I'm trying to update Parse user info in my app, but I don't know how to update it.
In my view controller I have UsernameTxtField, NicknameTxtField, PasswordTxtField and UpdateButton.
I want the user to set information inside the text field, then press the Update button to update them on Parse.com.
How should I do a query?
var query = PFQuery(className: "_User")
How can I do that? Can someone give me a code similar to this?
