### 支付宝返回应用 iOS 设置
> ⚠️ 如果用户从 `支付宝App` 跳转到 `商家APP`，是通过系统功能切换，而不是通过 `支付宝APP` 功能键返回 `商家APP`，回调函数是不起作用的，可通过 [`AppState.addEventListener`](https://github.com/uiwjs/react-native-uiwjs-alipay/blob/b8b5b3e6e53bb23d1503cd9c565ad8f2132e2404/example/App.js#L6-L24) 监听事件来请求后台 API，来优化这一用户体验。
1. 在代码中设置支付宝 `URL Schemes`，下面实例为 `ap2021001172656340` 为定义的 `scheme`
```js
