objective c - How Do You Figure Out What the Date Format Is For a Given NSString? -


hey stackoverflow people,

i have date timestamp nsstring following value backend server:

nsstring *date = @"2014-01-27t21:06:59.000-05:00";

i can't life of me figure out date format string above , have been trying use nsdateformatter object 2 following date formats (that have both returned me nil):

format 1: @"yyyy-mm-ddthh:mm:ss.000-05:00";

format 2: @"yyyy-mm-ddthh:mm:ss.sss-ss:ss";

my question is: how heck use given string determine date format you're working with?

try this, works:

@"yyyy-mm-dd't'hh:mm:ss.ssszzzzz"

the -05:00 timezone, need use zzzzz that.

also, because t not part of date, need scape it, use 't' that.

notice hh instead of hh.

find formatters examples here:

http://www.unicode.org/reports/tr35/tr35-25.html#date_format_patterns

about question of how know format, have guess based on see, or ask person providing date.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id).
