View Controller.mで次のコードを使用して、モーダルコントローラーを起動すると言いましたが、うまくいくようです。

- (void)viewDidLoad 
{
    NSArray *segmentContent = [NSArray arrayWithObjects:
                               NSLocalizedString(@"view 1", @""),
                               NSLocalizedString(@"view 2", @""),
                               NSLocalizedString(@"Close", @""),
                               nil];
     //or images insted of text
     //NSArray *segmentContent = [NSArray arrayWithObjects:
        //                          [UIImage imageNamed:@"pic.png"],
        //                          [UIImage imageNamed:@"spic.png"],
        //                          [UIImage imageNamed:@"close.png"],
        //                          nil]];


    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentContent];
    segmentedControl.selectedSegmentIndex = UISegmentedControlNoSegment;
    segmentedControl.momentary = YES; // option
    segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    segmentedControl.frame = CGRectMake(0, 0, 160, 30);
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    UIBarButtonItem *segments = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
    [segmentedControl release];
    self.navigationItem.rightBarButtonItem = segments;
    self.navigationItem.title = @"My title";
    [segments release];

次に、選択時のアクションを追加します。最後のアクションは、モーダル コントローラーを起動した場合の close ステートメントです。

- (IBAction)segmentAction:(id)sender
{
    UISegmentedControl *segmentedControl = (UISegmentedControl *)sender;
    switch ([sender selectedSegmentIndex])
    {
        case 0: 
        {   



// Do stuff like launch a modal controller. But don't forget to add this all into your modal controller views to get back out :)
InfoViewController *infoViewController = [[InfoViewController alloc] initWithNibName:@"InfoViewController" bundle:nil];
            UINavigationController *aInfoViewController = [[UINavigationController alloc] initWithRootViewController:infoViewController];
            [self presentModalViewController:aInfoViewController animated:YES];


        break;
    }
    case 1: 
    {



// do stuff



break;
    }
    case 2: 
    {
        [self.parentViewController dismissModalViewControllerAnimated:YES];         
        break;
    }
}
NSLog(@"Segment clicked: %d", segmentedControl.selectedSegmentIndex);
}

この方法でモーダルを閉じる必要がある場合は、以下の方法を使用します。

- (IBAction)dismissAction:(id)sender
{
    [self.parentViewController dismissModalViewControllerAnimated:YES];
}

同じそれぞれの h ファイルでアクション/メソッドを宣言することを忘れないでください。

- (IBAction)dismissAction:(id)sender;

お役に立てれば。
