iosiphone-4uiimagepickercontroller

Does anyone know how to enable the photo album button on the UIImagePickerController when its in the camera mode? Like how the camera app on on the iphone can toggle between image and video taking and also has the button to view the photo library?

This can be done via the following lines:

- (void) navigationController: (UINavigationController *) navigationController  willShowViewController: (UIViewController *) viewController animated: (BOOL) animated {
    if (imagePickerController.sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {
        UIBarButtonItem* button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(showCamera:)];
        viewController.navigationItem.rightBarButtonItems = [NSArray arrayWithObject:button];
    } else {
        UIBarButtonItem* button = [[UIBarButtonItem alloc] initWithTitle:@"Library" style:UIBarButtonItemStylePlain target:self action:@selector(showLibrary:)];
        viewController.navigationItem.leftBarButtonItems = [NSArray arrayWithObject:button];
        viewController.navigationItem.title = @"Take Photo";
        viewController.navigationController.navigationBarHidden = NO; // important
    }
}

- (void) showCamera: (id) sender {
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
}

- (void) showLibrary: (id) sender {
    imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
