Facebook SDK 4.5 IOS 9

Question

I got an issue with the new FBSDK. Whenever I try to call the login method logInWithReadPermissions, I get this error message:

ERROR : "canOpenUrl : failed for url "fbauth2://" error: "(null)"

I have my config .plist file following the ios9 tuto ( https://developers.facebook.com/docs/ios/ios9 ) on dev.facebook. So, I got the NSAppTransportSecurity dictionary and the LSApplicationQueriesSchemes array (with the string "fbauth2" on it)

Would you know how to resolve this error?

Answer 1

I have the same problem with Google+ Sign-in library, but i solved for Facebook updating at the last SDK version 4.6.0!

Remember to change your plist key LSApplicationQueriesSchemes after the update like this:

<key>LSApplicationQueriesSchemes</key>
<array>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
</array>

Answer 2

If you still continue to have problems, reset the simulator, this worked for me.

Answer 3

if you already have items on LSApplicationQueriesSchemes. let the Facebook items first.

This solved my problem.

Answer 4

Use like this in info.plist

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb123124123123</string>
            <string>fbauth2</string>
        </array>
    </dict>
</array>

After that you should remove your app from editor and launch again.

From Facebook FAQ at the bottom of the link: https://developers.facebook.com/docs/ios/ios9

This is an Xcode warning indicating the the canOpenURL: call returned false. As long as you have configured the LSApplicationQueriesSchemes entry in your plist as described above, you can ignore this warning
