iPad:Lock UIView orientation into Landscape mode only

Question

This requirement is for iPad. I have an UIView which used as Camera overlay view when launching video recording. It set in UIImagePickerController as below.

[self presentModalViewController:pickerController animated:NO];
pickerController.cameraOverlayView =myOwnOverlay;

This is my requirement that i have to provide my own overlay in UIImagePickerController when calling camera for video recording. I want to lock my own camera overlay UIView into LANDSCAPE mode only, so that allow user can record video in Landscape mode only and not in Portrait mode, this is also my project requirement. I know about shouldAutorotateToInterfaceOrientation which is used for UIViewController. I used "[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];" it, it locks to Landscape mode when i launch this camera own overlay UIView, but when i rotate the device, UIView also rotates to Portrait. I don't want Portrait mode at all. I tried to handle this issue like below, but its not working for UIView. Then i saw this is possible in UIviewController, but not in UIView. But i must to have UIView for this camera launch operation.

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

return (interfaceOrientation==UIInterfaceOrientationLandscapeRight || interfaceOrientation==UIInterfaceOrientationLandscapeLeft);
}

Please suggest me how can i provide solution for orientation lock for my UIView?

Thank you!

Doubt over allowing from APPLE but If you want the UIImagePickerController to start(and stay) in Landscape orientation use following code.

//Initialize picker

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
   picker.delegate = self;


//set Device to Landscape. This will give you a warning. I ignored it.
//warning: 'UIDevice' may not respond to '-setOrientation:'


[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

//Set Notifications so that when user rotates phone, the orientation is reset to landscape.
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

//Refer to the method didRotate:   
[[NSNotificationCenter defaultCenter] addObserver:self
              selector:@selector(didRotate:)
               name:@"UIDeviceOrientationDidChangeNotification" object:nil];

//Set the picker source as the camera   
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

//Bring in the picker view   
[self presentModalViewController:picker animated:YES];

The method didRotate:

- (void) didRotate:(NSNotification *)notification

{
      //Maintain the camera in Landscape orientation
 [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

}

Credit for This code belongs to UIImagePickerController in Landscape

but sometime app crash in didRotate Method – iBhavik Jul 31 '12 at 13:25 — iBhavik, Jul 31 '12 at 13:25

Try this:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 

{
    BOOL isLandscapeRight = (UIInterfaceOrientationLandscapeRight == interfaceOrientation);
    return isLandscapeRight;
}

And Also Have to set Your Applications info.plist's interface orientation to Landscape (right home button)
