    }
    return self;

- (void)setStatusFrames:(ImageCellStyle *)statusModle

    _imageStyle = statusModle;
}

#pragma mark 設置數據
- (void)settingData:(ImageCellStyle *)imagecellStyle
{

    self.pictureView.image = [UIImage imageNamed:@"1.png"];

    self.nameView.text = imagecellStyle.name;


    self.muchView.text = imagecellStyle.much;

    self.timeView.text = imagecellStyle.style;


    self.styleView.text = imagecellStyle.time;

.h

#import <Foundation/Foundation.h>

@interface ImageCellStyle : NSObject

@property (nonatomic,copy) NSString *style;
@property (nonatomic,copy) NSString *name;
@property (nonatomic,copy) NSString *time;
@property (nonatomic,copy) NSString *much;
@property (nonatomic,copy) NSString *picture;

- (instancetype) initWithDict: (NSDictionary *)dict;//對象方法

+ (instancetype) weiboWithDict: (NSDictionary *)dict;//類方法

@end

.m

#import "ImageCellStyle.h"

@implementation ImageCellStyle


-(instancetype)initWithDict:(NSDictionary *)dict
 {
    if (self = [super init]) {
         //使用KVC
                 [self setValuesForKeysWithDictionary:dict];
        }
    return self;
}


+(instancetype)weiboModelWithDict:(NSDictionary *)dict
{
    return [[self alloc]initWithDict:dict];
}

@end

controller 方法
.m

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 100.0f;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{


    static NSString *cellIndentifiter = @"CellIndentifiter";

    ActionCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIndentifiter];

    if (cell == nil) {
        cell = [[ActionCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIndentifiter];
    }

    [cell settingData:_image];
    return cell;
}

第二種通過xib創建
1、新建類，基於UITableViewCell
例如 @interface CellSearch : UITableViewCell

2、新建空 xib 文件
例如命名爲 CellSearch.xib （名字要跟類名一樣）
拖一個UITableViewCell控件到xib中
（你可以在這個cell裏面放你想放的東東）

3、使用
經過1、2步，自定義的cell已經建好了
在cellForRowAtIndexPath 方法中使用

CellSearch *cell = [tableView dequeueReusableCellWithIdentifier:@”CellSearch”];
if(!cell) {
cell = [[[NSBundle mainBundle] loadNibNamed:@”CellSearch” owner:self options:nil]lastObject];
}
return cell;

運行看效果

4、關聯xib與類文件（這個關聯我經常弄錯）
(到第3步,你已經可以看到自定義的cell了,但是還不能獲取cell裏面的信息,因爲沒有關聯)
選中CellSearch.xib中的UITableViewCell控件，將類名關聯爲CellSearch
(然後就是Cell內普通的控件關聯了)

5、使用
在cellForRowAtIndexPath 方法中使用
例如：
CellSearch *cell = [tableView dequeueReusableCellWithIdentifier:@”CellSearch”];
if(!cell) {
cell = [[[NSBundle mainBundle] loadNibNamed:@”CellSearch” owner:self options:nil]lastObject];
}
cell.nameTextField.text = @”tom”; //關聯後可以直接設置cell內的控件
return cell;
第三種就是直接在

#import <Foundation/Foundation.h>
#import "Global.h"

@interface YYtg : NSObject
@property(nonatomic,copy)NSString *buyCount;
@property(nonatomic,copy)NSString *icon;
@property(nonatomic,copy)NSString *price;
@property(nonatomic,copy)NSString *title;
YYinitH(tg)
@end

#import "YYtg.h"

@implementation YYtg
YYinitM(tg)
@end

#import "YYViewController.h"
#import "YYtg.h"

@interface YYViewController ()<UITableViewDataSource>
@property(nonatomic,strong)NSArray *tg;
@property (strong, nonatomic) IBOutlet UITableView *tableview;

@end

@implementation YYViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.tableview.rowHeight=100;

}

#pragma mark-  懶加載
-(NSArray *)tg
{
    if (_tg==nil) {
        NSString *fullpath=[[NSBundle mainBundle]pathForResource:@"tgs.plist" ofType:nil];
        NSArray *temparray=[NSArray arrayWithContentsOfFile:fullpath];

        NSMutableArray *arrayM=[NSMutableArray arrayWithCapacity:temparray.count];
        for (NSDictionary *dict in temparray) {
            YYtg *tg=[YYtg tgWithDict:dict];
            [arrayM addObject:tg];
        }
        _tg=[arrayM mutableCopy];
    }
    return _tg;
}

#pragma mark-數據顯示
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return self.tg.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //讀取xib中的數據
//    NSArray *arrayM=[[NSBundle mainBundle]loadNibNamed:@"tgcell" owner:nil options:nil];
//    UITableViewCell *cell=[arrayM firstObject];
    static NSString *identifier=@"tg";
    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell==nil) {
       // cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
        cell= [[[NSBundle mainBundle]loadNibNamed:@"tgcell" owner:nil options:nil] firstObject];
    }

    YYtg *tg=self.tg[indexPath.row];
    //設置數據
    //使用tag
    UIImageView *imgv=(UIImageView *)[cell viewWithTag:1];
    imgv.image=[UIImage imageNamed:tg.icon];
    UILabel *buyCount=(UILabel *)[cell viewWithTag:4];
    buyCount.text=[NSString stringWithFormat:@"已有%@人購買",tg.buyCount];
    UILabel *title=(UILabel *)[cell viewWithTag:2];
    title.text=tg.title;
    UILabel *price=(UILabel *)[cell viewWithTag:3];
    price.text=[NSString stringWithFormat:@"$%@",tg.price];


    //返回cell
    return cell;
}

//隱藏狀態欄
-(BOOL)prefersStatusBarHidden
{
    return YES;
}
@end
