我正在使用AsyncStorage.clear()它在 Android 上运行良好，但是当使用 iOS 平台（真实设备）运行时，我收到了这个错误，并且在网上找不到任何关于它的信息。

我认为当存储从未使用过时 clear 抛出异常是很糟糕的。至少我的想法是这样的？

所以继续我修改了代码，删除了 .clear() 的使用并将其替换为 AsyncStorage.getAllKeys().then(AsyncStorage.multiRemove)

如果有人知道发生了什么，我仍然想要一个理由。

当 AsyncStorage 为空时...

AsyncStorage.clear()
iOS 上的错误，但 Android 上的错误。

AsyncStorage.getAllKeys().then(AsyncStorage.multiRemove)
Android 上的错误，但 iOS 上的错误。

我们的解决方案...

import {  Platform } from 'react-native';
import AsyncStorage from '@react-native-community/async-storage';

const asyncStorageKeys = await AsyncStorage.getAllKeys();
if (asyncStorageKeys.length > 0) {
  if (Platform.OS === 'android') {
    await AsyncStorage.clear();
  }
  if (Platform.OS === 'ios') {
    await AsyncStorage.multiRemove(asyncStorageKeys);
  }
}
