iOS share to facebook/twitter button images

Question

I want to enable users in my app to share to facebook and twitter. However, I don't want to simply use text buttons such as "Share to facebook" but rather use images with each companies respective logos/icons. My problem is I can't find any "official" share images for iOS on either companies website. The only link I found for twitter was inactive. Where can I find these official share to facebook/twitter images which are approved for use in third party applications?
