5 Runtime platforms OS X Desktop Desktop Client Windows Store QT ios.net JavaSE Mobile Android Windows Phone Windows Mobile Embedded

6 ArcGIS Runtime SDK for ios & OS X Build native applications using Objective-C & Swift OS X (Mountain Lion, Mavericks, Yosemite) ios (6.x, 7.x, 8.x)

7 Before you begin Mac - OSX 10.9, (Mavericks, Yosemite) Xcode 5.x or 6.x - Apple s ios & OSX SDKs - ios Simulator - Instruments ArcGIS Runtime SDK for ios & OSX - Latest release : Version

8 SDK Resources developers.arcgis.com

9 Displaying map content Common Workflows

10 Displaying a Map UI Component : AGSMapView - Responds to gestures - Touch - Trackpad - Mouse - Keyboard - In-built Magnifier & Callout - Displays device location - Auto pan for location updates

11 A Map is composed of Layers Temporary app data - Graphics layers Operational data - Dynamic layers - Feature layers Basemap - Tiled layer

12 Sources of map data Tiled layers subclasses of AGSTiledLayer - ArcGIS Map Services (Cached), OGC WMTS, Bing, OpenStreetMap - Fetch pre-cached tiles from services and assemble on screen - Extremely fast. Good for static data. Dynamic layers - subclasses of AGSDynamicLayer - ArcGIS Map Services, ArcGIS Image Services, OGC WMS - Generate map images from service on-demand. - Good for changing data, or customizing map display Feature layers AGSFeatureLayer - ArcGIS Feature Services - Download raw features and draw natively on screen - Good for editing

13 Layer pattern 1. Construct & Connect URL to web service //Construct layer let tiledlayer = AGSTiledMapServiceLayer(URL: serviceurl) 1. Add to mapview //Add to map view self.mapview.addmaplayer(tiledlayer, withname:"world Street Map")

14 Web Maps Author on ArcGIS Online or on-premise ArcGIS Portal - Predefined list of layers - Initial map configuration - Extent, scale range, symbology etc JSON AGSWebMap - Creates appropriate layer objects when opened into mapview //Create webmap self.webmap = AGSWebMap(itemId: "b31153c71c6c429a8b24c1751a50d3ad", credential:nil) //Open into mapview self.webmap.openintomapview(self.mapview)

15 Displaying details about geographic features Popups make it easy to view - Attributes - Graphs, Charts - Attachments - Picture - Video - PDF/MS-Office attachments

16 Demo Add a map to an app

17 Types of location apps GasBuddy Reminders Map centric No map

18 Types of location apps Yelp Redfin Map as context Map centric No map

19 Companion apps, working together For various form-factors

20 Searching for content Common Workflows

21 Searching for Content ArcGIS Online Portal Search Portal / ArcGIS Online Search for Places Search for Features

22 Searching ArcGIS Org or Portal Portal ArcGIS Org Webmap Tile Layer Map Image Layer Server Online Content and Services Feature Layer Create portal Searching for content

23 Searching ArcGIS Org or Portal Set delegate Delegation Adopt protocol Searching for content

24 Delegation Delegate acts on behalf of Delegating Object Portal 1. Portal Event Eg. Portal Loaded Or Found Map etc. 4 Respond To Class Portal Delegate (AnyClass) 2. User Interaction 3. State Change - Set a delegate object - Adopt the protocol - Implement methods of the protocol Searching for content

25 Searching ArcGIS Org or Portal Create Query Parameters Predefined Queries Custom Queries Searching for content

26 Searching ArcGIS Org or Portal Execute Queries Query Results Async Callback Delegate Methods Searching for content

27 Portal Demo

28 Search Portal / ArcGIS Online Search for Places Searching for content

29 Search for Places - Geocode Service Geocoding Address to Locations - Reverse Geocoding Locations to Addresses Create locator Set delegate Searching for content

30 Search for Places Geocoding Set Parameters Execute Searching for content

31 Search for Places Delegate Methods for Results Handle Geocoding Results - Delegation pattern - Address Candidate objects - Location - Attributes - Display in Map Searching your content

32 Geocoding Demo

33 Search Portal / ArcGIS Online Search for Places Search for Features Searching for content

34 Search for Features In a single layer At a map location Query Task Identify Task Searching for content

35 Search for Features Query Task - Single layer or table - ArcGIS Map Service, Feature Service - Vector - Query for Features, ObjectIDs or just count Create a Query task Searching for content

36 Search for Features Types of Queries Attribute Query - Attributes of the layer - where, outfields etc Statistics - Count, Std Dev etc - Group By Spatial Query - Input geometry - Intersects, Within, Touches etc Temporal Query - Input time extent Order By - Attributes - Asc or Desc Related Features - Relationship query Searching for content

37 Search for Features My favorite Query Searching for content

38 Search for Features My actual Query Searching for content

39 Search for Features Identify Task - Multiple layers - ArcGIS Map Service Create Identify Task Searching for content

40 Search for Features Identify Task Parameters layerids geometry layeroption tolerance mapenvelope size spatialreference returngeometry Execute Identify Task Searching for content

41 Graphic In-memory object Features from - Feature service - Task results AGSGraphic - Geometry - Attributes - Symbol Searching your content

42 Query Task Demo

43 ArcGIS Online Portal Search Portal / ArcGIS Online Search for Places Search for Features Find featured maps Find Items/Groups Predefined/Custom queries Geocoding Query Task Identify Task Graphic Searching for content

44 Performing Analysis Common Workflows

45 Analysis on transportation networks Plan routes - AGSRouteTask - Point to Point, or multi-point - Optimize based on distance or travel time - Reorder stops for best sequence - Time windows, Barriers & Restrictions Compute service areas - AGSServiceAreaTask Find closest facilities AGSClosestFacilityTask ArcGIS Online World Route service Countries. Live & Historical Traffic data - Requires subscription. Consumes credits On-premise Route services for custom data

46 Spatial Analysis AGSGeoprocessor - Invoke geoprocessing services ArcGIS Online Spatial Analysis service - Summarize Data (Aggregate points, etc) - Analyze Patterns (Watershed, Viewshed,etc) - Use Proxmity (Density, HotSpot, Interpolate, etc) On-premise Geoprocessing services - Custom geoprocessing tools & models

47 Geometric Operations AGSGeometryEngine - Native, high performance engine - Relationship tests - Touches, Intersects, Within, Contains, Overlaps, Crosses - Set operations - Union, Difference, Intersect - Topological operations - Cut, Clip, Simplify, Densify, Buffer, ConvexHull - Measure areas and distance - Project between spatial references

48 Recap: Task Pattern 1. Construct & Connect. - URL to web service 2. Assign a delegate 3. Set up input parameters. Invoke. 4. Process results in the delegate.

49 Demo Analysis Samples

50 Reuse code between ios & Mac M-V-C architecture enables code sharing - M : Model - V : View - C : Controller Model classes & business logic can be reused - Based on Apple s Foundation framework, common to ios & Mac View and View-Controller are platform specific - Based on Apple s UIKit on ios, AppKit on Mac

51 Editing geographic data Common Workflows

52 Editing Feature Layer Feature Layer in webmap What layer is required for Editing? ArcGIS Server ArcGIS Online/Org Portal Developers Site What are possible Feature Layer sources? Spatial Features Non-Spatial Tables Related Records Time Aware What types of features can be edited? Online Offline What are available Editing modes?

53 Sketch Layer Create, Edit Geometries Interactive No Code almost! Geometry used for Feature Layer Editing

54 Sketch Layer How does it Work? 1. Create a sketch layer 2. Assign it a mutable geometry 3. Set delegate to receive touch events Secret Step 4: Reset touch delegate after Editing!

55 Sketch Layer Undo Redo Notifications Programmatic Sketching

56 Popups Display Feature Information Edit Attributes & Attachments Edit Geometry through Sketch Layer

57 Popups Web Map Feature Layer Configure Popups in webmap Create Popup from a feature Fetch Popups Get list of popups Popups Container AGSPopupsContainerViewController

58 Popups Delegate Methods Start Edit Finish Edit Done View Cancel Delete Customize Attributes Tool Bar Buttons Presentation and much more

59 Editing Editor Tracking - User & Timestamp of Create/Update Ownership Based Access Control - Limit editing depending on user Popups handle all this! Capabilities - Limit editing for all users Data Validation - Non null, Coded and Range Values etc

60 Editing Apply Edits To Server Batch Updates Attachment Manager - Coarse grained methods

61 Editing Demo

62 Offline Capabilities Common Workflows

63 Patterns for generating offline content Desktop Pattern - Package data through ArcMap - Side load onto device, or bundle in application Services Pattern - Extract data from services on-the-fly - Tile package - AGSDownloadTileCacheTask - Geodatabase - AGSGDBSyncTask Tile package Geodatabase Network Dataset Locator

64 Offline Mapping View & Interact with maps - Display Tile package - AGSLocalTileLayer - Display Geodatabase - AGSFeatureTableLayer - Query using SQL or spatial criteria - Edit existing or create new features Layer pattern remains the same 1. Construct & Connect Path to local data Tile package Geodatabase 2. Add to mapview

65 Offline Editing Edits persisted in the geodatabase on the device Changes can be synchronized with the service - Upload only, Download only, or Bidirectional Synchronize Download Author Map View Query Analyze Edit

66 Offline Analysis Find addresses - AGSLocator using Locator files Get directions - AGSRouteTask using Network dataset Task pattern remains the same 1. Construct & Connect. - Path to local data 2. Assign a delegate 3. Set up input parameters. Invoke. 4. Process results. Network Dataset Locator
