解析Json以获取一个NSArray中的所有内容

Question

这就是内容......

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

如何将每个Feed源插入一个阵列？

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

我必须插入哪个键？ 感谢

因为我可以看到你的结构，你将摆脱这个JSON-String

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

所以你已经在root上有一个“Feeds”数组，你必须用数组中的索引来对它们进行迭代。对于第一个ID，即[[myJsonStructure objectAtIndex:0] objectForKey:@"id"];
