After dismissModalViewController, view is in portrait mode

Question

I have a detail view where i load a help view with a button. I am using [UIViewController presentModalViewController:animated:]. In help view I am dismissing the view with a button. I am using [UIViewController dismissModalViewControllerAnimated:].

The problem is, after dismissing the help view, the detail view is in portrait mode, regardless of which orientation the device is in.

In all the view controllers, I have implemented shouldAutoRotateToInterfaceOrientation: and returned YES.

Answer 1

I think there are two selective solution

1.Officially available in iOS 5.0 and later, you can implement

/* call this method when your return value from shouldAutorotateToInterfaceOrientation: changes
 if the current interface orientation does not match the current device orientation, a rotation may occur provided all relevant view controllers now return YES from shouldAutorotateToInterfaceOrientation: */

+ (void)attemptRotationToDeviceOrientation

2.Use the trick from Canopus's Answer. It's pretty fine with iOS 4.3 and earlier BUT It's not guarantee solution that owner answer has warned you.

Hope it helps you!
