Swift iOS take in a input and use it for function name -

- 

func callfunctionname(parameters: string) -> returntype {     var somevalue = parameters     var returnvalue = somevalue()      return returnvalue }

is there way take in input , use function name?

example: let input green, want call function green. if input red call function red etc...

or have huge if statement check each input call different functions

this not possible in swift. have store functions want call in your own dictionary, , use functions name.

a "huge statement" might feasible small number of functions, , perform faster, ideal approach store them in dictionary.

however, if dealing objects:

if exampleobject.respondstoselector("examplefunction") {     exampleobject.performselector("examplefunction") }

this approach works classes, objective-c or swift.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
