Offline Inspections Sample - Shown at the User Conference 2011 Plenary Demo

This sample demonstrates how you can build a complete, custom application that allows users to collect features when the device does not have network connectivity, and then synchronize those changes when connectivity is restored.

The Inspections application works in both connected and disconnected environments. Both environments allow the user to perform inspections on features within a user-defined inspection layer. The user will download the feature data while connected and can then bring the application into an offline mode. The application will populate an inspection form with any related data from the feature being inspected. The application persists any collected data until the user regains network connectivity and can post the inspections to their server.

The sample uses a local tiled layer to display map contents of a tile package (Imagery.tpk) included within the application bundle. Tile package is a new format available from ArcGIS 10.1 onwards.

offline-data-collection-ios's Issues

Code halted at autoreleasepool

I have a strange issue with a version of this code that I've only modified in minor ways. The inspections run fine using a feature class identical to the tank data (http://test.maps.kytc.ky.gov/ArcGIS/rest/services/Pavement_iOSTestO/FeatureServer/0). However, I get a crash when I modify the feature class to include fields required in my app (http://test.maps.kytc.ky.gov/ArcGIS/rest/services/Condition_Survery_P/FeatureServer/0). The crash is odd as there is no error message. The IDE just halts on the line below. Stepping over this just crashes the app. All of the variables seem okay. I assume it has to do with one of the attribute fields being required, but I am unsure which. I plan to add all the attributes from tanks and remove them one at a time to see if that solves it. Any ideas what might be happening?

int retVal = UIApplicationMain(argc, argv, nil, nil); (from int main in main.m)

Compile Issue

I tried to compile a fresh copy of this code and it won't compile. I think it is related to the ESRI runtimes. Any idea what version this app was built for? I have the original code from ESRI's plenary demo and it compiles fine with the latest runtimes.
