This page contains links to the coordinate systems supported on mobile devices. I can see that WGS 84 UTM 12 N is supported (search for 32612). So that should work. Can you provide a code snippet that fails so that we can investigate? I also see that NAD_1983_HARN_StatePlane_Montana_FIPS_2500 is supported, but it has a WKID of 2818 (not 103200 as you reported) ... View more

I suspect what is happening is that the display pipeline is not able to keep pace with the constantly changing map rotation, especially because the iPad 3 retina display requires a lot of fine detail in the graphics. As a workaround, can you try disabling the renderNativeResolution property on all the graphics layers and see if that makes things better? I have a feeling it might because the graphics layer will not try to draw in such great detail. You may see a slight degradation in the crispness of your graphics, but it may not be noticeable. Please let us know. And thank you for reporting this,  your feedback is very helpful. ... View more

What you can do is - First, project your point into the "buffer spatial reference". Next, buffer this point Finally, re-project the result back to the original spatial reference. You can do this all locally using the geometry engine. ... View more

You need to cast the object returned by [AGSMapView addMapLayer] to AGSTiledLayerView.         AGSTiledLayerView* tiledLyrView = (AGSTiledLayerView*) lyrView;         tiledLyrView.enableTileAnimation = NO; However, this will turn off all animation  and may compromise UX in other situations (such as panning). Can you upload a small video capture on YouTube displaying the problem you're seeing? We'd like to understand it more so that we may investigate better ways to improve the UX. Thanks ... View more

The license agreement does not allow storing of ArcGIS Online basemap tiles. http://downloads2.esri.com/ArcGISOnline/docs/E800_summary.pdf You can find more information about the licensing terms under the Access and Use Constraints section of each ArcGIS Online basemap item. For example - http://www.arcgis.com/home/item.html?id=10df2279f9684e4a9f6a7f08febac2a9 ... View more

Actually, we put in an enhancement at v2.1 of the SDK to prevent the map from panning outside the map's maxEnvelope property. By default, this is set to the full envelope of the basemap layer. So, if you're using v2.1 or higher, you shouldn't have to do anything really. Can you check the maxEnvelope property of your map and ensure it is appropriate? ... View more

Are you sure that the graphic you're getting back in the didClickCalloutAccessoryButtonForGraphic: parameter has any related records? For example, if you have multiple layers in your map, the graphic could belong to a completely different layer. Just to rule out such problems, I would try running the query by hardcoding the objectid (instead of getting it from the graphic's attributes). If things still don't work, we can troubleshoot more. ... View more

Unfortunately, this is not possible at this time. Could you please elaborate on the security policy you're referring to. The API already supports ArcGIS Server security model (Basic/Digest/Token). If we have more information about your needs we can try and suggest ways to meet them or build provisions in the API for a future release. ... View more

Its probably because the spatial reference of the geocoded address does not match the bing map's spatial reference. To fix this, you can provide the map's spatial reference as an input parameter to the locationsForAddress:returnFields:outSpatialReference: method. Be sure to the let the map load before you try to read its spatial reference, otherwise it will be nil. ... View more

You have 2 calls to normalizeCentralMeridian, once when you instantiate a blank polyline, and the other after you have already assigned the polyline to a graphic. Both of these will have no affect. The first call does nothing because the polyline is empty. The second does infact normalize and return a new polyline, but your graphic is already set up with the original un-normalized polyline. You need to call normalize after you add the last vertex to the polyline, and before you assign the polyline to the graphic. ... View more

One reason why you may be experiencing the problem you describe is because you may be allocating the query task again and again in the loop.  The following line of code - self.queryTask = [AGSQueryTask queryTaskWithURL:[NSURL URLWithString:waterLayerURL]]; will release the previous instance of query task and create a new one. When the previous one is released, it will no longer invoke the delegate. (for more information, refer to apple's doc on objective-C properties) If all your queries are against the same service, you should create the task only once, and call executeWithQuery: in a loop for each query. ...

You will need to project your polygon to an Equal Area Projected Coordinate System, such as Cylindrical Equal Area (WKID : 53034). This coordinate system uses Meters as the unit and will preserve the area of the original geometry. Thus, you will need to use the Geometry Engine to first project, and then compute area. PS: I noticed that your polygon is not topologically complete. You need to close the ring by adding P1 vertex also at the end. ... View more

The AGSGeometryEngine class has a similar method. For more information about wrap-around, refer to http://help.arcgis.com/en/arcgismobile/10.0/apis/iOS/2.0/concepts/index.html#/Enabling_Wrap_Around/00pw00000050000000/ ... View more

The offline editing sample uses the offline tiled layer to ensure that the tiles can still be seen when the device is offline. The offline tiled layer is provided as an independent sample of a custom tiled layer. See this for more information. ... View more
