• Answer:

  Ok,I understand if you want to send app request to your friends than you should use FBSDKAppInviteContent. Here is the code: FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init]; content.appLinkURL = [NSURL URLWithString:@"Your_App_Id"]; content.previewImageURL = [NSURL URLWithString:@"Your_app_previewimage"]; [FBSDKAppInviteDialog showWithContent:content delegate:self]; Here for Your_App_Id please refer to this https://developers.facebook.com/quickstarts/?platform=app-links-host. And it's delegate methods: - (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results{ if (results) { } } - (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didFailWithError:(NSError *)error{ if (error) { NSString *message = error.userInfo[FBSDKErrorLocalizedDescriptionKey] ?: @"There was a problem sending the invite, please try again later."; NSString *title = error.userInfo[FBSDKErrorLocalizedTitleKey] ?: @"Oops!"; [[[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show]; } }
