我实现了 Twitter 分享按钮,但是没有像这张图片那样更改 Twitter 帐户的列。如果我从该帐户注销,我将无法授权(登录)另一个帐户。要授权的视图永远不会出现。

它有 Account 和 Location 列

我的应用没有 2 列(“帐户”和“位置”)。所以除非我一开始授权,否则我不能更改帐户。我怎么解决这个问题?

(如果可能的话,最好在授权和推文一次后从所有帐户注销时能够授权帐户。但我不知道该怎么做......)

        let shareImage = UIImage(named:"Twitter_shareImage")
        let tweetDescription:String = "text"
        TWTRTwitter.sharedInstance().sessionStore.saveSessionWithAuthToken(authToken, authTokenSecret: authTokenSecret, completion: { (session, error) -> Void in

        if (TWTRTwitter.sharedInstance().sessionStore.hasLoggedInUsers()) {

            if let session = TWTRTwitter.sharedInstance().sessionStore.session() {

                let composer = TWTRComposer()
                composer.setText("text")
                composer.setImage(shareImage)
                composer.show(from: self.parentViewController()!, completion: nil)

                print(session.userID)

            } else {

                TWTRTwitter.sharedInstance().logIn {
                    (session, error) -> Void in
                    if (session != nil) {
//                        println("signed in as \(session.userName)");
                    } else {
//                        println("error: \(error.localizedDescription)");
                    }
                }

                print("no account")
            }

        } else {
            // Log in, and then check again
            TWTRTwitter.sharedInstance().logIn { session, error in
                if session != nil { // Log in succeeded
                    let composer = TWTRComposer()
                    composer.setText("text")
                    composer.setImage(shareImage)
                    composer.show(from: self.parentViewController()!, completion: nil)
                } else {
                    let alert = UIAlertController(title: "No Twitter Accounts Available", message: "You must log in before presenting a composer.", preferredStyle: .alert)
                    self.parentViewController()?.present(alert, animated: false, completion: nil)
                }
            }
        }
