Re: Feeding NSUnarchiver bad data can cause crash

Jeremy,

When you say, "it doesn't work" do you mean that an exception not thrown OR
do you mean that your code did not do what it was supposed to do?

I mean that the exception isn't thrown. The unarchiver still crashes the app. I get exactly the same behaviour with the handler placed in a home-made -canBeUnarchived: method as you described:

- (BOOL)canBeUnarchived:(NSData *)Target_Data
{
id archive;
BOOL success = NO;

NS_DURING
archive = [NSUnarchiver unarchiveObjectWithData:Target_Data];
success = YES;
NS_HANDLER
success = NO;
NS_ENDHANDLER

return success;
}

It still crashes when the bad data is unarchived.

Regards,
-Jeremy
