试试这个软件包https://github.com/Twotalltotems/react-native-otp-input，它在两个平台上都能工作得最好。

有一个插件React Native Phone Verification适用于iOS和Android（跨平台）与此您可以使用验证码选择器匹配您的要求.

我们过去常常使用单个隐藏输入字段来完成它，如@Chethan的回答中所述。现在，由于RN已经在Android平台上支持返回按钮的回调（自RN 0.58甚至更早）。这可以通过一组文本输入的正常布局来实现。但我们还需要考虑iOS上的文本输入建议或Android上的自动填充。实际上，我们已经开发了一个库来处理这个问题。这里是blog来介绍这个库以及如何使用它。源代码是here。

@kd12345：你可以在这里做：

onChangeText={(val) => {
  setFieldTouched(`code${index + 1}`, true, false);
  setFieldValue(`code${index + 1}`, val);
  console.log(typeof val);
  // LITTLE MODIFICATION HERE
  if(index < 3 && val !== '') {
    references.current[index + 1].current.focus();
    // DO WHATEVER
  }
          
}}

您可以只使用一个隐藏的TextInput元素，并附加一个onChangeText函数和填充在文本视图中输入的值（您可以使用四个不同的文本视图的设计需要它）。如果用户点击文本视图，请确保将文本输入集中在点击文本视图上

在这里，我已经创建了一个屏幕六个文本输入为OTP验证与重新发送OTP功能与计数器计时器的90秒。在Android和iOS上进行了全面测试。

我已经使用react-native-confirmation-code-field作为带下划线的文本输入。下面是完整的代码。

import React, { useState, useEffect } from 'react';
import { SafeAreaView, Text, View ,TouchableOpacity} from 'react-native';
import { CodeField, Cursor, useBlurOnFulfill, useClearByFocusCell } from 
'react-native-confirmation-code-field';
import { Button } from '../../../components';
import { styles } from './style';

interface VerifyCodeProps {
}
const CELL_COUNT = 6;
const RESEND_OTP_TIME_LIMIT = 90;

export const VerifyCode: React.FC<VerifyCodeProps> = () => {
let resendOtpTimerInterval: any;

const [resendButtonDisabledTime, setResendButtonDisabledTime] = useState(
    RESEND_OTP_TIME_LIMIT,
);

//to start resent otp option
const startResendOtpTimer = () => {
    if (resendOtpTimerInterval) {
        clearInterval(resendOtpTimerInterval);
    }
    resendOtpTimerInterval = setInterval(() => {
        if (resendButtonDisabledTime <= 0) {
            clearInterval(resendOtpTimerInterval);
        } else {
            setResendButtonDisabledTime(resendButtonDisabledTime - 1);
        }
    }, 1000);
};

//on click of resend button
const onResendOtpButtonPress = () => {
    //clear input field
    setValue('')
    setResendButtonDisabledTime(RESEND_OTP_TIME_LIMIT);
    startResendOtpTimer();

    // resend OTP Api call
    // todo
    console.log('todo: Resend OTP');
};

//declarations for input field
const [value, setValue] = useState('');
const ref = useBlurOnFulfill({ value, cellCount: CELL_COUNT });
const [props, getCellOnLayoutHandler] = useClearByFocusCell({
    value,
    setValue,
});

//start timer on screen on launch
useEffect(() => {
    startResendOtpTimer();
    return () => {
        if (resendOtpTimerInterval) {
            clearInterval(resendOtpTimerInterval);
        }
    };
}, [resendButtonDisabledTime]);

return (
    <SafeAreaView style={styles.root}>

            keyboardType="number-pad"
            textContentType="oneTimeCode"
            renderCell={({ index, symbol, isFocused }) => (
                <View
                    onLayout={getCellOnLayoutHandler(index)}
                    key={index}

        {/* View for resend otp  */}
        {resendButtonDisabledTime > 0 ? (
            <Text style={styles.resendCodeText}>Resend Authorisation Code in {resendButtonDisabledTime} sec</Text>
        ) : (
                <TouchableOpacity
                    onPress={onResendOtpButtonPress}>
                    <View style={styles.resendCodeContainer}>

        <View style={styles.button}>
            <Button buttonTitle="Submit"
                onClick={() =>

                } />
        </View>
    </SafeAreaView >

export const styles = StyleSheet.create({

希望对很多人有帮助。快乐编码！！

我解决了这个问题的6位数otp以下切森的答案。首先创建一个数组“otp”，初始化状态为otp ='-'，'-']，然后创建一个otpVal字符串，状态如下

const [otp, setOtp] = useState(['-', '-', '-', '-', '-', '-']);
const [otpVal, setOtpVal] = useState('');

现在渲染otp框的实际逻辑如下。

<TextInput
                    onChangeText={value => {
                        if (isNaN(value)) {
                            return;
                        }
                        if (value.length > 6) {
                            return;
                        }
                        let val =
                            value + '------'.substr(0, 6 - value.length);
                        let a = [...val];
                        setOtpVal(a);
                        setOtp(value);
                    }}
                    style={{ height: 0 }}
                    autoFocus = {true}
                />
                <View style={styles.otpBoxesContainer}>
                    {[0, 1, 2, 3, 4, 5].map((item, index) => (
                        <Text style={styles.otpBox} key={index}>
                            {otp[item]}
                        </Text>
                    ))}
                </View>

otpBoxesContainer和otpBox的样式如下：

otpBoxesContainer: {
    flexDirection: 'row'
},
otpBox: {
    padding: 10,
    marginRight: 10,
    borderWidth: 1,
    borderColor: lightGrey,
    height: 45,
    width: 45,
    textAlign: 'center'
}

现在，由于TextInput的高度设置为0，它不会显示给用户，但它仍然接受输入。我们修改和存储输入的方式，我们可以显示它，就像在单独的输入框中输入值一样。

我也遇到了同样的问题，我设法开发了一个很好的工作解决方案。忽略提供程序，我使用它是为了我自己的目的，只是为了设置表单值。
行为：
1.用户输入第一个pin号
1.下一个输入是聚焦的
1.用户删除号码
1.号码已删除
1.以前的投入是重点

  ));
};
