PFUser-Digits

A way to authenticate Parse Users using the Twitter Digits API

Make sure you setup your project with Digits and with Parse

Installation

Add the files "PFUser+Digits.{h,m}" to your project.

Note: This cannot be a cocoapod at the moment since Digits is a static binary so it cannot be added as a dependency. If anyone knows a workaround please let me know.

Make sure to setup the twitter oauth when starting your parse server:

var api = new ParseServer({
    ...
    oauth: {
        twitter: {
            consumer_key: "CONSUMERKEY",
            consumer_secret: "CONSUMERSECRET"
        },
        facebook: {
            appIds: "FACEBOOK"
        }
    }
});

#Parse.com version If you are still using the Parse.com hosted server, you should use the old version of this repo, which required you to add extra cloud-code as well, it is still available under this branch: parse-hosted

#Login with Digits

When you setup parse, you also need to call:

[PFUser enableDigitsLogin];

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 theese digits properties are available for the current user:

-(nullable NSString *)digitsId;
-(nullable NSString *)digitsEmail;
-(nullable NSString *)digitsPhone;

You may wish to copy the digitsEmail to the stored email property on PFUser.

Note: to get the email you must specify DGTAccountFieldsEmail in the configuration as below for instance)

#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];
