I'm wondering how Apple implemented the UINavigationItem that contains an activity indicator (see attached image below), above the title. Is this Apple's private API that allows to do that? If not, how can it be reproduced in an application. http://img218.imageshack.us/img218/8819/img0133g.png Thanks! ...

Hi I am developing an iphone app using camera. How to skip preview mode in imagePickerController? This mode asks whether to use or retake.
