Iphone 使用xcode 4在ios 5中创建选项卡式导航应用程序时出现问题

我正在尝试更改xcode 4上的一个选项卡式应用程序，以合并一个不带故事板的导航控制器。 第一个选项卡包含一个表。这是一个需要通航的

这是FirstViewController.h

#import <UIKit/UIKit.h>

@interface FirstViewController : UIViewController <UITableViewDelegate,     UITableViewDataSource> {
IBOutlet UITableView *storeDetailsTable;
}

@property (nonatomic, retain) UITableView *storeDetailsTable;
@property (nonatomic, strong) NSDictionary *resultData;
@property (nonatomic, strong) NSMutableArray *populatedStoreArray;
@property (nonatomic, strong) NSMutableArray *images;


@end

现在，当我构建并运行它时，我看到两个选项卡。但是第一个选项卡只是一个空白的黑屏，描绘了导航控制器，但是没有应该有的tableview

我错过了什么吗

谢谢..

在您的代码中，我看不到您正在初始化FirstViewController类并让NavController知道它。NavController需要使用RootViewController初始化，如：

NavController *myNavController = [[NavController alloc] initWithRootViewController:yourFirstViewController];

查找更多信息的好地方是：

#import <UIKit/UIKit.h>
@class NavController;

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate> {
    IBOutlet NavController *navController;
}

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

@end

#import "AppDelegate.h"
#import "FirstViewController.h"
#import "SecondViewController.h"
#import "NavController.h"

@implementation AppDelegate

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

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    navController = [[NavController alloc] initWithNibName:@"NavController" bundle:nil];
//        UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController, viewController2, nil];
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}

NavController *myNavController = [[NavController alloc] initWithRootViewController:yourFirstViewController];
