ios - Deleting Rows in UITableView Swift 3 -


okay im making app add items cart , updates add. adding fine, cant deleting work. in cart cell need remove 3 arrays, doesn't seem problem because keep getting error:

"terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'invalid update: invalid number of rows in section 0. number of rows contained in existing section after update (1) must equal number of rows contained in section before update (1), plus or minus number of rows inserted or deleted section (0 inserted, 1 deleted) , plus or minus number of rows moved or out of section (0 moved in, 0 moved out).'"

i'm not sure i'm doing wrong here. i've followed few tutorials , seem doing same thing. appreciated in advance.

heres of code:

//declaring arrays show in cell var cartkeys = [string]() var cartvalues = [string]()  var deets = [[string]]() var count = 0   //populating arrays original arrays  func populatecart(){      (key,value) in menustore.shared.cart {          self.cartkeys.append(key)         self.cartvalues.append(value)     }       in menustore.shared.cartanditems{         (k,v) in {             deets.append(v)         }     }      print("deets \(deets)")      c in cartview.visiblecells {          count += 1      }  }   func tableview(_ tableview: uitableview, commit editingstyle: uitableviewcelleditingstyle, forrowat indexpath: indexpath) {      switch tableview{      case cartview:         if editingstyle == .delete{             let index = indexpath.row             print(index)              cartkeys.remove(at: index)             cartvalues.remove(at: index)              deets.remove(at: index)               tableview.deleterows(at: [indexpath], with: .automatic)          }   func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {     switch tableview{      case cartview:         let cartcell = tableview.dequeuereusablecell(withidentifier: "cartcell", for: indexpath) as? cartcell           cartcell?.carttitle.text = cartkeys[(indexpath nsindexpath).row]         cartcell?.cartprice.text = cartvalues[(indexpath nsindexpath).row]         cartcell?.cartdetails.text = deets[count].joined(separator: ", ")            return cartcell!

ps. if wants replacing visible cells call thatd great. id loop through cells if not visible on screen.

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
