How to set device (UI) orientation programmaticall

Question

Would like everything on the screen (UI) to be able to rotate from landscape left to right or vica versa.

How do I go about doing this? Is this private?

I know that

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {}

lets you say which orientations the UI can be, but is there a way to force only one at a time?

Cheers

Answer 1

As suggested on a related thread shouldAutorotateToInterfaceOrientation is deprecated. Newer apps should leverage the following methods as described in Apple's UIViewController Class Reference until they themselves become deprecated:

• shouldAutorotate,
• preferredInterfaceOrientationForPresentation; and
• attemptRotationToDeviceOrientation.

From what I understand it's best to use different View Controllers for views which need to lock into (i.e. have a preferred) orientation mode which differs from the last.

Also this simple way works:

[[UIApplication sharedApplication] setStatusBarHidden:YES];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];

and back:

[[UIApplication sharedApplication] setStatusBarHidden:NO];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

Answer 3

Even though this is not an idle solution, works well for me.

- (void)viewDidLoad
{
   self.view.transform = CGAffineTransformIdentity;
   self.view.transform = CGAffineTransformMakeRotation((M_PI * (90) / 180.0)); 
   self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}

[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];

UIViewController *mVC = [[UIViewController alloc] init];

[self dismissModalViewControllerAnimated:NO];
