Question

我有一个tableview单元格，里面有集合视图。

CollectionView包含来自服务器的图像。

我想要用户点击的特定图像。即让Tableview有4行。在第四行中，我在每个tableview行中都有集合。当我点击第3行collectionview单元格时，我必须从该行获取该图像。

代码在这里

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    cell = (ISclassifiedCell*)[_isclassifed_tblview dequeueReusableCellWithIdentifier:@"ISclassifiedCell" forIndexPath:indexPath];
[cell.layer setCornerRadius:4.0f];
[cell.layer setMasksToBounds:YES];
     cell.profile_img.layer.cornerRadius=4.0f;
    cell.profile_img.layer.masksToBounds = YES;
    cell.iseventtype_lbl.text=[[isclassifiedarray objectAtIndex:indexPath.section]valueForKey:@"title"];
cell.eventtype_lbl.text=[[isclassifiedarray objectAtIndex:indexPath.section]valueForKey:@"category"];
cell.description_lbl.text=[[isclassifiedarray objectAtIndex:indexPath.section]valueForKey:@"description"];

    UIFont *font=[UIFont fontWithName:@"Montserrat" size:14.0];

    CGFloat size = [self getLabelHeightForString:cell.description_lbl.text font:font];
    cell.description_lbl.frame=CGRectMake(cell.description_lbl.frame.origin.x, cell.description_lbl.frame.origin.y, cell.description_lbl.frame.size.width, size);
NSString *clubberid=[NSString stringWithFormat:@"%@",[[isclassifiedarray objectAtIndex:indexPath.section]valueForKey:@"clubberId"]];
    cell.clubbername_lbl.text=[[isclassifiedarray objectAtIndex:indexPath.section]valueForKey:@"clubberName"];

if ([clubberid isEqualToString:[NSString stringWithFormat:@"%@",mainclubberId]]) {

    [cell.editbutnoutlet setImage:[UIImage imageNamed:@"note-interface-symbol"] forState:UIControlStateNormal];
    cell.pokebtnoutlet.hidden=YES;
    cell.editbutnoutlet.hidden=NO;
    cell.editbutnoutlet.tag = indexPath.section;
    [cell.editbutnoutlet addTarget:self action:@selector(editButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
    [_providertbl reloadData];
}else{

 [cell.pokebtnoutlet setImage:[UIImage imageNamed:@"hold"] forState:UIControlStateNormal];
    cell.pokebtnoutlet.hidden=NO;
    cell.editbutnoutlet.hidden=YES;
    cell.pokebtnoutlet.tag = indexPath.section;
    [cell.pokebtnoutlet addTarget:self action:@selector(pokeButtonClicked:) forControlEvents:UIControlEventTouchUpInside];

}
NSString *imgUrl = [NSString stringWithFormat:@"%s/presignin/clubber/getImage?clubberId=%@",urlPath,clubberid];

 NSURL *imageURL=[NSURL URLWithString:imgUrl];

cell.imgcollection_view.dataSource=self;
    cell.selectionStyle = UITableViewCellSelectionStyleNone;
    //cell.imgcollection_view.allowsSelection=NO;
return cell;
}
 }

示例TableView代码：

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 3;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CellTableTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellCol"];
// Give Tag to CollectionView
    cell.collectionView.tag = indexPath.row;
    return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"%ld",(long)indexPath.row);

}

示例ColleCtionView代码：

-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 3;
}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    UICollectionViewCell *celll = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];
    celll.contentView.backgroundColor = [UIColor greenColor];
    return celll;
}

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

Answer 2

设置UITableView时，将标签设置为UICollectionView。

as

collectionView.tag = indexPath.row

并在collectionViewDidSelect委托方法中检查collectionView的标签
