facebook ios sso getting "safari cannot open page" error

Question

I've been developing an app for android and iphone, and been able to implement sso on android but when I try to implement it on iOS I get the above mentioned error :

"Safari cannot open the page because the address is invalid"

The error is shown after I click "okay" to give the permissions to my personal information on facebook to the app

the link in question is : m.facebook.com/dialog/oauth?refid=0

here is my info.plist file

<plist version="1.0">

Answer 1

Had the same problem. Solved it having removed the square brackets in the app id

               ...rfaceOrientationPortraitUpsideDown</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb123456789012345</string>
        </array>
    </dict>
</array>
</dict>
</plist>

dont use any square bracets around the app id
