基于 UINavigationController 的应用程序，带有 FlipSideView 和另一个 UINavigationController

Question

我正在尝试使用这种架构开发一个应用程序（游戏）：

• 主视图是一个基于导航控制器的导航栏隐藏
• 在主视图中我需要一个简单的信息 按钮显示选项/制作人员名单 Flipsideview
• 这个 Flipsideview 必须有另一个 带有右栏的导航控制器 按钮到“完成”系统按钮

问题是 Flipsideview 不显示完成按钮，它似乎显示主导航控制器...

这是代码。

AppDelegate：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    // Override point for customization after application launch.
    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];
    return YES;

}

主视图（从 XIB 加载）。仅提取 showInfo：

-(IBAction) showInfo:(id)sender {

    FlipSideViewController *controller = [[FlipSideViewController alloc] initWithNibName:@"FlipSideView" bundle:nil];
    controller.delegate = self;
    controller.title = @"Info";

    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
    navController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    navController.navigationBar.barStyle = UIBarStyleBlackOpaque;
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonItemStyleDone 
                                                                                target:controller action:@selector(done:)];

    navController.navigationItem.rightBarButtonItem = doneButton;
    controller.navController = navController;    
    [self presentModalViewController:navController animated:YES];

    [doneButton release];
    [controller release];
    [navController release];

}



- (void)flipsideViewControllerDidFinish:(FlipSideViewController *)controller {
    [self dismissModalViewControllerAnimated:YES];
}

FlipSideView。在 XIB 中，我只有一个空白视图，其出口链接到 UIViewController 视图。

@protocol FlipsideViewControllerDelegate;

@interface FlipSideViewController : UIViewController {

    id <FlipsideViewControllerDelegate> delegate;

    UINavigationController *navController;

}


@property (nonatomic,assign) id <FlipsideViewControllerDelegate> delegate;
@property (nonatomic,retain) UINavigationController *navController;

-(IBAction)done;

@end

@protocol FlipsideViewControllerDelegate
- (void)flipsideViewControllerDidFinish:(FlipSideViewController *)controller;
@end

}

实现文件...

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navController.navigationItem.title = @"Pippo";
}


    #pragma mark - User Methods

    - (IBAction)done {

        [self.delegate flipsideViewControllerDidFinish:self];

    }

结果是：

• 主视图显示没有导航 栏
• 单击信息按钮
• Flipsideview 显示动画 导航栏标题为“Info”而不是“pippo” 而不是右侧的“完成”按钮...

我哪里错了？

难道你在 FlipsideViewController 上没有得到两个带有 navigationItems 的 navigationBar 吗？我现在正在与这个错误作斗争。
