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

Had the same problem. Solved it having removed the square brackets in the app id
...rfaceOrientationPortraitUpsideDown</string>
<string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>CFBundleURLTypes</key>

<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb123456789012345</string>
</array>
</dict>

</plist>
