I am pasting this from my working code... you can call these methods to hide and show the tabbarcontroller.... just pass tabbarcontroller instance to these functions..
[self hideTabBar:self.tabBarController];
- (void) hideTabBar:(UITabBarController *) tabbarcontroller { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; for(UIView *view in tabbarcontroller.view.subviews) { if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)]; } } [UIView commitAnimations]; } - (void) showTabBar:(UITabBarController *) tabbarcontroller { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; for(UIView *view in tabbarcontroller.view.subviews) { NSLog(@"%@", view); if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)]; } } [UIView commitAnimations]; }
