Hello,
its urgent ...
i actually tried ways , even checked ESRI sample code QueryTaskExample. i need simply to get Fields Names or Attributes of any Layer .
i used following method...
self.queryTask = [AGSQueryTask queryTaskWithURL:[NSURLURLWithString:strMAPURL]]; // here i send like @"http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/3"
self.queryTask.delegate = self;
//return all fields in query
self.query = [AGSQuery query];
self.query.outFields = [NSArray arrayWithObjects:@*, nil];
self.query.text = @Fields; // with out this line or without empty query it gives error
[self.queryTask executeWithQuery:self.query];
i access below delegates :
//results are returned
- (void)queryTask:(AGSQueryTask *)queryTask operation:(NSOperation *)op didExecuteWithFeatureSetResult:(AGSFeatureSet *)featureSet {
//get feature, and load in to table
self.featureSet = featureSet;
[super.tableView reloadData];
}
featureSet.fields // this should be giving me Name of Fields for Layer 3....
but i am getting Array as 0 elements...... i need to get Fields name in same order as there in Server Layer....
