Unable to read AGSGDBGeodatabase

MuzammilAK — Mon, 21 Apr 2014 07:53:39 GMT

Dear All,

I'm developing a small application (with Runtime SDK for iOS 10.2.2) for displaying an offline geodatabase (.geodatabase file) that I have created with ArcGIS for Desktop 10.2.1.

The application crashes at below line in debug mode. In Device mode, the gdb value is nil ( I used iTunes File Sharing for device).
AGSGDBGeodatabase *gdb = [[AGSGDBGeodatabase alloc] initWithPath:thePathString error:&error];

Exception Details in Console Window:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'This AGSFeatureTable is backed by a non-spatial table. A spatial table is required to be rendered in a layer.'

Looks like there is a problem with .geodatabase file. I tried a sample with 1 simple layer. It works.
But when i generate .geodatabase file with many layers, I get above exception.

Regards
Muzammil

Hello Muzammil,

I am wondering do you have any standalone tables in your Feature Service? Or any one of your layers is based on a Join?

Create a bundle for the geodatabase file the problem is with getting the full path for the geodatabsae file
This happen with me last week

Hello Muzammil,

I used this snippet code and successfully load a local geodatabase with several layers. You can take a try.

[PHP]AGSGDBGeodatabase *gdb = [[AGSGDBGeodatabase alloc] initWithPath:gdbPath error:&error];
    for (AGSFeatureTable* fTable in gdb.featureTables) {
        if ([fTable hasGeometry]) {
            [self.mapView addMapLayer:[[AGSFeatureTableLayer alloc]initWithFeatureTable:fTable]];
        }
[/PHP]

I am using the following swift code to load a database which is more than 20 MB in size. This code works perfectly on simulator, but not on the iPad. A smaller sized database (<5MB) could be loaded on the device.

var gdb = AGSGDBGeodatabase();

do{

print(gdbPath)

//try localGDB = AGSGDBGeodatabase(path: gdbPath)

try gdb = AGSGDBGeodatabase.init(path: gdbPath)

//Add layers from local database

for featureTable in gdb.featureTables() as! [AGSFeatureTable] {

if featureTable.hasGeometry() {

self.mapView.addMapLayer(AGSFeatureTableLayer(featureTable: featureTable))

}

}catch let error1 as NSError{

print("Error is - \(error1)")

}

How are you creating gdbPath? If it is the documents path keep in mind that this is unique for each session on the device. The app runs under a different instance ID each time so you should get the path to the documents directory using something like this:

NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as! NSString
