ios6下 cocos2d-x 2.0不能横屏解决方案_cocos横屏失效-优快云博客

本文解决在iOS6系统下，Cocos2d-x项目默认变为竖屏显示的问题，通过修改代码实现横屏显示。包括在RootViewController.mm中添加shouldAutorotate方法和supportedInterfaceOrientations属性，以及在AppController.mm中调整窗口显示和根视图控制器配置。

升级到ios6后，发现cocos2d-x的项目都变成竖屏了。之前设置横屏竖屏的方法都不能用了。

这个原因在于在ios6中

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

这个方法已经不能使用了。

解决方案：

在ios包里找到RootViewController.mm

添加如下方法：

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

在AppController.mm文件中的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

方法中

添加：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
    EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]
                                     pixelFormat: kEAGLColorFormatRGBA8
                                     depthFormat: GL_DEPTH_COMPONENT16
                              preserveBackbuffer: NO
                                      sharegroup: nil
                                   multiSampling: NO
                                 numberOfSamples:0 ];

    // Use RootViewController manage EAGLView
    viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
    viewController.wantsFullScreenLayout = YES;
    viewController.view = __glView;

    // Set RootViewController to window
    
    NSString *reqSysVer = @"6.0";
    NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
    
    if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
    {
        [window setRootViewController:viewController];
    }
    else
    {
        [window addSubview:viewController.view];
    }

    
    [window makeKeyAndVisible];

    [[UIApplication sharedApplication] setStatusBarHidden: YES];

    cocos2d::CCApplication::sharedApplication().run();

    return YES;
}
