nsfetchedresultscontroller

In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12

OK so I have two entities in my data model (let's say entityA and entityB), both of these entities have a to-many relationship to each other. I have setup a NSFetchedResultsController to fetch a bunch of entityA. Now I'm trying to have the section names for the tableview be the title of entityB. sectionNameKeyPath:@"entityB.title" Now this causes a problem, where by the section name returned from that relationship appears to be ({title1}) or ({title1,title2...titleN}) obviously depending on how many different entityB's are involved. This doesn't look great in a tableview and doesn't group the

Ok. This is the exact same question as here: Why is NSFetchedResultsController loading all rows when setting a fetch batch size? But the solution for his doesn't solve for mine. I have a screen that has several thousand records and is slow to load them all. I set the batch size to 30 (roughly three times the cells on the screen) and it still loops through and loads all the batches for some reason. Here is the code - (NSFetchedResultsController *)guestCardFetchedResultsController { if (guestCardFetchedResultsController != nil) { return guestCardFetchedResultsController; } // SELECT * from

I am about to go out of my mind here, in my Core Data databse I have a lot of users, i have hooked the database up to a tableviewcontroller via NSFetchedResultController, and when the view loads, I see all my users, and i can perform a push to a detail viewcontroller via storyboard segue... so far so god, my tableview contains a custom cell with an image view and 2 uitextlabels that all has their tag values assigned.. Now, when I perform the search I create a new NSFetchedResultController with a predicate, and performs the performFetch.. I then get the fetchedObjects property and it contains

Not sure if this is an issue with the way Magical Record does saves, or I'm just making an noob mistake somewhere. I'm using an NSFetchedResultController (FRC) and UITableView to display a list of entities, when the user taps "Add" a new View Controller with an editor is pushed, a new entity is created with [MyEntity MR_createEntity] . The user can add additional entities here that are added to the main entity via a relationship. When the user taps "Save" in this View Controller the context is saved using [[NSManagedObjectContext MR_contextForCurrentThread] MR_save] The

Details are in the comments. The following code: // Perform the fetch... NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } // Confirm that objects were fetched by counting them... NSLog(@"Number of Objects = %i", [[fetchedResultsController fetchedObjects] count]); // Confirm that sections exist by counting them... NSLog(@"Numbers of Sections = %i", [[fetchedResultsController sections] count]); for (id section in [fetchedResultsController sections]) { // Count number of objects in each

First of all, sorry for the too long question. I know that there are few questions here that discuss similar issues but none of these talks about NSFetchedResultsController with delegate together with update in separate thread. And none of the solutions has helped me. These are the existing questions: NSFetchedResultsController: using of NSManagedObjectContext during update brings to crash Determining which core Data attribute/property change triggered a NSFetchedResultsController update Core Data executeFetchRequest throws NSGenericException (Collection was mutated while being enumerated)

I currently have a class which has a date object in it. This date object has both time and day in it. All this information gets loaded into a UITableViewCell via a NSFetchedResultsController . I need to sort the dates into sections where each section is the date without the Time. I also need each section to be sorted in itself by time. Here is what my current _fetchedResultsController looks like: [self.managedObjectContext lock]; NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Entity" inManagedObjectContext:self
