设置正确的 cocos2d 方向 [英] setting proper cocos2d orientation

问题描述

在我的 cocos2d 应用程序中，在我的应用程序委托的 applicationDidFinishLaunching 方法中，我通过 [director setDeviceOrientation:kCCDeviceOrientationPortrait] 设置方向，因为我真的只想要纵向.但是，Apple 拒绝了我的应用，说它也必须支持倒置肖像.

In my cocos2d application, inside the applicationDidFinishLaunching method for my app delegate, I set the orientation via [director setDeviceOrientation:kCCDeviceOrientationPortrait] because I really only want portrait. However, Apple rejected my app saying it must support upside down portrait as well.

不过，我不确定我是如何检测到这一点的.读取 currentDevice 方向似乎返回了一个未知的方向，所以我的问题是双重的:

I'm not certain how I detect this, though. Reading the currentDevice orientation seems to return an unknown orientation, so my questions are twofold:

1) 我应该如何检测方向，以便我可以正确地将其设置为纵向或倒置纵向(它将永远保持不变).

1) How am I supposed to detect the orientation so I can properly set it to either portrait or upsidedown portrait (where it will stay for good).

2) 我怀疑启动画面会出现问题，因为它是在我到达委托中的这一点之前加载的.如何正确检测方向以便设置正确的初始屏幕?

2) I suspect I'll have an issue with the splash screen because it's loaded before I reach this point in the delegate. How can I properly detect the orientation so I can set the right splash screen?

推荐答案

我只能编辑代码来解决你的第一个问题..我希望你使用.99.5..

I can only edit the codes to fix your first question.. i hope you are using .99.5..

在RootViewController.h中，在函数中

in RootViewController.h, in the function

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

寻找这一行:

#elif GAME_AUTOROTATION == kGameAutorotationUIViewController
{
return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );
}

改成

    return ( UIInterfaceOrientationIsPortrait( interfaceOrientation ) );
