Métodos de 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).

Declarado em: FBSDKAccessToken.h

setCurrentAccessToken:

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

Parâmetro	Descrição
`token`	The access token to set.

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

Discussion:

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

Métodos da instância

hasGranted:

Convenience getter to determine if a permission has been granted

Parâmetro	Descrição
`permission`	The permission to check.

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

Declarado em: FBSDKAccessToken.h

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

Initializes a new instance.

Parâmetro	Descrição
`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).

	`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.

Declarado em: FBSDKAccessToken.h

isEqualToAccessToken:

Compares the receiver to another FBSDKAccessToken

Parâmetro	Descrição
`token`	The other token

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

Declarado em: FBSDKAccessToken.h

Constantes

FBSDKAccessTokenDidChangeNotification

FBSDK_EXTER N NSString *const FBSDKAccessTokenDidChangeNotification;

Discussion:

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

Declarado em: 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.
