  在viewDidLoad中使用此代码 .

  UINavigationBar *myBar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
  [self.view addSubview:myBar];
  

  这会在您的视图中添加导航栏 .

  这可能对你有帮助

  PopoverView *foo = [[PopoverView alloc] initWithNibName:@"PopoverView" bundle:nil];
   // Here you pass through properties if you need too.
   // ...
   UINavigationController *navC = [[UINavigationController alloc] initWithRootView:foo];
   [foo release];
  
   [self.navigationController presentModalViewController:navC animated:YES];
  

  这就是你向模态添加导航栏的方法 .

  [self.navigationController setNavigationBarHidden:NO animated:YES];
