swift3 - Accessing code in Swift 3 Error -


new in xcode 8 beta 4, nserror bridged swift error protocol type. affects storekit when dealing failed skpaymenttransactions. ought check sure error didn't occur because transaction cancelled know whether or not show error message user. examining error's code. error instead of nserror, there no code defined. haven't been able figure out how error code error.

this worked in previous version of swift 3:

func failedtransaction(_ transaction: skpaymenttransaction) {     if let transactionerror = transaction.error {         if transactionerror.code != skerrorcode.paymentcancelled.rawvalue {             //show error user         }      }      ... }

now error error not nserror, code not member.

casting skerror seems working me in xcode 8 , swift 3...

    guard let error = transaction.error as? skerror else {return}     switch error.code {  // https://developer.apple.com/reference/storekit/skerror.code     case .unknown: break     case .paymentcancelled: break     case .clientinvalid: break     case .paymentinvalid: break     case .paymentnotallowed: break     case .cloudservicenetworkconnectionfailed: break     case .cloudservicepermissiondenied: break     case .storeproductnotavailable: break     }

no need rawvalue.

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

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
