FBSDKLog: Cannot use the Facebook app or Safari to

Question

I want to have the Facebook app native dialog login (https://developers.facebook.com/docs/technical-guides/iossdk/login/#fbnative).

In the console, I get the following message when clicking on the FBLoginView:

FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb**** is not registered as a URL Scheme

Yet I did exactly as here: Failing to open active session after updating Facebook SDK to 3.5

Answer 1

In my app, the error was caused because the case of the property keys was incorrect.

They should be:

URL types (lowercase T)

URL Schemes (uppercase S)

Answer 2

Found the solution for us:

We had two URL schemes defined. One for our app "ourapp://" and one for facebook "fb123456789".

As it turns out, the facebook URL has to be number one.

Answer 3

I fixed this issue by removing the space i had between fb and my app ID in the info.plist

Answer 4

In myapp-Info.plist, I renamed URL Schemes key to CFBundleURLSchemes:

Before:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>URL Schemes</key>
        <array>
            <string>fb***</string>
        </array>
    </dict>
</array>

After:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb***</string>
        </array>
    </dict>
</array>

The difference is not visible in XCode because CFBundleURLSchemes is aliased with URL Schemes.

As a consequence, you have to edit myapp-Info.plist manually.
