Answer 1

Check the question How to handle different orientations in iOS 6. See the answer there for a project example of exactly what you need.

Basically you need to embed a custom navigation controller in your viewcontroller (the one you want to rotate). Add the following method in this custom navigation controller (it is for landscape orientation but you can replace it for portrait)

- (NSUInteger)supportedInterfaceOrientations
{
    return self.topViewController.supportedInterfaceOrientations;
}

and add to your view controller that should rotate:

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

Be sure Portrait, Landscape Right and Landscape Left orientations are enabled in your project. Then, if you want to block some orientations for a particular view:

– application:supportedInterfaceOrientationsForWindow:

Answer 2

Based on my understanding of the question I assume that you want the 2nd view controller to be portrait and the first view controller to be landscape.

For the second viewcontroller, add this method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

For the first view controller:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscape);

}
