cant display messages based on date of the data.

[iTroyd23]

if we set snap interval, messages display based snapinterval. how to list out the message based on the data's date

update: replace the below method in uibubbletableview:

• (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 obj1, id obj2)
  {
     NSBubbleData *bubbleData1 = (NSBubbleData *)obj1;
     NSBubbleData *bubbleData2 = (NSBubbleData *)obj2;
  
     return [bubbleData1.date compare:bubbleData2.date];            
  }];
  
  NSMutableArray *currentSection = nil;
  NSMutableArray * datesArray = [[NSMutableArray alloc]init];
  
  for (int i = 0; i < count; i++)
  {
    NSBubbleData *data = (NSBubbleData *)[bubbleData objectAtIndex:i];
  
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];
    [dateFormat setDateFormat:@"MMMM d, yyyy"];
    NSString* timeString =[dateFormat stringFromDate:data.date];
  
    if(![datesArray containsObject:timeString])
    {
        [datesArray addObject:timeString];
    }
  
  }
  
  for (int j = 0; j <[datesArray count]; j++)
  {
    currentSection = [[NSMutableArray alloc] init];
  
        for (int i = 0; i < count; i++)
        {
             NSBubbleData *data = (NSBubbleData *)[bubbleData objectAtIndex:i];
            NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
            [dateFormat setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];
            [dateFormat setDateFormat:@"MMMM d, yyyy"];
            NSString* timeString =[dateFormat stringFromDate:data.date];
  
                if ([timeString isEqualToString:[datesArray objectAtIndex:j]])
                {
             [currentSection addObject:data];
                }
        }
     [self.bubbleSection addObject:currentSection];
  }

  }

  [super reloadData]; }
