您可以利用权限模块来验证用户是否允许或拒绝您的应用调度通知的权限。以下是执行此操作的示例代码：

import * as Permissions from 'expo-permissions';
import { Notifications } from 'expo';

async function checkNotificationPermission() {
  const { status } = await Permissions.getAsync(Permissions.NOTIFICATIONS);
  if (status === 'granted') {
    console.log('Notification permission granted');
  } else {
    console.log('Notification permission not granted');
  }

  const isEnabled = await Notifications.isEnablesAsync();
  if (isEnabled) {
    console.log('Notifications enabled');
  } else {
    console.log('Notifications disabled');
  }
}
