在iOS应用程序中将FirebaseUI直接登录到手机

我正在尝试在iOS应用程序中实现

FirebaseUI

，以进行

电话身份验证

。但是打开的UI显示“使用邮件登录”选项

我需要它直接进入手机登录页面-

如何在FirebaseUI中实现这一点。此外，在出现此视图之前，我如何填写电话号码字段？

您应该在代码中的某个位置（可能在视图控制器中）创建一个类型为

FUIAuth

的对象

// Perhaps you made it by doing this.
let authUI = FUIAuth.defaultAuthUI()

// You should also have a `FUIPhoneAuth` object somewhere.
let phoneProvider = FUIPhoneAuth(authUI: authUI)

// This will suppress the "Sign in with mail button"
authUI.isSignInWithEmailHidden = true

// This will bypass that welcome screen altogether 
// (because there is only a single element in the array).
authUI.providers = [phoneProvider]

如果你已经知道电话号码，你可以这样做。假设

self

是呈现firebase ui的视图控制器

let phoneNumber = "+12345558888"
phoneProvider.signIn(withPresenting: self, phoneNumber: phoneNumber)

---

这将直接打开电话验证屏幕

if let authUI = FUIAuth.defaultAuthUI() {

        let phoneProvider = FUIPhoneAuth(authUI: authUI)

        authUI.delegate = self

        authUI.providers = [phoneProvider]

        authUI.signIn(withProviderUI: phoneProvider, presenting: self, defaultValue: nil)
}

---

应该从控制器调用。

让我们假设您有一个带有按钮的视图控制器来启动手机验证。这是应包含在按钮（obj-c）中的代码

// Perhaps you made it by doing this.
let authUI = FUIAuth.defaultAuthUI()

// You should also have a `FUIPhoneAuth` object somewhere.
let phoneProvider = FUIPhoneAuth(authUI: authUI)

// This will suppress the "Sign in with mail button"
authUI.isSignInWithEmailHidden = true

// This will bypass that welcome screen altogether 
// (because there is only a single element in the array).
authUI.providers = [phoneProvider]

下面的数组可能包含验证用户的不同选项（使用Facebook、google、电子邮件…），在这种情况下，我们只需要phone方法，但可能数组中还包含电子邮件方法

NSArray<id<FUIAuthProvider>> * providers = @[ [[FUIEmailAuth alloc] init],[[FUIPhoneAuth alloc]initWithAuthUI:[FUIAuth defaultAuthUI]]];
authUI.providers = providers;

这是显示多个选项的默认方式

//    UINavigationController *authViewController = [authUI authViewController];
//    [self presentViewController:authViewController animated:YES completion:nil];
}

//    UINavigationController *authViewController = [authUI authViewController];
//    [self presentViewController:authViewController animated:YES completion:nil];
}
