How to force a UIViewController to Portrait orientation in iOS 6

Question

As the ShouldAutorotateToInterfaceOrientation is deprecated in iOS 6 and I used that to force a particular view to portrait only, what is the c

Answer 1

I have a relatively complex universal app using UISplitViewController and UISegmentedController, and have a few views that must be presented in Landscape using presentViewController. Using the methods suggested above, I was able to get iPhone ios 5 & 6 to work acceptably, but for some reason the iPad simply refused to present as Landscape. Finally, I found a simple solution (implemented after hours of reading and trial and error) that works for both devices and ios 5 & 6.

Step 1) On the controller, specify the required orientation (more or less as noted above)

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

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    NSInteger mask = UIInterfaceOrientationMaskLandscape;
    return mask;

}

Step 2) Create a simple UINavigationController subclass and implement the following methods

-(BOOL)shouldAutorotate {
        return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
        return UIInterfaceOrientationMaskLandscape;
}

Step 3) Present your viewController

vc = [[MyViewController alloc]init];
MyLandscapeNavigationController *myNavigationController = [[MyLandscapeNavigationController alloc] initWithRootViewController:vc];
[self myNavigationController animated:YES completion:nil];

Hope this is helpful to someone.
