I have already created UITableViewController embedded in Navigator Controller using Storyboard and Interface Builder.
I would like to display this UITableViewController programmatically from a different UIViewController that I already have.
how to do that?
You really should read the View Controller Programming Guide for iOS.
In particular, read about container view controllers (like
UINavigationControllersand how to push new view controllers onto its stack) and presenting view controllers temporarily (which describes how to present a modal view controller).
