问题描述
有人能指出我如何在 UITabBarController 中设置 UINavigationController 的正确方向吗?我有一种感觉,我使用 initWithRootViewController 是错误的.
Can someone point me in the right direction with how to set up a UINavigationController inside of a UITabBarController? I have a feeling I'm using initWithRootViewController wrong.
ViewController1 *viewController1 = [[[ViewController1 alloc] initWithNibName:@"ViewController1" bundle:nil] autorelease];
self.navController = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease];
ViewController2 *viewController2 = [[[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil] autorelease];
ViewController3 *viewController3 = [[[ViewController3 alloc] initWithNibName:@"ViewController3" bundle:nil] autorelease];
ViewController4 *viewController4 = [[[ViewController4 alloc] initWithNibName:@"ViewController4" bundle:nil] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
_tabBarController.viewControllers = [NSArray arrayWithObjects:navController, viewController2, viewController3, viewController4, nil];
self.tabBarController.delegate = self;
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
感谢大家的建议.
推荐答案
在 AppDelegate 中,你把这个:
In the AppDelegate, you put this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
UIViewController *viewController1 = [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];
UINavigationController *navC1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];
UINavigationController *navC2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
UIViewController *viewController3 = [[[FirstViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil] autorelease];
UINavigationController *navC3 = [[UINavigationController alloc] initWithRootViewController:viewController3];
UIViewController *viewController4 = [[[SecondViewController alloc] initWithNibName:@"ForthViewController" bundle:nil] autorelease];
UINavigationController *navC4 = [[UINavigationController alloc] initWithRootViewController:viewController4];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navC1, navC2, navC4, navC4, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
