ios - Xcode 6 is telling me that UIViewController doesn't have a member named reloadData() -

-

मेरे पास एक दृश्य नियंत्रक है जो कि UICollectionViewController , UICollectionViewDataSource है, और UICollectionViewDelegate ।

हाल ही में Xcode को अपडेट करने के बाद, मुझे अब निम्न त्रुटि मिल रही है:

'(UICollectionView, numberOfItemsInSection: Int) - & gt; निम्नलिखित कोड ( -didCompleteForecast: एक कॉलबैक विधि है) पर 'पुनः लोड' नाम वाले सदस्य का पुनः लोड किया गया नाम 'पुनः लोडडेटा' नहीं है: 

  func didCompleteForecast () {// सामान println ("डेटा वापस मिला") dispatch_async (dispatch_get_main_queue ()) {self.collectionView.reloadData ()}   
 एप्पल के स्वयं के अनुसार  
 धन्यवाद   
 
 
 ऐसा इसलिए है क्योंकि self.colectionView वैकल्पिक प्रकार है (UICollectionView?) ताकि आपको इसे खोलना होगा:  
  self.collectionView! .reloadData ()

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
