以模态方式呈现的表视图没有导航栏

Question

当我以模态方式呈现视图控制器时：

  

//以模态方式显示导航控制器。

     

[self presentModalViewController：theNavController animated：YES];

导航栏被弹出的视图遮住了！ 如何让导航栏不被遮盖？

提前致谢！

Answer 1

答案可在iPhone: Show modal UITableViewController with Navigation bar找到 和 UINavigationBar refuses to show in Modal View Controller！

您需要将UIViewController包裹在UINavigationController中，然后展示导航控制器：

AccountViewController* accountViewController = [[AccountViewController alloc] initWithNibName:@"AccountView" bundle:nil]; 
... 
// Initialize properties of accountViewController 
... 
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:accountViewController]; 
[self.navigationController presentModalViewController:navController animated:YES]; 
[navController release]; 
[accountViewController release]; 

Answer 2

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewContorller:someViewController];
[self presentModalViewController:navController animated:YES];
