react 内存溢出问题教程

警告 ： Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

解决方式

componentWillUnmount = () => {
    this.setState = (state,callback)=>{
      return;
    };
}
