What is a Section?

"Section" is something like "partial" which you may know from RubyOnRails. In the first look it's just a list of elements which will be added to the "Screen". But the magic is inside. When you add "Element" to a "Section", e.g. image or label, it will try to draw it using CALayer/CGContext/etc, instead of adding new UIView. That way increases application speed (especially on Table elements) by 5-10 times.

Let's get started.

¶

Create a section.

Just inherit it from Prime::Section.
```
class FooSection < Prime::Section
end
```
¶

Add some elements to the section.

Each element should have name and type: "image", "label", "button", etc. When you send :text option, type will be "label" by default. When you send :image option, type will be "image" by default.
```
class FooSection < Prime::Section
  element :welcome, text: 'Hello World!'
  element :avatar, image: 'images/users/avatar.jpg'
  element :cheer, type: :button
end
```

Render Section in Screen

NOTE: You must send "screen" option on section initialization.

class FooScreen < Prime::Screen
  def render
    @main_section = FooSection.new(screen: self)
    @main_section.render
  end
end
