 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 ()
@property(nonatomic,strong)NSArray *commentsArray;
@end

@implementation commentsTableViewController

        NSData *data=[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"comment_list.json" ofType:nil]];
        commentsModel *commensM=[[commentsModel alloc]initWithData:data error:nil];
        _commentsArray=commensM.commentList;
    }
    return _commentsArray;
}

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

-(void)setCommentData:(getCommentData *)commentData{

    _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;
}

-(void)setup{
    _nameLabel=[UILabel new];
    [self.contentView addSubview:_nameLabel];
    _nameLabel.textColor=[UIColor colorWithRed:0.891 green:0.549 blue:0.073 alpha:1.000];
    _nameLabel.font=[UIFont systemFontOfSize:15];

}

- (void)awakeFromNib {
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

}
