sprite kit - Scene size in Xcode 6 / SpriteKit / Swift -

-

I should be really simple stuff in Xcode, I'm trying to add a ghost in this case. And to sit in the bottom left corner: 

  var groundTestxture: SKTexture = SKTtexture (imageNamed: "dirt-block") var Ground: SKSpriteNode = SKSpriteNode (texture: a mixture of ground) ground .position = CGPointMake (ground.size.width / 2, Ground size.height / 2) self.addChild (ground)   
 It does not show anything, so what I saw is the scenario dimension And self. The frame size.width and the self.frame.size.height are the width of 1024 and the height of 768 are returned, regardless of orientation.  
 I want to decide it in landscape mode if it makes a difference in answering?  
 Obviously I remember a very basic idea to set up this scene, if anybody can put light, then it will be very much appreciated.  p> Thank you.   
 
 
 You have to edit GameViewController:  
  viewDidLoad Exclude  and  everything from  super.viewDidLoad ()   
  overwrite  viewWillLayoutSubviews   
  override func viewWillLayoutSubviews () {super.viewWillLayoutSubviews () if the view = GameScene.unarchiveFromFile ("GameScene")? GameScene {// Configure Scene Var SkView as self.view SKView skView.showsFPS = true skView.showsNodeCount = true / * Spread kit applies additional customization to improve presentation performance * / skView.ignoresSiblingOrder = True / * set the scale scale to fit the window * / scene. Size = skView.bounds.size scene.scaleMode = .SpectVill skView.presentScene (view)}}   
 its In addition you should set the visual size as you can see  
  scene.size = skView.bounds.size   
 hopefully It helps  
 There is also a great tutorial where it is explained further: (Chapter 1 or 2)

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
