我得到了 NSDictionary

Printing description of gameDict:
{
    result =     {
        developer = "Bethesda Game Studios";
        genre = "Role-Playing";
        name = "The Elder Scrolls V: Skyrim";
        platform = "PlayStation 3";
        publisher = "Bethesda Softworks";
        rating = M;
        rlsdate = "2011-11-11";
        score = 92;
        summary = "The next chapter in the Elder Scrolls saga arrives from the Bethesda Game Studios.

}

只有一把钥匙"result" 我怎样才能得到其他钥匙？

Answer 1

gameDict 是一个带有 key/pair 的 NSDictionary。键 "result" 指向另一个有更多键的 NSDictionary。因此，要访问任何更深的键，您可以内联进行：

NSNumber *score = gameDict[@"result"][@"score"];

或者你也可以把字典拿出来查询

NSDictionary *resultDict = gameDict[@"result"];
NSNumber *score = resultDict[@"score"];
