Question

Swift里能不能把string转成字典或数组.就像解析json一样

Answer 1

和OC写法差不多；
利用NSJSONSerialization序列化成NSData,再通过NSString 转成JSON字符串
func toJSONString(dict:NSDictionary!)->NSString{

var data = NSJSONSerialization.dataWithJSONObject(dict, options: NSJSONWritingOptions.PrettyPrinted, error: nil)
var strJson=NSString(data: data, encoding: NSUTF8StringEncoding)
return strJson

}
