 func callapi(apiname: string, param: [string : anyobject]?, data: nsdictionary?, withmethod type: string, completionhandler:@escaping (_ code: int, _ error:nserror?, _ response:anyobject?) -> void)      {          mbprogresshud.showadded(to: appdelegateobj.window, animated: true)         let str_url : string = khostpath+apiname          let manager: afhttpsessionmanager = afhttpsessionmanager()          if (type == kreq_post) {              manager.post(str_url, parameters: param, constructingbodywithblock: { (formdata: afmultipartformdata!) in                  if data?.allvalues.count != 0 && data != nil                 {                      let fileurl = nsurl(fileurlwithpath: (data?.valueforkey("filepath"))! as! string)                     try! formdata.appendpartwithfileurl(fileurl, name: (data?.valueforkey("key"))! as! string)                 }                  }, progress: { (nsprogress) in                  }, success: { (task:urlsessiondatatask, responseobject) -> void in                      completionhandler(code: 1, error: nil, response:responseobject)                     mbprogresshud.hidehudforview(appdelegateobj.window, animated: true)                  }, failure: { (task:urlsessiondatatask?, error:nserror) -> void in                      completionhandler(code: 0, error: error, response:nil)                     mbprogresshud.hidehudforview(appdelegateobj.window, animated: true)             })         }         else {              manager.get(str_url, parameters: param, progress: { (nsprogress) in                  }, success: { (task:urlsessiondatatask, responseobject) -> void  in                      completionhandler(code: 1, error: nil, response:responseobject)                     mbprogresshud.hidehudforview(appdelegateobj.window, animated: true)                  }, failure: { (task:urlsessiondatatask?, error:nserror) -> void  in                      completionhandler(code: 0, error: error, response:nil)                     mbprogresshud.hidehudforview(appdelegateobj.window, animated: true)             })         }     }

but getting error 

cannot convert value of type (urlsessiondatatask?,nserror)->void expected argument type '((urlsessiondatatask?,nserror)->void)?'

change error type nserror error. type compatibility changed swift2.3 swift 3.0

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
