xcode - Swift- Set Visible menucontroller -

-

I'm trying to display UimenuController but I can not see it. How can i do 

  Give to the menu controller: UIMenuController = UIMenuController.sharedMenuController () menu controller. Menu = Useful = True MenuController.arrowDirection = UIMenuControllerArrowDirection.Down MenuController.setTargetRect (CGRectMake (100, 80, 50, 50), keeping in mind: self.view) Know MenuItem_1: UIMenuItem = UIMenuItem (Title: "Menu", Action: " Delete: ") MenuItems do: NSArray = [Delete] MenuController.menuItems = MenuItems    
 
 
 To actually display the menu, you need to do the following:  
     
  1.  Before calling getFirstResponder () you get your sharedMenuController  
  2.  call menu.setMenuVisible ( True, animated: true) finally  
  3.   
  4.  c anBecomeFirstResponder override override function canPerformAction function   
     Write the function for the selector here is an example  
      someFunc () {beFirstResponder () Menu menu.menuItems = [deleteItem] menu.setTargetRect (CGRectMake (100, 80, 50, and so on): menu item (select "deleteLine" 50), keeping in mind: menu.setMenuVisible (True Animated: True)} function deleteLine () {// Here are some overrides function canBecomeFirstResponder () -> Bull {Return True} Overcoded Fun Canopperfectation (Action: Selector, Sender Sender: An Object?) - & gt; Bool {// You only need to return true for the actions you need, otherwise you can get the full range of // iOS if you can remove the statement here only. If the action == selector ("deleteline") returns {return true} return false}

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
