ios - UICollectionView 委托(delegate)方法 "didSelectItemAtIndexPath"在 UITableviewCell 中使用 UICollection View 时未调用

Question

我在我的 UITableviewCell 中使用了 UICollectionView，一切正常，仍在加载 Collection View 并显示其单元格，但是在加载 Collection View 后，当点击 Collection View 单元格时，我无法获得 Collection View 的“didSelectItemAtIndexPath”委托(delegate)方法。

我的表格 View 具有静态单元格，我将 Collection View 放在该单元格中

还要在其上定义委托(delegate)和数据源

这是我的代码，调用了数据源方法但未调用委托(delegate)

#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 delegate 和 datasource 的导出，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);
}
