Re: about memory

In using NSOpenPanel, do we need to call alloc and dealloc?

Nope. As for dealloc, but for the [super dealloc] in dealloc itself, you NEVER EVER call it.

NSOpenPanel *panel = [[NSOpenPanel alloc] init]

Wrong.

panel = [NSOpenPanel openPanel];

Right.

[NSOpenPanel dealloc]

Very very definitely wrong. Not only you never ever send dealloc explicitly; also, you don't send (in this context) message to a class, but to the instance.

NSOpenPanel *panel = [NSOpenPanel openPanel];

That's it.

Thank you very much ( as my concept on cocoa memory management is not so good

Why not reading the docs, and perhaps some of those so many articles on Stepwise?
