facebook 4.x documentation says fbwebdialogs "is replaced typed dialogs. see fbsdkgamerequestdialog, fbsdkappgroupadddialog, fbsdkappgroupjoindialog."

i'm looking @ initializing fbsdkappgroupjoindialog how done, there example?

fbsdkappgroupjoindialog *appgroupjoindialog = [[fbsdkappgroupjoindialog alloc] init]; appgroupjoindialog.delegate = self; appgroupjoindialog.groupid = groupid;  // <-- group id join [appgroupjoindialog show];
