cocos2d-x在Xcode（iOS ）中设置横竖屏的解决方案

在
RootViewController.mm文件里找到 - (NSUInteger) supportedInterfaceOrientations方法。如果想让程序是竖屏，直接return

UIInterfaceOrientationMaskPortrait。横屏是默认的，当然也可以选择别的，自己跟到源码里找，应该不难。
大概是以下几个
UIInterfaceOrientationMaskPortrait = (1 <<
UIInterfaceOrientationPortrait),
UIInterfaceOrientationMaskLandscapeLeft = (1 <<
UIInterfaceOrientationLandscapeLeft),
UIInterfaceOrientationMaskLandscapeRight = (1 <<
UIInterfaceOrientationLandscapeRight),
UIInterfaceOrientationMaskPortraitUpsideDown = (1 <<
UIInterfaceOrientationPortraitUpsideDown),

UIInterfaceOrientationMaskLandscape = (UIInterfaceOrientationMaskLandscapeLeft |
UIInterfaceOrientationMaskLandscapeRight),

UIInterfaceOrientationMaskAll = (UIInterfaceOrientationMaskPortrait |
UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight |
UIInterfaceOrientationMaskPortraitUpsideDown),

UIInterfaceOrientationMaskAllButUpsideDown = (UIInterfaceOrientationMaskPortrait |
UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight)

其余地方貌似不用改
