[ios.cocos2d + box2d]如何禁用自动旋转？

Question

我已经用cocos2d 0.99.5 + box2d创建了一个项目。 当我旋转我的iphone时，屏幕也自动旋转。 所以盒子飞入天花板。

如何禁用自动旋转？

我有这个在我的应用程序委托和它停留在景观不管我把它哪条路：

- (void) applicationDidFinishLaunching:(UIApplication*)application 
{ 
    // CC_DIRECTOR_INIT() 
    // 
    // 1. Initializes an EAGLView with 0-bit depth format, and RGB565 render buffer 
    // 2. EAGLView multiple touches: disabled 
    // 3. creates a UIWindow, and assign it to the "window" var (it must already be declared) 
    // 4. Parents EAGLView to the newly created window 
    // 5. Creates Display Link Director 
    // 5a. If it fails, it will use an NSTimer director 
    // 6. It will try to run at 60 FPS 
    // 7. Display FPS: NO 
    // 8. Device orientation: Portrait 
    // 9. Connects the director to the EAGLView 
    // 
    CC_DIRECTOR_INIT(); 

    // Obtain the shared director in order to... 
    CCDirector *director = [CCDirector sharedDirector]; 

    // Sets landscape mode 
    [director setDeviceOrientation:kCCDeviceOrientationLandscapeLeft]; 

    // Turn on display FPS 
    [director setDisplayFPS:YES]; 

    // Turn on multiple touches 
    EAGLView *view = [director openGLView]; 
    [view setMultipleTouchEnabled:YES]; 

    // Default texture format for PNG/BMP/TIFF/JPEG/GIF images 
    // It can be RGBA8888, RGBA4444, RGB5_A1, RGB565 
    // You can change anytime. 
    [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888];  


    [[CCDirector sharedDirector] runWithScene: [HelloWorld scene]]; 
}

在coco2d 0.99.5，模板创建一个名为GameConfig文件。 h，在那里你可以选择什么系统控制应用程序的旋转。默认是

#define GAME_AUTOROTATION kGameAutorotationUIViewController 

现在看看RootViewController.m，或者你在文件中命名它的任何东西。在

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 

方法，你会看到一些#if和#elif编译器指令。检查出kGameAutorotationUIViewController向我们发送的部分：

#elif GAME_AUTOROTATION == kGameAutorotationUIViewController 
// 
// EAGLView will be rotated by the UIViewController 
// 
// Sample: Autorotate only in landscpe mode 
// 
// return YES for the supported orientations 
if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft || 
    interfaceOrientation == UIInterfaceOrientationLandscapeRight) 
    return YES; 

// Unsupported orientations: 
// UIInterfaceOrientationPortrait, UIInterfaceOrientationPortraitUpsideDown 
return NO; 

为了让你的游戏在一个单一的方向，改变中的if语句改为：

if(interfaceOrientation == UIInterfaceOrientationPortrait) 
    return YES; 

或者是其他的方向，你决定它是你想。希望这可以帮助！
