Facebook App Invites FBSDKAppInviteDialog not appearing for test users on iOS simulator

Question

I have implemented Facebook's new 4.0 SDK App Invites Dialog for iOS as per: https://developers.facebook.com/docs/app-invites/ios

I am testing it out in the simulator.

When I login with my real Facebook account the App Invite dialog appears and I see all of my friends. To test the notifications though I want to use facebook test users as this is what the guide recommends:

We have internal logic that determines whether a push notification is sent to the client. If we detect that the person has installed the app, we may not trigger a push notification. The best way to test push notifications is to use test users .

However, when I login as a test user for my app and try to bring up the dialog it fails with the following error:

Error in invite Error Domain=com.facebook.sdk.core Code=2 "The operation couldn’t be completed. (com.facebook.sdk.core error 2.)" UserInfo=0x7f989d8cbe00 {com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Invalid method_results., com.facebook.sdk:FBSDKErrorArgumentNameKey=method_results}

If I try with the same test user on the actual phone it works fine. It seems this issue only occurs on the simulator.

Updated to add the code I'm using:

    var inviteDialog : FBSDKAppInviteDialog = FBSDKAppInviteDialog()
    if (inviteDialog.canShow()) {
        let appLinkUrl : NSURL = NSURL(string: "https://fb.me/1616988365211522")!
        let previewImageUrl : NSURL = NSURL(string: "http://upload.wikimedia.org/wikipedia/commons/4/4f/Polistes_May_2013-2.jpg")!

        var inviteContent : FBSDKAppInviteContent = FBSDKAppInviteContent()
        inviteContent.previewImageURL = previewImageUrl
        inviteContent.appLinkURL = appLinkUrl
        inviteDialog.content = inviteContent

        inviteDialog.delegate = self
        inviteDialog.show()
    }

elsewhere....

func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
    // nothing to do here
    println("Completed App Invite with results: \(results)")
}

func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
    // don't know enough about the errors to let the user know
    println("Error in App Invite: \(error)")
}

Note, this is a test version of my app. The Apple App Store id is not my app (obviously) but since my app is not yet on the store I needed to add something for testing.

Answer 1

i have encountered the same issue ,in my case when i was testing app invite , it was working fine for all user except for one , and the error was: Printing description of error:

Error Domain=com.facebook.sdk.core Code=2 "The operation couldn’t be completed. (com.facebook.sdk.core error 2.)" UserInfo=...     {com.facebook.sdk:FBSDKErrorArgumentNameKey=method_results,  com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Invalid method_results.}

and this error was occurring for the user whose account i created on Facebook but didn't confirm that account from email link ,after confirming the account this error didn't appeared and i was able to send invite from that particular user.

Hope this will help :)

1. You should upgrade Facebook SDK version
2. Look again at your app's page in Facebook Developer dashboard and check if every required field has a valid value.
3. Test on real device and look if there is any difference in Facebook SDK response.
