第二次加载时自定义UIImagePickerController问题(Customized UIImagePickerController issue when loaded a second time)

 我已经制作了一个带有自定义叠加视图的UIImagePickerController，以便增强界面，并且在我第一次加载它时效果很好，它非常完美。 问题是如果我解雇它然后再显示它我有一个奇怪的错误。 摄像机视图和叠加层显示在导航栏和前一个视图控制器的TabBar后面。 
 
 我尝试了不同的实现方法，但我无法解决这个问题。 
 
 这是我如何调用我的UIImagePickerController。 它的灵感来自这个示例代码 。 
 
[self.cameraOverlayViewController setupImagePicker:UIImagePickerControllerSourceTypeCamera];
[self presentModalViewController:self.cameraOverlayViewController.imagePickerController animated:YES];
 
 拍完照片后，我解雇了UIImagePickerController： 
 
[self dismissModalViewControllerAnimated:YES];
 
 绝对没有什么特别的实施方式。 
 
 这里有两个截图：

 谢谢你的回答！ 

I have made a UIImagePickerController with a custom overlay view in order to enhance the interface and it's working great the first time I load it, it's perfect. The problem is that if I dismiss it and then shows it again I have a strange bug. the camera view and the overlay appear behind the NavBar and the TabBar of the previous view controller.
 
I have try different ways of implementing this but I can't get this bug solved.
 
Here is how I call my UIImagePickerController. It's inspired by this sample code.
 
[self.cameraOverlayViewController setupImagePicker:UIImagePickerControllerSourceTypeCamera];
[self presentModalViewController:self.cameraOverlayViewController.imagePickerController animated:YES];
 
Once my picture taken, I dismiss the UIImagePickerController:
 
[self dismissModalViewControllerAnimated:YES];
 
Definitly nothing special in the way of implementing it.
 
And here 2 screenshots:
