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?
