Objective C -> RubyMotion
This is an active post where I update references and code snippets to quickly build app using RubyMotion. So lets start . . .
Changing background color
Objective-C
| 1 2 | [webView setOpaque:NO]; webView.backgroundColor = [UIColor clearColor]; |
Corresponding RubyMotion Code
| 1 2 | self.view.setOpaque(false) self.view.backgroundColor = UIColor.clearColor |

RubyMotion webview shell
To load a application in webview you can use following shell I have created.
https://github.com/akshatpaul/rubymotion-webview-shell
This shell is used create ios application for responsive urls
You require rubymotion tool chain installed on your system to use this shell.
Steps to create ios application in web view
- Step 1 (Install Dependencies)
- Inside cloned repository execute ‘bundle install’
- Step 2 (Add your URL)
- Goto main_controller.rb inside method viewDidLoad and replace url with desired url.
def viewDidLoad
self.view.loadRequest NSURLRequest.requestWithURL(NSURL.URLWithString("http://www.facebook.com"))
end
- Step 3 (Test application)
- execute ‘rake’ to test the application.
That’s it !
Enjoy.
