登录时打开Facebook应用程序，Uber怎么做？

Question

How does Uber open Facebook app, when user is login in with facebook?

In my case, I have a project with iOS8 deployment target, 4.16 FBSDK and app always opens SafariView, which is done by design, I guess ?

Does Uber use an old SKD or I am simply using FBSDK wrong? This is how I login. I even set to use native app.

fbLoginManager.loginBehavior = .Native 
fbLoginManager.logInWithReadPermissions(["email", "public_profile", "user_birthday"], fromViewController: vc) { (result, error) in...

And I've modified plist according to Facebook

Answer 1

Facebook previously open the Facebook native app if it was installed in your device.

But From iOS9, This is now the default behaviour for Facebook SSO.

According to them opening Facebook in Safari is a better UI experience for users. By modifying keys in .plist will not help to open native app.

For apps on iOS 8 and below, Facebook Login checks to see if the Facebook app is installed on the device. If the app is installed, the SDK switches to the Facebook app via a fast-app-switch to display the Login experience.

Check in Which iOS version, you are checking Uber app. But as far as it concern, you will get logged in properly using browser too.

You can use old sdk to achieve this functionality.

If you are using Facebook SDK v4.6, It will use Safari view controller by default.

Try using a version of the SDK v4.5 or older and all the settings in plist according to it. For more information on this regarding plist and code for SDK v4.5 you can checkout this link : https://developers.facebook.com/docs/ios/ios9

I had this issue, but it was resolved when I turned my Facebook App (on the Facebook dev site) live.

When it was in dev mode, it did the SSO in Safari, and when released it did it through the native app
