iphone-将摄像机显示为背景，顶部为OpenGLES模型

嗨，我很难将Iphone的4摄像机设置为背景，也很难在上面画出简单的立方体。实现这一目标的最佳方式是什么？我的项目结构很简单，我在委托中使用了opengl类，它完美地绘制了立方体，而控制器并没有做太多工作

因此，相机控制器是下面的代码，需要在opengl视图类中设置，但它不起作用

UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.navigationBarHidden = YES;
imagePicker.toolbarHidden = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.showsCameraControls = NO;
imagePicker.cameraOverlayView = self;

// The 54 pixel wide empty spot is filled-in by scaling the image.
// The camera view's height gets stretched from 426 pixels to 480 pixels.

float bandWidth = 54;
float screenHeight = 480;
float zoomFactor = screenHeight / (screenHeight - bandWidth);

CGAffineTransform pickerTransform = CGAffineTransformMakeScale(zoomFactor, zoomFactor);
imagePicker.cameraViewTransform = pickerTransform;

m_viewController = [[UIViewController alloc] init];
m_viewController.view = self;
[m_viewController presentModalViewController:imagePicker animated:NO];

有什么建议吗
