Answer 1

我从我的工作代码中粘贴这个...你可以调用这些方法来隐藏和显示tabbarcontroller ....只需将tabbarcontroller实例传递给这些函数..

// Method call[self hideTabBar:self.tabBarController];

---

// Method implementations- (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]; }

改进的Setomidor对横向，纵向和iPad工作的回答（320和480值仅适用于iPhone）。

- (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];}- (void) showTabBar:(UITabBarController *) tabbarcontroller 
{   
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    float fHeight = screenRect.size.height - tabbarcontroller.tabBar.frame.size.height;

    if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
    {
        fHeight = screenRect.size.width - tabbarcontroller.tabBar.frame.size.height;
    }

    [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, 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)];
        }       
    }
    [UIView commitAnimations]; }

还修改了代码以处理iOS 6中引入的更改，并更改了UIDevice方向，并确保即使设备背面也能正常工作。

在按钮的操作方法中：

[self.tabBarController.tabBar setHidden:YES];
