I am using Obj-c and I can get the actor brad pitt but trying to get his id has been a little more challenging.

Here is the query I am using: https://api.themoviedb.org/3/search/person?query=Brad+Pitt&api_key=xxxxxxxxxxx

This is the JSON object I have of Brad Pitt: { page = 1; results = (

{ adult = 0; id = 287; name = "Brad Pitt"; popularity = "7.84036921219752"; "profilepath" = "/kc3M04QQAuZ9woUvH3Ju5T7ZqG5.jpg"; } ); "totalpages" = 1; "total_results" = 1; }

Then I do:

NSDictionary *results = [json objectForKey:@"results"]; //have also tried NSArray and wouldn't it crashed.

This is what it displays:

{ adult = 0; id = 287; name = "Brad Pitt"; popularity = "7.84036921219752"; "profile_path" = "/kc3M04QQAuZ9woUvH3Ju5T7ZqG5.jpg"; }

My question is how do I extract that id number? Thank you again in advance

Got it what happens is results is an array containing one object in the [0] index which itself is an NSDictionary so you need to get the first index then call object for key.

Simple Sample:

NSString *urlString=[NSString stringWithFormat:@"https://api.themoviedb.org/3/search/person?query=Brad+Pitt&api_key=%@",API_KEY];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data=[NSData dataWithContentsOfURL:url];
NSError *e = nil;

NSDictionary *dic1 = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e];

NSDictionary *dic2=[dic1 objectForKey:@"results"];

for(NSDictionary *itemDic2 in dic2)
{
    NSLog(@"For each row... This row has id=%@",[itemDic2 objectForKey:@"id"]);
}
