plugin com.apple.share.Facebook.post invalidated

Question

In my app I'm using the following code that allows to share an image with a text:

- (IBAction)sharePressed:(id)sender {
    UIImage *postingImage = [UIImage imageWithContentsOfFile:self.filepath];
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[@"Lorem ipsum", postingImage] applicationActivities:nil;
    [self presentViewController:activityViewController animated:YES completion:nil];
}

Posting the image to Facebook works fine and it appears on my FB wall, however in my console I get the following message:

plugin com.apple.share.Facebook.post invalidated

I've tested it on a couple of devices, as far as I could see it only happens on my iPhone 6 with iOS 8.1 installed.

Anyone knows what that message means and how to prevent it from showing?

Answer 1

Here is the correct answer ios plugin com.apple.share.Facebook.post do not show provided text. It's a bummer.

I'm afraid to tell you, you cannot post text to Facebook programatically. It's a new Facebook prohibition that forbids "pre-filled" Facebook sharing. That is why newer versions of iOS do not show your text, even tough it's correctly provided (and works on Twitter and in other sharing options).
