New view controller in xcode?

Question

Here is my original question for adding a new view controller in xcode;

This is the code I observed, that loads out in a new project in Xcode for a view controller.h/m file

.h

@interface ViewController : UIViewController

{


}

@end

.m

@interface ViewController ()

@end

@implementation ViewController

But when I add a new class; I notice there is no 'UIViewController' object but instead there is an NSOBject.

.h

@interface Newclass : NSObject
@end

.m

@implementation Newclass
@end

My question; to successfully programmatically access a new view controller in x code story board, do your new custom .m/.h files have to be formatted as a UIViewController or does it matter.

Yes, to inherit the properties & methods a UIViewController needs it must be 'formatted' as (the correct term is 'inherit from') a UIViewController. So:

@interface Newclass : UIViewController
@end

and

@implementation Newclass
@end
