问题
Currently, I'm trying to parse an NSData in my iOS app. Problem is, I can't seem to find a proper hebrew encoding for parsing. I must decode the data using the Windows-1255 encoding (hebrew encoding type for windows) or ISO 8859-8 encoding, or I'll get plain gibberish. The closest I've got to solving the issue was using
CFStringConvertEncodingToNSStringEncoding(CFStringEncodings.ISOLatinHebrew)
yet it throws 'CFStringEncodings' is not convertible to 'CFStringEncoding' (notice Encodings vs Encoding).
What can I do in order to encode the data correctly?
Thanks!
回答1:
The problem is that CFStringEncodings is an enumeration based on CFIndex
(which in turn is a type alias for Int), whereas CFStringEncoding is a type
alias for UInt32. Therefore you have to convert the .ISOLatinHebrew
value explicitly to a CFStringEncoding:
let cfEnc = CFStringEncodings.ISOLatinHebrew
let enc = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEnc.rawValue))

Turns out I needed to get my hands a bit dirty.
I saw that CFStringEncodings has a relation to the file CFStringEncodingsExt.h, so I searched the file for some help. Suddenly I came across a huge CF_ENUM that included exactly what I needed- all of the CFStringEncodings by their UInt32 value!
So it has turned out that kCFStringEncodingISOLatinHebrew = 0x0208, /* ISO 8859-8 */
I encourage everyone who is facing this encoding issue to go to that file and search for his needed encoding.
