"pull up" animation on drag

Question

I am trying to achieve an effect where a user drags on a tab and it reveals a toolbar underneath what you dragged. It is similar to the pandora app linked. On the Pandora app, next to the thumbs up, there is a tab. When you drag it up, it shows a volume bar underneath. I tried detecting gestures on the "tab" to animate it moving upwards, but failed miserably. Is there a better way of achieving the drag-to-reveal effect?

There's no better way to create a "drag-to-reveal" effect; UIPanGestureRecognizer is your best option.

See this SO answer for guidance on moving UIViews with a UIPanGestureRecognizer.
