  Hi, I'm trying to upload a file via URLConnection, but i need to read/write it as a binary file without any encoding changes.

Or is there another way to quickly copy binary data from a FileInputStream to a PrintWriter? Thank you

• Bulk update & occasional insert (coredata) - Too slow

  - by Andrew

  Update: Currently looking into NSSET's minusSet links: http://stackoverflow.com/questions/1475636/comparing-two-arrays Hi guys, Could benefit from your wisdom here.. I'm using Coredata in my app, on first launch I download a data file and insert over 500 objects (each with 60 attributes) - fast, no problem. Each subsequent launch I download an updated version of the file, from which I need to update all existing objects' attributes (except maybe 5 attributes) and create new ones for items which have been added to the downloaded file. So, first launch I get 500 objects.. say a week later my file now contains 507 items.. I create two arrays, one for existing and one for downloaded. NSArray *peopleArrayDownloaded = [CoreDataHelper getObjectsFromContext:@"person" :@"person_id" :YES :managedObjectContextPeopleTemp]; NSArray *peopleArrayExisting = [CoreDataHelper getObjectsFromContext:@"person" :@"person_id" :YES :managedObjectContextPeople]; If the count of each array is equal then I just do this: NSUInteger index = 0; if ([peopleArrayExisting count] == [peopleArrayDownloaded count]) { NSLog(@"Number of people downloaded is same as the number of people existing"); for (person *existingPerson in peopleArrayExisting) { person *tempPerson = [peopleArrayDownloaded objectAtIndex:index]; // NSLog(@"Updating id: %@ with id: %@",existingPerson.person_id,tempPerson.person_id); // I have 60 attributes which I to update on each object, is there a quicker way other than overwriting existing? index++; } } else { NSLog(@"Number of people downloaded is different to number of players existing"); So now comes the slow part. I end up using this (which is tooooo slow): NSLog(@"Need people added to the league"); for (person *tempPerson in peopeArrayDownloaded) { NSPredicate *predicate = [NSPredicate predicateWithFormat:@"person_id = %@",tempPerson.person_id]; // NSLog(@"Searching for existing person, person_id: %@",existingPerson.person_id); NSArray *filteredArray = [peopleArrayExisting filteredArrayUsingPredicate:predicate]; if ([filteredArray count] == 0) { NSLog(@"Couldn't find an existing person in the downloaded file. Adding.."); person *newPerson = [NSEntityDescription insertNewObjectForEntityForName:@"person" inManagedObjectContext:managedObjectContextPeople]; Is there a way to generate a new array of index items referring to the additional items in my downloaded file? Incidentally, on my tableViews I'm using NSFetchedResultsController so updating attributes will call [cell setNeedsDisplay]; .. about 60 times per cell, not a good thing and it can crash the app. Thanks for reading :)
