Facebook iOS SDK 4.X - How to send "App Requests"

Question

Facebook 3.X

 [FBWebDialogs presentRequestsDialogModallyWithSession:nil
                                                      message:[NSString stringWithFormat:@"Discover celebrities in real life."]
                                                        title:nil
                                                   parameters:nil
                                                      handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                                          if (error) {
                                                              // Case A: Error launching the dialog or sending request.
                                                              NSLog(@"Error sending request.");
                                                          } else {
                                                              if (result == FBWebDialogResultDialogNotCompleted) {
                                                                  // Case B: User clicked the "x" icon
                                                                  NSLog(@"User canceled request.");
                                                              } else {
                                                                  NSLog(@"Request Sent.");
                                                              }
                                                          }}];

Facebook 4.X documentation says that FBWebDialogs "is replaced by strongly typed dialogs. See FBSDKGameRequestDialog, FBSDKAppGroupAddDialog, FBSDKAppGroupJoinDialog."

I'm looking at initializing FBSDKAppGroupJoinDialog but how is this done, is there an example?

Answer 1

FBSDKAppGroupJoinDialog *appGroupJoinDialog = [[FBSDKAppGroupJoinDialog alloc] init];
appGroupJoinDialog.delegate = self;
appGroupJoinDialog.groupID = groupID;  // <-- this is the group ID to join
[appGroupJoinDialog show];
