Upside - down chat

[lubomirez]

Firstly thx for this great control. If someone wants to have chat sorted newest on top, change reload data in UIBubbleTableView.m to:

- (void)reloadData
{
    self.showsVerticalScrollIndicator = NO;
    self.showsHorizontalScrollIndicator = NO;

    // Cleaning up
    self.bubbleSection = nil;

    // Loading new data
    int count = 0;
#if !__has_feature(objc_arc)
    self.bubbleSection = [[[NSMutableArray alloc] init] autorelease];
#else
    self.bubbleSection = [[NSMutableArray alloc] init];
#endif

    if (self.bubbleDataSource && (count = [self.bubbleDataSource rowsForBubbleTable:self]) > 0)
    {
#if !__has_feature(objc_arc)
        NSMutableArray *bubbleData = [[[NSMutableArray alloc] initWithCapacity:count] autorelease];
#else
        NSMutableArray *bubbleData = [[NSMutableArray alloc] initWithCapacity:count];
#endif

        for (int i = 0; i < count; i++)
        {
            NSObject *object = [self.bubbleDataSource bubbleTableView:self dataForRow:i];
            assert([object isKindOfClass:[NSBubbleData class]]);
            [bubbleData addObject:object];
        }

        [bubbleData sortUsingComparator:^NSComparisonResult(id obj2, id obj1)
         {
             NSBubbleData *bubbleData1 = (NSBubbleData *)obj1;
             NSBubbleData *bubbleData2 = (NSBubbleData *)obj2;

             return [bubbleData1.date compare:bubbleData2.date];            
         }];

        NSDate *last = [NSDate dateWithTimeIntervalSince1970:0];
        NSMutableArray *currentSection = nil;

        for (int i = 0; i < count; i++)
        {
            NSBubbleData *data = (NSBubbleData *)[bubbleData objectAtIndex:i];

            if (([last timeIntervalSinceDate:data.date] > self.snapInterval) || (i==0))
            {
#if !__has_feature(objc_arc)
                currentSection = [[[NSMutableArray alloc] init] autorelease];
#else
                currentSection = [[NSMutableArray alloc] init];
#endif
                [self.bubbleSection addObject:currentSection];
            }

            [currentSection addObject:data];
            last = data.date;
        }
    }

    [super reloadData];
}

If you want, add it as option ;)
