我是靠谱客的博主 风趣鸭子,这篇文章主要介绍Swift中字典与JSON转换的方法,现在分享给大家,希望可以做个参考。

Swift中经常会遇到字典和字符串的相互转换,因此可以转换可以封装起来,转换代码如下:

func convertStringToDictionary(text: String) -> [String:AnyObject]? { if let data = text.data(using: String.Encoding.utf8) { do { return try JSONSerialization.jsonObject(with: data, options: [JSONSerialization.ReadingOptions.init(rawValue: 0)]) as? [String:AnyObject] } catch let error as NSError { print(error) } } return nil } func convertDictionaryToString(dict:[String:AnyObject]) -> String { var result:String = "" do { //如果设置options为JSONSerialization.WritingOptions.prettyPrinted,则打印格式更好阅读 let jsonData = try JSONSerialization.data(withJSONObject: dict, options: JSONSerialization.WritingOptions.init(rawValue: 0)) if let JSONString = String(data: jsonData, encoding: String.Encoding.utf8) { result = JSONString } } catch { result = "" } return result } func convertArrayToString(arr:[AnyObject]) -> String { var result:String = "" do { let jsonData = try JSONSerialization.data(withJSONObject: arr, options: JSONSerialization.WritingOptions.init(rawValue: 0)) if let JSONString = String(data: jsonData, encoding: String.Encoding.utf8) { result = JSONString } } catch { result = "" } return result }
