What is a mapping app? ArcView right?
Attribution: Will Click
Desktop to Mobile
iPad form
Map centric apps
Map first What map do you open and how does it look? What tools?
Attribution: Will Click
How present those tools? Toolbar? Default active tools?
Map-less apps
Tasks run in background
Use should never know
Threading; don’t interrupt their flow
Objective-C Best practices

The Dark Age of Objective-c
•
Before iOS development Objective-C didn’t progress
•
iOS pushed Apple to improve the language closer to C#
•
The low-level nature of Objective-C turned into an advantage again and it might at least partly be responsible for the generally better performance of iOS compared to its competitors
Automatic Reference Counting
•
ARC is your friend
ARC Gotchas
•
Dead by ARC is a common mistake
•
Loops and forcing ARC to release.
•
Let the compiler do the releasing for you.
Manage memory in Arc
• •
Let’s create a new project …
Let’s migrate an existing project …
Use the latest xCode 4.6.1
•
Settings upgrade
@property and @synthesize
•
Objective-C may change at every xCode release.
•
Accept the project changes
NSLog vs DebugLog
•
#if DEBUG
•
# define DBLog(fmt,...) NSLog(@"%@",[NSString stringWithFormat:(fmt), ##__VA_ARGS__]);
•
#else
•
# define DBLog(...)
•
#endif
ArcGIS Runtime SDK for iOS Ninja Tricks

Projection and Reporjection
•
The world is 102100 (Web Mercator Auxiliar Sphere
•
Consume everything in 102100 or repoject graphics
•
// Spatial Reference you want to project to
•
AGSSpatialReference *sr = [AGSSpatialReference spatialReferenceWithWKID:4326];
•
AGSGeometry *newGeometry = [geometryEngine projectGeometry:oldGeometry toSpatialReference:sr];
Geometry Engine
•
Modifying Geometry Objects based on Topological Relationships -
Cuts, Clips, Buffer, etc …
•
Measuring Distance
•
Spatial Relationships -
Contains
-
Crosses
-
Intersects
-
Etc …
Number of Layers
•
More layers more time. Questions?
•
Let’s move on…..
JSON is your friend
•
// from json to object
•
NSString* jsonPointAsString = @"{ \"x\" : -118.4 , \"y\" : 45.2 , \"spatialReference\" : {\"wkid\" : 4326} }";
•
NSDictionary *json = [jsonPointAsString AGSJSONValue];
•
AGSPoint* point = [[AGSPoint alloc] initWithJSON:json];
•
// from object to json
•
json = [point encodeToJSON];
•
jsonPointAsString = [json AGSJSONRepresentation];
Graphics Layer Performance
•
Version 10.1.1 Update 1 instead of 10.1.1
•
Improves graphics layer performance.
AGSGraphic
•
AGSGraphic needs 3 things: -
Geometry
-
Symbol -
-
Simple, Ramps, Time based symbols, etc …
Attributes
Use WebMaps!
•
Multiple layers
•
Make changes without code changes.
•
Control Security.
•
NSURL* endpoint = [NSURL URLWithString:@"http://<my_arcgis_portal>/sharing"];
•
AGSWebMap* webmap = [[AGSWebMap alloc] initWithItemId:@"e229d715f7ca4fa980308549fb288165" sharingEndPoint:endpoint credential:credential];
Sketch Layer as user input!
• Build in user input • Allows the user to interact with: • Vertex • Mid point between vertices • Selected vertex • Area enclosed by the vertices • Line joining the vertices
Go Beyond …

CocoaControls
•
Existing OS controls for iOS
•
Cocoacontrols.com
GitHub
•
Social Coding, share and fork
Whats coming in Runtime 10.2 and beyond
Whats coming for Runtime…
•
10.2 -
•
Offline map use -
Being productive offline
-
Network/geocode/search
-
Performance (static/dynamic mode)
-
Security (OAuth, SAML)
-
Simplification of apis
-
New developer site (with better doc system)
Beyond -
Offline analysis
-
Local data support -
