objective-c - 如何在 Objective-C 中访问 NSMutableDictionary 的值？

Question

这是我的代码

NSMutableArray *responseArray = [responseString objectFromJSONString];

我想这样做来获取值：

NSMutableDictionary *responseDict = [responseArray objectAtIndex:<#(NSUInteger)#>];

我想添加NSMutalbeArray到 Dict 变量，如何做到这一点请帮助我

这是responseArray：

response >>>>>>>>> succ [{"id":"1","name":"Guitars \/

 Basses","description":"","image":"","parent_category":null},{"id":"2","name":"Keyboards \/ 

 Modules","description":"","image":"","parent_category":null},{"id" . . . . .  }]

如何获取字典值？

首先在http://jsonlint.com/上检查您的 json 响应。它是无效的。
