Take the 2-minute tour ×  I have created a drop down banner
system, like GameKits (When you get an achievement for example).
I can easily display the banner in one view with the code below.
However, all my server code is stored in a singleton class, and
would like to notify the user when something happens in there
(regardless what view controller they are in). How would I go
about doing this?  [self displayBannerWithTitle: @"title here"];
Thanks in advance  share|improve this question add comment  1

Controllers In your case it's passing data to and from (The
