I didn't think about NSValue, thanks.
Do you mean valueWithPointer?

Not a really elegant solution but I can understand that those
containers require pointers.
Now I need to create a NSMutableArray of CGPoint, how can I make it
became a pointer?

I just realized valueWithPoint is not available on the iPhone SDK and,
I can't understand why, it can't be discussed here. Both things of
course suck! :)
Thanks a lot, chr

well can you manage the lifetime of the CGPoints well enough to use
valueWithPointer: which, if I read it correctly, doesn't free the
pointer when it's done? Or just write your own NSObject derivation you
can pass a CGPoint to, by value and have it copied, or as a pointer,
but which it

It's just a convenience method for something like:
[NSValue valueWithBytes:somePoint objCType:@encode(NSPoint)]
You can implement this yourself in a
Yep, this should work as well.
Thanks, chr

Should be:
NSPoint somePoint = NSMakePoint(x,y);
[NSValue valueWithBytes:somePoint objCType:@encode(NSPoint)];

What's wrong with +[NSValue valueWithCGPoint:CGPointMake(x, y)] ?

CGPoints and NSPoints have the same structure so you can

You shouldn't really. You should use NSPointFromCGPoint/
NSPointToCGPoint. Their implementation is in NSGeometry.h and is not a
simple cast.
NSPoint and CGPoint may be the same
