问题说明
我有一个用例，我有一个字典数组，我需要它们作为json对象：
I have a use case where I have an array of dictionaries and I need them as a json object:
var data = [Dictionary<String, String>]()
//append items
var bytes = NSJSONSerialization.dataWithJSONObject(data, options: NSJSONWritingOptions.allZeros, error: nil)
var jsonObj = JSON(NSString(data: bytes!, encoding: NSUTF8StringEncoding)!)
println(jsonObj)
println(jsonObj[0])
第一个打印声明给了我
[
{"price":"1.20","city":"Foo","_id":"326105","street":"One"},
{"price":"1.20","city":"Bar","_id":"326104","street":"Two"}
]
第二个
null
但我希望它能返回json数组中的第一个元素。我做错了什么？
but I would expect it to return the first element in the json array. What I am doing wrong?

根据文档，这应该是你所需要的。
According to the docs, this should be all you need.
var data = [Dictionary<String, String>]()
//append items
var jsonObj = JSON(data)
println(jsonObj)
println(jsonObj[0])
将数组直接转换为 JSON 对象时遇到问题吗？
Are you having a problem with converting an array directly into a JSON object?
