在 UITableviewCell 中使用 UICollection 视图时未调用 UICollectionView 委托方法“didSelectItemAtIndexPath”

Question

我在 UITableviewCell 中使用了 UICollectionView，一切正常，仍在加载集合视图并显示其单元格，但加载集合视图后，当点击集合视图单元格时，我无法获取集合视图的“didSelectItemAtIndexPath”委托方法。

我的表格视图具有静态单元格，我将集合视图放在该单元格中

还要在上面定义委托和数据源

这是我的代码，调用了数据源方法但未调用委托

#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);
}

也移除collelioview的outlet和delegate和datasource，见OUTPUT HERE

你应该这样写你的代码

- (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);
}
