save image to picture

Do you mean to save picture to a phone photo library? If so, you can use this function to save image:

UIImageWriteToSavedPhotosAlbum(UIImage *image, id completionTarget, SEL completionSelector, void *contextInfo);

You only need completionTarget, completionSelector and contextInfo if you want to be notified when the image is done saving, otherwise you can pass in nil.
