POAnimate data refresh (soft delete) on Core Data / UITableView
text
Body
copied!<p>I have a table view that's backed by a fetchedResultsController. On my table cells I have a button that performs a soft delete, as far as the view is concerned... tap the button, the selector that performs the soft delete is called, and ... something is supposed to happen (I've tried a lot of things), but nothing I've tried animates like Apple's row animations.</p> <p>I can perform simple row animations, like making it slide out of the way (which leaves a blank row until I tell the table to reload, which in turn is a bit of a jarring effect). This is the closest I've come:</p> <pre> -(void) completeTask: (id) sender { NSIndexPath *indexPath = [self.tableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]]; NSDate *date = [[NSDate alloc] init]; NSManagedObject *task = [self.fetchedResultsController objectAtIndexPath:indexPath]; [task setValue:date forKey:@"complete"]; AppController *ac = [AppController sharedAppController]; NSManagedObjectContext *moc = [ac managedObjectContext]; NSError *error = nil; if(![moc save:&error]){ NSLog(@"%@ %@",error, [error description]); exit(-1); } else { UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath]; CGRect cellFrame = cell.frame; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.35]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(someAnimationDidStop:finished:context:)]; cell.frame = CGRectMake(cellFrame.size.width , cellFrame.origin.y, cellFrame.size.width, cellFrame.size.height); [UIView commitAnimations]; } } -(void) someAnimationDidStop:(NSString *)animationID finished:(BOOL)finished context:(void *)duration { NSLog(@"Animation Stopped"); [self fetchResults]; // this guy performs a new fetch and table data reload } </pre> <p>I feel like I'm sort of on the right track, however I don't think this is really quite the answer. I was hoping that somehow <code>controller:didChangeObject:atIndexPath:forChangeType:newIndexPath:</code> would be the answer. My guess is that if I want the stock Apple animations, I will have to create a separate NSMutableArray to track the results and just make sure it's kept in sync.</p> <p>Thoughts and opinions? </p> <p>Thanks!!!</p>
