Is there any way to convert error enums into readable strings?
For example, the NSXMLParser might give me parse error number 76,
and I have to go look that up to find that that corresponds to
NSXMLParserTagNameMismatchError. Not very helpful for users who
don't have the NSXMLParser.h header file...
I suppose I could produce my own switch statement to produce an
error string for every NSXMLParserError enum value, but is there a
better way?
Not knowing of a built-in way to do this, may I suggest using
a .plist file to contain a dictionary that maps error numbers to
strings? These are easy to load as resources and keep in static
globals at +initialize time. A method that wanted error 76 would then
convert it to @"76" and pass it in objectForKey:.
A clever regular-expression replace (or BBEdit text factory) could
probably convert the enum listing to rough-cut message strings.
