5 ArcGIS for Web & Mobile Web APIs Flex JavaScript Silverlight REST Runtime SDKs ArcGIS Server

6 Native Applications and Runtime SDKs Configurable COTS applications and Native ArcGIS Runtime SDKs ios Android Windows Phone Windows Mobile Windows Linux Applications Applications Applications Applications Applications Applications ArcGIS ArcGIS ArcGIS ArcGIS ArcGIS Explorer* None Runtime SDK Runtime SDK Runtime SDK Runtime SDK Runtime SDK Runtime SDK Objective C Java Silverlight.NET WPF, Java Qt, Java

7 ArcGIS Runtime SDK for ios Formerly known as ArcGIS API for ios

8 ArcGIS Runtime SDK for ios Build native applications using Objective-C - iphone 3GS / 4 / 4S, ipod Touch, ipad 1 / 2 - Must be running ios 4 or higher

9 Web or Native applications? ESRI supports both Advantages of native applications - Tighter integration with other native apps - Access to resources - Contacts, calendar events, photos - Marketing/Hosting/Reporting via AppStore Disadvantages - Dedicated effort to write and maintain

10 Before you can begin.. You need an Intel-based Mac running OSX 10.6 (Snow Leopard) or 10.7 (Lion) Join ios Developer Program - Standard : AppStore distribution - Enterprise : In-House distribution Download ios SDK (4.2.x) & Xcode IDE (4.x)

11 Before you can begin.. ArcGIS Runtime SDK for ios - v2.2 : Download from the Resource Center Conceptual Help API Reference Developer Samples Deployment User Forum

12 Developing Applications

13 What you can do with the API Display maps Perform analysis Visualize results Collect data Access Online content - Using ArcGIS Portal REST API - New at v2.2

14 Built using the SDK

15 DEMO

16 Displaying a Map UI Component AGSMapView - Responds to gestures - Displays device location, heading, and bearing - Wrap-around dateline

17 Displaying a Map Add AGSMapView to the UI using Interface Builder Or, programmatically through code

18 Adding Content to AGSMapView Mashup basemap & operational layers - ArcGIS Server, WMS - Bing, Open Street Map - Graphics - Local Tile Packages //create the layer AGSLocalTiledLayer* mylayer = [AGSLocalTiledLayer localtiledlayerwithname:@"wildlifehabitat"]; //add to map [self.mapview addmaplayer:mylayer withname:@ MyLayer1"];

19 Adding Content to AGSMapView Open web maps - ArcGIS.com - Portal for ArcGIS //create the web map AGSWebMap* webmap = [AGSWebMap webmap withitemid:@"e229d715f7ca4fa fb288165" credential:nil]; //open into mapview [webmap openintomapview:self.mapview];

20 Respond to events through Delegates Map Delegates Layer Events - Map loaded, failed to load - Layer loaded, failed to load Touch Events - Tap, Tap and Hold - Move Tap and Hold Callout Events - Did Show Callout, Should Show Callout - Did Click Accessory Button

21 Responding to Map Touch events 1. Adopt the Delegate MyController: UIViewController <AGSMapViewTouchDelegate> { } 2. Implement the protocol MyController - (void) mapview:(agsmapview*) mapview didclickatpoint:(cgpoint) screen mappoint:(agspoint*) mappoint graphics:(nsdictionary*) graphics { //handle touch event } 3. Set Delegate self.mapview.touchdelegate = self;

22 DEMO Displaying a map

23 Performing Analysis Using Tasks Query, Find, Identify Task - Search for features In the map Geoprocessing Task - Spatial analysis using GP tools and models Locator - Geocode and reverse geocode addresses

24 Performing Analysis Using Tasks (Contd.) Geometry Engine - native, high performance engine for performing geometric operations on the device Network Analysis - Point-to-point and multipoint routes - Service Areas based on drive times - Closest facility for an incident

25 Common Pattern for using Tasks 1. Adopt the Task Delegate MyController: UIViewController <AGSLocatorDelegate> { } 2. Implement the protocol methods - (void)locator:(agslocator*)locator operation:(nsoperation*)op didfindlocationsforaddress:(nsarray*)candidates { //todo } - (void)locator:(agslocator*)locator operation:(nsoperation*)op didfaillocationsforaddress:(nserror*)error { //todo }

26 Common Pattern for using Tasks 3. Instantiate the task self.locator = [AGSLocator locatorwithurl:[nsurl URLWithString:kGeoLocatorURL]]; 4. Set Delegate self.locator.delegate = self; 5. Perform operation NSOperation* op = [self.locator locationsforaddress:addresses returnfields:outfields];

27 Visualizing Results Graphics Layer - Collection of Graphics Graphic = Geometry + Symbol Polyline Line Point Polygon Marker Picture Fill Text Composite

28 Visualizing Results Contd. Graphic can optionally contain - Attributes - Information about the graphic - Info Template - Which attributes to display in a Callout

29 Visualizing Results Contd. //create the symbol AGSPictureMarkerSymbol *marker = [AGSPictureMarkerSymbol picturemarkersymbolwithimagenamed:@"bluepushpin.png"]; //create the graphic AGSGraphic *graphic = [AGSGraphic graphicwithgeometry:point symbol:marker attributes:dictionary //add the graphic to the graphics layer [self.graphicslayer addgraphic:graphic];

30 Visualizing Results Contd. Callout - Displayed when user taps on a graphic Content - Title & Detail - Image - Accessory button - Custom UI View

31 Specifying Content for the Callout 1. Adopt the Delegate MyController: UIViewController <AGSInfoTemplateDelegate> { } 2. Implement the protocol MyController - (NSString *) titleforgraphic:(agsgraphic*)graphic screenpoint:(cgpoint)screen mappoint:(agspoint*)map { //todo } - (NSString *) detailforgraphic:(agsgraphic*)graphic screenpoint:(cgpoint)screen mappoint:(agspoint*)map { //todo } 3. Set the delegate on the graphic AGSGraphic *graphic =... graphic.infotemplatedelegate = self;

32 Responding to the Callout s Accessory button 1. Adopt the Delegate MyController: UIViewController <AGSMapViewCalloutDelegate> { } 2. Implement the protocol MyController - (void) mapview:(agsmapview*) mapview didclickcalloutaccessorybuttonforgraphic:(agsgraphic*) graphic { //todo } 3. Set the delegate self.mapview.calloutdelegate = self;
