• 1.需要在model里面再加一個高度的屬性

  @property(nonatomic,assign) float cellHeight;
  

• 2.在model.m文件里兩種操作來控制cell里面文字的大小

  - (void)setText:(NSString *)text{
  
     _text = text;
  
   方法一：
     UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(5, 5,      [UIScreen mainScreen].bounds.size.width-10, 0)];
     label.text = text;
     label.font = [UIFont systemFontOfSize:30];
  
     label.numberOfLines = 0;
  
    CGSize s = [label sizeThatFits:CGSizeMake([UIScreen mainScreen].bounds.size.width-10, MAXFLOAT)];
    self.cellHeight = s.height + 310;
  
   方法二：
    CGSize size = [text boundingRectWithSize:CGSizeMake([UIScreen mainScreen].bounds.size.width-20, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:30]} context:nil].size;
  
   self.cellHeight = size.height + 310;
    
   }
  

• 3.自定義的label在重寫UITableViewCell里面進行返回model的高度

   -(void)setModel:(ModelCell *)model
  {
      _model = model;
  
      self.iconImage.image = [UIImage imageNamed:model.icon];
  
      self.Labeltext.font = [UIFont systemFontOfSize:30];
  
      CGRect rect = self.Labeltext.frame;
  
      rect.size.height = model.cellHeight-310;
      self.Labeltext.numberOfLines = 0;
  
      self.Labeltext.frame = rect;
  
      NSString *string = [NSString stringWithFormat:@"      %@",model.text];
  
      self.Labeltext.text = string ;
  
   }
  

需要強調的是：2里面和3里面字體的大小要保持一致，還有寬度

• 4.在UITableViewController 里面cell高度返回里面寫入

    -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      ModelCell *model = dataArray[indexPath.row];
      return model.cellHeight;
  }
