Question

我在UITableviewCell中使用了UICollectionView，一切正常，仍然加载集合视图并显示其单元格，但是在加载集合视图后，我无法得到＆＃34; didSelectItemAtIndexPath＆＃34;在点击集合视图单元格时委托集合视图的方法。

我的表格视图中有静态单元格，我将集合视图放在该单元格中

还要在其上定义委托和数据源

这是我的代码，调用了数据源方法，但没有调用委托

#pragma mark - collectionView data source


- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 10;
}

// The cell that is returned must be retrieved from a call to -dequeueReusableCellWithReuseIdentifier:forIndexPath:
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"collCell" forIndexPath:indexPath];
    UIImageView *imgDocCell = (UIImageView *)[cell viewWithTag:100];
    imgDocCell.image = self.imgFileToChart;
    cell.layer.borderWidth=1.0f;
    cell.layer.borderColor=commonThemeColor.CGColor;
    return cell;
}


#pragma mark - collectionView delegate

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"%@",indexPath);
}

删除collectioview和委托以及数据源的出口，请参阅OUTPUT HERE

你应该像这样编写你的代码

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return 1;   
}

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *MyIdentifier = @"cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    // Here tableviewcell inside one collection view create with tag 10
    UICollectionView *coll =(UICollectionView*)[cell viewWithTag:10];
    coll.delegate = self;
    coll.dataSource = self;

    return cell;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 3;
}

// The cell that is returned must be retrieved from a call to -dequeueReusableCellWithReuseIdentifier:forIndexPath:
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    UICollectionViewCell *cell1 = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell2" forIndexPath:indexPath];
    // in collectionview storyboard one UIImageview with tag 20
    UIImageView *imgDocCell = (UIImageView *)[cell1 viewWithTag:20];
    imgDocCell.image =[UIImage imageNamed:@"add.jpeg"];

    return cell1;
}

#pragma mark - collectionView delegate

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"%@",indexPath);
}

UICollectionView委托方法＆＃34; didSelectItemAtIndexPath＆＃34;在UITableviewCell中使用UICollection视图时不调用
