无论设备方向如何,都在SplitView中隐藏主视图控制器

Question

我发现很多人询问关于如何有主视图中显示无论是在横向和纵向的,但我试图做的是不管有隐藏的设备方向的右主视图,然后从弹出中通过使用导航栏按钮.

如果有人能告诉我在设备重新定位时隐藏主视图的逻辑位于/执行的地方,那将对我有多大帮助.我一直在寻找的是配有适用于iOS的Xcode,主/详细信息视图模板,我注意到这两个以下方法在AppDelegate.m文件中声明,但我似乎无法找出他们正在从执行:

//Called when a button should be added to the nav bar for a view that is hidden
- (void)splitViewController:(UISplitViewController *)splitController willHideViewController: (UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
{
   barButtonItem.title = NSLocalizedString(@"Master", @"Master");
   [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES];
   self.masterPopoverController = popoverController;
}

- (void)splitViewController:(UISplitViewController *)splitController willShowViewController:(UIViewController *)viewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem
{
    // Called when the view is shown again in the split view, invalidating the button and popover controller.
    [self.navigationItem setLeftBarButtonItem:nil animated:YES];
    self.masterPopoverController = nil;
}

所有帮助将不胜感激.

实际上你无法控制UISplitViewController.主视图始终存在于横向视图中,并且无法更改此视图.

但是,"Matt Gemmell创建了一个名为'MGSplitViewController'的优秀自定义splitViewController.它非常容易实现,评论很多,并且包含许多普通splitViewController所没有的优秀功能(隐藏景观视图上的主视图,更改分割的位置)在横向视图中,允许用户在运行期间流畅地更改分割的大小等.)"

我之前在类似(但不同)的问题中发布了这个问题,并在此处给出了相同的答案:

如何在ipad中隐藏UiSplitviewcontroller中的主视图

- = - = - = - = - = - = - = - = - = - = - = -

更新:

在iOS 5.0及更高版本中,他们最终添加了隐藏主视图的功能!

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