To see CFNetworkErrors, go to CFNetwork.CFNetworkErrors

CFNetworkErrors.cfurlErrorDataNotAllowed.rawValue (Int32 value = -1020)

case cfurlErrorBadURL = -1000
case cfurlErrorTimedOut = -1001
case cfurlErrorUnsupportedURL = -1002
case cfurlErrorCannotFindHost = -1003
case cfurlErrorCannotConnectToHost = -1004
case cfurlErrorNetworkConnectionLost = -1005
case cfurlErrorDNSLookupFailed = -1006
case cfurlErrorHTTPTooManyRedirects = -1007
case cfurlErrorResourceUnavailable = -1008
case cfurlErrorNotConnectedToInternet = -1009
case cfurlErrorRedirectToNonExistentLocation = -1010
case cfurlErrorBadServerResponse = -1011
case cfurlErrorUserCancelledAuthentication = -1012
case cfurlErrorUserAuthenticationRequired = -1013
case cfurlErrorZeroByteResource = -1014
case cfurlErrorCannotDecodeRawData = -1015
case cfurlErrorCannotDecodeContentData = -1016
case cfurlErrorCannotParseResponse = -1017
case cfurlErrorInternationalRoamingOff = -1018
case cfurlErrorCallIsActive = -1019
case cfurlErrorDataNotAllowed = -1020
case cfurlErrorRequestBodyStreamExhausted = -1021
case cfurlErrorAppTransportSecurityRequiresSecureConnection = -1022
case cfurlErrorFileDoesNotExist = -1100
case cfurlErrorFileIsDirectory = -1101
case cfurlErrorNoPermissionsToReadFile = -1102
case cfurlErrorDataLengthExceedsMaximum = -1103

The error codes you get from NSURLConnection are in NSURLError.h and CFNetworkErrors.h, as well as this Apple documentation. It looks like -1020 is kCFURLErrorDataNotAllowed, which says:

"The connection failed because data use is currently not allowed on the device."

Surprisingly, I can not see the error code -1020 there.:(. 

typedef enum
{

   NSURLErrorBadServerResponse = -1011,

   NSURLErrorUserCancelledAuthentication = -1012,

   NSURLErrorUserAuthenticationRequired = -1013,

   NSURLErrorZeroByteResource = -1014,

   NSURLErrorCannotDecodeRawData = -1015,

   NSURLErrorCannotDecodeContentData = -1016,

   NSURLErrorCannotParseResponse = -1017,
}

I believe that this one is a right table right?
