我正在使用 UIImagepickerController 从相机拍照。我通过使用cameraoverlayview 属性在相机视图上使用我自己的视图...我想在用户单击自定义视图中的按钮时从相机拍照...我正在使用以下代码

 - (void)viewDidLoad {

imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType =  UIImagePickerControllerSourceTypeCamera;
    [self presentModalViewController:imagePickerController animated:YES];   
    imagePickerController.showsCameraControls=NO;

imagePickerController.cameraOverlayView = self.customView;

}

- (IBAction) takePicture
{
    [imagePickerController takePicture];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

[picker dismissModalViewControllerAnimated:YES];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [self dismissModalViewControllerAnimated:YES];
}

，但是当我运行此代码时，它给了我错误

错误：FigCreateCGImageFromJPEG 返回 -12905。输入（空）为 773625 字节。

我还收到内存使用级别 2 和级别 1 的警告

，并且 imageView 中没有显示任何图像。任何人都可以帮助我，我可能做错了什么？顺便说一句，我使用的是安装了 iOS4.1 的 iPhone 3G
