推荐答案
如果你需要在你的uiviewcontroller中加入一个导航控制器你需要初始化它
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
