ios - NSManagedObject and Arrays -

-

मैं निम्नलिखित कोड में ठोकर खाई हूं 

  NSManagedObject * object = [[NSMutableArray Alloc] initWithObjects: @ "पहले", @ "सेकंड", शून्य];   
 मुझे आश्चर्य है कि यह वास्तव में संकलन क्यों कर रहा है और रनटाइम के दौरान कोई भी अपवाद नहीं फेंकता है।  
  po ऑब्जेक्ट   
 > रिटर्न:  
 
 __ NSArrayM 0x17005fc20 & gt; (प्रथम, दूसरा)    
 
 
 उद्देश्य-सी गतिशील रूप से टाइप किया गया है वहाँ एक बेमेल है, और संकलक उस असाइनमेंट पर चेतावनी पैदा करना चाहिए, और किसी भी संदेश पर आप "ऑब्जेक्ट" पास करते हैं जो NSManagedObject का समर्थन नहीं करता है। हालांकि, यह पूरी तरह से वैध है। कृपया इसे ठीक करें।

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

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...
