Reverse engineering iOS weather app UI components

I am trying to write down a summary of the iOS weather App. The main components that I am interested are labelled in the image below as 1, 2, 3, 4 and 5.

The UI should be obtained as following:

A ViewController with:

• 1 - is a UILabel


• 2 - is a UIButton that changes either text or gets hidden to display a 2nd button


• 3 - UIScrollView with horizontal scroll? I guess it has custom cell types.


• 4 - Same as above but vertical cells.

And a PageView controller (5).

Storyboard creation (would like to follow this):

• 1-4 - belong to the same ViewController


• 5 - is above this hierarchy.

Doubts:

• Is my interpretation correct?


• Are 3/4 vertical view controllers?


• Is there any disadvantage in implementing this using interface/story builder?
