【中文标题】使用 Swift 将具有相同类型的字典分组到具有完整键和值的数组中【英文标题】：Group a dictionary with same type into an array with full key and value using Swift 【发布时间】：2019-12-01 00:53:31 【问题描述】：好久没用 Swift 了。
我有一个这样的响应数据，我将它保存到一个名为 responseData 的数组中：
[
"type": "Switch",
"name": "Switch1",
"search_key": "is_promotion",
"key": "is_promotion=1",
"icon": ""
,
"type": "Switch",
"name": "Switch2",
"search_key": "shop_type",
"key": "shop_type=2",
"icon": ""
,
"type": "Switch",
"name": "Switch3",
"search_key": "is_certified",
"key": "is_certified=1",
"icon": ""
,
"type": "Switch",
"name": "Switch4",
"search_key": "shop_free_shipping",
"key": "shop_free_shipping=1",
"icon": ""
,
"type": "Switch",
"name": "Switch5",
"search_key": "is_loyalty",
"key": "is_loyalty=1",
"icon": ""
,
"type": "Switch",
"name": "Switch6",
"search_key": "is_using_instant",
"key": "is_using_instant=1",
"icon": ""
,
"type": "Switch",
"name": "Switch7",
"search_key": "is_installment",
"key": "is_installment=1",
"icon": ""
,
"type": "Range",
"name": "Price Range",
"search_key": "level_Price_Max_Min",
"value": [
"option_id": 0,
"option_name": 0
,
"option_id": 0,
"option_name": 10000000
]
,
"type": "ColorTerm",
"name": "Color",
"search_key": "color_key",
"value": [
"option_id": 605,
"value": "Black",
"color_id": 13,
"image": "",
"option_name": "Black",
"background": "#000000",
"option_active": "",
"facet_count": 52655
,
现在我想将类型为 Switch 的所有字典分组到一个数组中，我可以访问其中的键，然后在 UITableView 上显示 Switch 类型数组和其他类型的数据，它们有 2 个部分（Switch 在第 0 部分输入）。我该怎么做？我必须搜索其他一些解决方案，但我不明白如何将它们应用到我的工作代码中。
这是我的 FilterModel 类：
class FilterModel: NSObject, NSCoding, NSCopying
override func copy(with zone: NSZone? = nil) -> Any
// This is the reason why `init(_ model: GameModel)`
// must be required, because `GameModel` is not `final`.
let copy = FilterModel(dict: self.dictionary)
if let arrAttribute = NSArray(array: self.value , copyItems: true) as? [AttributeValueModel]
copy.value = arrAttribute
return copy
override init(dict: Dictionary<String, Any>)
super.init(dict: dict);
value = self.valueParse()
required init?(coder aDecoder: NSCoder)
super.init(coder: aDecoder)
var name: String?
return self.dictionary.getString(forKey: "name")
var icon: String?
return self.dictionary.getString(forKey: "icon")
var search_key: String?
return self.dictionary.getString(forKey: "search_key")
var key: String?
return self.dictionary.getString(forKey: "key")
var type: FilterDisplayType
let type = self.dictionary.getString(forKey: "type")
return self.getType(string: type)
var value: [AttributeValueModel] = [];
func valueParse()-> [AttributeValueModel]
// with switch type, Just set true or false
// Change ParentValue to Child
if type == .Switch
let dict:Dictionary<String, AnyObject> = [
"option_id": "false" as AnyObject,
"option_name": self.name! as AnyObject,
"name": self.name! as AnyObject,
"icon": self.icon! as AnyObject
]
let item = AttributeValueModel(dict:dict);
return [item]
guard let childs = (self.dictionary["value"]) as? [Dictionary<String, AnyObject>]
else return []
var output: [AttributeValueModel] = [];
for aDict in childs
let item = AttributeValueModel(dict:aDict);
if type == .Range && item.option_id == "0"
item.setRangeOptionID(aValue: item.option_name!)
output.append(item);
return output;
///get list AttributeValueModel Selected
func selectedValues() -> [AttributeValueModel]
var output: [AttributeValueModel] = [];
for itemTemp in self.value
if(itemTemp.selected)
if type == .Switch
itemTemp.setSelectedOptionID()
output.append(itemTemp);
return output;
/// make a Filter Item from attributeValues Seleted
func getFilterItem() -> FilterItem?
var itemFilter: FilterItem = FilterItem(key: self.search_key!, value: "")
itemFilter.key = self.search_key!
let output: NSMutableArray = [];
for attItem in self.selectedValues()
if attItem.option_id != ""
output.add(attItem.option_id!);
if(output.count == 0)
return nil;
let valueString = output.componentsJoined(by: ",");
itemFilter.value = valueString;
return itemFilter
///get list AttributeValueModel Selected
func resetToDefault() -> [AttributeValueModel]
var output: [AttributeValueModel] = [];
for itemTemp in self.value
if(itemTemp.selected)
itemTemp.selected = false
if type == .Switch
itemTemp.setSelectedOptionID()
if type == .Range
itemTemp.setRangeOptionID(aValue: itemTemp.option_name!)
output.append(itemTemp);
return output;
//for UI
var wasExpanding = false
var numberOfRow:Int = 0
/************/
var attributeNameLength: Int
var string = ""
for item in valueParse()
string += item.option_name!
return string.count
var lenghtSizeName:Int
var row:Int = 1
var width:CGFloat = 0
let padding:CGFloat = 8
let screen = screenWidth - 50 - 16
for item in valueParse()
let size = ((item.option_name ?? "") as NSString).size(withAttributes: [
NSAttributedStringKey.font : UIFont.fontRegular_Big()
])
let totalWidth = size.width + padding + 16
if totalWidth <= CGFloat(32)
width += 32
if width >= screen
row += 1
width = 32
else
width += totalWidth
if width >= screen
row += 1
width = totalWidth
return row
【问题讨论】：
解释你是如何解码数据的以及数组的定义（数据结构） @JoakimDanielson 我更新了我的 filterModel 类 【参考方案1】：您可以过滤响应数据以在数组中仅获得开关。
responseData.filter ($0.type ?? "") == "Switch"
当然 != 会给你非开关。
【讨论】：
$0 出现错误。据说Type 'FilterModel' has no subscript member。我正在像这样创建我的 responseData：var responseData : [FilterModel]?
那么您应该提供有问题的 filterModel，但是我假设 type 是一个字符串变量，请检查更新的答案以上是关于使用 Swift 将具有相同类型的字典分组到具有完整键和值的数组中的主要内容，如果未能解决你的问题，请参考以下文章
