8. MonkeySpace ConfApp github.com/chrisntr/MonkeySpace iOS 6 version up on GitHub

9. What’s new for developers?

10. What’s new for developers? • Social • UIKit Improvements •

    Maps • Reminders • UICollectionView • PassKit

11. No more Snow Leopard NO

12. No more Snow Leopard • Xcode 4.5/ iOS 6.0 works

    on Lion and Mountain Lion, requires MonoTouch 6.0 • Xcode 4.5 removes support for ARMv6 devices • Xcode 4.4 / iOS 5.1.1 works on Snow Leopard, Lion and Mountain Lion with MonoTouch 5.4 and can build for ARMv6 devices • ARMv6 devices = iPhone (1st Generation), iPhone 3G, iPod Touch (1st and 2nd Generation) • Download Xcode 4.4 and install in /Applications/Xcode44.app and change location in MonoDevelop’s ‘SDK Locations’

13. Good news for developers http://tcrn.ch/RQbjVY iOS 5.1.1 = iOS 6.0

    =

14. Handling the iPhone 5 MonoDevelop 3.0.5 adds support Add a

    [email protected] named image

15. Handling the iPhone 5 Referencing “Default.png” splashView = new UIImageView(new

    RectangleF(0f, 0f, 320f, 480f)); splashView.Image = UIImage.FromFile("Default.png");

16. Handling the iPhone 5 Referencing “Default.png” splashView = new UIImageView(new

    RectangleF(0f, 0f, 320f, 480f)); splashView.Image = UIImage.FromFile("Default.png"); splashView = new UIImageView(UIScreen.MainScreen.Bounds); if (UIScreen.MainScreen.Bounds.Height > 480f) splashView.Image = UIImage.FromFile("[email protected]"); else splashView.Image = UIImage.FromFile("Default.png"); Becomes

18. Social Framework Twitter in iOS 5

19. Social Framework Twitter in iOS 5 var tweet = new

    TWTweetComposeViewController(); tweet.SetInitialText ("I'm in '" + DisplaySession.Title + "' at #monkeyspace" ); PresentModalViewController(tweet, true); if (TWTweetComposeViewController.CanSendTweet) { // Do Tweet option displaying here } Check for Twitter access

20. Social Framework Twitter, Facebook and SinaWeibo in iOS 6 if

    (UIDevice.CurrentDevice.CheckSystemVersion(6,0) && SLComposeViewController.IsAvailable(SLServiceKind.Facebook)) { // Do Facebook option displaying here } var facebook = SLComposeViewController.FromService(SLServiceKind.Facebook); facebook.SetInitialText("I'm in '" + DisplaySession.Title + "' at #monkeyspace" ); PresentViewController(facebook, true, null);

21. Social Framework Twitter, Facebook and Weibo in iOS 6

22. MonkeySpace 2012 Demo

23. Social Framework UIActivityViewController from UIKit var message = "I'm in

    '" + DisplaySession.Title + "' at #monkeyspace"; var social = new UIActivityViewController(new NSObject[] { new NSString(message) }, new UIActivity[] { new UIActivity() }); PresentViewController(social, true, null); • Provide multiple objects - Strings, Images, Custom data that implement UIActivityItemSource • Include types of Activities you want to share with, can exclude activities such as PostToFacebook or E-mail

24. Social Framework UIActivityViewController all the social networks

25. MonkeySpace 2012 Demo

26. UIKit Improvements Pull To Refresh - Side by Side comparison

27. UIKit Improvements UIRefreshControl • Implement ValueChanged event • Handle Being/EndRefreshing

    • Optional Title and TintColor NavigationItem.SetRightBarButtonItem (new UIBarButtonItem (UIBarButtonSystemItem.Refresh), false); NavigationItem.RightBarButtonItem.Clicked += (sender, e) => { Refresh(); }; Becomes if (UIDevice.CurrentDevice.CheckSystemVersion (6,0)) { // Display UIRefreshControl here } else if { NavigationItem.SetRightBarButtonItem (new UIBarButton.... NavigationItem.RightBarButtonItem.Clicked += (sender, e) => ... }

28. UIKit Improvements UIRefreshControl RefreshControl = new UIRefreshControl(); RefreshControl.ValueChanged += HandleValueChanged;

    AppDelegate.Conference.OnDownloadSucceeded += (jsonString) => { Console.WriteLine ("OnDownloadSucceeded"); InvokeOnMainThread (() => { RefreshControl.EndRefreshing (); }); }; AppDelegate.Conference.OnDownloadFailed += (err) => { Console.WriteLine ("OnDownloadFailed"); InvokeOnMainThread (() => { RefreshControl.EndRefreshing (); }); };

30. Maps

31. Maps

32. Maps • New Class - MKMapItem • Maps app in

    the simulator • Can send MKMapItems to the Maps app • Can receive MKMapItem data from

33. Maps Sending data to the Maps app if(UIDevice.CurrentDevice.CheckSystemVersion(6,0)) segmentedControl.InsertSegment ("Directions",

    3, false); var conferenceMapItem = new MKMapItem(new MKPlacemark(ConferenceLocation, null)); conferenceMapItem.Name = "MonkeySpace"; var conferenceHotel = new MKMapItem(new MKPlacemark(new CLLocationCoordinate2D(42.36346, -71.0863), null)); conferenceHotel.Name = "MonkeySpace Hotel"; var mapItems = new MKMapItem[] { conferenceMapItem, conferenceHotel }; MKMapItem.OpenMaps(mapItems, new MKLaunchOptions() { DirectionsMode = MKDirectionsMode.Walking });

34. MonkeySpace 2012 Demo

35. Maps Receiving data from the Maps app 1. Create a

    GeoJson file with “.geojson” extension { "type": "MultiPolygon", "coordinates": [ [[[-122.7, 37.3], [-121.9, 37.3], [-121.9, 37.9], [-122.7, 37.9], [-122.7, 37.3]]], [[[-87.9, 41.5], [-87.3, 41.5], [-87.3, 42.1], [-87.9, 42.1], [-87.9, 41.5]]] ] }

36. Maps Receiving data from the Maps app 2. Set the

    Maps options in the plist file (MonoDevelop 3.0.5+)

37. Maps Receiving data from the Maps app 3. Override OpenUrl

    on AppDelegate and check for Url if (MKDirectionsRequest.IsDirectionsRequestUrl (url)) { var request = new MKDirectionsRequest(url); // Do something with the request }

38. MonkeySpace 2012 Demo

39. Reminders App.Current.EventStore.RequestAccess (EKEntityType.Reminder, (bool granted, NSError e) => { if

    (granted) { // Create a EKReminder and save reminder } else { new UIAlertView ( "Access Denied", "No Access", null, "OK", null).Show (); } ); • EKReminder is part of EventKit, subclasses EKCalendarItem • Need to request access to Reminders for Read/Write • Fetch, Save, Delete Reminders and with Predicates for searching Add a reminder for session

40. Reminders Add a reminder for session EKReminder reminder = EKReminder.Create

    (App.Current.EventStore); reminder.Title = DisplaySession.Title; reminder.Calendar = App.Current.EventStore.DefaultCalendarForNewReminders; reminder.Notes = DisplaySession.Abstract; var date = new NSDateComponents(); date.Day = DisplaySession.Start.Day; date.Month = DisplaySession.Start.Month; date.Year = DisplaySession.Start.Year; date.Hour = DisplaySession.Start.Hour; date.Minute = DisplaySession.Start.Minute; date.Second = DisplaySession.Start.Second; reminder.StartDateComponents = date; reminder.DueDateComponents = date; App.Current.EventStore.SaveReminder (reminder, true, out e);

42. UICollectionView View Bing images uploaded with the name “monkeyspace” •

    UITableView for a collection of items • Handles layout automatically, can be customized with UICollectionViewFlowLayout

43. UICollectionView View Bing images uploaded with the name “monkeyspace” •

    Override ViewDidLoad to handle registering classes • Override GetItemCount • Override GetCell • Can override ItemSelected, ItemDeselected, ItemHighlighted, ItemUnhighlighted • Can override GetViewForSupplementaryElement to display a “Header” or “Section” view.

47. PassKit An overview

48. PassKit Check availability of the PKPassLibrary if (PKPassLibrary.IsAvailable) { //

    Display PassKit views } library = new PKPassLibrary (); noteCenter = NSNotificationCenter.DefaultCenter.AddObserver (PKPassLibrary.DidChangeNotification, (not) => { BeginInvokeOnMainThread (() => { // refresh the pass passes = library.GetPasses (); RenderPass(passes); }); }, library); passes = library.GetPasses (); RenderPass(passes); Get the passes for the application
