如何在MasterView上隐藏UISplitViewController iOS7.1

Question

我正在iOS上开发一个应用程序，它显示一个UISplitViewController。在纵向模式中，显示/隐藏主视图控制器(MenuPrincipalVC)的按钮如下：

​

​

然而，当我旋转视图控制器时，无论菜单是否隐藏在纵向视图中，它总是可见的

​

​

我希望主视图在两个方向(景观和纵向)上具有相同的行为，我希望主视图(MenuPrincipalVC)被隐藏，并在顶部设置一个按钮来显示/hidding主视图控制器，这是我的代码：

这是为了创建SplitView并显示它，masterViewController总是MenuPrincipalVC，但是detailView依赖于rightViewController：

#pragma mark *** UISplitViewController methods ***
-(void)showSplitViewControllerInView:(UIView *)view
            withDetailViewController:(id)rightViewController{

    UIStoryboard *mainStoryboard        = [UIStoryboard storyboardWithName:@"iPad" bundle: nil];

    UINavigationController  *leftNavController;
    UINavigationController  *rightNavController;

    MenuPrincipalVC  *leftViewController     = [mainStoryboard instantiateViewControllerWithIdentifier:@"MenuPrincipalVC"];
    leftViewController.title            = @" ";


    leftNavController                   = [[UINavigationController alloc] initWithRootViewController:leftViewController];
    rightNavController                  = [[UINavigationController alloc] initWithRootViewController:rightViewController];

    leftNavController.toolbarHidden                 = FALSE;
    rightNavController.toolbarHidden                = FALSE;
    leftNavController.navigationBar.translucent     = TRUE;
    rightNavController.navigationBar.translucent    = TRUE;
    leftNavController.toolbar.translucent           = FALSE;
    rightNavController.toolbar.translucent          = TRUE;

    UISplitViewController   *splitViewController    = [[UISplitViewController alloc] init];
    splitViewController.viewControllers             = [NSArray arrayWithObjects:leftNavController, rightNavController, nil];
    splitViewController.delegate                    = rightViewController;

    if ([splitViewController respondsToSelector:@selector(setPresentsWithGesture:)]) {
        [splitViewController setPresentsWithGesture:NO];
    }

    view.window.rootViewController      = splitViewController;
}
#pragma -

在我的rightViewController上，我设置了以下方法：

#pragma mark - UISplitViewDelegate methods
-(void)splitViewController:(UISplitViewController *)svc
    willHideViewController:(UIViewController *)aViewController
         withBarButtonItem:(UIBarButtonItem *)barButtonItem
      forPopoverController:(UIPopoverController *)pc{

    //Grab a reference to the popover
    self.popover                    = pc;

    barButtonItem.title             = [NSString fontAwesomeIconStringForEnum:FABars];
    NSDictionary *textAttributes    = @{NSFontAttributeName : [UIFont fontWithName:kFontAwesomeFamilyName
                                                                              size:TOOLBAR_ICONS_SIZE],
                                        NSForegroundColorAttributeName : [UIColor whiteColor]};
    [barButtonItem setTitleTextAttributes:textAttributes forState:UIControlStateNormal];


    UINavigationItem *navItem       = self.navigationItem;
    [navItem setLeftBarButtonItem:barButtonItem animated:YES];
}

-(void)splitViewController:(UISplitViewController *)svc
    willShowViewController:(UIViewController *)aViewController
 invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem{


    //Remove the barButtonItem.
    [_navBarItem setLeftBarButtonItem:nil animated:YES];

    //Nil out the pointer to the popover.
    _popover = nil;

}
#pragma mark -

谢谢你的支持

Answer 1

我所要做的就是将下一行代码添加到详细的视图控制器中：

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

Answer 2

另一种解决方案可能只是专门设置主视图控制器的宽度(当然，表示控制器总是可以替代行为古怪和难以使用的分割视图方法)。
