在 Swift 语言中更好的处理 JSON 数据:SwiftyJSON

分享到:

SwiftyJSON能够让在Swift语言中更加简便处理JSON数据。

With SwiftyJSON all you have to do is:

let json = JSONValue(dataFromNetworking)
if let userName = json[0]["user"]["name"].string{
//Now you got your value
}

And don't worry about the Optional Wrapping thing, it's done for you automatically

let json = JSONValue(dataFromNetworking)
if let userName = json[999999]["wrong_key"]["wrong_name"].string{
//Calm down, take it easy, the ".string" property still produces the correct Optional String type with safety
}
let json = JSONValue(jsonObject)
switch json["user_id"]{
case .JString(let stringValue):
let id = stringValue.toInt()
case .JNumber(let numberValue):
let id = numberValue.integerValue
default:
println("ooops!!! JSON Data is Unexpected or Broken")

Error Handling

let json = JSONValue(dataFromNetworking)["some_key"]["some_wrong_key"]["wrong_name"]
if json{
//JSONValue it self confirm to Protocol "LogicValue", with JSONValue.JInvalid produce false and others produce true
}else{
println(json)
//> JSON Keypath Error: Incorrect Keypath "some_wrong_key/wrong_name"
//It always tells you where your key starts went wrong
switch json{
case .JInvalid(let error):
//An NSError containing detailed error information
}
}
