RestKit - 嵌套對象映射失敗，如果嵌套值是一個域名

我需要幫助嵌套對象映射，我想我碰到一個錯誤。RestKit - 嵌套對象映射失敗，如果嵌套值是一個域名

當嵌套值是一個域（something.com）時，restkit將它替換爲嵌套屬性並嘗試查找「something.com.name」，「something.com.url」，「something.com.email 「，假設2個嵌套，」東西「和」com「，因此失敗。

這裏是映射失敗的日誌：

您可以發佈您RestKit映射代碼爲這個對象？ – danielM

你不能（至少在寫作的時候）使用addAttributeMappingFromKeyOfRepresentationToAttribute對於相關包含點的數據，因爲該數據後來被用作一個鍵和點將其改變爲一個鍵路徑。這就是發生關鍵路徑導航錯誤的原因。

2個潛在選擇：

更改JSON
編輯RestKit不使用數據作爲的keyPath（只是一個鍵，所以valueForKey:）

是的，你是對的。我發現了幾個關於restkit的pull請求可以解決這個問題，但是暫時我說服了api所有者去改變它。 – jturolla
