164 PointsSeparate view layer? I don't get it.
I'm confused as to how the view layer is separate from the view controller. I realize that, in this case, the storyboard makes up the view layer, but when you walked through the example of creating the button programmatically, you added that code in the view controlled class. How does this keep the view separate from the view controller?
If you wanted to code the view programmatically instead of using the drag-and-drop storyboard, would you create a view class? Not sure how this would look.
Any thoughts?
Is there a way to see the code that underpins the storyboard?

Treehouse Guest TeacherA storyboard is an XML file that contains a list of views and controls along with the size and positioning. The SDK parses the XML and draws the relevant views on screen. You can either take advantage of interface builder or do it all on your own in code.

164 PointsYes, clearly. My question is: in the MVC model where does the "view code" go. In your example in the video you put it in the view controller class.
What's best practice?

Treehouse Guest TeacherIt all depends. If all you are doing is adding a couple of controls then adding it to the view controller is fine. If you are creating a complex view that could be reused then you would create your own custom class that would subclass UIView and layout all its subviews. Back in your view controller you would add that custom view as a subview in your view controller. You are not violating MVC by adding views in your view controller. You will certainly be violating MVC if you are creating an entire view layout in your view controller. Hope that makes sense.
