ios - xCode 6 centre of image not working -

-

I have long been upgraded to Xcode 6. When I had Xcode 5, the game was working fine, and it works fine on iOS 7, but this does not work on Xcode 6 / iOS 8. Ive got an arc4random (), which does not work - this means to select a random number between 9 and in any number it's an image change x and y coordinate - so i have other versions of arc4random () Tried to use, but they never worked, though I am confused now because it selects a random number, and it runs the switch statement correctly, but the coordination of the image Does not change ?? So whether it's my arc4random () or Center does not work on 8 / Xcode 6 ?? (I am using objective- c and not swift) 

  - (IBAction) button: (ID) sender {int place = arc4random ()% 9; NSLog (@ "number is:% i", place); Switch (Place) {Case 0: NSLog (@ "One is selected"): Image. Center = CP point make (10,10); break; Case 1: Image. Center = CGPExMake (20,20); NSLog (@ "Two has been selected"); break; Etc ...}    
 
 
 Could it be that some confusion about naming is? What if you want to change the name of your UIImageView object  Image ?

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
