Я пытаюсь разобрать щебетать пользователь Обновление статус JSON вернулся из Twitter:вопросов Сенсорного JSON с Twitter на прошивке
NSDictionary *publicTimeline = [NSDictionary dictionaryWithJSONData:responseData error:&jsonParsingError];
NSLog(@"%@ - %@",publicTimeline,[publicTimeline class]);
Это даст мне очень аккуратное глядя JSON вернулся из Twitter, но он говорит, класс _NSArrayI - это уже запутывает, но я предполагаю, что это своего рода особенность Touch JSON.
Как только у меня есть словарь, я не могу понять, как с ним что-то сделать. Если я пытаюсь:
NSArray *array = [publicTimeline allKeys];
или
NSArray *tweetsArray = [dict objectForKey:@"results"];
... он выходит из строя из-за непризнанного селектора.
В течение жизни я не могу найти практических примеров того, как использовать библиотеку Touch JSON для фактического захвата объектов. Я имею в виду, как мне захватить первый твит? Как насчет даты внутри этого твита?
EDIT: Это то, что NSLog говорит он выглядит:

Как выглядит publicTimeline? Поскольку ваш журнал говорит, что это массив, конечно, всеKeys и objectForKey будут разбиваться. Можете ли вы показать пример того, что вы получаете от метода dictionaryWithJSONData:? – rdelmar
