28. App-specific visual states Visual States Visual states 는 UI 와 코드 를 분리해 주죠. 코드에서 수동으로 엘리먼 트 이동하고, 크기변경하고 하는 대신에 간단히 이 변 경사항들을 처리하는 Storyboard 를 가진 visual state 로 변경하는 게 깔끔 하죠.

29. Setting visual states from code Use constants Sizes and state names will almost certainly change during design iterations

32. Handling the SizeChanged event 핸들러 제거하는 것 잊지 마세요 ! 팁 : 모든 닷넷 프로그램에서 메모리 누수가 발생하는 흔한 원인 중 하나가 제대로 이벤트 핸들러를 제거 하지 않는 것이다. 싱글턴 객체나 정적 클래스의 이벤트에 대한 핸들러는 꼭 제거합시다.

34. 4 Speech Synthesis

35. Speech synthesis  Voice  David(en-US, 남성 )  Zira(en-US, 여성 )  Hazel(en-UK, 여성 )  Heami(ko-KR, 여성 )  외 13 개국 음성 지원

36. Code Speech synthesis  단순 텍스트 음성 출력  synthesizeTextToStreamAsync  PC 의 위치 설정에 따라 음성 지원 var synth = new Windows.Media.SpeechSynthesis.SpeechSynthesizer(); SpeechSynthesisStream stream = await synth.SynthesizeTextToStreamAsync("Welcome!"); media.SetSource(stream, stream.ContentType); media.Play();

37. Speech synthesis  SSML(Speech Synthesis Markup Language)  synthesizeSsmlToStreamAsync  음성 특징, 발음, 볼륨, 피치, 비율 / 속도, 강도 Code string Ssml = @" " + " Welcome! Shinyoung" + " " + "Have a good time" + " "; var synth = new Windows.Media.SpeechSynthesis.SpeechSynthesizer(); SpeechSynthesisStream stream = await synth.SynthesizeSsmlToStreamAsync(Ssml); media.SetSource(stream, stream.ContentType); media.Play();

38. 5 Contact & Appointment

39. Contact  People 앱을 통한 연락처 관리  이메일 및 소셜 계정의 연락처 연동됨  모든 연락처의 추가 / 수정 / 삭제  ContactPickerUI 를 통한 연락처들 호출  ContactManager.ShowContactCard() 를 통해 바로 원하는 연락처의 ContactCard 를 호출  대부분의 사용자는 개인정보 유출에 대한 우려로 앱 자체에서 연락처정보의 관리 / 보호 / 저장 하는 것을 원하지 않음.

40. Contact Picker  Appxmanifest 에서 Contact Picker 사용 선언

41. Contact Picker Code ContactPicker picker = new ContactPicker(); picker.SelectionMode = ContactSelectionMode.Contacts; // Contact contacts = await picker.PickContactAsync();// 1 개 IList contacts = await picker.PickContactsAsync();// 여러개 foreach (Contact contact in contacts) { // process each contact returned Debug.WriteLine(contact.FirstName + " " + contact.LastName); } ContactPickerUI 로 UI 를 커스텀 가능

42. Contact card Contact card workflow View Profile ContactManager From: Ben Miller

43. ContactManager Code Contact contact = new Contact(); contact.FirstName = " 주 "; contact.LastName = " 신영 "; ContactEmail email = new ContactEmail(); email.Address = “bit1010@live.com"; contact.Emails.Add(email); Rect rect = Helper.GetElementRect(sender as FrameworkElement); ContactManager.ShowContactCard(contact, rect, Windows.UI.Popups.Placement. Default);

44. Appointments  Calrendar 앱을 통한 일정 관리  이메일 및 소셜 계정의 일정 연동됨  모든 일정의 추가 / 수정 / 삭제  AppointmentManager. ShowAddAppointmentAsync(…) 를 통해 바로 원 하는 일정 ContactCard 를 호출

45. Appointments AppointmentManager. ShowAddAppointmentAsync(…)

46. Appointments Code private async void AddAppointment_Click(object sender, RoutedEventArgs e) { var appointment = new Appointment(); appointment.Subject = "Prepare for next session"; appointment.StartTime = DateTime.Now.AddMinutes(2); appointment.Duration = TimeSpan.FromHours(1); appointment.Location = "Speaker room"; appointment.Uri = new Uri("http://dev.windows.com"); appointment.Sensitivity = AppointmentSensitivity.Public; appointment.Details = "Nothing like a little procrastination!";

47. Appointments Code Rect rect = Helper.GetElementRect(sender as FrameworkElement); var id = await AppointmentManager.ShowAddAppointmentAsync( appointment, rect, Windows.UI.Popups.Placement.Above); if (!string.IsNullOrEmpty(id)) ResultDisplay.Text = "Returned appointment id " + id; else ResultDisplay.Text = "Appointment not added."; }

63. Initialize the license Use the right license provider WinRT provides the CurrentAppSimulator for testing trial mode, in-app purchases, and more without you r app being listed in the Windows Store. CurrentApp is for submission to the Windows Store. You cannot submit an app which uses CurrentAppSimulator.

64. Handle license events

65. Conditionally enable features Hide or inform? You may find that providing a UI with a warning that the feature is only enabled in the full version is a bet ter approach than simply hiding the feature. Whenever you prompt, be sure to give the user the option t o purchase right then.
