How to change the Facebook account on my iPhone?

My best friend wanted to share a picture to her Facebook from my phone so she put in her information and shared it and now every time I want to do it it goes to her profile. Like its confusing me because I have the Facebook app and that's logged on to my profile but when I want to put a picture or video up it goes onto hers? Does anyone know how to change that? I would help me a lot!

Go on the app, and slide the white news feed to the right side, so that you see the left toolbar that says "profile" and "news feed" and all that stuff (opposite of the list of your online friends). Scroll all the way to the bottom and click "log out".It will then take you to the login screen where you can sign in with a new account. Hope I could help

I would try logging out, it's top left hand side you will see 3 lines, click that and go all the way to bottom and click log out then log into your account again or if you have the updated viersion on the bottom of your screen you will see "more" click that then scroll down to bottom where it says "log out" and log in again with your account

hope this helps
