iOS 7 doesn't show cancel button of search bar in navigation bar

Question

In an app that\'s supposed to run on iOS 6 and iOS 7, the cancel button of the search bar embedded in the navigation bar is not shown anymore if the app is run on iOS 7. On iOS

Answer 1

There are two options:

1. Add a search bar like a subview to uiviewcontroller.view and hide a navigation bar if needs
2. Add a cancel button to uiviewcontroller.navigationItem.rightBarButtonItem

my preference is the second one, but it looks more native with the first one.
