In iOS 6 shouldAutorotateToInterfaceOrientation没有用,但它在iOS 5.0或中工作正常5.1.

            _previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
            break;

        case UIInterfaceOrientationLandscapeLeft:
            nAngle = 0;
            bRet = YES;
            //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
