Can a UINavigationController contain a UITabbarController?

I want to have a UIView inside of a NavigationController that has 4 buttons. Clicking on any of these 4 buttons will push a UITabBarController 开发者_JS百科that contains a NavigationController with a respective UIView.

Is this possible? Tweetie seems to do something similar.

On my application, I have a tab bar view controller, then inside of that, I have navigation controllers going to individual views in my interface builder. I believe if you just copy this format, it will work.(-> means connected)

Tab Bar View Controller->4 separate Navigation Controller->ui views

I hope this helps
