Metode Kelas
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).

Dinyatakan dalam: FBSDKAccessToken.h
refreshCurrentAccessToken:

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

ParameterKeterangan
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.

Dinyatakan dalam: FBSDKAccessToken.h
setCurrentAccessToken:

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

ParameterKeterangan
token

The access token to set.

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

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

Metode Instans
hasGranted:

Convenience getter to determine if a permission has been granted

ParameterKeterangan
permission

The permission to check.

- (BOOL) hasGranted:(NSString *)permission;
Dinyatakan dalam: FBSDKAccessToken.h
initWithTokenString:permissions:declinedPermissions:appID:userID:expirationDate:refreshDate:

Initializes a new instance.

ParameterKeterangan
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).

- (instancetype)
initWithTokenString: (NSString *)tokenString
permissions: (NSArray *)permissions
declinedPermissions: (NSArray *)declinedPermissions
appID: (NSString *)appID
userID: (NSString *)userID
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.

Dinyatakan dalam: FBSDKAccessToken.h
isEqualToAccessToken:

Compares the receiver to another FBSDKAccessToken

ParameterKeterangan
token

The other token

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

Konstan
FBSDKAccessTokenDidChangeNotification
FBSDK_EXTER N NSString *const FBSDKAccessTokenDidChangeNotification;
Discussion:

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

Dinyatakan dalam: 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).
