In "downloadFiles" method there are some logic and data storage operations and for each of the discipline you can call this snippet:


	NodeHeaderDatas *nodeDatas = [mFilesToProcess objectAtIndex:0];
	NSString *nodeidForAPICall = nodeDatas.nodeID;
    
	CommunicationSingleton *CSS = [CommunicationSingleton sharedSingleton];
	NSMutableURLRequest *requestForNodeData = [[NSMutableURLRequest alloc] init];
	NSString *nodesURL;
        if (nodeDatas.disciplineForDownloading != NULL) {
            nodesURL = [NSString stringWithFormat:
                        @"%@%@/objects/%@/disciplines/%@/geometries/threejs",
                        [CSS getDefaultAPIURL],
                        [CSS getSlug],
                        nodeidForAPICall,
                        nodeDatas.disciplineForDownloading];
        }else{
            nodesURL = [NSString stringWithFormat:
                        @"%@%@/objects/%@/geometries/threejs",
                        [CSS getDefaultAPIURL],
                        [CSS getSlug],
                        nodeidForAPICall];
            
        }
        [requestForNodeData setURL:[NSURL URLWithString:nodesURL]];
        [requestForNodeData setHTTPMethod:@"GET"];
        [requestForNodeData setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        [requestForNodeData setValue:[CSS getAuthorization] forHTTPHeaderField:@"Authorization"];

        
        if(requestForNodeData){
            mConnection = [[NSURLConnection alloc] initWithRequest:requestForNodeData delegate:self startImmediately:YES];
        }
if (!mConnection)
        {
            // Connection Failed
        }
        else
        {
            [mConnection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
            [mConnection start];
        }
        [requestForNodeData release];
