You want to go one level deeper than the NSData stuff that's
provided and override the following methods:
- (BOOL)readFromFile:(NSString*)filename ofType:(NSString*)docType
- (BOOL)writeToFile:(NSString*)filename ofType:(NSString*)docType
- (void)close
Replace them with code that opens and closes your archive/whatever.
My readFromFile method simply connects to the database. My
writeToFile method does nothing (but return YES) because I never
"write" the document. Close your file in the close method.
I also provide implementations of
- (BOOL)readFromURL:(NSURL*)url ofType:(NSString*)type
- (BOOL)writeToURL:(NSURL*)url ofType:(NSString*)type
which simply call readFromFile and writeToFile. I don't know if
this is necessary, but it lets me sleep at night.
This makes sense. I will definitely take a look at it today. Thanks
for your insights :)
