应用程式因Firebase电话验证而当机 [英] App crashes with Firebase Phone Auth

问题描述

我希望这个问题不会重复，因为我找不到类似的东西.

I hope that this question is not duplicate because I couldn't find any thing similar.

我有两个视图控制器:

NEWPhoneAuthViewController

NEWVerifyCodeViewController

NEWPhoneAuthViewController代码:

NEWPhoneAuthViewController Code:

        import UIKit
import Firebase

class NEWPhoneAuthViewController: UIViewController {

    @IBOutlet weak var phoneTxtField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func submitPressed(_ sender: Any) {

        let phoneNumber = phoneTxtField.text!

        PhoneAuthProvider.provider().verifyPhoneNumber(phoneNumber, uiDelegate: nil, completion: { (verificationID, error) in

            if let error = error {
                debugPrint(error.localizedDescription)
                return
            }

            guard let verificationID = verificationID else { return }
            print("Verification ID")
            print(verificationID)
            let verifyScene = NEWVerifyCodeViewController()
            verifyScene.verificationID = verificationID

            self.performSegue(withIdentifier: "toCodefromPhoneAuth", sender: nil)
            //self.navigationController?.pushViewController(verifyScene, animated: true)
        })

    }


}

和我的NEWVerifyCodeViewController代码是:

and my NEWVerifyCodeViewController code is:

    import UIKit
import Firebase

class NEWVerifyCodeViewController: UIViewController {

    @IBOutlet weak var codeTxtField: UITextField!

    var verificationID:String?

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func verifyPressed(_ sender: Any) {
        if let verificationCode = codeTxtField.text {
            let credential = PhoneAuthProvider.provider().credential(withVerificationID: verificationID!, verificationCode: verificationCode)
            Auth.auth().signIn(with: credential) { (user, error) in
                if let error = error {
                    debugPrint(error.localizedDescription)
                }else {
                    debugPrint("Verified successfully")

                    print("Navigating to SignUp")

                    //self.performSegue(withIdentifier: "toSignUpfromCode", sender: nil)

                    //let newSignUp = NEWSignUp()
                    //self.navigationController?.pushViewController(newSignUp, animated: true)

                    //self.performSegue(withIdentifier: "toSignUpFromPhone", sender: nil)
                    //Once you have verified your phone number kill the firebase session.
                    //try? Auth.auth().signOut()

                }
            }
        }
    }
}

现在问题是:当我在NEWVerifyCodeViewController中点击验证按钮时，

Now the problem is: when I tap on verify button in NEWVerifyCodeViewController the App crashes,

注意:

• 我打印了验证ID，但不为NULL.
• 我打印了用户收到的代码，它不是NULL.

因此，我不确定为什么会发生这种情况，并且在点击之后，我的控制台没有显示任何错误，除了以下内容:

So I'm not sure why that happens, and my console doesn't show any error after the tap except these:

推荐答案

所以我做了一个小调整，使我的项目正常工作.

So I made a small tweak that made my project work.

我在 NEWPhoneAuthViewController 中更改了此部分:

let verifyScene = NEWVerifyCodeViewController()
verifyScene.verificationID = verificationID

收件人:

首先创建一个名为: gVerificationID 的全局变量，并将其设置为:

first created a global variable called: gVerificationID and set it to:

gVerificationID = verificationID

就是这样，不确定那是否是最佳实践，也不确定为什么第一个代码不起作用，但这就是我的解决方法.

Thats it, not sure if thats the best practice and not sure why the first code didn't work but this is how I fixed it.
