modalView를 사용하여 탐색 바에 barButton 추가 iphone

Question

내 응용 프로그램에서는 modalViewController 위에 탐색 막대가 표시되지만 navigatiobar에 barbutton을 추가 할 수는 없습니다. 나는 다음과 같은 코드를 사용하고 있습니다 :

편집 : 사전에

displayController = [[UIViewController alloc]initWithNibName:nil bundle:nil]; 

UINavigationController *cntrol = [[UINavigationController alloc] initWithRootViewController:displayController]; 

[displayController setTitle:@"TEST"]; 


UIBarButtonItem *submit = [[UIBarButtonItem alloc] 
          initWithBarButtonSystemItem:UIBarButtonSystemItemDone 
          target:self 
          action:@selector(displayViewForPosts)]; 

displayController.navigationItem.rightBarButtonItem = submit; 
[submit release]; 

UIBarButtonItem *newsfeed = [[UIBarButtonItem alloc] 
          initWithBarButtonSystemItem:UIBarButtonSystemItemDone 
          target:self 
          action:@selector(displayViewForPosts)]; 
displayController.navigationItem.leftBarButtonItem = newsfeed; 
[newsfeed release]; 

[self presentModalViewController:cntrol animated:YES]; 
[cntrol release]; 
[displayController release]; 

고맙습니다.

UIViewController *detailViewController = [[UIViewController alloc] initWithNibName:nil bundle:nil]; 

UINavigationController *cntrol = [[UINavigationController alloc] initWithRootViewController:detailViewController]; 

[detailViewController setTitle:@"TEST"]; 


UIBarButtonItem *submit = [[UIBarButtonItem alloc] 
          initWithBarButtonSystemItem:UIBarButtonSystemItemDone 
          target:self 
          action:@selector(displayViewForPosts)]; 
detailViewController.navigationItem.rightBarButtonItem = submit; 
[submit release]; 


[self.navigationController presentModalViewController:cntrol animated:YES]; 
[cntrol release];
