2. What’s RubyMotion
We can develop the iOS App and OSX App
with ruby(MacRuby)
We can write spec with bacon like a RSpec
Fully compile to machine code from ruby code
The license is $199.99(renewal $99)

3. How To Create App
・Create application window
・Create view controller
・Add label and button to view
・Add button action

4. Create your project

5. Create application
window
In Obj-C, The methods name are too long,
but RubyMotion is expressing with selector
in MacRuby

6. Create view controller
In loadView, we have to
prepare for views
(includes some button).
With using BubbleWrap
gem, we can add button
action like a `blocks`
that literal is added
Obj-C 2.0.
And also, we can use
method chain!!

7. Run your app!
$ rake

8. How To Write Spec
Almost of all user
action can be
worked out!
(ex. tap, drag,
pinch in/out...)
We can check the values of
view and some instance values

9. Run your specs!
$ rake spec
While running specs,
the simulator actually works
automatically. It’s pretty cool!

10. Collaborate with
Travis CI
【.travis.yml】
language: objective-c
before_install:
- (ruby --version)
script: "(bundle install) && (bundle exec rake clean) && (bundle
exec rake spec)"
