最近在做React-Native项目，每次手动配置xcode的appicon图，感觉很是乏味，重复的操作都应该被机器替代，所以就找度娘了，折腾了半天还是没有找到相关的插件，偶然看了一下cordova的api发现一个很好使的插件：cordova-icon，他可以自动生成xcode下的各种appicon，很神奇，然后就参考这个插件自己捣鼓了一个React-Native下针对ios生成appicon适配的npm包，生成appicon之后修改了对应的contents.json这样xcode倒入项目之后就不用再手动拖入对应的icon了，解放双手，附上插件用法和配置截图截图&插件信息&地址：
react-native-autoicon
Automatic icon resizing for ReactNative. Create an icon in the root folder of your ReactNative project and use ReactNative-icon to automatically resize and copy it for all the platforms your project supports (currenty works with iOS).
this project inspired by cordova-icon thanks for alex101
$ brew install imagemagick
$ sudo npm install react-native-autoicon -g
Create an icon.png file in the root folder of your ReactNative project.
Then run:
$ autoicon
# if your projectname not package.json name you can add params
$ autoicon --name 'your project name'
