Formotion

Make this:

Complex data form

using this:

@form = Formotion::Form.new({
  sections: [{
    title: "Register",
    rows: [{
      title: "Email",
      key: :email,
      placeholder: "me@mail.com",
      type: :email,
      auto_correction: :no,
      auto_capitalization: :none
    }, {
      title: "Password",
      key: :password,
      placeholder: "required",
      type: :string,
      secure: true
    }, {
      title: "Password",
      subtitle: "Confirmation",
      key: :confirm,
      placeholder: "required",
      type: :string,
      secure: true
    }, {
      title: "Remember?",
      key: :remember,
      type: :switch,
    }]
  }, {
    title: "Account Type",
    key: :account_type,
    select_one: true,
    rows: [{
      title: "Free",
      key: :free,
      type: :check,
    }, {
      title: "Basic",
      value: true,
      key: :basic,
      type: :check,
    }, {
      title: "Pro",
      key: :pro,
      type: :check,
    }]
  }, {
    rows: [{
      title: "Sign Up",
      type: :submit,
    }]
  }]
})

@form_controller = Formotion::FormController.alloc.initWithForm(@form)
@window.rootViewController = @form_controller

And after the user enters some data, do this:

@form.render
=> {:email=>"me@email.com", :password=>"password", 
    :confirm=>"password", :remember=>true, :account_type=>:pro}

Installation

gem install formotion

In your Rakefile:

require 'formotion'

Usage

Initialize

You can initialize a Formotion::Form using either a hash (as above) or the DSL:

form = Formotion::Form.new

form.build_section do |section|
  section.title = "Title"

  section.build_row do |row|
    row.title = "Label"
    row.subtitle = "Placeholder"
  end
end

Then attach it to a Formotion::FormController and you're ready to rock and roll:

@controller = Formotion::FormController.alloc.initWithForm(form)
self.navigationController.pushViewController(@controller, animated: true)

Retreive

You have form#submit, form#on_submit, and form#render at your disposal. Here's an example:

class PeopleController < Formotion::FormController
  def viewDidLoad
    self.navigationItem.rightBarButtonItem = UIBarButtonItem.alloc.initWithBarButtonSystemItem(UIBarButtonSystemItemSave, target:self, action:'submit')
  end

  def submit
    data = self.form.render

    person.name = data[:name]
    person.address = data[:address]
  end
end

Why would you use form#on_submit? In case you want to use type: :submit. Ex:

@form = Formotion::Form.new({
  sections: [{
  ...
  }, {
    rows: [{
      title: "Save",
      type: :submit
    }]
  }]
})

@form.on_submit do |form|
  # do something with form.render
end

form#submit just triggers form#on_submit.

Data Types

Formotion current supports static and editable text, switches, and checkboxes.

Formotion::Form, Formotion::Section, and Formotion::Row all respond to a ::PROPERTIES attribute. These are settable as an attribute (ie section.title = 'title') or in the initialization hash (ie {sections: [{title: 'title', ...}]}). Check the comments in the 3 main files (form.rb, section.rb, and row.rb for details on what these do).

See the KitchenSink example for a bunch of options in action.

Forking

Feel free to fork and submit pull requests! And if you end up using Formotion in your app, I'd love to hear about your experience.

Todo

  • Not very efficient right now (creates a unique reuse idenitifer for each cell)
  • More data entry types (dates, etc)
  • More tests
  • Styling/overriding the form for custom UITableViewDelegate/Data Source behaviors.
  • Custom cell text field alignments
