cell图文混排

首先创建一个plist文件
ViewController.m中

#import "ViewController.h"
#import "Model.h"
#import "MyTableViewCell.h"
@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>
{
    NSMutableArray  *arr;
    UITableView  *table;
}
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //初始化plist文件数据
    
    NSString *path = [[NSBundle mainBundle]pathForResource:@"user"ofType:@"plist"];
    NSArray *dataArr= [NSArray arrayWithContentsOfFile:path];
    //变量数组初始化Model对象
    arr = [NSMutableArray array];
    for (NSDictionary *dic in dataArr) {
        Model *m = [[Model alloc]init];
        m.headerImg = dic[@"headerImg"];
        m.name = dic[@"name"];
        m.text = dic[@"text"];
        m.img = dic[@"img"];

        //根据文字计算标签高度
        float height = [dic[@"text"] boundingRectWithSize:CGSizeMake(400, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont systemFontOfSize:15],NSFontAttributeName, nil] context:nil].size.height;
        m.height = height;
        [arr addObject:m];
    }
        //初始化表格
        table = [[UITableView alloc]initWithFrame:self.view.bounds];
        table.dataSource = self;
        table.delegate = self;
        [self.view addSubview:table];
        
        //创建头部图片视图
        UIImageView *img = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200)];
        img.image = [UIImage imageNamed:@"headerImage1.jpg"];
        table.tableHeaderView = img;
    }

    //设置行数
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
        return arr.count;
    }
    //设置单元格内容
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *cellid = @"cellid";
        MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellid];
        if (!cell) {
            cell = [[MyTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellid];
        }
        //获取字典
        Model *m = arr[indexPath.row];
        //设置头像
        cell.headerImg.image = [UIImage imageNamed:m.headerImg];
        //设置名字
        cell.nameLab.text = m.name;
        //设置内容
        cell.textLab.text = m.text;
        cell.textLab.frame = CGRectMake(10, 80, 400, m.height);
        //设置图片
        cell.img.image = [UIImage imageNamed:m.img];
            cell.img.frame = CGRectMake(100, m.height + 90, 200, 200);
        return cell;
    }
    //设置单元格高度
    -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        Model *m = arr[indexPath.row];
        //根据有无图片设置单元格高度
        if ([m.img isEqualToString:@""]) {
            return m.height + 90;
        }else{
            return m.height + 300;
        }
    }
    //表格下拉响应方法
    - (void)scrollViewDidScroll:(UIScrollView *)scrollView
    {
        CGFloat width = self.view.frame.size.width;
        // 图片宽度
        CGFloat yOffset = scrollView.contentOffset.y;
        // 偏移的y值
        if(yOffset < 0)
        {CGFloat totalOffset = 200 + ABS(yOffset);
            CGFloat f = totalOffset / 200;
            //拉伸后的图片的frame应该是同比例缩放。
            table.tableHeaderView.frame =  CGRectMake(- (width *f-width) / 2, yOffset, width * f, totalOffset);
        }
    }
    @end

Model.h中

#import <Foundation/Foundation.h>

@interface Model : NSObject
@property(nonatomic,strong)NSString *headerImg,*name,*text,*img;

@end

MyTableViewCell.h中

#import <UIKit/UIKit.h>

//定义属性头像视图、名字标签、内容标签、图片视图
@property (nonatomic,strong)UIImageView *headerImg,*img;

MyTableViewCell.m中

#import "MyTableViewCell.h"

@implementation MyTableViewCell


//初始化头像视图
- (UIImageView *)headerImg
