I was wondering how to make my app when it opens up have a signin screen? I want it to where you can signin with either Google +, Facebook & Twitter, & if they don't have a account there will be a signup button or if they forgot their password a forgot password button. The other thing I'd like to learn how to do is have a little popup menu that will have a refresh button and a exit the app button. If this is confusing at all please feel free to let me know.
