iphone - How do I get a timestamp from an NSString date? -


I have an NSString date ( @ "Monday, 01 February 2010 20:25:37 +0000" / Code>) that I want to convert to a timestamp so that I can better calculate how much time has passed since the present time. How can I change the NSString date to a timestamp value?

This has not been tested in full but it should do the trick. 

  NSDateFormatter * formatter = [[NSDateFormatter alloc] initWithDateFormat: @ "EEE, DD MMM yyyy HH: mm: SSZZZ" allowNaturalLanguage: no]; NSDT * Date = [Formattor Deaththrustring: @ "Mon, 01 Februar 2010 20:25:37 +0000"];

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
