使用RestKit POST請求圖像

Question

我試圖從服務器接收使用POST請求的圖像。我正在嘗試使用RestKit獲取圖像。我添加了用於創建請求的請求描述符，它工作正常。但是，我不明白如何映射圖像與對象管理器，因爲返回的內容不再是JSON。

這裏是我得到

Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 "No mappable object representations were found at the key paths searched." UserInfo=0x9b7a870 {DetailedErrors=(

你不應該使用RestKit此錯誤。 RestKit旨在用於從JSON/XML/...映射對象...它並不意味着接收圖像數據。相反，使用包含在RestKit中的AFNetworking（用於所有通信的內部），並且可以更好地處理簡單的帖子和圖像響應。

如果你需要做一些對象序列化來創建JSON來做你的文章，然後看看使用RKSerialization和RKMapperOperation。
