Facebook offer and options for adding social plugins to your app. Here is a link to their directions for a "page plugin" that also had tabs to other plugin options:
After you paste in the URL of the Facebook page you want to add to your app, you will also set the size of the window in your app when the feed will be viewed. We recommend a width of 320 and a height of 400, but you can vary the dimensions to fit your need.
With Facebook, when you tap "Get Code", you will see a window with two blocks of HTML code:
You will use the platform's HTML action to add a Facebook Feed and you will need to add both blocks of HTML from facebook into the "HTML code" box of the HTML Action.
Simply paste in the first block of HTML and then paste the second block below the first in the same HTML code box.
Be sure and try other Facebook embeds if they look like they will be a better fit for the use case.
