如何显示来自FBgraph API的错误消息

Question

I'm using FBgraph API and now I want to print Error message in a single line like

(#341) Feed action request limit reached

Below are the response from FBgraph API:

Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x6b273c0 {error=<CFBasicHash 0x6b26560 [0x1c91b48]>{type = mutable dict, count = 3,
entries =>

    3 : <CFString 0x6b26930 [0x1c91b48]>{contents = "message"} = <CFString 0x6b268d0 [0x1c91b48]>{contents = "(#341) Feed action request limit reached"}
    6 : <CFString 0x6b271d0 [0x1c91b48]>{contents = "code"} = 341
}
}

Please Help.

I believe the request carries 3 different types of error message you can read. Error [Error localizedDescription] [Error description]

One of these might give you the line you want.

Oh, there's also [error userinfo]
