Create SKView programmatically?

问题

I like my code to be explicit so I want to remove the storyboard file and create SKView programmatically.

What I have tried so far:

1. I created a SpriteKit game project in xcode.
2. Deleted the storyboard file.
3. Deleted sroryboard property from Info.plist

4. Added this code found in an example to the AppDelegate:

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
       _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
       AppViewController *viewController = [[AppViewController alloc] init];
       viewController.edgesForExtendedLayout = UIRectEdgeNone;
       _window.rootViewController = viewController;
       [_window makeKeyAndVisible];
       return YES;
   }
   

5. Added this code to the AppViewController:

   -(void) loadView
   {
       self.view = [[SKView alloc] init];
   } 
   

The app starts but then crashes on the creation of first sprite with the following warning

EXC_BAD_ACCESS

I think there should be some good examples of how to do this, but I have not found any for the SpriteKit yet.

回答1:

I fixed the problem by setting a frame to the view:

- (void) loadView
{
    self.view = [[SKView alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
}

Here is a working example project in Swift
