Question

我正在构建一个基于TabBar的应用程序。其中一个选项卡将显示一个TableView，我希望在顶部有一个NavigationBar。

但是我需要将此应用中的所有内容本地化为多种语言，因此需要在代码中完成。

我在AppDelegate中设置了标签栏;

@implementation AppDelegate

@synthesize window = _window;
@synthesize tabBarController = _tabBarController;



- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    UIViewController *viewController1 = [[HomeViewController alloc] initWithNibName:@"HomeView" bundle:nil];
    UIViewController *viewController2 = [[RecycleViewController alloc] initWithNibName:@"RecycleView" bundle:nil];
    UIViewController *viewController3 = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil];
    UIViewController *viewController4 = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil];

    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2,viewController3, viewController4, nil];
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}

每个窗口都有选项卡上的信息代码。

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"Home", @"Home");
        self.tabBarItem.image = [UIImage imageNamed:@"home"];
    }
    return self;
}

到目前为止一切顺利，但RecyclingView（TableView）需要一个导航栏，我可以使用NSLocalizedString设置标题。

我真的很感激你的帮助。

您需要在UINavigationController的{{1}}的第二个索引处添加tabBarController，而不是添加视图控制器 -

viewControllers

要在导航栏设置标题，您可以在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. UIViewController *viewController1 = [[HomeViewController alloc] initWithNibName:@"HomeView" bundle:nil]; UIViewController *viewController2 = [[RecycleViewController alloc] initWithNibName:@"RecycleView" bundle:nil]; UIViewController *viewController3 = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; UIViewController *viewController4 = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController2]; self.tabBarController = [[UITabBarController alloc] init]; self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, navController,viewController3, viewController4, nil]; self.window.rootViewController = self.tabBarController; [self.window makeKeyAndVisible]; return YES; }的{{1}} {/ p>中写下这个标题

RecycleViewController

您可以使用Interface Builder本地化xib，因此您不必以编程方式执行此操作。

Answer 3

xcode 4.3.2的答案是：

在RecycleViewController.m中分配UINavigationBar：

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self];
self.view addSubview:navController.view;

但是有一个错误，导航栏会在顶部显示一个空白，大约10像素。

所以这是另一个解决方案：使用xib builder，在视图顶部的libary中添加一个导航栏RecycleViewController.xib，按ctrl +“导航项”，指向RecycleViewController.h插入一个IBOutlet，然后你会看到一个好看的导航栏。
