it's been a long time I don't use Swift.
I have a response data like this and I saved it into an array named responseData:
[
{
"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
},
Now I wanna group all dictionary with type Switch into one array and I can access to the keys inside it, then present data of both Switch type array and the others type on a UITableView which have 2 section (Switch type in section 0). How can I do it? I have to search some other solution but I don't understand how to apply them to my code for work.
Here is my FilterModel class:
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
}
}
You can filter your response data to get only switches in an array.
responseData.filter {($0.type ?? "") == "Switch"}
And of course != would give you non switches.
