Icon font not applying in RubyMotion app - ios

Question

Having an issue trying to use an icon font for scalable icons in a RubyMotion (ios) app.
I created a small set of icons from icomoon, and set the characters to 'A', 'B', and 'C'.
I imported this into the Font Book and it appears to respect the 'A', 'B', and 'C' characters:
To test, I fired up a word document and typed 'A', 'B', and 'C' and it appears to display fine:
Now, onto the RubyMotion app - I included the font in /resources:
(Loading Lobster and Open Sans from sub-directories work)
Then I reference the font in my Rakefile:
Motion::Project::App.setup do |app|
# Use `rake config' to see complete project settings.
app.name = 'myapp'
app.fonts = ["OpenSans-Bold.ttf", "icomoon.ttf"]
end
In my controller, I add a label to the screen using the icomoon font:
#lblIcon = UILabel.alloc.initWithFrame([[0,0],[100,100]])
#lblIcon.text = "A"
#lblIcon.backgroundColor = UIColor.clearColor
#lblIcon.color = "#ffffff".to_color
ico_font = UIFont.fontWithName("icomoon", size:48)
#lblIcon.font = ico_font
self.view.addSubview #lblIcon
Now, when I run rake clean to force a refresh and rake to launch the simulator, the font doesn't seem to work:
If I use the RubyMotion inspector/REPL and drill down on the font, it say it is loading Helvetica, not icomoon as I intended:
I'm at a loss here on why I can't apply the icomoon font family and helvetica appears instead.
Any suggestions or ideas?

Answer 1

I have added my fonts in the 'resources' folder and successfully using them directly without manipulating app.fonts:
b.titleLabel.font = UIFont.fontWithName('Entypo', size: barHeight*1.1)
(the font I'm using is called Entypo.ttf)
Otherwise, the code you've pasted looks ok to me.
