ios - Swift UIWebView initial zoom scale -

-

hey asked similar question days ago no on me , no i'm think im closer problem. have webview on rootviewcontroller , saved values zoom scale , position of local pdf, want set webview values when appears tried following.

   override func viewdidappear(animated: bool) {      dolayoutthings()   }     func dolayoutthings(){      if(defaults.objectforkey("positiony") != nil){           webview.scrollview.setzoomscale(defaults.objectforkey("zoomlevel") as! cgfloat, animated: false)         let offest = cgpoint(x: defaults.objectforkey("positionx") as! cgfloat, y: defaults.objectforkey("positiony") as! cgfloat)         webview.scrollview.setcontentoffset(offest, animated:false)         println(defaults.objectforkey("zoomlevel") as! cgfloat)         }

i know there correct values saved userdefaults webview looks if didn't make scrolling or zooming. i'm happy solution ideas.

setting zoom scale in viewdidappear fine cannot set contentoffset before web view has loaded content. have set delegate on uiwebview , set contentoffset in delegate method:

override func viewdidload() {    webview.delegate = self }  func webviewdidfinishload(webview: uiwebview) {     let offset = cgpoint(x: defaults.objectforkey("positionx") as! cgfloat, y: defaults.objectforkey("positiony") as! cgfloat)     webview.scrollview.setcontentoffset(offset, animated: false) }

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.
