可能的错误是因为您试图在错误的位置渲染<Modal/>组件。尝试像这样渲染模态框:

// ...您的其余代码
    <View style={styles.footer} >
        <TouchableOpacity>
            <Button onPress={() => userInfo.data ? setisModalVisible(true) :
            navigation.navigate(routes.LOGIN, {item:item})}> 发表评论 </Button>
        </TouchableOpacity>
    </View>
    <Modal
        transparent={true}
        animationType='fade'
        visible={isModalVisible}
    > 文本 </Modal>
    </Wrapper>

您必须将状态isModalVisible设置为true,不能在onPress函数内渲染JSX元素。

请测试并查看是否正确,如果不正确,请报告,我们可以尝试找到另一个答案。

英文:

Probably the error is because you're trying to render the <Modal/>component in the wrong place. Try to render the modal like this:

//...rest of your code
    <View style={styles.footer} >
                <TouchableOpacity>
                    <Button onPress={userInfo.data ? setisModalVisible(true) :
                    navigation.navigate(routes.LOGIN, {item:item})}> Post a review </Button>
                </TouchableOpacity>
            </View>
                <Modal
                      transparent={true}
                      animationType='fade'
                      visible={isModalVisible}
                    > Text </Modal>
     </Wrapper>

You have to set the state isModalVisible to true, you can't render an JSX element inside an onPress function.

Test and see if it's correct, if it isn't please report an we can try to find another answer.
