FBFrictionlessRecipientCache
This class is no longer available in the most recent version of the SDK.

Maintains a cache of friends that can recieve application requests from the user in using the frictionless feature of the requests web dialog.

This class follows the FBCacheDescriptor pattern used elsewhere in the SDK, and applications may call one of the prefetchAndCacheForSession methods to fetch a friend list prior to the point where a dialog is presented. The cache is also updated with each presentation of the request dialog using the cache instance.

Checks to see if a given user or FBID for a user is known to be enabled for frictionless requestests

ParameterDescription
user

An NSString, NSNumber of FBGraphUser representing a user to check

prefetchAndCacheForSession:

Issues a request and fills the cache with a list of users to use for frictionless requests

ParameterDescription
session

The session to use for the request; nil indicates that the Active Session should be used

- (void) prefetchAndCacheForSession:(FBSession *)session;
prefetchAndCacheForSession:completionHandler:

Issues a request and fills the cache with a list of users to use for frictionless requests

ParameterDescription
