ios - Displaying The Date with NSDateFormatter -

-

what i'm trying display date , time similar see within facebook. however, xcode displaying error:

use of unresolved identifier 'creator'.

here's function i'm having trouble with: 

override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("postcell", forindexpath: indexpath) as! postcell     cell.post = posts[indexpath.row]     cell.index = indexpath.row      var dataformatter:nsdateformatter = nsdateformatter()     dataformatter.dateformat = "yyyy-mm-dd hh:mm"     cell.timestamplabel.text = dataformatter.stringfromdate(creator.createdat)      return cell }

an error wasn't displaying until typed out second last line of code. specifically, know error being caused creator, believe timestamplabel culprit because didn't change color person following along in video. i'm utilizing parse store users data , creator 1 of categories have in parse. hoping point me in right direction i've spent way long on that's simple.

the culprit not timestamplabel. culprit creator object.

use of unresolved identifier 'creator'

means object not defined in current scope. in case creator object. creator should defined.

assuming youtube video , code posts object array of parse objects(pfobject)

  override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {      let cell = tableview.dequeuereusablecellwithidentifier("postcell", forindexpath: indexpath) as! postcell     cell.post = posts[indexpath.row]     cell.index = indexpath.row     //---------------------------add this-------------------     var creator = cell.post pfobject     //------------------------------------------------------      var dataformatter:nsdateformatter = nsdateformatter()     dataformatter.dateformat = "yyyy-mm-dd hh:mm"     cell.timestamplabel.text = dataformatter.stringfromdate(creator.createdat)       return cell }

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
