xCode - Mashape API - Unirest

Question

i need some help from you. I found a API on MaShape for Metascore but i just can't get it to work. I used Cocoapod to download Unirest framework and copy pasted the code snippet from Mashape

NSDictionary* headers = @{@"X-Mashape-Authorization": @"wZrjWIiAsqdSLGIh3DQzrKoZ5Y3wlo6E"};
NSDictionary* parameters = @{@"title": @"The Elder Scrolls V: Skyrim", @"platform": 1, };

UNIHttpJsonResponse* response = [[UNIRest post:^(UNIBodyRequest* request) {
  [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

  [request setHeaders:headers];
  [request setParameters:parameters];
}] asJson];

It gave me a bunch of errors and i fixed it to be like this:

NSDictionary* headers = @{@"X-Mashape-Authorization": @"wZrjWIiAsqdSLGIh3DQzrKoZ5Y3wlo6E"};
    NSDictionary* parameters = @{@"title": @"The Elder Scrolls V: Skyrim", @"platform": @"1", };

    UNIHTTPJsonResponse* response = [[UNIRest post:^(UNISimpleRequest* request) {
        [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

        [request setHeaders:headers];
        [request setParameters:parameters];
    }] asJson];

but whenever i go and debug the code and i look inside the response it's empty as if the api didn't work. Can you guys tell me what i'm doing wrong?

Thanks

Your (fixed) code snippet looks fine (the first one was indeed erroneous), and you should be able to print the result like this:

UNIHTTPJsonResponse *response = [[UNIRest post:^(UNISimpleRequest *request) {
    [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];

    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJson];

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
                                                         options:kNilOptions
                                                           error:nil];
NSLog(@"Response status: %ld\n%@", (long) response.code, json);

But rather than doing a synchronous call, I would also suggest you to switch to the asynchronous way, as well as checking for any error during the process and the JSON parsing:

[[UNIRest post:^(UNISimpleRequest *request) {
    [request setUrl:@"https://byroredux-metacritic.p.mashape.com/find/game"];
    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJsonAsync:^(UNIHTTPJsonResponse* response, NSError *error) {
    if (error) {
        // Do something with the error
    }

    NSError *jsonError;
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
                                                         options:kNilOptions
                                                           error:&jsonError];
    if (jsonError) {
        // Do something with the error
    }

    NSLog(@"Async response status: %ld\n%@", (long) response.code, json);

    // Unirest also provides you this which prevents you from doing the parsing
    NSLog(@"%@", response.body.JSONObject);
}];
