Question

我需要使用自定义结构的数组填充我的tableview，目前它只会使用相同的数组填充每个部分的表视图。

我追加的地方......

    let shake = Item(name: "Shake", carbs: 20)
    let fries = Item(name: "Fries", carbs: 30)
    let pie = Item(name: "Pie", carbs: 23)

    let beverages = Category(name: "Beverages", items: [shake])
    let chips_fries = Category(name: "Chips & Fries", items: [fries])
    let desserts = Category(name: "Desserts", items: [pie])
    let other = Category(name: "Other Menu Items", items: [])
    let sandwiches_burgers = Category(name: "Sandwiches & Burgers", items: [])
    let sides = Category(name: "Sides", items: [])

    a_w = Restaurant(name: "A&W", categories: [beverages, chips_fries, desserts, other, sandwiches_burgers, sides])

    restaurants = [a_w]

这是我尝试使用Items数组填充表视图...

   var restaurants = [Restaurant]()

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.reloadData()
    // Do any additional setup after loading the view.
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
    let restaurant = restaurants[indexPath.section]
    let category = restaurant.categories[indexPath.section]
    let item = category.items[indexPath.row]
    cell.textLabel!.text = item.name
    return cell
}

override func numberOfSections(in tableView: UITableView) -> Int {
    return restaurants.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    let restaurant = restaurants[section].categories[section]
    return restaurant.items.count
}

}

只会用“摇晃”来填充每个类别。

Answer 1

您必须使用indexPath.row代替indexPath.section。但要更好地回答它，请更新您希望UI的外观。你想要每个餐厅都是一个部分吗？如果是，您如何区分不同的类别？

如果您想要嵌套部分，请参阅本教程： http://sapandiwakar.in/nested-sections-in-uitableview/

tableview填充相同的字符串
