React life cycle

1.getDefaultProps

Initialize Settings props

2.getInitialState

Initialize the state of the setting

3.componentWillMount

Called when rendering is completed for the first time

4.componentDidMount

Called after the first rendering is complete, and is called only once, typically for binding time between

5.componentWillReceiveProps

Called when rendering finishes receiving prop again

6.shouldComponentUpdate

I used it for the time being.

7.componentWillUpdate

Called when a new props or state is received

8.componentDidUpdate

Each render completion is called, in the scroll plug-in Iscroll each time the structure of the DOM changes, the overall height changes, so call this method to Reflash

9.componentWillUnmount

Called before the component is clear, the user cleans up the work, or adds the vanishing animation
