Failing to open active session after updating Facebook SDK to 3.5

Question

After updating the Facebook sdk to 3.5, when trying to perform openActiveSessionWithReadPermissions the operation fails. Here is the snippet for opening the session and handling the callback:

[FBSession openActiveSessionWithReadPermissions:@[@"email", @"user_hometown", @"user_location", @"user_birthday"]
                                   allowLoginUI:YES
                              completionHandler:
 ^(FBSession *session,
   FBSessionState state, NSError *error) {
     switch (state) {
         case FBSessionStateCreatedTokenLoaded:
         case FBSessionStateOpenTokenExtended:
         case FBSessionStateOpen:
         {
             completion(TRUE);
             break;
         }
         case FBSessionStateClosed:
         case FBSessionStateClosedLoginFailed:
             completion(FALSE);
             [FBSession.activeSession closeAndClearTokenInformation];
             break;
         default:
             break;
     }
 }];

I end up in the FBSessionStateClosedLoginFailed case and I get a FBSKLog as follows:

FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb123456789012345 is not registered as a URL Scheme

Answer 1

I Had the same problem (Facebook SDK 3.5.1)

My URL scheme for Facebook was on Item 1 in the Info.plist URL schemes. Problem fixed by moving it to Item 0.

Answer 2

I had the same problem. The code above fixed this issue. U have to edit your .plist file with text editor. But in Xcode u will not see any changes. Instead of URL Types - CFBundleURLTypes and instead of URL Schemes should be CFBundleURLSchemes.

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb48524**********</string>
        </array>
    </dict>
</array>
