PresentModalViewController: Animated: Crash after dismissal

I am currently having a problem with UIViewController

presentModalViewController:animated:

.

I am using the following code to set up and display a modal controller:

UINavigationController *navigationController = [[UINavigationController alloc] init];
AddSerialController *serialController = [[AddSerialController alloc] initWithNibName:@"AddSerial" bundle:nil];
[navigationController pushViewController:serialController animated:NO];

[self.parentViewController presentModalViewController:navigationController animated:YES];

[serialController release];
[navigationController release];

      

The app (running in the iPhone Simulator) crashes as soon as it is called dismissModalViewControllerAnimated:

. GDB says it crashes with objc_msgSend

.

If I comment out the last line of code (release of the navigation controller) everything works, but I am leaking UINavigationController

(as expected).

What the hell is going on here?

When you create a UINavigationController, you must give it a root view controller:



AddSerialController *serialController = [[AddSerialController alloc] initWithNibName:@"AddSerial" bundle:nil];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:serialController];

[serialController release];

[self.parentViewController presentModalViewController:navigationController animated:YES];

[navigationController release];
