tableView镶嵌加入CollectionView实现方法

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

 #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(, , , );
     }
     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(, , 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 ;
 }
 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
     return ;
 }
 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:NSStringFromClass([UITableViewCell class]) forIndexPath:indexPath];
     UIImage *image1 = [UIImage imageNamed:@"1.jpg"];
     UIImage *image2 = [UIImage imageNamed:@"2.jpg"];
     UIImage *image3 = [UIImage imageNamed:@"3.jpg"];
     UIImage *image4 = [UIImage imageNamed:@"4.jpg"];
     NSArray *array = @[image1, image2, image3, image4, image1, image2, image3, image4];//可以自己导入喜欢的图片

     QHCollectionView *CollectionView = [[QHCollectionView alloc] initWithFrame:CGRectMake(, , self.view.frame.size.width, ) collectionViewItemSize:CGSizeMake(, ) withImageArr:array];

     [cell.contentView addSubview:CollectionView];
     return cell;
 }
 - (void)didReceiveMemoryWarning {
     [super didReceiveMemoryWarning];
     // Dispose of any resources that can be recreated.
 }

 @end

可以优化，创建一个类继承tableViewcell，重写，这里就不在上传代码了。
