I’ve mentioned a few libraries for adding interesting animation effects to interface views such as AGGeometryKit-Pop which allows you to easily perform 3D transform effects for more dynamic interfaces.
Here’s an open source component from Wojtek Lukaszuk that allows you to add a neat wobbling effect to a view which is great for user interactions such as when sliding cells in a table view called WobbleView.
With WobbleView you can easily set the position of the wobbling effect, and also the behavior of the actual wobble so you can wobble only a specific area of a view.
This animation from the readme shows how the effect could be used with a table view:
You can find WobbleView on Github here.
A nice library you can use to make interfaces a little more dynamic.
