推荐答案
如果你需要在你的 uiviewcontroller 中加入导航控制器，你需要按照如下方式初始化它
If you need to incorporate a navigation controller in your uiviewcontroller you need to initialize it as it follows
UIViewController *yourViewController = ...
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:yourViewController];
[self presentModalViewController:navController animated:YES];
//you need to release the controller
[navController release];
如果你在 UIApplicationDelegate 方法中
If you are in the UIApplicationDelegate method
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
你不能做一个 presentModalViewController:navController 动画...然后你需要将 navController.view 添加到窗口
You can't do a presentModalViewController:navController animated... then you need to add the navController.view to the window
UIViewController *yourViewController = ...
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:yourViewController];
[self.window addSubview:navController.view];
//don't do a release of navController because is not retained by addSubview
