Question

我在appDelegate中创建了一个自定义导航控制器：

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

poemsView  = [[[PoemsViewController alloc]initWithNibName:@"PoemsViewController" bundle:nil] autorelease];
self.navigationController = [[[UINavigationController alloc] initWithRootViewController:poemsView] autorelease];
self.navigationController.navigationBarHidden = YES;


self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.navigationController;

[self.window makeKeyAndVisible];

所以问题是我需要来自viewController的app午餐，但是如果我将viewController设置为rootviewController，我的导航控制器不会推送导航，反之亦然，如果将我的导航控制器设置为root，app不会从菜单加载或主视图控制器。

为什么要将Poemsview创建为导航控制器的rootviewcontroller？

如果您想首先加载ViewController，请使用以下代码。

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];

poemsView  = [[[PoemsViewController alloc]initWithNibName:@"PoemsViewController" bundle:nil] autorelease];

self.navigationController = [[[UINavigationController alloc] initWithRootViewController:self.viewController] autorelease];

self.navigationController.navigationBarHidden = YES;



self.window.rootViewController = self.navigationController;

[self.window makeKeyAndVisible];

您可以将另一个导航控制器创建为Sub-class of Viewcontroller.

在你的诗歌按钮动作中添加以下内容：

// Create a regular view controller.
PoemViewController *modalViewController = [[[PoemViewController alloc] initWithNibName:@"PoemViewController" bundle:nil] autorelease];

// Create a navigation controller containing the view controller.
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController];

// Present the navigation controller as a modal view controller on top of an existing navigation controller
[self presentModalViewController:secondNavigationController animated:YES];

现在，您可以从tableview DidselectRowAtindexpath。
