NMRangeSlider

NMRangeSlider is custom iOS control that gives you a UISlider like UI for selecting a range of values. This project was inspried by: https://github.com/buildmobile/iosrangeslider.

The range slider can be configured using a set of images in much the same way as UISlider. (Background, Track and Thumbs)

In addition to the regular UISlider features it can:

Handle stepped values. The handles will snap to points along the slider with a couple different options
Access to the centre location of handle image. This can be used to arrange subviews.
(New) Disable lower handle so it behaves like a regular UISlider but still use other features.
(New) Set a negative min range so the thumbs can cross over. (with custom track image)
(New) Automatic iOS 7 theme with tint color support
(New) Vertical range slider

See the demo application for some examples on how the to configure the slider.

If anyone would like to help here a few things I would like to add:

Custom images for other control states. UISlider lets the user set different images for any number of UIControlStates.
Have a designer provide a few more sample graphics.
Ability to set a tint colour that is applied to the default images (or drawn using CoreGraphics)
