如何将多个数组数据传递到表视图？

Question

这里我在网址中有两个数组，我需要显示如图below所示，我不知道如何在表格视图中实现这一点，如图所示

{
  "Flat": [
    {
      "price": "$5.00", 
      "id": 11, 
      "name": "Fixed"
    }
  ], 
  "United Parcel Service": [
    {
      "price": "$109.12", 
      "id": 1, 
      "name": "worldwide Expedited"
    }, 
    {
      "price": "$120.18", 
      "id": 2, 
      "name": "worldwide Express saver"
    }
  ]
}

分段UITableView可以帮助您摆脱这种情况。我假设arrayss为字典和jsonObj。

// number of rows in table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    var key= self.keys[section]
    print(key)
    var a :[Any]  = arrayss[key] as! [Any]
     return a.count
 }
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 2  // if not fixed self.keys.count or self.arrayss.count
}

// create a cell for each table view row
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    // create a new cell if needed or reuse an old one
    let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
   var key= self.keys[indexPath.section]
   print(key)
   var a :[Any]  = arrayss[key] as! [Any]
   var dictionary = a[indexPath.row] as! [String:Any];
   cell.textLabel.text = dictionary ["name"]+ dictionary ["price"]  // you can set the text from the data model

    return cell
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return self.keys[section]
}

----编辑----

为了从字典中单独获取字典的所有键和值。

 var key = Array(arrayss.keys).sorted(by: >)
 var values = Array(arrayss.values).sorted(by: >)

希望它有所帮助。快乐编码!!
