React native 错误状态无法更新组件？

我有一个关于国家的问题。每当我导航到一个新页面（主页）并设置onboardingstep的状态时，我都会收到一个错误，说我的状态不好（），因此无法更新。此处是设置状态和错误日志的文件

这是我的入职模板，由入职人员呈现，然后显示在应用程序中：

import React, {useState} from 'react'
import {View,ScrollView,StyleSheet} from 'react-native'

import Logo from '../ui/molecules/Logo'
import OnboardingInfo from '../ui/organisms/OnboardingInfo'
import OnboardingMedia from '../ui/organisms/OnboardingMedia'
import Button from '../ui/atoms/Button'


import {  useNavigation } from '@react-navigation/native'
            
let currentStep : JSX.Element;
export default function OnboardingTemplate(){
    const navigation :any = useNavigation();
    const [onboardingStep, setOnboardingStep]:any = useState(0);


    if (onboardingStep == 0){
        currentStep=(
            <ScrollView contentContainerStyle={styles.container}> 
                <Logo/>   
                <OnboardingInfo/>
                <View style={styles.topDistance}>
                    <Button onPress={() => setOnboardingStep(1)} 
                    style={styles.inputBtn} title="Fortsæt (1/2)"/>
                </View>
            </ScrollView>
        )    
    } else if (onboardingStep == 1){
        currentStep=(
            <ScrollView contentContainerStyle={styles.container}> 
                <Logo/>   
                <OnboardingMedia/>
                <View style={styles.topDistanceSmall}>
                    <Button onPress={() => setOnboardingStep(2)} 
                    style={styles.inputBtn} title="Opret profil"/>
                </View>
            </ScrollView>
        )
    } else {
        // error occours when this part is run
        navigation.navigate("explore");
    }

    return (currentStep) ? currentStep : null ;
}

    
// styling etc...

我怀疑发生这种情况是因为您正在导航到另一个视图，然后在该组件实际开始渲染null之前进行渲染。我建议将navigate（）调用与onboardingStep一起作为依赖项放在useEffect中，以便在按下按钮时运行逻辑。我还建议修改渲染逻辑，以便在每次渲染时不会完全替换模板：相反，使用标记内的条件表达式交换样式和子组件，并直接返回，而不是将其指定给currentStep
