cocos2d-x横版项目调用 ios UIImagePickerController

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

2、代码RootViewController.h

#import <UIKit/UIKit.h>

@interface RootViewController : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate> {

- (BOOL) prefersStatusBarHidden;
