Per the documentation, there are two ways you can use the AppState.
根据文档，有两种方法可以使用AppState。
- Accessing
AppState.currentStateto get the current state (kept updated). - 访问AppState.currentState以获取当前状态（保持更新）。
- Adding an event listener to the changes to AppState through
AppState.addEventListener(type, handler). - 通过AppState.addEventListener（type，handler）向AppState的更改添加事件侦听器。
If you need it once, use the first one. However, if you need to check for changes use the second.
如果您需要一次，请使用第一个。但是，如果您需要检查更改，请使用第二个。
