I thought i had read that NSNumber knew how to code itself in an
NSArray... is this not the case? or is this code below just set up
all wrong? and what would the proper way be to set this up?
bookMarkNode's coders are below, this object has the one NSNumber,
and two NSStrings....
when i look in the debugger at "allItems", the NSNumber is not well
defined.
thanks in advance,
Jon.
BookMarkNode *node1 = [[BookMarkNode alloc] init];
[node1 setTypeOfLeaf:[NSNumber numberWithInt:0]];
[node1 setNodeTitle:@"eBay"];
[node1 setURL:@"http://www.ebay.com/";];
........etc.......
NSArray *allItems = [NSArray arrayWithObjects: node1, ..etc....
nil];
[node1 release];
//
-------------------------------------------------------------------------------
- (NSArray*)mutableKeys
{
NSArray *tempKeys = [NSArray arrayWithObjects:
@"typeOfLeaf",
@"nodeTitle",
@"urlString",
nil];
return tempKeys;
}
//
-------------------------------------------------------------------------------
- (id)initWithCoder:(NSCoder*)coder
{
self = [self init];
NSEnumerator *keysToDecode = [[self mutableKeys] objectEnumerator];
NSString *key;
while (key = [keysToDecode nextObject])
[self setValue:[coder decodeObjectForKey:key] forKey:key];
return self;
}
//
-------------------------------------------------------------------------------
- (void)encodeWithCoder:(NSCoder*)coder
{
NSEnumerator *keysToCode = [[self mutableKeys] objectEnumerator];
NSString *key;
while (key = [keysToCode nextObject])
[coder encodeObject:[self valueForKey:key] forKey:key];
}
