## iPhone Apps, Ruby-style

ProMotion is a RubyMotion gem that makes iOS development more like Ruby and less like Objective-C.
It introduces a clean, Ruby-style syntax for building screens that is easy to learn and remember and
abstracts a ton of boilerplate UIViewController, UINavigationController, and other iOS code into a
simple, Ruby-like DSL.

# Changelog

## Version 2.1.0

This release includes a few minor new features, but mainly it's a bugfix release and upgrading should go smoothly.

* Added `hide_nav_bar` option to screen init args
* `update_table_data` can now take `index_paths:` array to selectively update cells
* Table cell `style` has been changed to `properties`. `style` will persist as an alias for backwards-compatibility

# API Reference

We've created a comprehensive and always updated wiki with code examples, usage examples, and API reference.
