UITableViewCell is choppy when scrolled for Custom Table View Cell - ios

Question

I have a tableview that contains 3 different types of uitableview cell. And it is choppy when i scrolled down or up. I have tried many ways to not make it choppy but fail.
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.rowHeight = UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight = 44;
self.tableView.estimatedSectionHeaderHeight = 0;
self.tableView.estimatedSectionFooterHeight = 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell;
CD_Dates *dates = [self.cdMenuStream.dates objectAtIndex:indexPath.section];
MenuTableViewCell *tCell = [self.tableView dequeueReusableCellWithIdentifier:#"MenuTableViewCell" forIndexPath:indexPath];
switch ([self getRowTypeForIndexPath:indexPath]) {
case RowTypeMenu:
[tCell configMenuCell:dates.menu withAnimation:self.switchMenuAnimationFlag];
break;
case RowTypeAddon:
[tCell configAddonCell:dates.addon_menu withAnimation:self.switchMenuAnimationFlag];
break;
case RowTypeContent:
[tCell configContentCell:dates.content];
break;
default:
break;
}
tCell.delegate = self;
tCell.currentIndexPath = indexPath;
if (indexPath.section == 0 && indexPath.row == 0) {
tCell.csMarginTopTitleView.constant = 0;
}
[tCell setNeedsDisplay];
[tCell layoutIfNeeded];
cell.layer.shouldRasterize = YES;
cell.layer.rasterizationScale = [UIScreen mainScreen].scale;
cell = tCell;
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
CGFloat heightRow = 0;
switch ([self getRowTypeForIndexPath:indexPath]) {
case RowTypeMenu:
heightRow = 477.6667;
break;
case RowTypeAddon:
heightRow = 283.6667;
break;
case RowTypeContent:
heightRow = 187.6667;
break;
default:
break;
}
if (heightRow == 0) {
return UITableViewAutomaticDimension;
}
if (indexPath.section == 0 && indexPath.row == 0) {
heightRow = heightRow - 22.5;
}
return heightRow;
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(MenuTableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat horizontalOffset = -17.5;
NSString *key = [NSString stringWithFormat:#"%zd %zd", indexPath.section, indexPath.row];
if ([self.contentOffsetDictionary valueForKey:key]) {
horizontalOffset = [self.contentOffsetDictionary[key] floatValue];
}
[cell setNeedsDisplay];
[cell.collectionView setContentOffset:CGPointMake(horizontalOffset, cell.collectionView.contentOffset.y)];
[cell layoutIfNeeded];
}
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat heightRow = 0;
switch ([self getRowTypeForIndexPath:indexPath]) {
case RowTypeMenu:
heightRow = 477.6667;
break;
case RowTypeAddon:
heightRow = 283.6667;
break;
case RowTypeContent:
heightRow = 187.6667;
break;
default:
break;
}
if (heightRow == 0) {
return UITableViewAutomaticDimension;
}
if (indexPath.section == 0 && indexPath.row == 0) {
heightRow = heightRow - 22.5;
}
return heightRow;
}
It is a tableview wrapped with a custom tableview cell, and that each custom tableview cell has a collection view. It is not choppy if i scroll the collection view in the custom tableview cell, but it is when i scroll the tableview. Is there any ways we can make it not choppy, thanks.

I think you should go with the sizing cell.

Please try with this or share the cell's .xib files so that automatic sizing will be enabled.
