xcode - Textview caret/cursor is cut off at the bottom ios8 -

-

I'm struggling with a bug in Xcode 6.0.1. I'm building an app that has a similar view to Apple's compose section in the mail app. I'm using 

  func textViewDidChange (textView: UITextView) {self.tableView.beginUpdates () self.tableView.endUpdates ()}   
 Which is to change its size using cell layout and simple barriers in column view.stimatedROHETET and TableViewRowight = UITTualAutActive Demement Order. I have a cell Mytextview.delagete = self This works flawlessly in my second view where the text has not been entered by the user.  
 The problem is that it seems that the cell carit / cursor is being truncated when it reaches the bottom of the keyboard or screen on the screen. Apart from this, if I press back repeatedly without entering the text then the carpet / cursor disappears almost 6 times, until it scrolls down to me, the cursor is still cut. I have realized that if I put 5 rows of text and then start back from the rows then the text works normally as well. It looks similar to seeing. It seems that there is some difference where it does not auto scroll to the right place. I should also mention that cell and textview are expanding because I can scroll down and see the text. I have already tried to remove other cells, to see if they are related to this problem, but it has no effect. I have worked very hard on this and have come from empty hands. Here is some relevant code.  
  Override function table view (table view: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) - & gt; UITableViewCell {var Seldifier: string? If indexPath.row == 0 {cellidentifier = "tocell"}, then indexPath.row == 1 {cellidentifier = "subjectcell"} if indexPath.row == 2 {cellidentifier = "bodycell"} cell = table view. DEqueueReusableCellWithIdentifier (cellidentifier!) ComposeTableViewCell as if indexPath.row == 0 {cell.tofield! .text = toString cell.tofield? .delegate = self} if indexPath.row == 1 {cell.subjectfield? .delegate = self} if indexPath.row == 2 {cell.bidfield ?. Delegate = self} return cell}    
 
 
 i hope that until Xcode Bug access  do not enter the code here  view.content = CGSizeMake (0,800) // in this way and apply as per the orientation

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
