UIImagePickerController in landscape orientation

Question

I want the UIImagePickerController to start(and stay) in Landscape orientation code. I tried the solution as described here (http://stackoverflow.com/questions/2083672/uiimagepickercontroller-in-landscape)

//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];

}

But the solution does not work for iOS 4.0. The app doesnot respond when camera is launched in iOS 4.0. Can anyone suggest a work around to this?
