how to get the data in array of dictionary in swift? - arrays

Question

I want to save the subcategory data in this form [[value1,value2,...],[value1, value2],[value1],.....] in the following code
var subcategories = [SubCategory]()
for (_, item) in json {
//do something with item.id, item.name
for (_, subcategory) in item["subcategory"] {
let subcategory = SubCategory(
id: Int(subcategory ["id"].stringValue),
name: subcategory ["name"].string,
desc: subcategory ["desc"].string,
image: subcategory ["image"].string,
coupon: Int(subcategory ["coupon"].stringValue),
icon: subcategory ["icon"].string,
order: Int(subcategory ["order"].stringValue),
aname: subcategory ["aname"].string,
options: Int(subcategory ["options"].stringValue),
items: subcategory ["items"].arrayObject
)
subcategories.append(subcategory)
}
print(subcategories.count)
for sub in subcategories {
print(sub.name)
print(sub.id)
print(sub.desc)
self.SUBCATNAME.append(sub.name!)
self.SUBARRAY?.append(self.SUBCATNAME)
}
print(self.SUBCATNAME)
print(self.SUBARRAY)
}
I need to append all the subcategory name in an array of dictionary like the above structure. Here i created SUBARRAY as var SUBARRAY:[[String]] = []. but the value is coming as nil. Here i am getting the json data from Api using Swiftyjson. How to implement this??
my sample json data is as below:
like wise so many subcategories are there
[
{
"id": "244",
"name": "PIZZAS",
"subcategory": [
{
"id": "515",
"name": "MARGARITA",
"description": "Cheese and Tomato",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2"
},
{
"id": "516",
"name": "ABC",
"description": "HNDDSGHFD",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2",
},
{
"id": "516",
"name": "DEF",
"description": "HFDGFJJFHFKH",
"image": "",
"icon": "",
"coupon": "1",
"order": "1",
"aname": "",
"options": "2",
}
]
},
{
......
}
]

if you try this code
for (NSDictionary *dictionary in ArrCategory)
{
NSMutableArray *sub_cat_data=[dictionary objectForKey:#"sub_cat_data"];
for (NSDictionary *sub_cat_dict in sub_cat_data)
{
NSMutableArray *sub_cat_data=[sub_cat_dict objectForKey:#"sub_data"];
for (NSDictionary *dictionary1 in sub_cat_data)
{
NSMutableDictionary *Dic_Sub_cat=[[NSMutableDictionary alloc]init];
NSString *str_dic_id=[dictionary1 objectForKey:#"sub_id"];
NSString *str_dic_name=[dictionary1 objectForKey:#"sub_name"];
[Dic_Sub_cat setObject:str_dic_id forKey:#"sub_id"];
[Dic_Sub_cat setObject:str_dic_name forKey:#"sub_name"];
[Dic_Sub_cat setObject:#"0" forKey:#"sub_Chekid"];
[New_ArrCategory addObject:Dic_Sub_cat];
}
}
}
swift example
if let results: NSMutableArray = jsonResult["data"] as? NSMutableArray
{
var ArrMoodtype2 : NSMutableArray!
ArrMoodtype2 = NSMutableArray()
ArrMoodtype2 = results
ArrFeel = NSMutableArray()
for var i = 0; i < ArrMoodtype2.count; i++
{
var Dic : NSMutableDictionary!
Dic = NSMutableDictionary()
let tempDic: NSMutableDictionary = ArrMoodtype2[i] as! NSMutableDictionary
let strMoodCatID = tempDic ["mood_cat_id"] as! String
let strMoodID = tempDic ["mood_id"] as! String
let strMoodImage = tempDic ["mood_image"] as! String
let strMoodName = tempDic ["mood_name"] as! String
Dic.setObject(strMoodCatID, forKey: "mood_cat_id")
Dic.setObject(strMoodID, forKey: "mood_id")
Dic.setObject(strMoodImage, forKey: "mood_image")
Dic.setObject(strMoodName, forKey: "mood_name")
ArrFeel.addObject(Dic)
}
}
