ios - How to get VCF data with contact images using CNContactVCardSerialization dataWithContacts: method? -


i'm using cncontacts , cncontactui framework , picking contact via this

cncontactpickerviewcontroller *contactpicker = [cncontactpickerviewcontroller new];               contactpicker.delegate = self;  [self presentviewcontroller:contactpicker animated:yes completion:nil];

and

-(void)contactpicker:(cncontactpickerviewcontroller *)picker didselectcontact:(cncontact *)contact {     nsarray *array = [[nsarray alloc] initwithobjects:contact, nil];     nserror *error;     nsdata *data = [cncontactvcardserialization datawithcontacts:array error:&error];     nslog(@"error_if_any :: %@",error.description); }

this contact object have contact.imagedata , coming in logs. when tried cross check data by

nsarray *contactlist = [nsarray arraywitharray:[cncontactvcardserialization contactswithdata:data error:nil]]; cncontact *contactobject = [contactlist objectatindex:0];

this getting null //contactobject.imagedata

need why i'm getting null , contact has image when check in contacts?

as workaround can create photo field inside of vcard.

nserror* error = nil; nsdata* vcarddata = [cncontactvcardserialization datawithcontacts:@[contact] error:&error]; nsstring* vcstring = [[nsstring alloc] initwithdata:vcarddata encoding:nsutf8stringencoding]; nsstring* base64image = contact.imagedata.base64encoding; nsstring* vcardimagestring = [[@"photo;type=jpeg;encoding=base64:" stringbyappendingstring:base64image] stringbyappendingstring:@"\n"]; vcstring = [vcstring stringbyreplacingoccurrencesofstring:@"end:vcard" withstring:[vcardimagestring stringbyappendingstring:@"end:vcard"]]; vcarddata = [vcstring datausingencoding:nsutf8stringencoding];

for reasons cncontactvcardserialization not use photo of contact. vcard after serialization looks like:

begin:vcard version:3.0 prodid:-//apple inc.//iphone os 9.3.2//en n:contact;test;;; fn: test  contact  end:vcard

after insertion photo field inside vcard get

begin:vcard version:3.0 prodid:-//apple inc.//iphone os 9.3.2//en n:contact;test;;; fn: test  contact  photo;type=jpeg;encoding=base64:<photo base64 string> end:vcard

after insertion contact looks fine in cncontactviewcontroller

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
