在Objective C中解析Plain JSON数组 [英] Parsing Plain JSON Array in Objective C

问题描述

我想解析一个简单的JSON数组，如：

I want to parse a plain JSON array like:

{
    "ns": [
        [
            "1364987475027",
            "Alert1",
            "001"
        ],
        [
            "1364987475042",
            "Alert2",
            "001"
        ],
        [
            "1364987475058",
            "Alert4",
            "001"
        ]
    ]
}

将数组放入简单的字符串数组中。我发现很多帖子都带有JSON字典数组。但在这种情况下，JSON没有值的键。
请帮忙。

To get the array in simple arrays of string. I found many posts with JSON dictionary arrays. But in this case the JSON is not having keys for the values. Kindly help.

推荐答案

答案： NSJSONSerialization 。

NSJSONSerialization 类可用于将JSON转换为Foundation对象，将Foundation对象转换为JSON。在您的情况下，您应该使用 -JSONObjectWithData：options：的 NSJSONSerialization 类来检索给定的Foundation对象JSON数据。

NSJSONSerialization class can be used to convert JSON to Foundation objects and Foundation objects to JSON. In your case, you should use -JSONObjectWithData:options:error: of NSJSONSerialization class to retrieve a Foundation object from given JSON data.

示例代码：

NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSArray *fetchedArr = [json objectForKey:@"ns"];
