motion-encodable

Implement NSCoding protocol methods with ease for RubyMotion.

Installation

Add this line to your application's Gemfile:

gem 'motion-encodable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install motion-encodable

Usage

class Entry
  include Motion::Encodable
  properties :title, :body
end

Now, you can serialize and deserialize your object using NSCoding protocol.

entry = Entry.new
entry.title = 'foo'
entry.body = 'bar'

# save to NSUserDefaults
user_defaults = NSUserDefaults.standardUserDefaults
user_defaults[:entry] = entry.to_data

loaded_entry = Entry.load(user_defaults[:entry])
loaded_entry.instance_variable_get('@title') # => "foo"
loaded_entry.instance_variable_get('@body') # => "bar"

# save to file
dir_path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, true)[0]
file_path = dir_path + '/entry.dat'
entry.save_to_file(file_path)

loaded_entry = Entry.load(NSData.dataWithContentsOfFile(file_path))
loaded_entry.instance_variable_get('@title') # => "foo"
loaded_entry.instance_variable_get('@body') # => "bar"
