Facebook Messenger not showing up with UIActivityViewController

问题

I am using UIActivityViewController in my app to provide options for users to share some text.

Apps like facebook, twitter, whatsapp once installed they automatically show up as options with UIActivityViewController, but not Facebook Messenger.

Any special set up I need to do with Messenger? I am using objective c.

According to: Can't share text to fb messenger using UIActivityViewController

In order to make Facebook Messenger appear you need to insert NSURL into UIActivityViewController activityItems

NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
NSArray *activityItems = @[url];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
