IPhone : migrating contents to UIScrollView in xcode iOS

I am a beginner and I am a bit confused about UIScrollView. Here is my case.

Without UIScrollView, I added and made stuffs on UIViewController.

Later on, I realized I have to implement UIScrollView, and now I have to migrate all my contents to inside of the UIScrollView.

If I drag out UIScrollView from storyboard and move all my elements into that scrollview,

I am guessing the order of contents would be:

from: UIViewController -> IBOutlets

to: UIViewController -> UIScrollView -> IBOutlets

Thus, do I have to change the way I access IBOutlets on my view controller?

Will this be the correct way?

before:

@property (strong, nonatomic) IBOutlet UILabel *coursenameLabel;

and access:

_coursenameLabel.text = @"text";

after:

@property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
@property (strong, nonatomic) IBOutlet UILabel *coursenameLabel;

and access like this?

_scrollView.coursenameLabel.text = @"text";

Would this be the simplest way to move all my contents to inside of UIScrollView?
