How to get downloaded UIImage data from TTPhoto

I use TTPhotoViewController and TTPhoto to display images. I want to get UIImage data from displayed TTPhoto and I checked these protocols but I couldn't find any methods or properties for it.

Is there any way to get displayed UIImage data in TTPho开发者_StackOverflow中文版toViewController?

Thank you.

You just can download the data your self and then send to the three20 your local path to load the photos.
