    if (cell == nil) {


        cell = [[EmpViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

        cell.lblAnswer.lineBreakMode = NSLineBreakByWordWrapping;
        cell.lblAnswer.numberOfLines = 0;
        [cell setSelectionStyle:UITableViewCellSelectionStyleGray];

        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"EmpViewCell" owner:self options:nil];

        for (id currentObject in topLevelObjects){
            if ([currentObject isKindOfClass:[UITableViewCell class]]){
                cell =  (EmpViewCell *) currentObject;
                cell.selectionStyle=UITableViewCellSelectionStyleNone;

For new iOS 8 there is a new way to make this simple.

Objective c:

 - (void)viewWillAppear:(BOOL)animated {
      [super viewWillAppear:animated];
      self.tableView.estimatedRowHeight = 40.0; // for example. Set your average height 
      self.tableView.rowHeight = UITableViewAutomaticDimension;
      [self.tableView reloadData];
    }

swift 3.0 :

override func viewWillAppear(animated: Bool) {
    self.tableView.estimatedRowHeight = 40 // for example. Set your average height 
    self.tableView.rowHeight = UITableViewAutomaticDimension
    self.tableView.reloadData()

}

If you have added UILabel inside Storyboard to UITableviewCell, then won't get cell as nil. Then some of your code won't execute i.e., if(cell == nil) because cell is not nil.

In Storyboard do this changes: Make sure you have given top, bottom, leading and trailing constrains to the UILabel to UITableViewCell contentView.

  1. Then set number of lines to UILabel to '0' also Line Break to "Word Wrap".

enter image description here

  1. In Controller for UITableViewDelegate heightForRow method:

    - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        tableView.estimatedRowHeight = 100;
        return UITableViewAutomaticDimension;
    }

This will help to solve above requirement.

You easily achieve this by using UITableViewAutomaticDimension.

Just use below code:

your_tableView.estimatedRowHeight = 100; //or any temorary value as it is going to be replaced after getting dynamic height

your_tableView.rowHeight = UITableViewAutomaticDimension;

NOTE: To work this properly, make sure to apply your all constraints in tableViewCell properly
