Answer 1

To prevent scrolling to top, you should save heights of cells when they loads and give exact value in tableView:estimatedHeightForRowAtIndexPath:

// declare cellHeightsDictionary
NSMutableDictionary *cellHeightsDictionary;

// initialize it in ViewDidLoad or other place
cellHeightsDictionary = @{}.mutableCopy;

// save height
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    [cellHeightsDictionary setObject:@(cell.frame.size.height) forKey:indexPath];
}

// give exact height value
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSNumber *height = [cellHeightsDictionary objectForKey:indexPath];
    if (height) return height.doubleValue;
    return UITableViewAutomaticDimension;
}
