iOS アプリで TMDB から人気の動画データを取得しています。しかし、そこから意味のあるデータを解析して取得するのに大きな問題があります。私はiOSがまったく初めてです。私はWindows Phoneで同様のことを行いました.Pocoを作成し、DataContractJsonSerializerを使用してデータを解析しました。しかし、iOSでこれを行う方法についてはまったくわかりません。この文字列から id、original_title、ポスター パスを取得したいと思います。

this is the data i am getting

今まで試したコード

[MYCloud callFunctionInBackground:@"popularMovie"
                   withParameters:@{@"movie": @" "}
                            block:^(id response, NSError *error) {
                                if (!error) {
                                    // ratings is 4.5
                                    NSArray *movieArray;
                                    movieArray = [response allValues];
                                    NSDictionary *firstObject = [movieArray objectAtIndex:0];
                                    NSDictionary *entities = [firstObject objectForKey:@"results"];

                                    NSLog(@"json :%@",[response description]);

NSDictionary *entities = [firstObject objectForKey:@"results"]; でクラッシュします。

================================================== ==================================== これは試行時のクラッシュログです

NSDictionary *blah = [NSJSONSerialization JSONObjectWithData:response options:0 error:nil];

トップレベルのオブジェクトは NSDictionary です。

そう...

NSDictionary *blah = [NSJSONSerialization JSONObjectWithData:theData options:0 error:nil];

これにより、データが使用可能なオブジェクトに変換されます。
