我正在为这个问题而抓狂，并且已经持续了几个星期。XCode 4.2 与针对 IOS4 的构建，所以我正在处理 .XIB 文件。

我正在编写一个 iphone 应用程序，其中包含通过 tabBar 提供的两个选项卡，1）我的艺术家，2）所有艺术家。每个选项卡都有一个精美的 UITableview。还有一个详细视图，可显示有关该作品的更多信息。（还有一个 HUD 显示，它是 Matej Bukovinski 的 MBProgressHUD 的副本）

当我调用 didSelectRowAtIndexPath 时，我无法调出详细视图来挽救我的生命。（它确实可以正确触发。

我知道我必须缺少一些基本的东西，但是……我就是找不到它来挽救我的生命。

提前致谢。

在 AppDelegate.m 中，您必须将 UINavigationController 添加到标签栏视图控制器而不是普通视图控制器：

- (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;
}
