    if (toInterfaceOrientation == UIInterfaceOrientationPortrait) {
        [previewLayer setOrientation:AVCaptureVideoOrientationPortrait];
    }
    else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
        [previewLayer setOrientation:AVCaptureVideoOrientationLandscapeLeft];
    }
    else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        [previewLayer setOrientation:AVCaptureVideoOrientationLandscapeRight];
    }
    else {
        [previewLayer setOrientation:AVCaptureVideoOrientationPortraitUpsideDown];
    }
}
