如何获取用户的电话号码？

Question

我刚刚开始使用Digits - Twitter API进行电话号码验证，但似乎我无法读取用户的电话号码，我不确定是否有这样的功能，但看了一会儿后我就知道了我可以通过电话验证成功后回拨来做到这一点，但没有解释！

AuthConfig.Builder authConfigBuilder = new AuthConfig.Builder()
                 .withAuthCallBack(callback)
                 .withPhoneNumber(phoneNumberOrCountryCodeFromMyActivity)

发现这个片段但又不确定在哪里实现它。

这是我的行动登录按钮与电话验证：

fileprivate func navigateToMainAppScreen() {
    performSegue(withIdentifier: "signedIn", sender: self)
}

@IBAction func tapped(_ sender: Any) {

    let configuration = DGTAuthenticationConfiguration(accountFields: .defaultOptionMask)

    configuration?.appearance = DGTAppearance()
    configuration?.appearance.backgroundColor = UIColor.white
    configuration?.appearance.accentColor = UIColor.red

    // Start the Digits authentication flow with the custom appearance.
    Digits.sharedInstance().authenticate(with: nil, configuration:configuration!) { (session, error) in
        if session != nil {
            // Navigate to the main app screen to select a theme.
            self.navigateToMainAppScreen()

        } else {
            print("Error")
        }
    }

}

Answer 1

所以我在Digits Documentations中挖掘了很多东西后得到了答案，这很简单，我不得不补充：

print(session.phoneNumber)
print(session.userID)

在didTap函数中，完整的代码将是：

@IBAction func tapped(_ sender: Any) {

    let configuration = DGTAuthenticationConfiguration(accountFields: .defaultOptionMask)

    configuration?.appearance = DGTAppearance()
    configuration?.appearance.backgroundColor = UIColor.white
    configuration?.appearance.accentColor = UIColor.red

    // Start the Digits authentication flow with the custom appearance.
    Digits.sharedInstance().authenticate(with: nil, configuration:configuration!) { (session, error) in
        if session != nil {

            //Print Data
            print(session?.phoneNumber)
            print(session?.userID)

            // Navigate to the main app screen to select a theme.
            self.navigateToMainAppScreen()

        } else {
            print("Error")
        }
    }

}
