ARToolkit，UIImagePickerController & cameraOverlayView:怎么拍照？

Question

我正在为iPhone和ARToolkit开发一个增强现实应用程序。现在，我想将它的功能包含在一个主应用程序中，其中有一个按钮，它会抛出一个“AR View”，以便能够在上面拍摄一张带有3D模型的照片。

我使用UIImagePickerController和cameraOverlayView将ARViewController视图添加到相机视图，作为一个覆盖，但它没有显示它。这是代码：

-(IBAction)Switch2AR:(id)sender{

ARController = [[ARViewController alloc] init];
[ARController loadView];

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


if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
else {
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
picker.showsCameraControls = YES;

picker.cameraOverlayView = ARController.view;


//[ARController.view addSubview: picker.view];
//[picker.view addSubview: ARController.view];

//[picker viewWillAppear:YES];
//[picker viewDidAppear:YES];
//[ARController viewWillAppear:YES];
//[ARController viewDidAppear:YES];


[self presentModalViewController:picker animated:YES];

[ARController release];

}

我还尝试将UIImagePickerController视图添加为ARViewController视图的子视图，但由于相机模态视图“隐藏”AR视图而无法工作。也是作为UIImagePickerController子视图的ARViewController视图。

问题是，我不能以任何方式覆盖我的ARView和照相机视图。

提前感谢

只要改变

picker.showsCameraControls = YES;

至

picker.showsCameraControls = NO;

而且它应该能工作。
