【问题描述】：

我正在尝试调用网络服务并上传图片，

映射有问题，我花了好几个小时都没有成功。我得到的错误是：

错误域=org.restkit.RestKit.ErrorDomain 代码=1001 "不可映射在搜索的关键路径中找到了对象表示。” UserInfo={NSLocalizedDescription=没有可映射的对象表示在搜索的关键路径中找到。, NSLocalizedFailureReason=The 映射操作找不到任何嵌套对象表示在搜索的关键路径处：用户输入到发现映射器在以下关键路径：消息、成功这可能表明您为您的映射配置了错误的关键路径。keyPath=null, 详细错误=( )}

还有调用网络服务的方法

【解决方案1】：

此错误告诉您user 路径上没有可用的内容。例如，如果您的响应是 JSON，则不会有名为 user 的根键，只有 message 和 success：

{ "user": "<- This key doesnt exist", "message": "<- There is something here", "success": "<- There is also something here" }

您很可能需要将您的 keyPath 从 user 更改为 success.user。
