我正在创建我的第一个SpriteKit游戏,这就是我想要做的:
1.删除默认的Main_iphone和Main_ipad故事板
>从info.plist中删除Main_iphone和Main_ipad列表.
>从主界面下删除Main_iPhone.storyboard
部署信息.
2.在didFinishLaunchingWithOptions下的AppDelegate.m中添加以下代码
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[CMViewController alloc] init];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
3.在viewController.m中配置SKScene
-(void)viewWillLayoutSubviews{
[super viewWillLayoutSubviews];
//Configure the view.
SKView* skView = (SKView*)self.view;
//Create and configure the scene.
SKScene* scene = [CMHomeScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
//Present the scene.
[skView presentScene:scene];
}
运行时错误
-[UIView presentScene:]: unrecognized selector sent to instance 0x155854d0
*** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[UIView presentScene:]: unrecognized selector sent to instance 0x155854d0’

self.view = [[SKView alloc] initWithFrame:self.view.frame]在 – (void)loadView下
最佳答案 您已分配SKView * skView =(SKView *)self.view.
我相信self.view不是SKView的子类,所以简单地进行类型转换会将你的SKView指向UIView.
虽然构建代码会很成功,但你肯定会得到运行时错误,因为你的SKView会发现self.view隐藏了它的真实身份(UIView)在一个零指针SKView后面.
您可能想要将3.配置视图更改为以下内容:
- (void)viewWillLayoutSubviews
{
// Configure the view.
SKView* skView = [[SKView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Create and configure the scene.
SKScene* scene = [CMHomeScene sceneWithSize:skView.bounds.size];
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
[self.view addSubview:skView];
}
