How to save image to PhotosAlbum

I want to save a image to PhotosAlbum , but I can’t write Obj-c ,

in the obj-c this is only one-line

UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

how can I write the plugin, :cry:

I test that TecturePlugin in my unity iphone adv, but it failed, how should I do.

Stinkbot’s Enhancement Pack will do this for you.

It’s very good , but I only need a function to save,

Is Stinkbot compatible with Unity 3.1? The Stinkbot website appears to have had no activity since 2008. Would want to know if there are issues before purchasing.
