Take the 2-minute tour ×  I do this: First create navigation
based application. Then delete UITableView from
rootViewController.xib, add a UIView connect it to File's Owner.
Change UITableView to UIViewController in RootViewcontroller.h
Finally clean all methods of UITableView in RootViewcontroller.m
But when I run the project receives this error:
-[RootViewcontroller
tableView:numberOfRowsInSection:]:unreconized selector sent to
instance  What am I doing wrong?  share|improve this question

few possibility.    1. Make sure that UITableView protocol is
implemented in the header file. Eg @interface
TestingViewController : UIViewController <UITableViewDelegate,
UITableViewDataSource>    2. Check that your connection from in
the Interface Builder and make sure its linked properly
