No Network, load from local geodatabase

VIKRANTKRISHNA — Tue, 20 May 2014 19:38:21 GMT

I am struggling to build the logic for relaunching the application (or initializing) from local geodatabase layers, when app got crashed or closed for some reason with no network availability.

I will really appreciate any help with this?

Hi, my app always starts up offline if a local geodatabase exists. My local geodatabase is in the app's Documents folder and it loads local data or live data in the viewDidLoad method. Hope it helps. Regards, Shimin.

@property (nonatomic, strong) AGSGDBGeodatabase *geodatabase;

//in the viewDidLoad
NSString *gdbFilePath = [[FCNSWUtils documentsPath] stringByAppendingPathComponent:@"MyLocalDB.geodatabase"];
    if([FCNSWUtils fileExist:gdbFilePath])
    {
        [self loadLocalData];
    }
    else
    {
        [self takeOnline];//load live data.
    }

-(void)loadLocalData
{

    NSString *gdbFilePath = [[FCNSWUtils documentsPath] stringByAppendingPathComponent:@"MyLocalDB.geodatabase"];
    AGSGDBGeodatabase *gdb = [[AGSGDBGeodatabase alloc]initWithPath:gdbFilePath error:nil];
    self.geodatabase = gdb;

    ////Remove all live feature layers if any
    for (AGSLayer* lyr in self.mapView.mapLayers)
    {
        if([lyr isKindOfClass:[AGSFeatureLayer class]])
        {
            [self.mapView removeMapLayer:lyr];
        }
    }

    //Add local feature/table layers
    for (AGSFeatureTable* fTable in self.geodatabase.featureTables)
    {
        if ([fTable hasGeometry])
        {
            AGSFeatureTableLayer *ftl = [[AGSFeatureTableLayer alloc]initWithFeatureTable:fTable];
            ftl.delegate = self;

            [self.mapView addMapLayer:ftl];
        }
    }

    [self showEditsInGeodatabaseAsBadge:self.geodatabase];

}

But How about localTileLayer?, Is it possible to store AGSLocalTiledLayer in the geodatabase as well?
