API

Usage in controlled or uncontrolled

All input and interaction class components have controlled usage and uncontrolled usage.

• Controlled usage: component status is affected by external incoming props. The external props changes, so that the components will change, such as:

constructor() {
    super();
    this.state = {
        checked: true
    }
}
change = (value) => {
    this.setState({
        checked:!value
    });
}
//...
render(){
    return (<Switch checked={this.state.checked} onValueChange={this.change}/>)
}

• Uncontrolled usage: The component itself changes freely and changes what is externally changed through the event, such as:

change = (value) => {
    console.log('switch change to: ',value);
}
//...
render(){
    return (<Switch defaultChecked={true} onValueChange={this.change}/>)
}
