Question

我有这段代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];

    CGRect screenFrame = [UIScreen mainScreen].bounds;
    _controller = [[UIViewController alloc] init];
    _controller.view = [[UIView alloc] initWithFrame:screenFrame];

    SKView *skView = [[SKView alloc] initWithFrame:screenFrame];
    skView.backgroundColor = [SKColor blueColor];
    [_controller.view addSubview:skView];

    self.window.rootViewController = _controller;

    [self.window makeKeyAndVisible];

    return YES;
}

但是我没有看到蓝屏，而是看到了灰色屏幕。

我做错了什么？

感谢。

我认为您需要从SKView中展示SKScene才能看到颜色。在AppDelegate中这样做很奇怪，但也许不是吗？我从未见过那种东西放在那里。

我有这个，它工作正常。

    self.window.backgroundColor = [UIColor whiteColor];

CGRect screenFrame = [UIScreen mainScreen].bounds;
UIViewController *_controller = [[UIViewController alloc] init];
_controller.view = [[UIView alloc] initWithFrame:screenFrame];

SKView *skView = [[SKView alloc] initWithFrame:screenFrame];
SKScene *currentScene = [[SKScene alloc]initWithSize:skView.bounds.size];
currentScene.backgroundColor = [SKColor blueColor];
[_controller.view addSubview:skView];
[skView presentScene:currentScene];

self.window.rootViewController = _controller;

[self.window makeKeyAndVisible];


return YES;

如何在应用程序中将SKView添加到控制器的视图中：didFinishLaunchingWithOptions：？
