just wondering what causes the retain count of an object to drop.
this is the situation I've been wondering about:
NSString *myString = [NSString stringWithFormat:@"testing"];
myString = anotherString;
when I point myString away from the 'testing' string, does the
'testing' memory get freed?
or should I release myString before pointing it to something else?
also, in this situation do I now have two pointers to the same piece
of memory, and therefore a retain count of two?
That statement has no effect on retain counts or freeing of memory. The
only something gets retained is if it is sent a retain message, the
only way something gets released is if it is sent a release or
autorelease message.
