I\'m trying to implement the new oAuth2 facebook SDK into my app but can\'t for the life of me understand how I\'m supposed to get back to my app once logged in/authenticate
Arg, you better open .plist as code source, you should see :
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb38*******</string>
</array>
</dict>
</array>
I had this same problem. Just to clarify some of the other answers, here's how I fixed the issue for my iPhone app in Xcode 4.2:
.plist file
"URL types"
"Item 0"
"URL Schemes"
"Item 0"
"fb21593853845xxxx"
You must write your AppID to your .plist
