タブを隠す

tabbarを隠すには2つの方法があります.
1:pushViewControllerの前に呼び出す

[self setHidesBottomBarWhenPushed:YES];

現在のクラスでviewWillDisappearが呼び出されます.

- (void)viewWillDisappear:(BOOL)animated { 
    [self setHidesBottomBarWhenPushed:NO]; 
    [super viewDidDisappear:animated]; 
}

2:関数の使用:

- (void) hideTabBar:(BOOL) hidden{ 
    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:0]; 
    for(UIView *view in self.tabBarController.view.subviews) 
    { 
        if([view isKindOfClass:[UITabBar class]]) 
        { 
            if (hidden) { 
                [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)]; 
            } else { 
                [view setFrame:CGRectMake(view.frame.origin.x, 433, view.frame.size.width, view.frame.size.height)]; 
            } 
        } 
        else 
        { 
            if (hidden) { 
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)]; 
            } else { 
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 433)]; 
            } 
        } 
    } 
    [UIView commitAnimations]; 
}

方法1の方法コードは簡単で、インタフェースも少し制御します
