SZJsonParser を使用して、サイトから JSON オブジェクトをダウンロードしています。これが私のコードです：

#import <Foundation/Foundation.h>
#import "SZJsonParser.h"

int main(int argc, const char * argv[])
{

    @autoreleasepool
    {

        // insert code here...
        NSURL *url = [[NSURL alloc] initWithString:@"http://mymovieapi.com/?title=Cars"];
        NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
        NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
        NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        NSArray *arr = [str jsonObject];
        for (int i = 0; i < [arr count]; i ++)
        {
            NSLog(@"%@",[arr objectAtIndex:i]);
        }
    }
    return 0;
}

ターミナル アプリを実行すると、次のような出力が表示されます。

「タイトル」をキーとして使用して情報を取得できるように、これを NSDictionary に保存するにはどうすればよいですか?

ありがとう

NSData *theData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:jsonFileName ofType:@"json"]];

NSDictionary *myDictionary = [NSJSONSerialization JSONObjectWithData:theData options:NSJSONReadingMutableContainers error:nil];

これがあなたを助けることを願っています。
