UINavigationController Force Rotate

Question

My application is primarily portrait, however there is one view that REQUIRES a landscape orientation.

My views are contained within a UINavigationController, which

Answer 1

I had the same requirement for one of my applications!!!

luckily I found a solution!

In order to keep main viewcontroller landscape, no matter from what orientation it was popped/pushed, I did the following thing: (in viewWillAppear:)

//set statusbar to the desired rotation position
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationLandscapeLeft animated:NO];

//present/dismiss viewcontroller in order to activate rotating.
UIViewController *mVC = [[[UIViewController alloc] init] autorelease];
[self presentModalViewController:mVC animated:NO];
[self dismissModalViewControllerAnimated:NO];

P.S.Tested on sdk 3.2.5 ios 5.0.1.

P.S. On iOS 8 previous answer results some screen flickering and also - it is not stable (In some cases It does not work for me anymore.) So, for my needs, I changed the code to: (ARC)

//set statusbar to the desired rotation position
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationLandscapeLeft animated:NO];

[self.navigationController presentViewController:[UIViewController new] animated:NO completion:^{
    dispatch_after(0, dispatch_get_main_queue(), ^{
        [self.navigationController dismissViewControllerAnimated:NO completion:nil];
    });
}];

//I added this code in viewDidDissapear on viewController class, which will be popped back.

Hopefully it will help!
