新建HotModel 在hot里属性比如

@property(nonatomic,copy)NSString*img,*label,*sLabel;

然后新建继承CollectionViewCell的一个文件在点h里创建属性

@property(nonatomic,strong)UIImageView *imageView;

@property(nonatomic,strong)UILabel *titleLabel;

@property(nonatomic,strong)UILabel *cedLabel;

@property(nonatomic,strong)HotModel *model;

点m

-(instancetype)initWithFrame:(CGRect)frame{

    self = [super initWithFrame:frame];

    if (self) {

        _imageView = [[UIImageView alloc] init];

        [self.contentView addSubview:_imageView];

        _titleLabel = [[UILabel alloc] init];

        [self.contentView addSubview:_titleLabel];

        _cedLabel = [[UILabel alloc] init];

        [self.contentView addSubview:_cedLabel];

    }

    return self;

}

-(void)layoutSubviews{

    _imageView.frame = CGRectMake(10, 10, SCREEN_RATE_640_WIDTH(60), SCREEN_RATE_640_WIDTH(60));

    _titleLabel.frame = CGRectMake(VIEW_RIGHT(_imageView)+10, VIEW_Y(_imageView), Contenview_Width - 30 - SCREEN_RATE_640_WIDTH(60), VIEW_HEIGHT(_imageView));

    _cedLabel.frame = CGRectMake(VIEW_X(_imageView), VIEW_BUTTOM(_imageView) +10, Contenview_Width - 20, Contenview_Height - 40 - SCREEN_RATE_640_WIDTH(60));

    _cedLabel.numberOfLines = 0;

}

-(void)setModel:(HotModel *)model{

    _imageView.image = [UIImage imageNamed:model.img];

    _titleLabel.text = model.label;

    _cedLabel.text = model.sLabel;

}

在viewControllr

倒入前两个头文件

#import "ViewController.h"#import "define.h"#import "HotCollectCollectionViewCell.h"#import "HotModel.h"@interface ViewController ()@property(nonatomic,strong)UICollectionView *collectionView;

@end

@implementation ViewController

-(void)collectionview{

    flowlayout.itemSize = CGSizeMake((SCREEN_WIDTH - 30)/2.0, (SCREEN_WIDTH - 30)/2.0 *4/5);

    flowlayout.scrollDirection = UICollectionViewScrollDirectionVertical;

    flowlayout.minimumLineSpacing = 10;

    flowlayout.minimumInteritemSpacing = 10;

    _collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(0, 64, SCREEN_WIDTH, SCREEN_HEIGHT- 64 - 49) collectionViewLayout:flowlayout];

_collectionView.backgroundColor = [UIColor whiteColor];

    _collectionView.delegate = self;

    _collectionView.dataSource = self;

    [_collectionView registerClass:[HotCollectCollectionViewCell class] forCellWithReuseIdentifier:@"cell"];

    [self.view addSubview:_collectionView];

}

- (void)viewDidLoad {

    [super viewDidLoad];

    self.view.backgroundColor = [UIColor lightGrayColor];

    [self collectionview];

}

-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{

    return 20;

}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *str = @"cell";

    HotCollectCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:str forIndexPath:indexPath];

    if (!cell) {

        cell = [[HotCollectCollectionViewCell alloc] init];

    }
