How to parse specific Json Array - objective-c

Question

I have a Json array like this:
{"Response":{"Token":"///","Name":"///","Surname":"///","Phone":"///","Street":"///","Interno":"///","PostalCode":"///","City":"///","Province":{"ID":"///","Code":"///","Name":"///"},"Email":"///#gmail.com"},"Error":false,"ErrorDetails":null}
How can I parse the values inside Response and inside Province using objective-c?
I tried with the following code:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
// Create an array to store the locations
if(_fproducts == nil)
{
_fproducts = [[NSMutableArray alloc] init];
}
// Parse the JSON that came in
NSError *error;
jsonArray = [NSJSONSerialization JSONObjectWithData:_downloadedData options:NSJSONReadingAllowFragments error:&error];
// Loop through Json objects, create question objects and add them to our questions array
for (int i = 0; i < jsonArray.count; i++)
{
NSDictionary *jsonElement = jsonArray[i];
// Create a new location object and set its props to JsonElement properties
LoginCredentials *newFProduct = [[LoginCredentials alloc] init];
newFProduct.token = jsonElement[#"Id"];
newFProduct.nomeUser = jsonElement[#"nome"];
NSLog(#"TOKEN:%#", newFProduct.token);
NSLog(#"NOME:%#", newFProduct.nomeUser);
// Add this question to the locations array
[_fproducts addObject:newFProduct];
}
// Ready to notify delegate that data is ready and pass back items
if (self.delegate)
{
[self.delegate itemsDownloaded:_fproducts];
}
}
But I can't parse the values inside Response.. Do i need to create an array of Response and then parse it?

Convert all in NSDictionary, not in NSArray, and then:
jsonDictionary = [NSJSONSerialization JSONObjectWithData:_downloadedData options:NSJSONReadingAllowFragments error:&error];
if(!error) {
NSDictionary* response = jsonDictionary[#"response"];
if(response) {
NSDictionary* province = response[#"province"];
NSLog("Province: %#", province);
/* here you can save all your values */
if(province) {
NSString* identificator = province[#"ID"];
NSString* code = province[#"Code"];
NSString* name = province[#"Name"];
}
}
}
An elegant way to do this is creating your custom interface:
Province.h
#interface Province : NSObject
- (id)initWithDictionary:(NSDictionary*)dictionary;
- (nonatomic, strong) NSString* identificator;
- (nonatomic, strong) NSString* code;
- (nonatomic, strong) NSString* name;
#end
Province.m
#implementation Province
- (id)initWithDictionary:(NSDictionary*)dictionary {
self = [super init];
self.identificator = dictionary[#"ID"];
self.code = dictionary[#"Code"];
self.name = dictionary[#"Name"];
return self;
}
#end
So your code becomes:
if(!error) {
NSDictionary* response = jsonDictionary[#"response"];
if(response) {
NSDictionary* provinceDictionary = response[#"province"];
if(province) {
Province* province = [Province initWithDictionary:provinceDictionary];
}
}
}
