在github中有许多大牛封装好的第三发类库，其中有个自适应cell高度的类库

model类

commentsModel

#import "JSONModel.h"
#import "getCommentData.h"

@interface commentsModel : JSONModel
@property(nonatomic,copy)NSArray<getCommentData> *commentList;
@end

#import "commentsModel.h"

@implementation commentsModel

@end

getCommentData

#import "JSONModel.h"

@protocol getCommentData

@end

@interface getCommentData : JSONModel

@property(nonatomic,copy)NSString *message;
@property(nonatomic,copy)NSString *nickName;
@property(nonatomic,copy)NSString *createTimeStr;
@end

#import "getCommentData.h"

@implementation getCommentData

@end

控制器

#import "commentsTableViewController.h"
#import "commentsModel.h"
#import "commentCell.h"
@interface commentsTableViewController ()

具体自定义cell的代码

#import <UIKit/UIKit.h>
@class getCommentData;
@interface commentCell : UITableViewCell
@property(nonatomic,strong)getCommentData *commentData;
@property(nonatomic,strong)UILabel *nameLabel;
@property(nonatomic,strong)UILabel *titleLabel;
@property(nonatomic,strong)UILabel *dateLabel;
@end

#import "commentCell.h"
#import "commentsModel.h"
@implementation commentCell

    _commentData=commentData;
    _titleLabel.text=commentData.message;
    _dateLabel.text=commentData.createTimeStr;
    _nameLabel.text=commentData.nickName;

}

- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        [self setup];
    }
    return self;
}

    _nameLabel=[UILabel new];
