Greetings
I'm having problems unarchiving my data in the iphone.
here is the workout.
1: I archive a AttributedString to my CoreData NSData property using
NSKeyedarchiver
2: Transfer the database to the iphone.
3: load the data using NSKeyedUnarchiver on the iphone.
NSAttributedString *as = (NSAttributedString*)[NSKeyedUnarchiver
unarchiveObjectWithData:attributedStringData];
that crashes saying:
-[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (NSFont)
I understand that the NSFont is UIFont on the iphone, or has similarities.
so i implemented a Delegate method to replace the class.
//------------------------------------------------------------------------------
- (Class)unarchiver:(NSKeyedUnarchiver *)unarchiver
cannotDecodeObjectOfClassName:(NSString *)name originalClasses:(NSArray
*)classNames{
if ([name isEqualToString:@"NSFont"])
return [UIFont class];
return nil;
}
but that never gets called because the class method does not allow for a
delegate and instantiating the unarchiver class confuses me in how I should
trigger the decoding once it is instantiated.
Any pointers ?
Sandro Noel.
