1. Basic knowledge of iOS is required.

2. JSX syntax

3. Virtual DOM, one-way data injection (virtual DOM to real DOM)

4. React knowledge view, can be used in conjunction with other class libraries

5. Important Methods:

A. render ();--Returns the components of some columns.

B. this.props;--Gets the data that the parent component passes to the child component.

C. this.setstate ({data:data});--For dynamic update status, setting data; (UI is updated automatically after setting)

D. Getinitialstate ();---only once for the lifetime of the entire component, to initialize the data;

E. Componentdidmount ();--automatically invoked after render, used to asynchronously fetch data and update data;

6. Execution order

Getinitialstate () Initialize data--〉render () render initialization data--〉componentdidmount () asynchronously Get Data--〉setstate () Update data

7. How do I communicate between components?

For example:

<parent><child/></parent>

Parent component can get to subcomponent: This.props.children
