RN开发中难免会用到图标，今天我们来集成github上比较受欢迎的一个强大的icons库。

废话不多说，现在开始集成：
第一步：在react-native 工程目录下通过npm安装react-native-vector-icons
npm install react-native-vector-icons --save
第二步：分别为android和ios做一些相应的配置
Android：
在android/app/build.gradle
中增加如下脚本：
project.ext.vectoricons = [
iconFontNames: [ 'MaterialIcons.ttf', 'EvilIcons.ttf' ] // Name of the font files you want to copy
]
apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"
在node-modules 中找到
react-native-vector-icons库，将Fonts 文件夹拷贝到android/app/src/main/assets/fonts
如果没有assets/fonts 新建即可
在android/settings.gradle中增加如下脚本，
include ':react-native-vector-icons'
project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')
include ':react-native-vector-icons'的作用时在编译android项目的时候
react-native-vector-icons会作为一个module加入编译。
project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')是指定
react-native-vector-icons的具体路径在android/app/build.gradle添加：compile project(':react-native-vector-icons')
apply plugin: 'com.android.application'
android {
...
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile "com.android.support:appcompat-v7:23.0.1"
compile "com.facebook.react:react-native:+" // From node_modules
....
compile project(':react-native-vector-icons')
}
最后一步：在android/app/src/main/java/你的包/MainApplication.java中添加
import com.oblador.vectoricons.VectorIconsPackage;
new VectorIconsPackage()
代码如下：
package com.myapp;
import com.oblador.vectoricons.VectorIconsPackage;
....
@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage()
, new VectorIconsPackage()
);
}
}
然后在此运行项目即可。
IOS集成：
通过，拷贝Fonts到xcode的Images.xcassets中然后在Info.plist中添加如下代码
Information Property List 添加一个Item
即可，编译一下，然后运行项目。
一下是我的使用demo代码：
创建一个使用该库来实现icon的TabIcon
import React, {
PropTypes,
Component
} from 'react';
import {
Text,
View,
StyleSheet
} from 'react-native';
import Icon from 'react-native-vector-icons/Ionicons';
export default class TabIcon extends Component {
render() {
return (
{this.props.tabTitle}
);
}
}
TabIcon.propTypes = {
selected: PropTypes.bool,
tabTitle: PropTypes.string.isRequired,
iconName: PropTypes.string
};
const styles = StyleSheet.create({
container: {
flexDirection: 'column',
alignItems: 'center',
justifyContent: 'center'
},
title:{
fontSize:14,
}
});
如下使用即可
/**

import React, { Component } from 'react';
import {
StyleSheet
} from 'react-native';
import {
Router,
Scene,
Modal,
ActionConst
} from 'react-native-router-flux';
import { connect } from 'react-redux';
import HomeView from '../pages/home';
import PublishView from '../pages/publish';
import ProfileView from '../pages/profile';
import MessageView from '../pages/message';
import DiscroverView from '../pages/discrover';
import TabIcon from '../components/TabIcon';
const RouterWithRedux = connect()(Router);
/**
* 定义基本的样式
* @param props
* @param computedProps
* @returns {{flex: number, backgroundColor: string, shadowColor: null, shadowOffset: null, shadowOpacity: null, shadowRadius: null}}
*/
const getSceneStyle = (props, computedProps) => {
const style = {
flex: 1,
backgroundColor: '#fff',
shadowColor: null,
shadowOffset: null,
shadowOpacity: null,
shadowRadius: null,
};
if (computedProps.isActive) {
console.log(computedProps)
style.marginTop = computedProps.hideNavBar ? 0 : 64;
style.marginBottom = computedProps.hideTabBar ? 0 : 50;
}
return style;
};
export default class App extends Component{
// 构造
constructor(props) {
super(props);
// 初始状态
this.state = {
selectedTab: 'home',
};
}
render(){
return(
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
tab_image: {
height: 28,
width: 28,
},
tabBarStyle: {
borderTopWidth: 0.5,
borderColor: '#b7b7b7',
backgroundColor: 'white',
opacity: 1
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5
}
});
