Metodi di classe

currentAccessToken

Returns the "global" access token that represents the currently logged in user.

+ (FBSDKAccessToken *) currentAccessToken;

Discussion:

The currentAccessToken is a convenient representation of the token of the current user and is used by other SDK components (like FBSDKLoginManager).

Tipo dichiarato in: FBSDKAccessToken.h

refreshCurrentAccessToken:

Refresh the current access token's permission state and extend the token's expiration date, if possible.

Parametro	Descrizione
`completionHandler`	An optional callback handler that can surface any errors related to permission refreshing.

+ (void) refreshCurrentAccessToken:(FBSDKGraphRequestHandler)completionHandler;

Discussion:

On a successful refresh, the currentAccessToken will be updated so you typically only need to observe the FBSDKAccessTokenDidChangeNotification notification. If a token is already expired, it cannot be refreshed.

Tipo dichiarato in: FBSDKAccessToken.h

setCurrentAccessToken:

Sets the "global" access token that represents the currently logged in user.

Parametro	Descrizione
`token`	The access token to set.

+ (void) setCurrentAccessToken:(FBSDKAccessToken *)token;

Discussion:

This will broadcast a notification and save the token to the app keychain.

Metodi di istanza

hasGranted:

Convenience getter to determine if a permission has been granted

Parametro	Descrizione
`permission`	The permission to check.

- (BOOL) hasGranted:(NSString *)permission;

Tipo dichiarato in: FBSDKAccessToken.h

initWithTokenString:permissions:declinedPermissions:appID:userID:expirationDate:refreshDate:

Initializes a new instance.

Parametro	Descrizione
`tokenString`	The opaque token string.
`permissions`	The granted permissions. Note this is converted to NSSet and is only an NSArray for the convenience of literal syntax.
`declinedPermissions`	The declined permissions. Note this is converted to NSSet and is only an NSArray for the convenience of literal syntax.
`appID`	The app ID.
`userID`	The user ID.
`expirationDate`	The optional expiration date (defaults to distantFuture).
`refreshDate`	The optional date the token was last refreshed (defaults to today).

`expirationDate:`	`(NSDate *)expirationDate`
`refreshDate:`	`(NSDate *)refreshDate`
	`NS_DESIGNATED_INITIALIZER;`

Discussion:

This initializer should only be used for advanced apps that manage tokens explicitly. Typical login flows only need to use FBSDKLoginManager along with +currentAccessToken.

isEqualToAccessToken:

Compares the receiver to another FBSDKAccessToken

Parametro	Descrizione
`token`	The other token

- (BOOL) isEqualToAccessToken:(FBSDKAccessToken *)token;

Costanti

FBSDKAccessTokenDidChangeNotification

FBSDK_EXTER N NSString *const FBSDKAccessTokenDidChangeNotification;

Discussion:

The userInfo dictionary of the notification will contain keys FBSDKAccessTokenChangeOldKey and FBSDKAccessTokenChangeNewKey.

Tipo dichiarato in: FBSDKAccessToken.h

FBSDKAccessTokenDidChangeUserID

FBSDK_EXTER N NSString *const FBSDKAccessTokenDidChangeUserID;

Discussion:

Token refreshes can occur automatically with the SDK which do not change the user. If you're only interested in user changes (such as logging out), you should check for the existence of this key. The value is a NSNumber with a boolValue. On a fresh start of the app where the SDK reads in the cached value of an access token, this key will also exist since the access token is moving from a null state (no user) to a non-null state (user).
