报错信息：
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.

意思是你的组件已经销毁了，你还设置个锤子的值

然后试着用生命周期函数componentWillUnmount处理，发现没卵用

再去查询资料，原因是你在设置值的时候需要把这个值给包装一下，
因为DatePicker 的value属性不能用string直接赋值，用moment包装一下，包装成moment类型的对象(详情点这里)
也就是这样

// 就是用moment方法，对dateString进行包装即可
    onChangeDate = (date: any, dateString: any) => {
        this.setState({
            taskDate: moment(dateString)
        })
    }

完美解决。
