我想快速创建一个像这样的json:
{ "test1": 0, "test2": 1435659978, "test3": 1430479596 }
如何创建此json?
创建您的对象,在这种情况下为字典:
let dic = ["test1":0, "test2":1435659978, "test3":1430479596]
从对象创建JSON数据:
do { let dic = ["test1":0, "test2":1435659978, "test3":1430479596] let jsonData = try NSJSONSerialization.dataWithJSONObject(dic, options: NSJSONWritingOptions.PrettyPrinted) } catch let error as NSError { print(error) }
如果需要,请使用JSON数据作为字符串:
do { let dic = ["test1":0, "test2":1435659978, "test3":1430479596] let jsonData = try NSJSONSerialization.dataWithJSONObject(dic, options: NSJSONWritingOptions.PrettyPrinted) let str = String(data: jsonData, encoding: NSUTF8StringEncoding) } catch let error as NSError { print(error) }
