Facebook Auth和Firebase - 如何在同一Facebook应用程序下添加4个应用程序？

Question

Let's say I have 4 apps, "Uber Clone" for iOS and Android and "Uber Driver Clone" for iOS and Android. I am using the same Firebase project for all 4 since they share the same database.

When it comes to Facebook Auth though, I can only add a single Facebook app to Firebase. And for every Facebook App I can only add a single iOS and a single Android app. Therefore how can I make this work?

Firebasers, any recommendation/solution in mind?

Answer 1

A single Facebook App is allowed to connect to multiple iOS apps and multiple Android apps. For iOS apps, you can specify multiple Bundle ID at Facebook App settings page.

Answer 2

Taken you're using Firebase for authentication, I presume you're using either Real Time Database or Cloud Firestore to store user data as well. In your user data model, you can add user types.

For example,

user_type : "driver"

Then query users like so:

DBreference.collection("users").whereField("user_type", isEqualTo: "driver").getDocuments() {(querySnapshot, error) in 

if error != nil { print(error.debugDescription) 
return 
} 

else if let users = querySnapshot.documents {

for user in users {
guard let userType = user.data()["user_type"] as? String else { return } 
print(userType) 
} 

} 

}

This way you don't have to create multiple Facebook apps. Just use the one you have and segment users and their priviliges accordingly. For example, upon login on both apps, do a check, whether the is user trying to log in as a driver or a passenger.

if currentUser.userType != "passenger" {
print("You can't log into the passanger app with your driver's account.")
}

Hope this helps.

Answer 3

Multiple apps on a single Facebook app

1. Go to your Facebook developer console
2. Go to your app's page
3. Go to the basic settings

4. Add all relevant bundle IDs
5. Here's the key: Add a different URL Scheme suffix for each app. This differentiates each iOS app under your single Facebook App.

6. In each of your apps info.plist add the suffix information (Make sure both the URL scheme is updated and the "FacebookURLSchemeSuffix" is added!)

7. Now each of your apps is under the same Facebook App, and thus can register under the same Firebase Realtime Database. Check this out for more info: Two iOS apps using the same Facebook app ID - is it possible?

At this point in time, it does not seem possible to have multiple FB apps under a single Firebase Realtime Database.
