推荐答案

实现方法

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
   //return appropriate value based on IndexPath.row

  UIFont *font = textLabel.font; // use custom label's font
  NSString *myText = @"your text for row at index path";
  CGSize size = [myText sizeWithFont:font forWidth:textLabel.frame.size.width lineBreakMode:UILineBreakModeWordWrap];
  return (size.height+20); //10 pixels space above the textlabel and below 10 pixels space
}
