获取本地图片和调用相机的代码

看自己前面标题写的上传头像，实际都没有完成，现在回头看看全都是瞎扯的，只是刚开始用的时候出现的一些问题，现在上一下获取本地相机并且上传图片的代码。

本文参考：https://github.com/react-community/react-native-image-picker

还有这个组件需要配置的东西，可以参考：http://www.cnblogs.com/shaoting/p/6148085.html

图片上传的时候react-native-image-picker这个插件的时候ios上的会出现闪退现象。

可以给大家一个网址，这个网址上已经很清晰的解决了
