使用相同数组的不同索引处的对象填充CollectionView和TableView
我想在CollectionView中显示“group_type”== 1的产品，在TableView中显示“group_type”== 2的产品。
我想填充TableView的顺序，其中“group_title”将作为行的数组“产品”中的节标题和产品。 以下是我的JSON。
我需要什么Swift代码？
"product_groups": [ { "group_title": "Recommended", "group_type": 1, "products": [ { "product_id": 1, "product_name": "Product 1", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 2, "product_name": "Product 2", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 3, "product_name": "Product 3", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 4, "product_name": "Product 4", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 5, "product_name": "Product 5", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 6, "product_name": "Product 6", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" }, { "product_id": 7, "product_name": "Product 7", "product_price": "Rs 1,999/-", "product_category": "Equipment & Chairs", "product_image": "https://project-isdental-cammy92.c9users.io/api/images/products/product_1.jpg", "product_description": "Description 1" } ] }, { "group_title": "Offers", "group_type": 2, "products": [ { "product_id": 8, "product_name": "Product 8", "product_price": "Rs 1,999/-", "product_category": "Materials & Consumables", "product_image": "", "product_description": "Description 1" }, { "product_id": 9, "product_name": "Product 9", "product_price": "Rs 1,999/-", "product_category": "Materials & Consumables", "product_image": "", "product_description": "Description 1" }, { "product_id": 10, "product_name": "Product 10", "product_price": "Rs 1,999/-", "product_category": "Materials & Consumables", "product_image": "", "product_description": "Description 1" }, { "product_id": 11, "product_name": "Product 11", "product_price": "Rs 1,999/-", "product_category": "Materials & Consumables", "product_image": "", "product_description": "Description 1" } ] }, { "group_title": "Hot Selling", "group_type": 2, "products": [ { "product_id": 12, "product_name": "Product 12", "product_price": "Rs 1,999/-", "product_category": "Instruments", "product_image": "", "product_description": "Description 1" }, { "product_id": 13, "product_name": "Product 13", "product_price": "Rs 1,999/-", "product_category": "Instruments", "product_image": "", "product_description": "Description 1" }, { "product_id": 14, "product_name": "Product 14", "product_price": "Rs 1,999/-", "product_category": "Instruments", "product_image": "", "product_description": "Description 1" }, { "product_id": 15, "product_name": "Product 15", "product_price": "Rs 1,999/-", "product_category": "Instruments", "product_image": "", "product_description": "Description 1" }, { "product_id": 16, "product_name": "Product 16", "product_price": "Rs 1,999/-", "product_category": "Instruments", "product_image": "", "product_description": "Description 1" } ] } 你可以使用数组的过滤方法：
//this filter will return you all objects whose group type is equal to 1 let collectionArray = (product_groups?.filter({$0.group_type == 1})) //this filter will return you all objects whose group type is equal to 2 let tableArray = (product_groups?.filter({$0.group_type == 2}))
对于组标题是部分标题：
- (nullable NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { return tableArray[section].group_title }
要在每个单元格中显示产品：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //cell code... cell.titleLabel.text = tableArray[indexPath.section][indexpPath.row].product_name // cell code }
