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-(NSArray *)commentsArray{  if (_commentsArray==nil) {    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;}- (void)viewDidLoad {  [super viewDidLoad];  }- (void)didReceiveMemoryWarning {  [super didReceiveMemoryWarning];  // Dispose of any resources that can be recreated.}#pragma mark - Table view data source- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {  return 1;}- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {  return self.commentsArray.count;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {  static NSString *ID=@"comment";  commentCell *cell=[tableView dequeueReusableCellWithIdentifier:ID];  if (cell==nil) {    cell=[[commentCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ID];  }  cell.commentData=self.commentsArray[indexPath.row];    return cell;}-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{    return [self cellHeightForIndexPath:indexPath cellContentViewWidth:[self cellContentViewWith]];}-(CGFloat)cellContentViewWith{    CGFloat width=[UIScreen mainScreen].bounds.size.width;  if ([UIApplication sharedApplication].statusBarOrientation != UIInterfaceOrientationPortrait && [[UIDevice currentDevice].systemVersion floatValue] < 8) {    width = [UIScreen mainScreen].bounds.size.height;  }  return width;}@end

 

 

 

 

 

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];  _nameLabel.numberOfLines=1;        _titleLabel=[UILabel new];  [self.contentView addSubview:_titleLabel];  _titleLabel.textColor=[UIColor darkGrayColor];  _titleLabel.font=[UIFont systemFontOfSize:15];  _titleLabel.numberOfLines=0;      _dateLabel=[UILabel new];  [self.contentView addSubview:_dateLabel];  _dateLabel.textColor=[UIColor colorWithRed:0.679 green:0.166 blue:0.828 alpha:1.000];  _dateLabel.font=[UIFont systemFontOfSize:15];  _dateLabel.numberOfLines=1;      CGFloat margin=10;  UIView *contentView=self.contentView;      _nameLabel.sd_layout  .leftSpaceToView(contentView,margin)  .topSpaceToView(contentView,margin)  .rightSpaceToView(contentView,margin)  .heightIs(20);        _titleLabel.sd_layout  .leftSpaceToView(contentView,margin)  .topSpaceToView(_nameLabel,2)  .rightSpaceToView(contentView,margin)  .autoHeightRatio(0);    _dateLabel.sd_layout  .leftSpaceToView(contentView,margin)  .topSpaceToView(_titleLabel,5)  .heightIs(20)   .widthIs(150);  [self setupAutoHeightWithBottomViewsArray:@[_titleLabel,_dateLabel,_nameLabel] bottomMargin:margin];}- (void)awakeFromNib {}- (void)setSelected:(BOOL)selected animated:(BOOL)animated {  [super setSelected:selected animated:animated];}@end
