Here's A handy helper for showing loading cells in iOS Apps with Rubymotion

To use, simply include the class in your project and then from within your controller:

# in my controller

def tableView(tableView, cellForRowAtIndexPath: indexPath)
  # return a loading cell
 LoadingCell.loadingCellWithTableView(self.tableView)

    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)
    @window.rootViewController = ExampleViewController.alloc.init

    @window.makeKeyAndVisible
    true
  end

Using Obj-C with MacRuby/Rubymotion

This little post aims to help you to translate Objective-C Blocks into Ruby blocks. Let's start by taking a look at few examples of iOS API call where blocks are used for animations and enumeration

Ruby Lambda Syntaxes:

Im Rubymotion and MacRuby you can use all the Ruby Lambda syntaxes that are:

block = lambda { |param|  ... }
