解析Json以获取一个NSArray中的所有内容 [英] Parsing Json to get all the contents in one NSArray

问题描述

这就是内容......

That's the content...

[
    {
        "id": "",
        "title": "",
        "website": "",
        "categories": [
            {
                "id": "",
                "label": ""
            }
        ],
        "updated": 
    },
    {
        "id": "",
        "title": "",
        "website": "",
        "categories": [
            {
                "id": "",
                "label": ""
            }
        ],
        "updated": 
    }
]

如何在一个数组中插入每个Feed源？

How can I insert every feed source in one array?

 NSDictionary *results = [string JSONValue];
NSArray *subs = [results valueForKey:@"KEY"];

我必须插入哪个密钥？
谢谢

Which key I must insert? THanks

推荐答案

因为我可以看到你的结构，你将摆脱这个JSON-String

as I can see your structure, you will get out of this JSON-String

NSArray:
[
    NSDictionary:
    {
        NSString: "id",
        NSString: "title",
        NSString: "website",
        NSArray:  "categories": 
        [
            NSDictionary:
            {
                NSString: "id",
                NSString: "label"
            }
        ],
        NSNumber: "updated"
    },
    NSDictionary:
    {
        ...
    }
]

所以你已经根目录中的Feeds数组，你必须使用它们中的索引来对它们进行迭代。对于第一个id，即 [[myJsonStructure objectAtIndex：0] objectForKey：@id];

So you have already an array of "Feeds" at root and you have to itterate them with their index in the array with. For first id i.e. [[myJsonStructure objectAtIndex:0] objectForKey:@"id"];
