How can I animate Three20 TTThumbsViewController images?

Question

Hi,

I would like to animate some of the thumbnail images in the Three20 TTThumbsViewController view. The animations will occur randomly, not because of user interaction.

TTThumbsViewController subclasses TTTableViewController and uses TTThumbsTableViewCells to layout whatever number of TTThumbViews are needed in that cell. TTThumbViews are sublcassed TTButtons, which inherits from UIControl.

I've got a subclassed TTThumbsDataSource and a subclassed TTThumbsViewController, and I can invoke a method something like:

[self.datasource wigglePhotoAtIndexPath:13];

How do I go about animating a specific TTThumbView? Note that I can get to the right TTThumbView, I just can't get any animation to work.

Thanks!
