Why is my app missing the UIImagePickerController cancel/preview/choose toolbar?

My app is not doing anything special with the UIImagePickerController. I'm allowing the user to pick from the camera if available or to pick from the photo albums otherwise.

I notice that there's no retake/use screen when using the camera, and there's no cancel/Preview/choose toolbar when picking.

I don't see how this is enabled in the documentation. There's n开发者_高级运维othing...

Was this an old feature that's now been removed in 4.2+? I notice the Messages app and WhatsApp both have these preview toolbars.

What am I missing? Thanks!

Here's an example project I whipped up. http://dl.dropbox.com/u/4153528/PickerTest.zip

It shows the problem...

Make sure that you haven't applied the UIButton (ExpandsVertically) category:

It can cause the buttons of the UIImagePickerController to disappear
