我正在关注来自web服务api的json响应.我想从json中提取产品数据.我还想使用AFNetworking实现这一点.

 {"products": [
    {
      "product_id": "1170",
      "name": "zzzz®",
      "sort_order": 0,
      "brand": "zzzas",
      "product_category_id": "1090",
      "location_ids": [
        "1078"
      ],
      "icon_url": "http://zzzzz.com/media/2502/zzzz.png",
      "icon_date": "Wed, 07 Nov 2012 14:03:47 GMT",
      "thumbnail_url": "http://zzzz.com/media/2591/zzdfs.png",
      "thumbnail_date": "Wed, 07 Nov 2012 14:04:02 GMT"
    },
    {
      "product_id": "1126",
      "name": "ddddd®",
      "sort_order": 1,
      "brand": "dddsas",
      "product_category_id": "1110",
      "location_ids": [
        "1095"
      ],
      "icon_url": "http://zzzzz.com/media/2507/ddddd.png",
      "icon_date": "Wed, 07 Nov 2012 14:03:48 GMT",
      "thumbnail_url": "http://zzzzz.com/media/2596/sssds.png",
      "thumbnail_date": "Wed, 07 Nov 2012 14:04:05 GMT"
    }

任何人都可以建议一种方法来完成这些.事情.

你好，我想提取 () 之间的文本。

例如 ：

(some text) some other text -> some text
(some) some other text      -> some
(12345)  some other text    -> 12345

括号之间的字符串的最大长度应为 10 个字符。

(TooLongStri) -> nothing matched because 11 characters

我目前拥有的是：

let regex   = try! NSRegularExpression(pattern: "\\(\\w+\\)", options: [])

regex.enumerateMatchesInString(text, options: [], range: NSMakeRange(0, (text as NSString).length))
{
    (result, _, _) in
        let match = (text as NSString).substringWithRange(result!.range)

        if (match.characters.count <= 10)
        {
            print(match)
        }
}

效果很好，但匹配的是：

(some text) some other text -> (some text) …
