iOS：具有多个动态部分的uitableview目标c

Question

我收到此 API 响应我想将所有这些数据放入 UITableView 部分我为标题的标题创建一个数组但现在我正在尝试但无法为我必须显示到单元格中的内部数据创建数组. 请帮助我将这些数据填充到带有部分的 tableview 中。

我正在使用以下代码将数据显示到 tableview 中： DataArray 包含“赞助商”键内的值

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [DataArray count];
}


-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    return [DataArray objectAtIndex:section];
}



-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [[DataArray objectAtIndex:section] count];
}


-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }
    cell.textLabel.font=[UIFont fontWithName: @"Arial" size: 14.0 ];

    cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;

    //to hide extra cell from table
    sponsorTable.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

    /*UIView * bkView = (UIView*)[cell viewWithTag:150];
    if(indexPath.row % 2 == 0)
    {
        bkView.backgroundColor = [UIColor whiteColor];
        //cell.backgroundColor = [UIColor whiteColor];
    }
    else
    {
        bkView.backgroundColor = [UIColor colorWithRed:234/255.0 green:236/255.0 blue:235/255.0 alpha:1];
    }*/



    NSString* name = [[DataArray objectAtIndex:indexPath.row]valueForKey:@"sp_name"];
    NSLog(@"-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=%@",name);
    UILabel * nameLbl = (UILabel *)[cell viewWithTag:102];
    nameLbl.text = name;



    NSString * urlstring = [[DataArray objectAtIndex:indexPath.row]valueForKey:@"sp_logo"];
    NSLog(@"urlStr is %@",urlstring);
    NSString * completeString = [NSString stringWithFormat:@"http:****************",urlstring];
    NSLog(@"Complete Url string is %@",completeString);
    UIImageView * imgVw = (UIImageView *)[cell viewWithTag:101];

    cell.imageView.layer.cornerRadius = cell.imageView.frame.size.width / 2;
    cell.imageView.clipsToBounds = YES;

    NSString *imageUrl = [NSString stringWithFormat:@"%@",completeString];
    dispatch_queue_t imageDownloadQueue = dispatch_queue_create(DISPATCH_QUEUE_PRIORITY_DEFAULT, nil);

    dispatch_async(imageDownloadQueue, ^{
        NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageUrl]];

        dispatch_async(dispatch_get_main_queue(), ^{
            UIImage * image1 = [UIImage imageWithData:imageData];
            imgVw.image = image1;
        });
    });


    return cell;
}

Answer 1

您在这里拥有的是（用NSJSONSerialization 转换）是sponsors 是一个字典，其中每个字典都包含一个数组。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    NSDictionary *sponsers = parsedResponse[@"sponsers"];
    return sponsers.allKeys.count; // For every key we need a section
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    NSDictionary *sponsers = parsedResponse[@"sponsers"];
    NSString *key = sponsers.allKeys[section];
    return key; // The key is the section name

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSDictionary *sponsers = parsedResponse[@"sponsers"];
    NSString *key = sponsers.allKeys[section];
    NSArray *content = sponsers[key]; // Each item should be an array
    return content.count; // Return number of items in embedded array
}

- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSDictionary *sponsers = parsedResponse[@"sponsers"];
    NSString *key = sponsers.allKeys[indexPath.section];
    NSArray *content = sponsers[key];
    NSDictionary *item = content[indexPath.row];
    // We have the item. Populate the cell
    ... generate cell ...
    cell.textLabel.text = item[@"sp_name"];
    ...
}

这应该是构建表格视图所需的所有信息。如果您在填充单元格数据时遇到问题，我建议您再问一个具体的问题。

Answer 2

您必须设置特定的键，并且该键必须存储“部分值”。因此您可以轻松获取部分的值。您的字典设置如下所示。

"data" : [
    {
      “Section Title“ : “Section1”,
      “InnerCellData” : [
        {
        //record 1
        }
       {
        //record 2
        }
      ]
    }
    {
      “Section Title“ : “Section2”,
      “InnerCellData” : [
        {
        //record 1
        }
       {
        //record 2
        }
      ]
    }

  ]

它适合你。
