ios - Add button only in Code? -

-

I'm just trying to add a button to the code in Xcode simulator, it works not only on my device but also Fatal error: unexpectedly unwrapping an optional value while zero found

My code: 

  @ Ibsultile Weak Play Button: UI Button! Override function viewDidLoad () {image.updatedDidLoad () go image = UIImage (name: "playButton.png") UIImage playButton = UIButton.buttonWithType (UIButtonType.System) UIButton playButton.frame = CGRectMake (10, 10, 100 As, 100) // crash here playButton.center = CGPointMake (self.frame.width / 2, self.frame.height / 1.7) playButton.addTarget (self, action is: "transition:", forControlEvents: UIControlEvents TouchUpInside) playButton SetBackgroundImage (Image, forState: UIControlState.Normal) self.view? .addSubview (playButton)}   
 Can someone help me?  
  
 
 
 It does not make sense - if you're using @iBotlett, it means that the storyboard Your button has been created so you do not have to start it:  
  
 go image = UIImage (name: "playButton.png") UIImage playButton = UIButton.buttonWithType (UIButtonType .system) as UIButton playButton.frame = CGRectMake (10, 10, 100, 100) // crash here is playButton.center = CGPointMake (self.frame.width / 2, self.frame.height / 1.7 ) PlayButton.addTarget (self, action: "transition:", forControlEvents: UICon trolEvents.TouchUpInside) playButton.setBackgroundImage (image, forState: UIControlState.Normal) self.view .addSubview (playButton)    
 set above and above the code set in the storyboard Do @ ebayings should be a different method that should be accustomed to your button inside your touch-up in your storyboard.

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
