Ipad 如何在UISplitView中隐藏主视图

我试图在横向模式下在UISplitView中隐藏主视图。这是我想做的一个按钮点击。在我的导航栏中，我点击了一个按钮，我想在横向模式下隐藏主视图。此外，如果主视图是隐藏的，则单击同一按钮时，主视图应显示回来。所有这些都需要在主视图中完成。我提到了以下函数

-(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
return YES;
}

但它在视图加载时隐藏主视图，尽管单击了按钮。下面是我的详细视图代码

- (void)setDetailItem:(id)newDetailItem {
if (detailItem != newDetailItem) {
[detailItem release];
detailItem = [newDetailItem retain];

        // Update the view.
        NSLog(@"Detail item in detail view::%@",detailItem);
        NSString *imageName = [NSString stringWithFormat:@"%@.jpg",[detailItem description]];
        NSLog(@"Image name is::%@",imageName);
        self.imageToDisplay.image = [UIImage imageNamed:imageName];
        [self configureView];
    }

    if (mainpopover != nil) {
        [mainpopover dismissPopoverAnimated:YES];
    }        
}

- (void)configureView 
{
    // Update the user interface for the detail item.  
    detailDescriptionLabel.text = [detailItem description];

    openInButton = [[UIBarButtonItem alloc] initWithTitle:@"OpenIn" style:UIBarButtonItemStyleDone target:self action:@selector(openIn)];
    favoritesButton = [[UIBarButtonItem alloc] initWithTitle:@"*" style:UIBarButtonItemStyleDone target:self action:@selector(markFavorite)];
    emailButton = [[UIBarButtonItem alloc] initWithTitle:@"E" style:UIBarButtonItemStyleDone target:self action:@selector(emailFile)];
    uploadButton = [[UIBarButtonItem alloc] initWithTitle:@"#" style:UIBarButtonItemStyleDone target:self action:@selector(uploadFile)];

    self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:openInButton, favoritesButton,emailButton, uploadButton, nil];
}
