rn 组件state状态

1、类组件中无需放在构造函数中,若要放在构造函数中和react一样写法也有效
	
		state={
			键值对
		}
2、调用方式和react一样

代码示例:

import React,{Component} from 'react'
import {Text,View,StyleSheet} from 'react-native'

export default class App extends Component{
    
    state={
            name:'jeff',
            type:'帅'
        }
    change(){
        this.setState({type:'超级帅'});
    }
    render(){
        return(
            <>
                <View >
                    <Text onPress={this.change.bind(this)}>{this.state.type}</Text>

                </View>
            </>
        )
    }
}
