Yesterday I mentioned a user interface control based on the audio trimmer control found in the iPhone voice memos app.

One of the elements of that audio trimmer control is a popover that appears over the edge of the selected area, and here’s a library from Nyvra allowing you to add a similar element to a UISlider.

This library comes in the form of a UISlider category so you can easily attach it to an existing UISlider and adds a popover illustrating the current value the slider is set at.

Here’s an image showing the category in action:

You can find NYSliderPopover on Github here.

A nice simple and useful add-on.
