I have created a project with cocos2d 0.99.5 + box2d. When I rotate my iphone, Screen automatically rotated too. So the boxes Flew up into the ceiling.

How to disable auto-rotation?

plz

在 coco2d 0.99.5 中，模板创建了一个名为 GameConfig.h 的文件，您可以在其中选择控制应用旋转的系统。默认是

#define GAME_AUTOROTATION kGameAutorotationUIViewController

现在看看 RootViewController.m 内部，或者你在文件中命名的任何内容。在里面

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

方法，您将看到许多编译器指令#if。#elif查看 kGameAutorotationUIViewController 发送给我们的部分：

#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;

要将游戏保持在单一方向，请将中间的 if 语句更改为：

if( interfaceOrientation == UIInterfaceOrientationPortrait)
    return YES;

或者你决定的任何方向都是你想要的。希望这可以帮助！

我在我的应用程序委托中有这个，无论我以哪种方式转动它，它都保持在横向：

- (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]];
}
