iPad/iOS modalView jumps left on dismiss

Question

I added a modalView to my App, everything working fine, but on closing the modal, the whole modalView jumps about 1-2 centimeters to left while it disappears.

I did not find any reason for it yet, so here is the code regarding modal:

AppController:

- (void) showNameModal:(Player *)player 
{
    namesModal = [[PlayerModalView alloc] init];
    namesModal.delegate = self;
    namesModal.player = player;

    UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:namesModal];

    navCon.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:navCon animated:YES];

    [navCon release];
    [namesModal release];
 }

 - (void)didDismissModalView 
 {
    [self dismissModalViewControllerAnimated:YES];
 }

ModalView:

 - (void)dismissView:(id)sender 
 {
    [delegate didDismissModalView];
 }

called via navigation buttons as well ass via keyboard by

  [self dismissView:nil];

As you can see, there is nothing special in it, could be taken from a manual actually. What happens in detail:

Modal appears in center of screen, slides in from the bottom. centered all time. i can handle some actions in the modalView, it stays centered.

now, dismissing the view makes it jumping to the left, than slides out.

Since it's a forced landscape-right app (currently), I was only able to notify the left-jump.

Any ideas how to get this jumping away?

Thanks

The problem is that the UIViewController you're showing modally doesn't allow the orientation you're presenting it in, so when it disappears, it will do that in a direction that it considers "allowed".

Add this to the UIViewController for you modal view:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

Try this,

- (void)didmissView:(id)sender
{
   [self.navigationController didmissModelViewControllerAnimated:YES];
}

oki, that crashes the app, *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present a nil modal view controller.. so i guess i oversee something.. – thedanielhanke Sep 20 '10 at 11:54
I remember ModelView should dissmiss itself. The one who present the modelView has no responsibility to dismiss the modelView. But I feel strange, why does the one who present the modelView become nil ? – AechoLiu Sep 20 '10 at 21:41

You are not modally presenting an instance of PlayerModalView but rather a UINavigationController. The left jerk you see is most likely the default animation of the navigation controller attempting a slide transform to the (non-existant) previous view.

It doesn't sound like you need a navigation controller for the PlayerModalView. Instead, you should create an ordinary view controller for it.

the PlayerModalView actually should have a Navigation-Bar, therefore i`d choose a UINavigationController. However, what do you mean by "(non-existant)" ? – thedanielhanke Sep 21 '10 at 09:05
It turns out, that its an orientation problem. only on 3.2.2, 4.2 works fine. Simulatorresults differ completely from Hardware too.. Thank you a lot anyways! – thedanielhanke Sep 21 '10 at 09:43

This solution seems to work well: Modal View Controller with keyboard on landscape iPad changes location when dismissed

To simplify resigning the first responder (if finding it is difficult), you can just call

[self.view endEditing:YES];
[self dismissModalViewControllerAnimated:YES];
