Xamarin iOS : Facebook logout issue -


i using xamarin.facebook.ios sdk (v 4.13.1.0) facebook login.

current scenario: in app, once user logs in through facebook credentials , logs out, can hit login , authenticated.

expected scenario: once user logs in through facebook credentials , logs out, if wants login again, needs enter facebook , password once again.

right log out using following code:

nshttpcookiestorage storage = nshttpcookiestorage.sharedstorage;             foreach (nshttpcookie cookie in storage.cookies)              {                 if(cookie.domain == ".facebook.com")                 {                     storage.deletecookie(cookie);                 }         }

but doesn't work. right now, expected result have to:

  1. sign out , close app, open safari , clear history.
  2. sign out , close app, open safari -> goto facebook website ( won't ask credentials has when logged in our app) , logout.

clearly, not best way desired result. can please advise me better approach ??

also, there way set expiry date facebook access token way set expiry date current date time , let user enter credentials again next time login.

thank you.

i upgraded iphone ios 10.1.1 , logout work correctly.

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
