IOS Ignoring ModalPresentationStyle and ModalTransitionStyle and presenting fullscreen

Question

My App is completely ignoring UIModalPresentationFormSheet and UIModalTransitionStyleCrossDissolve. It is always popping up fullscreen and with the default transition.

It does it on my real app. I then made a blank test app, and it does the same thing.

It is quite simple: My AppDelegate loads KBViewController as the root view. KBViewController tries to present a blank view controller (KBModalViewController). The view in KBModalViewController.xib is set to the "FormSheet" Size

My View Controller:

@implementation KBViewController


-(void)viewDidAppear:(BOOL)animated{
    [self setModalPresentationStyle:UIModalPresentationFormSheet];
    [self setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
    KBModalViewController *m = [[KBModalViewController alloc] initWithNibName:nil bundle:nil];
    [self presentViewController:m animated:YES completion:nil];

    //Also tried the depreciated presentModalViewController, same result
    //[self presentModalViewController:m animated:YES];
}

I am using Xcode 4.61. I have compiled to ipad 5.1, ipad 6.1, and a real ipad 2 on 6.1. Same on all.

Try..

@implementation KBViewController


    -(void)viewDidAppear:(BOOL)animated{

        KBModalViewController *m = [[KBModalViewController alloc] initWithNibName:nil bundle:nil];
        [m setModalPresentationStyle:UIModalPresentationFormSheet];
         [m setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
        [self presentViewController:m animated:YES completion:nil];

        //Also tried the depreciated presentModalViewController, same result
        //[self presentModalViewController:m animated:YES];
    }
