我有一个带有GIF横幅网址的字符串，我需要将其放入应用程序。

我的代码：

  func showAdd（）{
 Request.get（http://www.kyst.no/api/?apiMode=advertisement&lang=no，{（错误：NSError？，数据：NSData，文本：NSString？） - >（）in 
让jsonResult：Dictionary = NSJSONSerialization.JSONObjectWithData（data，options：NSJSONReadingOptions.MutableContainers，error：nil）as Dictionary< String，AnyObject> 
 var banner：NSString = jsonResult [advertisement]！[ banner] as NSString 
 self.addViewImage.image = UIImage.animatedImageNamed（banner，duration：1）
