Hi all,
Thanks for your reply. I didn't retain that, I will try that as soon
as I
get home.
Anyway, why I should retain that? Will it be released by "somebody"?
Re-read the Memory Management Programming Guide until you know the
rules backwards and forwards. +dictionaryWithObjects:forKeys: doesn't
start with "alloc," "new," or "copy," so you don't own its return value.
Can
anyone tell me the whole process and what's going on please? I want
to know
what happened. Thanks a lot.
This shouldnt be necessary once you reread the documentation. But in
order to do that, you would need to post your code in context, which
you should always do for every question you ask. Out of context, what
you posted is neither wrong nor right.

However, I declare a NSDictionary instance variable in my model

Are you retaining that?
- (id)init {
if (self = [super init]) {
// assuming you have an ivar called "dict", this will lead to the
problem you define:
dict = [NSDictionary dictionaryWithObjects:names forKeys:keys];
