TableViewCell内嵌collectionView

这篇内容和上篇http://www.jianshu.com/p/b5346ebb8b28 TableViewCell内嵌ScrollView
内容用的方法相似，因为UICollectionView继承UIScrollView，所以用法都差不多
下面上代码:
创建一个继承UICollectionView的类QHCollectionView
在QHCollectionView.h中添加接口方法

@interface QHCollectionView : UICollectionView
/**
  *  @frame: 外界传来的frame 即collectionView的大小
  *
  *  @itemSize: 即collectionViewCell上的Item大小
  *
  *  @imagerArr: 外界存放UIImage的数组
  */
- (instancetype)initWithFrame:(CGRect)frame collectionViewItemSize:(CGSize)itemSize withImageArr:(NSArray *)imagerArr;
@end

在QHCollectionView.m中

#import "QHCollectionView.h"

#define cellID @"cellID"
@interface QHCollectionView ()<UICollectionViewDelegate, UICollectionViewDataSource>
@property (nonatomic, strong) UICollectionViewFlowLayout *layout;
@property (nonatomic, assign) CGSize ItemSize;
@property (nonatomic, strong) NSArray *ImageArray;
@end
@implementation QHCollectionView
- (UICollectionViewFlowLayout *)layout {
    if (!_layout) {
        _layout = [[UICollectionViewFlowLayout alloc] init];
        _layout.itemSize = self.ItemSize;
        _layout.minimumLineSpacing = 10.0;
        _layout.minimumInteritemSpacing = 0.0;
        _layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
        _layout.sectionInset = UIEdgeInsetsMake(10, 10, 10, 10);
    }
    return _layout;
}
- (instancetype)initWithFrame:(CGRect)frame collectionViewItemSize:(CGSize)itemSize withImageArr:(NSArray *)imagerArr {
    _ItemSize = itemSize;
    if (self = [super initWithFrame:frame collectionViewLayout:self.layout]) {
//        [self setLayout:self.layout];
        _ImageArray = imagerArr;
        self.bounces = NO;
        self.pagingEnabled = NO;
        self.showsHorizontalScrollIndicator = NO;
        self.delegate = self;
        self.dataSource = self;
        [self registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:cellID];
    }
    return self;
}

#pragma mark - UICollectionViewDelegate --- UICollectionViewDataSource
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return self.ImageArray.count;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellID forIndexPath:indexPath];
    [cell.contentView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; //

    UIImageView *imageV = [[UIImageView alloc] initWithImage:_ImageArray[indexPath.row]];
    CGRect imageFrame = imageV.frame;
    imageFrame.size = _ItemSize;
    imageV.frame = imageFrame;
    [cell.contentView addSubview:imageV];
    return cell;
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"第%ld分区--第%ld个Item", indexPath.section, indexPath.row);
}

@end

最后在ViewController.m中导入头文件 以及调用

#import "ViewController.h"
#import "QHCollectionView.h"
@interface ViewController ()<UITableViewDelegate, UITableViewDataSource>
@property (nonatomic, strong) UITableView *tableView;
@end

@implementation ViewController
- (UITableView *)tableView {
    if (!_tableView) {
        _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:(UITableViewStylePlain)];
        _tableView.delegate = self;
        _tableView.dataSource = self;
        [self.view addSubview:_tableView];
    }
    return _tableView;
}
- (void)viewDidLoad {
    [super viewDidLoad];
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:NSStringFromClass([UITableViewCell class])];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return 200;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return 2;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:NSStringFromClass([UITableViewCell class]) forIndexPath:indexPath];
    UIImage *image1 = [UIImage imageNamed:@"12.jpg"];
    UIImage *image2 = [UIImage imageNamed:@"19.jpg"];
    UIImage *image3 = [UIImage imageNamed:@"25.jpg"];
    UIImage *image4 = [UIImage imageNamed:@"29.jpg"];
    NSArray *array = @[image1, image2, image3, image4, image1, image2, image3, image4];
    
    QHCollectionView *CollectionView = [[QHCollectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200) collectionViewItemSize:CGSizeMake(100, 180) withImageArr:array];
    
    [cell.contentView addSubview:CollectionView];
    return cell;
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
