Question

I’m new for storyboard file in iOS.

As I know, the objects (view controller object included) that I drag into the storyboard are existing instances, not a virtual class.

However, who owns those instances in application? AppDelegate? or others?

Now I’m trying to get a controller object from storyboard file and make the view of that controller shown with popover. (I don’t want to drag the relation lines among the objects completely, and use -addSubView: to implement all the sub-objects in popover view.) I think there must be a way to access the independent controller in stroyboard file.

Any suggestions?

If I implement the view controller in MyViewController class and init a new object with [MyViewController new], this would be another object that’s not I want, I think.

From within your view controller you can access the storyboard and instantiate the new view controller:

NewViewController *newVC = [self.storyboard instantiateViewControllerWithIdentifier:@"MyNewViewController"];

You may then use this in your popover.
