On this site I occasional like to mention select open source ui components for improving the look of iOS apps such as this control for making an animated curved menu and this one for flip type transitions.
This control allows you to easily create a bar gauge, commonly seen on audio mixing boards, and seen within many apps from sound apps to battery power tracking apps.
You can totally customize the colors in this component, and you can customize the colors at different levels, so you can give everything a custom look.
In the screenshot below you can see gauges with a different look in action:
You can download the component from Github here.
Included is a sample application showing you exactly how to customize the component.
Looks like a great component to keep in mind in case you ever need a bar gauge.
