Adding subview to UIImagePickerController while picker.showsCameraControls = YES; (?)

Question

I'm trying to set up a a view that contains a button on top of UIImagePickerControllerView. I've seen it's possible to build an overlayView view setting picker.showsCameraControls = NO; and adding subview to the Overlay. But I don't want to lose the controllers, just to add a button on top. Is this possible?

Here my code:

if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
{
    UIImagePickerController *imagePickerCam =
    [[UIImagePickerController alloc] init];
    imagePickerCam.delegate = self;
    imagePickerCam.sourceType =
    UIImagePickerControllerSourceTypeCamera;
    imagePickerCam.mediaTypes = [NSArray arrayWithObjects:
                                 (NSString *) kUTTypeMovie,
                                 nil];
    imagePickerCam.allowsEditing = NO;

    UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
    UIButton *Button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [Button setFrame:CGRectMake(200, 480, 80, 80)];
    [Button addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside];
    [overlayView addSubview:Button];

    [imagePickerCam.view addSubview:overlayView];
    [overlayView bringSubviewToFront:imagePickerCam.view];

    [self presentModalViewController:imagePickerCam
                            animated:YES];
}

I'm trying this:

 [imagePickerCam.view addSubview:overlayView];
 [overlayView bringSubviewToFront:imagePickerCam.view];

Of course, it doesn't work. Any idea?

First thing, you should use :

[imagePickerCam setCameraOverlayView: overlayView];

This way, you won't have to manage the order of the subviews, so you can remove the line :

[overlayView bringSubviewToFront:imagePickerCam.view];

which, by the way, should have been the other way around :

[imagePickerCam.view bringSubviewToFront:overlayView];

Secondly, your overlay view has a height of 480, an you set you UIButton y offset to 480, so the button is out ouf bounds. Try something like :

UIView *overlayView = [[UIView alloc] initWithFrame:self.view.frame];
UIButton *Button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[Button setFrame:CGRectMake(200, self.view.frame.size.height - 80, 80, 80)];
