If youâve used the PFUser object before, this should look very familiar, except that you're making a call to PFFacebookUtils. Notice that we create a permissions array. This indicates what data we want to access once the user is logged in. The full list can be found on the Facebook developer website.
pro-1. 1  a prefix indicating favor for some party, system, idea, etc., without identity with the group (pro-British; pro-Communist; proslavery), having anti- as its opposite.
Pro-form is a word or phrase that can take the place of another word (or word group) in a sentence. The process of substituting pro-forms for other words is called proformation. In English, the most common pro-forms are pronouns, but other words (such as here, there, so, not, and do) can also function as pro-forms. (See Examples and Observations, below.) The pro-form is the referring word in a sentence; the word or word group that's referred to is the antecedent.
