ios8 - Simple Swipe in Swift - xCode 6 -

-

I'm trying to make a simple swipe-up gesture, I pulled the swipe gesture detector on a UIImage, then I Drag the Ctrl button into my Swift file and create the following action: - 

  @IBAction func swipeDice (Sender: UISwipeGestureRecognizer) {// test display testLabel.text = "Zing"} < / Code>  
 The app runs and runs successfully, but when I do test the gesture, it does anything Does not seem to be in  
 Do all code need to run this gesture? How do I recognize it with a 2 finger swipe?

  Multiplier Inspector  for  UIImage  and tick  User Interaction Enabled :

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
