UITableView didSelectRowAtIndex TabBar和子視圖不起作用

Question

我在這個陷阱上扯了頭發，已經呆了幾個星期了。 XCode 4.2的構建針對IOS4，因此我正在處理.XIB文件。

我正在編寫一個iPhone應用程序，其中包含兩個通過tabBar提供的選項卡，1）我的藝術家，2）所有藝術家。 每個選項卡都有一個精美的UITableview。 還有一個詳細視圖，顯示有關該作品的更多信息。 （還有一個HUD顯示，它是Matej Bukovinski的MBProgressHUD的副本）

當我調用didSelectRowAtIndexPath時，我無法調出細節視圖來挽救生命。 （它確實可以正確觸發。

我知道我必須缺少一些基本知識，但是...我只是找不到它來挽救生命。

提前致謝。

在AppDelegate.m中，必須將UINavigationController添加到選項卡視圖控件而不是普通的View controller：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    //Test on navigationController
    //navigationController = [[UINavigationController alloc] initWithRootViewController:MyArtistsViewController];
    // Override point for customization after application launch.
    UIViewController *artistsVC = [[[MyArtistsViewController alloc] initWithNibName:@"MyArtistsViewController" bundle:nil] autorelease]; //remove autorelease if ARC support
    UINavigationController *viewController1 = [[[UINavigationController alloc] initWithRootViewController:artistsVC] autorelease];

    //UIViewController *tvc = [[TicketViewController alloc] initWithNibName:@"TicketViewController" bundle:nil]; 
    //self.navigationController = [[UINavigationController alloc] initWithRootViewController:_tabBarController];


    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];


    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}
