ios - Cannot invoke" 'setViewController' with an argument list of type [AnyObject] -

-

"cannot invoke" 'setviewcontroller' argument list of type '([anyobject], direction: uipageviewcontrollernavigationdirection, animated: bool, completion: nil)'"

i got error in xcode 7 beta 3 @ line of code:

self.pageviewcontroller.setviewcontrollers(viewcontrollers [anyobject], direction: uipageviewcontrollernavigationdirection.forward, animated: true, completion: nil)

this rest of code:

pageimages = nsarray(objects:"screenshot01","screenshot02","screenshot03")          self.pageviewcontroller = self.storyboard?.instantiateviewcontrollerwithidentifier("mypageviewcontroller") as! uipageviewcontroller          self.pageviewcontroller.datasource = self          var initialcontenviewcontroller = self.pagetutorialatindex(0) tutorialpagecontentholderviewcontroller          var viewcontrollers = nsarray(object: initialcontenviewcontroller)           self.pageviewcontroller.setviewcontrollers(viewcontrollers [anyobject], direction: uipageviewcontrollernavigationdirection.forward, animated: true, completion: nil)          self.pageviewcontroller.view.frame = cgrectmake(0, 100, self.view.frame.size.width, self.view.frame.size.height-100)          self.addchildviewcontroller(self.pageviewcontroller)         self.view.addsubview(self.pageviewcontroller.view)         self.pageviewcontroller.didmovetoparentviewcontroller(self)

i don't error if run same code in xcode 6 , can't figure out why.

the signature looks like:

func setviewcontrollers(_ viewcontrollers: [uiviewcontroller]?,               direction direction: uipageviewcontrollernavigationdirection,                animated animated: bool,              completion completion: ((bool) -> void)?)

so why casting [anyobject]?

try

self.pageviewcontroller.setviewcontrollers(viewcontrollers [uiviewcontroller], direction: uipageviewcontrollernavigationdirection.forward, animated: true, completion: nil)

depending on type of viewcontrollers might need use as!

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...

mercurial graft feature, can it copy? -

-
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.
