Hide FBFriendPickerViewController navbar when pushing onto UINavigationController

Question

Presenting an instance of `FBFriendPickerViewController` using `presentViewController:animated:completion:` is pretty straightforward and the class seems like it is meant for that use case. However, I want to push an instance of `FBFriendPickerViewController` onto an instance of `UINavigationController` using `pushViewController:animated:`. Consider the following code as an example: ``` self.fbFriendPickerController = [[FBFriendPickerViewController alloc] init]; self.fbFriendPickerController.hidesBottomBarWhenPushed = YES; // configure stuff [[self navigationController] pushViewController:self.fbFriendPickerController animated:YES]; ``` However, the problem is that the instance of `FBFriendPickerViewController` already has a top navigation bar. When pushed onto a `UINavigationController`, this results in two top navigation bars stacked vertically, as you can see in the screenshot below.

```
self.fbFriendPickerController = [[FBFriendPickerViewController alloc] init];
self.fbFriendPickerController.hidesBottomBarWhenPushed = YES;
self.fbFriendPickerController.doneButton = nil;
self.fbFriendPickerController.cancelButton = nil;
// configure stuff

[[self navigationController] pushViewController:self.fbFriendPickerController animated:YES];
```
