SwiftyJSON能夠讓在Swift語言中更加簡便處理JSON數(shù)據(jù)。

With SwiftyJSON all you have to do is:

?

1 2 3 4

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

?

1 2 3 4

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 }

?

1 2 3 4 5 6 7 8

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

?

1 2 3 4 5 6 7 8 9 10 11 12

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 ??} }
