Xamarin 错误 IOS Firebase AuthDataResult 不包含 ProfileChangeRequest()

Question

当我尝试更改用户名时收到一条错误消息，提示 AuthDataResult 不包含 ProfileChangeRequest()。我必须在线研究并阅读 firebase 文档，但没有运气。

public static async Task Register(UIViewController thisView,
                                       string inpName,
                                      string inpEmail,
                                      string inpPassword)
    {
        bool done = false;
        AppDataClass.auth.CreateUser(inpEmail, inpPassword, (user, error) =>
        {
            if (error != null)
            {
                AlertShow.Alert(thisView, "Error",
                                "This went wrong: " + error.UserInfo.Description);
                return;
            }

            UserProfileChangeRequest changeReq = user.ProfileChangeRequest;
            changeReq.DisplayName = inpName;

            changeReq.CommitChanges((profileError) =>
            {
                if (profileError != null)
                {
                    AlertShow.Alert(thisView, "Error",
                                    "Profile Error: " + profileError);
                    return;
                }

                done = true;
            });

        });

        while (!done)
        {
            await Task.Delay(50);
        }
    }

如果您阅读有关方法的文档 -signInWithEmail:password:completion:, the call back it retures is a FIRAuthDataResultCallback , the first parameter here is FIRAuthDataResult。

所以用户应该是：

user.user.ProfileChangeRequest

说清楚：

public static async Task Register(UIViewController thisView,
                               string inpName,
                              string inpEmail,
                              string inpPassword)
{
    bool done = false;
    AppDataClass.auth.CreateUser(inpEmail, inpPassword, (authDataResult, error) =>
    {
        if (error != null)
        {
            AlertShow.Alert(thisView, "Error",
                            "This went wrong: " + error.UserInfo.Description);
            return;
        }

        UserProfileChangeRequest changeReq = authDataResult.user.ProfileChangeRequest;
        changeReq.DisplayName = inpName;

    });

    while (!done)
    {
        await Task.Delay(50);
    }
}
