Question

What I have and what’re problems occurred:

1. I’ve one Facebook account with game application (every day people’s playing)
2. I’ve one more Facebook account with test application, that created recently with default settings.
3. I’ve native Facebook application on my iPod
4. I’m developing iOS application which uses Facebook iOS SDK.

Invalid flow:

If I use App ID/API Key from first application, I open my application and trying to login. Facebook SDK opens native FB application and show me that screen

I press OK and go back to my iOS with such error and without access token:

(NSError *) $0 = 0x001710f0 Error Domain=com.facebook.sdk Code=2 "The operation couldn’t be completed. (com.facebook.sdk error 2.)" UserInfo=0x16d4b0 {com.facebook.sdk:ErrorLoginFailedOriginalErrorCode=210}

Valid flow:

If I use App ID/API Key from second (test) application, I open my application and trying to login. Facebook SDK opens native FB application and show me that screen

I press OK and go back to my iOS with valid access token.

Settings of applications are the same, I didn’t see any differences. This problem occurred if I have native Facebook application. If I haven’t it, Facebook SDK opens browser and authorization will be successful with first and second App ID.

If someone had such problem, please help. Thanks a lot.

I solved the issue.

Actually after changing here and there I found my bundle id was not matching. I have kept the bundle id same in the following 3 places and it worked:

1. The bundle identifier of your project.
2. In your FB a/c the filed named “iOS Bundle ID:” under head Native iOS App.
3. The notification string value in your AppDelegate.m

   NSString *const FBSessionStateChangedNotification = @"yourbundleid:FBSessionStateChangedNotification";
