In one of our app, we are supposed to give an option to share newly unlocked Achievement. Requirement also includes to post defined text if share box is empty.
The problem is, we are unable to find relevant delegate method when user clicks on POST/Send button.
Code for posting status is,
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:awardToBeShareOnFB];
content.contentTitle = @"Helloworld";
content.contentDescription = @"Helloworld";
[FBSDKShareDialog showFromViewController:[self parentViewController]
withContent:content
delegate:self];
It should post "Helloworld" as a status if posting box is empty.
