Question

I am using the following code to dismiss modal view controllers:

- (IBAction)done {
#ifdef __IPHONE_5_0
    if ([self respondsToSelector:@selector(presentingViewController)])
        [self.presentingViewController dismissModalViewControllerAnimated:YES];
    else
#endif
        [self.parentViewController dismissModalViewControllerAnimated:YES];
}

If I runt he simulator using iOS 4.3 iPad, it uses self.parentViewController and works fine. However, when I runt he simulator using iOS 6.0 iPad the simulator crashes right after the view is dismissed using self.presentingViewController.

I do not have an actual iPad to test on… any ideas?

EDIT:

below is the code that creates the modal view controller.

NSArray* errors = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Errors" ofType:@"plist"]];

UIViewController* vc;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    DocumentsViewController_iPad* docsVC = [[DocumentsViewController_iPad alloc] initWithNibName:@"DocumentsViewController-iPad" bundle:nil];
    docsVC.documents = errors;
    docsVC.errors = YES;
    docsVC.navTitle = @"Troubleshooting";
    vc = docsVC;
} else {
    DocumentsViewController* docsVC = [[DocumentsViewController alloc] initWithNibName:nil bundle:nil];
    docsVC.documents = errors;
    docsVC.errors = YES;
    docsVC.navTitle = @"Troubleshooting";
    vc = docsVC;
}

vc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:vc animated:YES];
[vc release];

A few things:

• Yes, you should use dismissViewControllerAnimated:completion: as @rdelmar said
• You should call it on presentingViewController, not parent
• You can skip going to the presenting controller and dismiss self, it will forward this message to the presenting controller if needed.
