我正在使用swift在Xcode 6中處理iOS應用程序。我對這門語言很陌生，說實話，我正在拿出我有的小發型。在Swift中解析JSON不起作用
我要看到我的API調用LastFM等下面的JSON結果usingb的NSLog時（ 「％@」，allResults）

我有一個試過如下：
func didRecieveAPIRequest(results, NSDictionary) {
let results: NSArray = results["artist'] as NSArray
我得到一個EXC_BREAKPOINT拋出並崩潰。所以嘗試了字典路線，我可以看到數據。事實上，我可以得到這個名稱和生物，但我無法訪問特定的圖片網址。我認爲它與嵌套有關，但是在這個時候我感到很茫然，因爲它可以調用Itunes API。它可能是一個新秀的錯誤，但和幫助將不勝感激。
讓我知道是否需要更多信息，並且請只提供建設性答覆。
在此先感謝。
如果您的「內容」值的長度是不相關的，有關eliding怎麼了？ – GoZoner 2014-12-13 18:23:03
