Не показывал UINavigationController на modalView

Question

Я спрашиваю

[self presentModalViewController:searchRegionController animated:YES]; 

после этого я пытаюсь добавить NavigationController с помощью

   self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Add" style:UIBarButtonItemStyleBordered target:self action:@selector(next:)] autorelease];
    self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelAdd:)] autorelease]
    self.navigationItem.titleView =  someView;

Answer 1

так вот так в классе searchRegionController

-(void)viewDidLoad
{
     UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[self.view addSubview:naviBarObj];
UIBarButtonItem *rightBarButtonItem =[[[UIBarButtonItem alloc] initWithTitle:@"Add" style:UIBarButtonItemStyleBordered target:self action:@selector(next:)] autorelease];

UIBarButtonItem *leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelAdd:)] autorelease];

UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Navigation Title"];
navigItem.rightBarButtonItem = rightBarButtonItem;
navigItem.leftBarButtonItem = leftBarButtonItem;
naviBarObj.items = [NSArray arrayWithObjects: navigItem,nil];
}

надеюсь, это поможет.

Answer 2

Попробуйте:

-(void)someAction
{
ViewController *object = [ViewController]alloc]initWithNibName:@"NibName" bundle:[NSBundle mainBundle];

UINavigationController *navController = [UINavigationCOntroller]alloc]initWithRootViewController:object];

[self presentModalViewController:navController animated:YES];

[object release];
[navController release];
}

И в viewDidLoad ViewController выполните:

 self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Add" style:UIBarButtonItemStyleBordered target:self action:@selector(next:)] autorelease];
    self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelAdd:)] autorelease]
    self.navigationItem.titleView =  someView;
