推荐答案

存储脱机数据的最简单方法是使用

The easiest way to store offline data is using the AsyncStorage, it's basically a key value storage, super easy to use. You can save json in there or any other text, for example:

AsyncStorage.setItem('data', JSON.stringify([{id: 1, name: 'a', src: ''}]));

然后，以后，您可以像这样获取数据:

Then, later on, you can get that data like this:

AsyncStorage.getItem('data', (err, result) => {
  console.log(JSON.parse(result));
});

对于简单的应用程序，这已经绰绰有余

For simple apps, this is more than enough
