JSON Objective-c - Objects and Arrays Combination - objective-c

Question

My JSON url is http://api.kivaws.org/v1/loans/search.json?status=fundraising
My Objective- code displays page_size : 20 using the following code
NSData *allCourseData=[[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://api.kivaws.org/v1/loans/search.json?status=fundraising"]];
NSError *error;
NSMutableDictionary *JsonObject = [NSJSONSerialization
JSONObjectWithData:allCourseData options:NSJSONReadingMutableContainers
error:&error];
//NSLog(#"json object is: - %#", JsonObject);
//Print Page size
NSLog(#"Page size is %#", [[JsonObject objectForKey:#"paging"] objectForKey:#"page_size"]);
My problem is how do i loop to Loans array to display the following
Example it will display name, display ALL languages, status so output will look like
============================
Name : "Maria Luisa"
languages: es,en
status : "fundraising"
sector : "Retail"
location
country_code : "NI"
Name : "Florence"
languages: en
status : "fundraising"

location
country_code : "KE"

Answer 1

Well the loans array is in the top-level JSON object, so:
NSArray *loans = jsonObject[#"loans"];
for (NSDictionary *loan in loans) {
NSNumber *ident = loan[#"id"];
NSString *name = loan[#"name"];
NSDictionary *description = loan[#"description"];
NSDictionary *location = loan[#"location"];
NSString *country = location[#"country"];
// etc.
}

Answer 2

NSData *allCourseData=[[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://api.kivaws.org/v1/loans/search.json?status=fundraising"]];
NSError *error;
NSMutableDictionary *JsonObject = [NSJSONSerialization
JSONObjectWithData:allCourseData options:NSJSONReadingMutableContainers
error:&error];
// Get loans array from JsonObject
NSArray *loanJsonObject = JsonObject[#"loans"];
// Create a new loans array for store the new items
NSMutableArray *newLoans = [NSMutableArray array];
// Loop loanJsonObject to get items and create new ones
// for then store them in the new loans array
for (NSDictionary *loan in loanJsonObject) {
NSDictionary *newLoan = #{
#"name": loan[#"name"],
#"status": loan[#"status"],
#"sector": loan[#"sector"],
#"languages": loan[#"description"][#"languages"],
#"location": #{
#"country": loan[#"location"][#"country"],
#"geo": #{
#"pairs": loan[#"location"][#"geo"][#"pairs"]
}
}
};
[newLoans addObject:newLoan];
}
// the new loans
NSLog(#"newLoans: %#", newLoans);

Answer 3

well your loans object is an array of dictionaries.
By [JsonObject objectForKey:#"loans"] you are getting an array.
then you need to iterate for desired result.
NSArray *arrloans = [JsonObject objectForKey:#"loans"];
for (NSDictionary *dicloans in arrloans) {
NSString *name = [JsonObject objectForKey:#"name"];
NSString *countryCode = [[JsonObject objectForKey:#"location"]objectForKey:#"country_code"]; }
