenRect.size.height;
       if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) ){
           fHeight = screenRect.size.width;
       }

       for(UIView *view in tabbarcontroller.view.subviews){
            if([view isKindOfClass:[UITabBar class]]){
                 [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
            }else{
                 [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
                 view.backgroundColor = [UIColor blackColor];
            }
       }
       [UIView commitAnimations];
 }

and

 [self hideTabBar: UITabBarController1];

Answer 2

app.tabBarController.tabBar.hidden=TRUE;

app.tabBarController.tabBar.hidden=TRUE;

//Set some tab
[app.tabBarController setSelectedIndex:0];
