IOS目录中RootViewController.mm
//显示竖屏
- (BOOL) shouldAutorotate {
return NO;
}

//显示横屏
- (BOOL) shouldAutorotate {
return YES;
}

还有一个屏目适配:

AppDelegate 中:

CCDirector* pDirector = CCDirector::sharedDirector();

CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

pDirector->setOpenGLView(pEGLView);

pEGLView->setDesignResolutionSize(320 ,480, kResolutionNoBorder);//这个是跟据图片的大小来设置
