ios6下cocos2d & ipad 调用摄像头报错问题 （在竖屏情况下调用Camera 会导致转屏)

  Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'

因为UIImagePickerController是竖屏的，而ipad是横屏的，在ios6.0的横竖屏的问题比较敏感，所以在会挂的。
解决办法：
在supported Interface Orientations选中landscapeLeft和LandscapeRight（不选中的话在iOS5.0下第一次运行会竖屏）
在appdelegate添加
#if __IPAD_OS_VERSION_MAX_ALLOWED >= __IPAD_6_0

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{

return UIInterfaceOrientationMaskAll;


}
#endif
在该viewController和上一层的viewController中添加
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{ 

return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight );

}

-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}

- (BOOL)shouldAutorotate
{
return YES;
}
