But now I'm confused about how to de-allocate MyClass. Given this in
its initialisation:
S1 = @"a string";
S2 = [[NSString alloc] init];
S3 = [NSString string];
I would only release S2 in the dealloc method. But if the class has
been unarchived, won't I leak memory with S1 and S3 when the class
is released?
An approach that might help clarify this is to have accessor methods
to set each string, rather than assign them directly in the
initWithCoder method. Then you can write something like:
[self setFirstString:[coder decodeObjectForKey:@"blah"]];
then there's no special case when dearchiving compared with setting
the string from any other place. And of course, the accesssor method
would, as is the norm, retain the object.
Sending -retain to a constant literal string is fine, so you don't
need to treat those as a special case either. So again:
[self setFirstString:@"Initial Value"];
is fine, even if the -setFirstString method retains the string, as it
should.
