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
Im Rubymotion and MacRuby you can use all the Ruby Lambda syntaxes that are:
block = lambda { |param| ... }
| class AppDelegate | |
| def post_messages_firebase | |
| @_post_messages_firebase ||= "post_messages".fbase | |

| regex = /[\u{1f600}-\u{1f64f}]/ | |
| clean_text = str.gsub regex, '' |
