Use ObjectMapper to parse Dictionary within a Dictionary Swift - ios

Question

My old JSON structure was like this:
{
"parameters": {
"customerId": 9,
"from": "2014-06-05T14:00:00",
"until": "2014-06-05T15:00:00",
"km": 20,
"insurance": false
},
"estimatesPerCategory": {
"2": {
"timeCost": 5,
"kmCost": 6,
...
}
To parse JSON I use ObjectMapper.
This code works very well:
if let myObject = Mapper<CostEstimateResult>().map(JSONObject: JSON) {
}
The class CostEstimateResult looks like this.
class CostEstimateResult : NSObject, Mappable {
var parameters:CostEstimateParameters?
var estimatesPerCategory:[String: CostEstimate]? // CostEstimate.id -> CostEstimate
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
estimatesPerCategory <- map["estimatesPerCategory"]
parameters <- map["parameters"]
}
}
And last but not least my CostEstimate class for estimatesPerCategory
class CostEstimate : NSObject, Mappable {
var timeCost:NSNumber?
...
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
timeCost <- map["timeCost"]
...
}
}
This is working. The mapper in CostEstimateResult will call the mapper in CostEstimates and I get my parsed data.
Now I changed the JSON Structure:
{
"parameters": {
//same like before
},
"estimatesPerCategory": {
"2": {
"total": {
"preTax": {
"value": 1,
"text": "1,00 €"
},
"configTax": false
},
"3": {
//same...
}
}
}
In my opinion in the basic structure nothing changes. estimatesPerCategory is still the same dictionary. The data behind estimatesPerCategory are changed, okay.
The problem is, when I call the mapper ...Mapper<CostEstimateResult>().map... the parameters will be parse, but not the costEstimates. The func mapping in CostEstimate isn't call anymore.
Long story short: It seems that the type of estimatesPerCategory in CostEstimateResult changes with the json structure. I can't figure out which type I need.

Now with new JSON Structure, your Class CostEstimate structure will be changed and a new Class PreTax will be required to be created:
class CostEstimateResult : NSObject, Mappable {
var parameters:CostEstimateParameters?
var estimatesPerCategory:[String: CostEstimate]? // CostEstimate.id -> CostEstimate
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
estimatesPerCategory <- map["estimatesPerCategory"]
}
}
class CostEstimate : NSObject, Mappable {
var total:totalTax?
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
total <- map["total"]
}
}
class totalTax : NSObject, Mappable {
var preTax:PreTax?
var configTax:Bool?
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
preTax <- map["preTax"]
configTax <- map["configTax"]
}
}
class PreTax : NSObject, Mappable {
var value:NSNumber?
var text:String?
override init() {}
required convenience init?(map: Map) {
self.init()
self.mapping(map: map)
}
func mapping(map: Map) {
value <- map["value"]
text <- map["text"]
}
}
