iphone - 在以下示例中如何从 NSSArray 元素获取值？

Question

我有一个 NSArray，所以当我这样做时:

NSLog(@"%@", [jokesArray description]);

我得到以下信息:

(
        {
        "_id" =         {
            "$id" = 4e91fd49c7e24cda74000000;
        };
        author = draper;
        comments =         (
                        {
                author = adias;
                comment = "amazing again";
            }
        );
        created =         {
            sec = 1318118400;
            usec = 0;
        };
        text = "This is a random post again";
        title = "post # 2";
        type =         (
            punjabi
        );
    },
        {
        "_id" =         {
            "$id" = 4e8cf1d6c7e24c063e000000;
        };
        author = faisal;
        comments =         (
                        {
                author = adias;
                comment = amazing;
            },
                        {
                author = nike;
                comment = "I concur";
            }
        );
        created =         {
            sec = 1317772800;
            usec = 0;
        };
        text = "This is a random post";
        title = "post # 1";
        type =         (
            punjabi
        );
    }
)

我如何访问特定元素中的文本键？

我尝试时遇到错误:

[[cell textLabel]setText:[[jokesArray objectAtIndex:[indexPath row]]valueForKey:@"text"]]; 

Answer 1

EXC_BAD_ACCESS 表示您提供了错误的指针。也许您未能正确保留 jokesArray？
