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

 1 @interface QHCollectionView : UICollectionView
 2 /**
 3   *  @frame: 外界传来的frame 即collectionView的大小
 4   *
 5   *  @itemSize: 即collectionViewCell上的Item大小
 6   *
 7   *  @imagerArr: 外界存放UIImage的数组
 8   */
 9 - (instancetype)initWithFrame:(CGRect)frame collectionViewItemSize:(CGSize)itemSize withImageArr:(NSArray *)imagerArr;
10 @end

 1 #import "QHCollectionView.h"
 2 
 3 #define cellID @"cellID"
 4 @interface QHCollectionView ()<UICollectionViewDelegate, UICollectionViewDataSource>
 5 @property (nonatomic, strong) UICollectionViewFlowLayout *layout;
 6 @property (nonatomic, assign) CGSize ItemSize;
 7 @property (nonatomic, strong) NSArray *ImageArray;
 8 @end
 9 @implementation QHCollectionView
10 - (UICollectionViewFlowLayout *)layout {
11     if (!_layout) {
12         _layout = [[UICollectionViewFlowLayout alloc] init];
13         _layout.itemSize = self.ItemSize;
14         _layout.minimumLineSpacing = 10.0;
15         _layout.minimumInteritemSpacing = 0.0;
16         _layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
17         _layout.sectionInset = UIEdgeInsetsMake(10, 10, 10, 10);
18     }
19     return _layout;
20 }
21 - (instancetype)initWithFrame:(CGRect)frame collectionViewItemSize:(CGSize)itemSize withImageArr:(NSArray *)imagerArr {
22     _ItemSize = itemSize;
23     if (self = [super initWithFrame:frame collectionViewLayout:self.layout]) {
24 //        [self setLayout:self.layout];
25         _ImageArray = imagerArr;
26         self.bounces = NO;
27         self.pagingEnabled = NO;
28         self.showsHorizontalScrollIndicator = NO;
29         self.delegate = self;
30         self.dataSource = self;
31         [self registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:cellID];
32     }
33     return self;
34 }
35 
36 #pragma mark - UICollectionViewDelegate --- UICollectionViewDataSource
37 - (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
38     return self.ImageArray.count;
39 }
40 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
41     UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellID forIndexPath:indexPath];
42     [cell.contentView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; //
43 
44     UIImageView *imageV = [[UIImageView alloc] initWithImage:_ImageArray[indexPath.row]];
45     CGRect imageFrame = imageV.frame;
46     imageFrame.size = _ItemSize;
47     imageV.frame = imageFrame;
48     [cell.contentView addSubview:imageV];
49     return cell;
50 }
51 - (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
52     NSLog(@"第%ld分区--第%ld个Item", indexPath.section, indexPath.row);
53 }
54 
55 @end

最后在ViewController.m中导入头文件以及调用

 1 #import "ViewController.h"
 2 #import "QHCollectionView.h"
 3 @interface ViewController ()<UITableViewDelegate, UITableViewDataSource>
 4 @property (nonatomic, strong) UITableView *tableView;
 5 @end
 6 
 7 @implementation ViewController
 8 - (UITableView *)tableView {
 9     if (!_tableView) {
10         _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:(UITableViewStylePlain)];
11         _tableView.delegate = self;
12         _tableView.dataSource = self;
13         [self.view addSubview:_tableView];
14     }
15     return _tableView;
16 }
17 - (void)viewDidLoad {
18     [super viewDidLoad];
19     [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:NSStringFromClass([UITableViewCell class])];
20 }
21 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
22     return 200;
23 }
24 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
25     return 2;
26 }
27 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
28     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:NSStringFromClass([UITableViewCell class]) forIndexPath:indexPath];
29     UIImage *image1 = [UIImage imageNamed:@"1.jpg"];
30     UIImage *image2 = [UIImage imageNamed:@"2.jpg"];
31     UIImage *image3 = [UIImage imageNamed:@"3.jpg"];
32     UIImage *image4 = [UIImage imageNamed:@"4.jpg"];
33     NSArray *array = @[image1, image2, image3, image4, image1, image2, image3, image4];//可以自己导入喜欢的图片
34 
35     QHCollectionView *CollectionView = [[QHCollectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200) collectionViewItemSize:CGSizeMake(100, 180) withImageArr:array];
36 
37     [cell.contentView addSubview:CollectionView];
38     return cell;
39 }
40 - (void)didReceiveMemoryWarning {
41     [super didReceiveMemoryWarning];
42     // Dispose of any resources that can be recreated.
43 }
44 
45 @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。
