我有一个 3 类别,我将其用作一个部分。在该部分中,我必须填充字典数组中的数据。这是我的代码:-
var sections = [Category A, Category B, Category C]
var itemsA = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
var itemsB = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
var itemsC = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
func numberOfSections(in tableView: UITableView) -> Int {
return self.sections.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return self.sections[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return ??
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "StoreCell") as! UITableViewCell
????
????
return cell
}
我需要明智地填充到表类别中的项目数组。如果有人能回答。谢谢!
最佳答案
使用自定义结构
struct Category {
let name : String
var items : [[String:Any]]
}
var sections = [Category]()
let itemsA = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
let itemsB = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
let itemsC = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
sections = [Category(name:"A", items:itemsA),
Category(name:"B", items:itemsB),
Category(name:"C", items:itemsC)]
func numberOfSections(in tableView: UITableView) -> Int {
return self.sections.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return self.sections[section].name
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let items = self.sections[section].items
return items.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "StoreCell") as! UITableViewCell
let items = self.sections[indexPath.section].items
let item = items[indexPath.row]
print(item["ItemId"] as? String)
return cell
}
如果您对字典也使用自定义结构,您仍然可以改进代码。
