我正在尝试调用网络服务并上传图片，
映射有问题，我花了很多时间都没有成功。我得到的错误是:
Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 "No mappable object representations were found at the key paths searched." UserInfo={NSLocalizedDescription=No mappable object representations were found at the key paths searched., NSLocalizedFailureReason=The mapping operation was unable to find any nested object representations at the key paths searched: user The representation inputted to the mapper was found to contain nested object representations at the following key paths: message, success This likely indicates that you have misconfigured the key paths for your mappings., keyPath=null, DetailedErrors=( )}
还有调用网络服务的方法

最佳答案
此错误告诉您 user 上没有任何可用信息小路。例如，如果您的响应是 JSON，则不会有名为 user 的根 key , 只有 message和 success :
{
"user": "<- This key doesnt exist",
"message": "<- There is something here",
"success": "<- There is also something here"
}
您很可能需要更改您的 keyPath来自 user类似于 success.user .
