Storyboard "Main", but didn't get a UITableView when using UITableViewController
Try changing your super class to UIViewController or change the controller in your storyboard to TableView Controller
@interface MTViewController : UIViewController, UITableViewDataSource, UITableViewDelegate@end
Drag a new instance of Table View Controller into your storyboard, copy the cells you created in your previous controller into the new one.
This error occurred probably because you used the default UIViewController created by XCode which isn't a UITableViewController.
