如何獲取用戶的電話號碼?

[英]How to get user's phone number?

我剛剛開始使用Digits - Twitter API進行電話號碼驗證,但似乎我無法讀取用戶的電話號碼,我不確定是否有這樣的功能,但看了一會兒后我就知道了我可以通過電話驗證成功后回撥來做到這一點,但沒有解釋!

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

發現這個片段但又不確定在哪里實現它。

這是我的行動登錄按鈕與電話驗證:

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")
        }
    }

}

所以我在Digits Documentations中挖掘了很多東西后得到了答案,這很簡單,我不得不補充:

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

在didTap函數中,完整的代碼將是:

@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")
        }
    }

}
