UIViewController加載UISplitViewController

我有一個UINavigationController作爲我的rootViewController，它包含一個UIViewController（我將爲此討論調用項目）。在Projects中，我有一個按鈕，點擊後，我想加載一個UISplitViewController - 最好從底部向上滑動，儘管這只是一個很好的功能。UIViewController加載UISplitViewController

在UISplitViewController，我有一個「關閉」按鈕，我想要刪除重新顯示項目的UISplitViewController。

從我讀到的，UISPlitViewControllers必須是rootViewControllers。考慮到這一點，我的代碼到目前爲止如下。

的AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 

    ... 

    // LOAD THE PROJECTS PANEL ROOT VIEW CONTROLLER INTO THE WINDOW 
    ProjectsListViewController *projects = [[ProjectsListViewController alloc] init]; 

    navigationController = [[UINavigationController alloc] initWithRootViewController:projects]; 

    [window setRootViewController:navigationController]; 
    [window makeKeyAndVisible]; 

    return YES; 
    }

ProjectsViewController

-(IBAction)loadDetails 
{  
    ProjectNavigationController *projectNavPanel = [[ProjectNavigationController alloc] init]; 
    ProjectDetailController *projectDetailPanel = [[ProjectDetailController alloc] init]; 
    ProjectSplitViewController *splitRootController = [[ProjectSplitViewController alloc] init]; 

    [splitRootController setViewControllers:[NSArray arrayWithObjects:projectNavPanel, projectDetailPanel, nil]]; 

    [[self view] removeFromSuperview]; 
    [[appDelegate window] setRootViewController:splitRootController]; 
}

UISplitViewController Naviagaion

- (void)loadProjects 
{ 
    // LOAD THE PROJECTS LIST BACK INTO VIEW 
    ProjectsListViewController *projectsList = [[ProjectsListViewController alloc] init]; 

    [[[self parentViewController] view] removeFromSuperview]; 
    [[appDelegate window] setRootViewController:projectsList]; 
}

現在，我知道這是錯誤的，不出所料，它對其他方法有不利影響。實際上，當我輸入這個時，我注意到Projects頁面在啓動時被加載到navigationController中，但是在splitViewController關閉時直接放置在窗口上。任何人都可以通過解釋實現這個的正確方法來幫助我嗎？

感謝
