我得到的连续运行的皮棉：
我得到：private var selfDestructableNotificationToken: NotificationTokenThatAutomaticallyRemovesObserver?
final class NotificationTokenThatAutomaticallyRemovesObserver: NSObject { // more info here: https://oleb.net/blog/2018/01/notificationcenter-removeobserver/
let token: Any
init(_ token: Any) { self.token = token }
deinit { NotificationCenter.default.removeObserver(token) }
}
...
if let currentFBToken = FBSDKAccessToken.current() { // if this is a Facebook user, not an email-based user
if FBSDKAccessToken.currentAccessTokenIsActive() { // and his token has not expired yet
let token = NotificationCenter.default.addObserver(forName: NSNotification.Name.FBSDKAccessTokenDidChange, object: nil, queue: OperationQueue.main) { notification in
if let userInfo = notification.userInfo, let refreshedToken = userInfo["FBSDKAccessToken"] as? FBSDKAccessToken {
self.fbAccessToken = refreshedToken.tokenString
} else {
self.fbAccessToken = currentFBToken.tokenString // falling back to using an old token (better than none)
}
}
self.selfDestructableNotificationToken = NotificationTokenThatAutomaticallyRemovesObserver(token)
FBSDKAccessToken.refreshCurrentAccessToken { _, _, error in
if let error = error {
print("failed to refresh Facebook token with error \(error.localizedDescription)")
self.fbAccessToken = currentFBToken.tokenString // falling back to an old token (better than none)
}
}
} else if FBSDKAccessToken.current().isExpired { // unlucky user. Probably returned to the app after > 2 months break
self.fbAccessToken = currentFBToken.tokenString // assigning expired token. Facebook will ask user to relogin as soon as we call Graph API with that expired token
}
}
