问题与自定义导航控制器的iOS 6

Question

我在的appDelegate创建自定义导航控制器：

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]; 

所以这个问题是我需要的viewController我的应用程序的午餐，但如果我把我的viewController为RootViewController的，我的导航控制器不会推导航，反之亦然，如果将我的导航控制器设置为根，则不会从菜单或主视图控制器加载应用程序。

为什么你创建Poemsview作为导航控制器的rootviewcontroller？

如果您想首先加载ViewController然后使用下面的代码。

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]; 

您可以创建另一个导航控制器作为Sub-class of Viewcontroller.

在你的诗按钮操作添加以下内容：

// 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]; 

现在你可以能够推详细视图从您tableview DidselectRowAtindexpath。
