Custom cell

[grimmwerks]

What's the correct way of creating a custom cell? I've made one that lays out and styles properly in red potion but when it scrolls out of and returns into view the layout is all messed up.

Could you please show the code of your cell ?

Sure - I tried a couple of ways - first as your docs showed, then trying to get the redraw via the value, seeing if applying style would fix it:

REALLY appreciate the assist; if it's something really stupid I'm doing.

...also very curious if you can create your own class for a section, or at least add buttons in a footer of a section. I'm sure at worst I could just use a cell for one item to add buttons to manipulate other areas but still curious.

Thanks for jumping in on slack; Mark's example was fantastic; just for others I'm pasting in what seems to work for me (which is exactly what you have in the docs; I'm unsure why it was a problem for me to begin with):

class StrapCell < PM::XLFormCell
  attr_accessor :position, :tension, :name
  attr_accessor :strap_name, :strap_position, :strap_tension

  include StrapCellStylesheet

  def initWithStyle(style, reuseIdentifier: reuse_identifier)
    super.tap do
      create_cell_items
    end
  end

  def create_cell_items
    @strap_image ||= append!(UIImageView, :strap_image)
    @strap_name ||= append!(UILabel, :strap_name)
    @strap_position ||= append!(UILabel, :strap_position)
    @strap_tension ||= append!(UILabel, :strap_tension)

    apply_style :strap_cell

  end

  def update
    super
    self.data_cell ||={}

    # create_cell_items

    @strap_name.text = value[:strap]
    @strap_position.text = "Position: #{value[:position]}"
    @strap_tension.text = "Tension: #{value[:tension]}"

  end

end

@grimmwerks Glad to hear that.

Could I ask you to PR a section on the doc for cells when using RedPotion ?

[grimmwerks]

Sure thing; I'm going to be doing a number of different custom cells / styling sections, so once I figure out a few things I definitely will!
