如何在UISplitViewController for iPad中隐藏iPad

Question

我正在与UISplitViewController合作，在那里我需要隐藏第一DetailViewController的MasterViewController。这意味着，当应用程序启动时，MasterViewController必须是隐藏的，而不需要单击任何UIButton。我试着在UIViewControllers.But中使用UIViewControllers，什么都没发生。之后，我尝试在UISplitViewController中开发整个应用程序。下面是我试图隐藏MasterViewController的代码

masterViewController = [splitViewController.viewControllers objectAtIndex:0];
    detailVC = [splitViewController.viewControllers objectAtIndex:1];
    [master.view setFrame:CGRectMake(0, 0, 0, 0)];
    detail.view.frame = splitViewController.view.bounds; 

我花了一周时间做这件事，但是没有worked.Please提供solution.It会是很大的乐趣。

更新：

当我将委托设置为详细视图控制器时，它隐藏了所有视图控制器的主视图控制器。以下是我添加UISplitViewController的appDelegate代码。

self.splitViewController =[[UISplitViewController alloc]init];

    MasterTableViewController *masterViewController=[[MasterTableViewController alloc]initWithNibName:@"MasterTableViewController" bundle:nil];

    UINavigationController *masterNavigate=[[UINavigationController alloc]initWithRootViewController:masterViewController];

    DetailViewController *detailVC=[[DetailViewController alloc]initWithNibName:@"DetailViewController" bundle:nil];

    UINavigationController *detailNavigate=[[UINavigationController alloc]initWithRootViewController:detailVC];

    self.splitViewController.viewControllers=[NSArray arrayWithObjects:masterNavigate,detailNavigate, nil];

    self.splitViewController.delegate=detailVC;

    self.window.rootViewController=self.splitViewController;

在这里，我用Nex的代码将splitViewController的委托设置为detailVC.In detailViewController，我隐藏的是主视图控制器，当我从detailVC导航到其他视图时，它会隐藏主视图控制器。我知道这会让人恼火，但会有帮助的。

Answer 1

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

// this commant is used for showing or hiding the split view controller

svc.presentsWithGesture = TRUE; 

return YES;
}

// dont forget to assign the delegate like this in viewWillAppear


(self.splitViewController.delegate = self;)

Answer 2

您可以使用此委托方法隐藏主VC。

- (BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
    //Add your own logic to when you want the master VC hidden. 
    return YES;
}
