如何使用react native在ios上固定边界半径？

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

const CustomComponent = () => {
  return (
    <View style={styles.container}></View>
  );
};

const styles = StyleSheet.create({
  container: {
    width: 200,
    height: 200,
    borderRadius: 100, // 设置边界半径为100
    backgroundColor: 'red',
  },
});

const App = () => {
  return (
    <View style={styles.appContainer}>
      <CustomComponent />
    </View>
  );
};

const styles = StyleSheet.create({
  appContainer: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
