Custom ProMotion TableCell not showing

Question

I'm building a tableView with custom cells using RubyMotion and ProMotion. I can't figure out why none of the cells are visible. When I'm not trying to use the custom cell class, the title label is visible. What am I missing here? Thanks! Here is my code:

The TableScreen

class HomeScreen < PM::TableScreen
  title 'Overview'

  def on_load
    @welcome_label = UILabel.new
    @welcome_label.text = 'Welcome to PushUp'
  end

  def table_data
    data1 = [1, 2, 3]
    data = [{ number: 1, date: '1.2.2014' }, { number: 5, date: '2.2.2014' }]

    [{
        title: 'PushUps',
        cells:
                   data.map do |e|
                     { cell_class: MyCell, title: e[:anzahl].to_s, date: e[:datum] }
                   end
     }]
  end
end

The custom cell:

class MyCell < PM::TableViewCell
  attr_accessor :title, :detail

  def layoutSubviews
    @title = newTitleLabel
    @detail = newDetailLabel
    addLabelsToSubview
  end

  def addLabelsToSubview
    Motion::Layout.new do |layout|
      layout.view self.contentView
      layout.subviews "title" => title, "detail" => detail
      layout.vertical "|[title]|"
      layout.vertical "|[detail]|"
      layout.horizontal "|-[title]-10-[detail]-|"
    end
  end

  def newTitleLabel
    label = UILabel.alloc.init
    label.font = UIFont.preferredFontForTextStyle(UIFontTextStyleHeadline)
    label
  end

  def newDetailLabel
    label = UILabel.alloc.init
    label.font = UIFont.preferredFontForTextStyle(UIFontTextStyleFootnote)
    label
  end
end

Update

Really weird, when I raked this morning, the cell showed 2 labels. They are both sitting on the left, I think it' some kind of standard iOS cell design, so it's not created by me. But they have the values I gave them.

I then deleted everything from the cell class unless the initWithStyle method (call to super and returning self inside it stayed). The cell stayed the same. This means my cell design has no influence on the design of the cell. Have I maybe failed to declare the cell class the correct way? Thanks!

It appears you're doing the ProMotion part correctly. What version of PM are you using?

Some debugging steps:

1. Comment out everything inside your MyCell and see if it shows the title.
2. If so, then you're doing something wrong with MotionLayout.
3. If it still doesn't work, then it's a PM bug and you can file an issue.

I have a feeling your issue is with MotionLayout, not ProMotion.
