cucumber step for calabash-ios that scrolls a view until a name is match or a limit is reached

scroll-until.rb

Then /^I scroll (left|right|up|down) until I see "([^"]*)" limit (\d+)$/ do |dir,name,limit|
  if (not element_exists("view marked:'#{name}'")) 
    count = 0
    begin
      scroll("scrollView index:0", dir)
      sleep(STEP_PAUSE)
      count = count + 1
    end while ((not element_exists("view marked:'#{name}'")) and count < limit.to_i)
  end
end

I am novice ruby/gherkin programmer and I could use some help cleaning this step.
