React-Navigation使用出现Warning: isMounted(...) is deprecated in plain Javascript Classes

 

使用React-Navigation出现以下问题:

Warning: isMounted(...) is deprecated in plain Javascript Classes. Instead, make sure to clean up subscriptions and pending requests in componentWillUnmount to prevent memory leaks.

github上issue : https://github.com/react-navigation/react-navigation/issues/3956

这里的issue说的很明白了,这个问题不是组件本身的问题是React Native 的bug.可查看rn的issue里面存在此问题.

目前解决办法就是忽略警告（坐等fb解决这个bug了）:

在index.js上方加上如下代码即可;

import { YellowBox } from 'react-native';YellowBox.ignoreWarnings(['Warning: isMounted(...) is deprecated', 'Module RCTImageLoader']);
