 HOW IT WORKS

 The UIActionSheet category works virtually the same as the UIAlertView.  Just check out the header for the initializer you need to use.  It's very straightforward.
 
+The UIBarButtonItem category adds a new initializer taking an RIButtonItem:
+
+    [[UIBarButtonItem alloc] initWithStyle:UIBarButtonItemStyleBordered
+                                      item:buttonItem];
