RubyMotion class extensions I use a lot

OTGHelpers

A set of class extenstions I commonly use in my applications for RubyMotion.

Current additions:

UILabel

auto_height_for_width(change_width=false)

Automatically resizes a UILabel's height based on its contents. Optionally, it can shrink the width as well.

NSString

uiimage

Runs UIImage.imageNamed(self) for the string.

nsurl

Returns the string as an NSURL

UIView

add_borders(locations, color, width = 1) aliased as add_border

Adds borders in specified locations on a UIView. Possible locations are: [:top, :left, :right, :bottom] and can be passed singularly or in an array.

add_top_border(color, width)

add_right_border(color, width)

add_bottom_border(color, width)

add_left_border(color, width)

These methods are used by the add_borders method and can be called independently if needed.

remove_borders aliased as remove_border

Removes all borders you've added on a UIView (may also remove other things you've added to the view's layer, so be careful with this one!)

UIImage

pad_to(size, args={})

Pads the size of an image to the specified size.

template

Returns a UIImage with UIImageRenderingModeAlwaysTemplate

Installation

Add this line to your application's Gemfile:

gem 'OTGHelpers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install OTGHelpers
