PFUser-Digits

A way to authenticate Parse Users using the Twitter Digits API

To call make sure you setup Digits login and also setup your project with Parse

Drag the PFUser+Digits.m and PFUser+Digits.h (or PFUser+Digits.swift) into your XCode project. Add the user.js file to your cloud code folder and include in your main.js file

require('cloud/user.js');

or copy the contents to main.js

#Login with Digits

To use just call the function which will trigger the Digits sign-in flow and when succeded, will authenticate or create a new user on Parse.

You may call using blocks:

[PFUser loginWithDigitsInBackground:^(PFUser *user, NSError *error) {
    if(!error){
      // do something with user
    }
}];

Or Using Bolts:

[[PFUser loginWithDigitsInBackground] continueWithBlock: ^id (BFTask *task) {
    if(!task.error){
      PFUser *user = task.result;
      // do something with user
    }
}];

#Link Existing Account

You can also link an existing account (anonymous or not) with Digits. This works in the same way as linking with Facebook and allows you to later on log back in using the Digits sign-in

[[PFUser currentUser] linkWithDigitsInBackground]; //returns BFTask*

or

[[PFUser currentUser] linkWithDigitsInBackground:^(PFUser* user, NSError* error) {}]; //block callback

#Stored properties After login or link the user's phone number will be available in the phone property, and if the user has linked his email in his digits account (by specifying DGTAccountFieldsEmail in the configuration as below for instance) it will be available in the email property.

[[PFUser currentUser] objectForKey:@"phone"]; //access to phone number after login
[PFUser currentUser].email; //access to email if it was found

#Logout Even if you logout your Parse User the Digits session is maintained separately, so if you would like to logout of Digits together with Parse, make sure to do something like below when logging out:

[[PFUser logOutInBackground] continueWithSuccessBlock:^(BFTask* task) {
    [Digits sharedInstance] logout];
}];

#Customising

For all the previous examples you can pass an DGTAuthenticationConfiguration object. Use it to configure the appearance of the login screen or pass in the phone number to verify. For more information view the Official documentation For example:

DGTAppearance *appearance = [DGTAppearance new];
appearance.backgroundColor = [UIColor whiteColor];
appearance.accentColor = [UIColor defaultLightBlueColor];
appearance.logoImage = [UIImage imageNamed:@"app_icon"];

DGTAuthenticationConfiguration *configuration = [[DGTAuthenticationConfiguration alloc] initWithAccountFields:DGTAccountFieldsEmail];
configuration.appearance = appearance;
configuration.phoneNumber = [User currentUser].phone;
configuration.title = NSLocalizedString(@"phone_login_title", nil);
[PFUser loginWithDigitsInBackgroundWithConfiguration:configuration];

#Swift Although the original objc code should still be usable from swift I did a rough translation of the extension to PFUser+Digits.swift, contributions to it or improvements to the readme with swift examples are much appreciated!

#Improvements If you are using revokable sessions, make sure to disable revoking sessions when user changes password. This is due to the fact that currently the only workaround I found to returning a session token from CloudCode was to login the user - and for that you need to specify the password. So the solution for now is to change the user's password before every login. Would really like a better solution so if you have any ideas please let me know.
