Try this:

// _group, _queue are iVar variable
dispatch_group_t *_group = dispatch_group_create();
dispatch_queue_t *_queue = dispatch_queue_create("com.company.myqueue2", NULL);

// all files download
for(int i = 0 ; i < numberOfFileDownloads; i++){
   dispatch_group_async(_group, _queue, ^{
      // here is background thread;
      // download file
   });
}


// all files are download successfully, this method is called
dispatch_group_notify(_group, _queue, ^{
}
