iOS 8 Facebook share link, image and text

I want to share a content with an image, an url of my app on store and a caption of image. I tried to using SLComposeViewController, but it not working on iOS 8. I tried to using FaceBook share link, but it need an image url. How can I share image + url + text without any server to store image? Thanks all!

Due to FB policy is not possible to autofill the text of a share sheet using SLComposeViewController or UIActivityViewController. It seems to be still possible to share a link.
The behavior seems to be different if you have the official FB app installed:

• If it is installed you can't add text
• If not you can The only solution seems to implement the official library, is really a pity!!
