cocos2d-x的一个横版项目需呀用到UIImagePickerController
ios直接报错，原因是不支持横版
最初自己写了ImagePickerVIEwController专门的VIEwController来控制这块，通过addSubvIEw竖屏没问题，但是在横屏有很多的问题
通过paush或者presentModalVIEwController切换之后，取得图片之后返回游戏，直接报错OpenGL错误
强制限制ImagePickerVIEwController的横竖屏都没有有效解决该问题，后来直接在RootVIEwController添加UIImagePickerController就好了
解决办法
1、Targets > General > Deployment Info
Device OrIEntation 选中 Portrait 与 Landscape left Landscape Right
