问题
I'd like to make customizations to a UIImagePickerController that allow the user to select a photo from one of their photo albums. I was wondering if the following is possible and if so, how it's accomplished:
1) Change the color of the navigation bar on the "Photo Albums" view and the view that appears after a photo album is selected.
2) Edit the buttons and their actions on both of the views.
3) Add a toolbar to the bottom of both image picker views.
Thanks in advance.

Well, it seems I've found a solution. If you implement the following navigation controller method:
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
}
It will give you access to the navigational controller that controls the picker, and also will send a pointer to each view controller that appears. So I believe with those two items, you can manipulate whatever you please.
