[REQ] Loaded View Symbol

[GantMan]

Caution

This may already exist in some way, and I'm not seeing it.

Current Behaviour

During a layout block you can specify a symbol of the loading UIView for styling.

class RootController < UIViewController
  stylesheet :root_style

  layout :root do
    #...
  end
end

This is great. Though it tightly couples the stylesheet to that particular layout block.

Request

I'm requesting a level of abstraction between the two. A special Teacup keyword that identifies the loading view.

EXAMPLE

Teacup::Stylesheet.new :root_style do

  style Teacup::LoadingView,
    backgroundColor: 'background'.uicolor

end

Benefit 1: Styles that import could abstract away application wide styles on the view. Like the above background pattern.

Benefit 2: Would make Teacup play nicely with other forms of loading (Like ProMotion) where the layout block is inaccessible and attributes would have to manually be set.

EXAMPLE the will_appear code could be removed and placed in the abstracted stylesheet.

class HomeScreen < PM::Screen
  stylesheet :home_screen

    def will_appear
      #the following line could be eliminated!
      set_attributes self.view, stylename: :home_view
    end
end

Follow Up

Please let me know if you have questions/concerns with this philosophy. I'd be more than happy to help if you could point me in the right direction of how you'd see this behavior implemented.

There's a lot going on in this one, especially the ProMotion integration concerns. It seems like there are more issues there, like making sure restyle! is called. For now anyway, I think just assigning a root class is appropriate... A project that shows an ideal "promotion+teacup" integration would be great, though, and would help me think about how this could be improved!

No big deal if you squash this one. Just dreamcode requests.
