Create Parse user without internet connection

I'm using the following code for the creation of a user,

[user signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

but since I have no interest connection I get an error that there is no internet connection, and [PFUser currentUser] stays nil.

I thought that with the local data store Parse would create the user but I am obviously wrong, is there a way to create a user without internet connection?
