loadFriends

public void loadFriends(GKLocalPlayer.Block_loadFriends completionHandler)

* loadFriends: * * Discussion: * Calling this method will asynchronously load the player Game Center's * friend list scoped to the calling application. * Calls handler when finished. * * When -loadFriendsAuthorizationStatus == GKFriendsAuthorizationStatusNotDetermined or * GKFriendsAuthorizationStatusRemoved, calling this method will trigger a * prompt to request friend list authorization from the user. * * When -loadFriendsAuthorizationStatus == GKFriendsAuthorizationStatusAuthorized, * This method will return an array of GKPlayers which have agreed to share their * friend list with the calling application based on the same bundleID. * * The NSGKFriendListUsageDescription key must be specified in your * Info.plist; otherwise, GKErrorFriendListUsageDescriptionMissing will be returned, * as your app will be assumed not to support friend list.

* Possible reasons for error: * - Communication error with server. * - AuthorizationStatus != GKFriendsAuthorizationStatusAuthorized * - NSGKFriendListUsageDescription missing from your Info.plist * - User is not online * - Unauthenticated player

loadFriendsAuthorizationStatus

public void loadFriendsAuthorizationStatus(GKLocalPlayer.Block_loadFriendsAuthorizationStatus completionHandler)

loadFriendsAuthorizationStatus:

Discussion: Calling this will asynchronously load the current friend list authorization status of calling application. There may be an server call involve so there could be some slight delay in getting the authorization status via handler block. Calls handler when finished. Error will be nil on success.

Possible reasons for error: - Communication error with server. - NSGKFriendListUsageDescription missing from your Info.plist - User is not online - Unauthenticated player

loadFriendsWithIdentifiers:completionHandler:

Discussion: Calling this method will asynchronously return a list of GKPlayers to the provided scoped identifiers (gamePlayerID or teamPlayerID) that you can use to interact with GameKit framework. Calls handler when finished.

When -loadFriendsAuthorizationStatus == GKFriendsAuthorizationStatusNotDetermined or GKFriendsAuthorizationStatusRemoved, calling this method will trigger a prompt to request friend list authorization from the user.

This method accepts gamePlayerID or teamPlayerID, and if the identifier is valid, we will return a GKPlayer object correspond to that identifier.

No GKPlayer object will be returned for invalid identifiers. If all supplied identifiers are invalid, and empty array will be returned.

If a player's friend revoke the friend list authorization for your application, we will no longer return the GKPlayer object and you should delete the data you've collected for the player with gamePlayerID or teamPlayerID on your end.

Possible reasons for error: - Communication error with server. - AuthorizationStatus != GKFriendsAuthorizationStatusAuthorized - NSGKFriendListUsageDescription missing from your Info.plist - Unauthenticated player - User is not online
