组合导航控制器与制表条控制器 [英] Combining Navigation Controller with Tab Bar Controller

问题描述

正如我在标题中提到的，我想向我的应用程序添加 Navigation Controller ，该应用程序已经有一个 Tab控制器。所以试图做这个工作人员像这个页面。无论如何，有什么不对。 UINavigationController 正在寻找一个空白页，即使有一个视图和一些库。

As I mentioned in the title, I want to add Navigation Controller to my application which already has a Tab Controller. So trying to do the staff something like on this page. Anyway, something is wrong. UINavigationController is looking a blank page, even if has a view and some libraries.

让我从stracht开始：

Let me begin from the stracht:

在我的 AppDelegate 中，我设置的标签栏控制器如下：

In my AppDelegate, I'm setting tab bar controllers like this:

@interface MYAppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UITabBarController *tabBarController;

@end

这里是.m文件：

@implementation MYAppDelegate

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

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.applicationSupportsShakeToEdit = YES;
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    UINavigationController *viewController1 = [[[MYMainViewController alloc] init] initWithNibName: @"MYMainViewController" bundle:nil];
    UIViewController *viewController2 = [[[MYPageViewController alloc] init] initWithNibName:@"MYPageViewController" bundle:nil];
    UIViewController *viewController3 = [[[MYSearchViewController alloc] init] initWithNibName:@"MYSearchViewController" bundle:nil];
    UIViewController *viewController4 = [[[MYPersonViewController alloc] init] initWithNibName:@"MYPersonViewController" bundle:nil];

    // Initialize tabBarController and add ViewControllers
    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;
}

然后，这里是 MYMainViewController implementationaion这是一个 UINavigationController ：

Then, here is MYMainViewController implementaion which is a UINavigationController:

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"%@", [self navigationController]); // Logging null
}

我的.xib文件有一个 UINavigationController 并且有一个视图。虽然，当我工作的应用程序，有空白页和未命名的导航栏。

My .xib file has a UINavigationController and and there is a view in it. Althought it, when I worked the app, there is blank page and untitled navigation bar. What am I doing wrong?

如果我可以看到我的视图的内容，我想使用后退按钮在两个视图控制器之间切换。

If I could see the content of my view, I want to navigate between two view controllers by using back button.

任何帮助或方法对我都很好。

Any help or approach would be great for me.

推荐答案

尝试删除导航控制器xib，所以它只有视图控制器，然后初始化导航控制器编程：

Try to remove navigation controller from xib, so it only have view controller, then initialize navigation controller programatically:

UIViewController *tmpViewController1 = [[[YourViewController alloc] init] initWithNibName:@"YourViewController" bundle:nil];
 UINavigationController *viewController1 =  [[UINavigationController alloc] initWithRootViewController:tmpViewController1];
