Ios 带有NavigationBar的TabBar应用程序

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，我希望顶部有一个导航栏

然而，我需要将此应用程序中的所有内容本地化为几种语言，因此需要在代码中完成

我在AppDelegate中设置了选项卡栏

@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信息的代码

- (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;
}

到目前为止还不错，但是RecyclingView（TableView）需要一个导航栏，我可以在这里使用NSLocalizedString设置标题

我非常感谢您的帮助。

您可以使用Interface Builder对XIB进行本地化，这样您就不必通过编程实现

您需要在

选项卡控制器的
视图控制器的第二个索引处添加
UINavigationController
，而不是添加视图控制器-

- (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;
}

要在导航栏上设置标题，可以将其写入
RecycleViewController
的
viewDidLoad

[self.navigationItem setTitle:@"title"];

[self.navigationItem setTitle:@"title"];

xcode 4.3.2的答案是：

将RecycleViewController.m中的UINavigationBar分配为：

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

但是有一个错误，导航栏顶部会显示一个空白，大约10像素

这是另一个解决方案：
使用xib builder，在视图RecycleViewController.xib顶部的库中添加一个导航栏，按ctrl+“导航项”，指向RecycleViewController.h插入一个IBOutlet，然后将显示一个外观良好的导航栏。
