How to use Map for storing the JSON response in Model Class.

Map

we need to store the JSON response in Model class, when we receive the array of dictionary then we use ” for loop ” for inserting each dictionary data into model object, this way of doing is not good .its better to use Map for inserting the data into model class . for doing this we need to follow this steps:

1: create a Model class like this.

I have taken the example like this:

class ProductCollectionModel: NSObject {

var productName:String = ""

var productImage:String = ""

var descriptionData:String = ""

var id:String = ""

var price:String = ""

init(data: JSON) {

self.productImage = data["thumbNail"].stringValue

self.descriptionData = data["shortDescription"].stringValue

self.id = data["entityId"].stringValue

self.price = data["formatedFinalPrice"].stringValue

self.productName = data["name"].stringValue

}

This is sample model class, which store each dictionary data in this class.

2: Now for ViewModel Class where we make the function to insert the data into the model class.

class ProductCollectionViewModel {

var productCollectionModel = [ProductCollectionModel]()

init(data:JSON) {

if data["productList"].arrayObject != nil{

let arrayData = data["productList"].arrayObject! as NSArray

productCollectionModel = arrayData.map({(value) -> ProductCollectionModel in

return ProductCollectionModel(data:JSON(value))

})

}

Here “productList” is JSON array whose key is “productList” and it contains an array of the dictionary.

like that.

3: Now using this function you can access the model class as an array.

var getProductCollectionData:Array<ProductCollectionModel>{

return productCollectionModel

}
