Hi Andy,
I'm still not familiar with the text system, so I don't know if the
proxy was a good way to do this.
But assuming it was, try implementing forwardingTargetForSelector:
instead of forwardInvocation:. It's less flexible, but much faster,
and your case doesn't require the flexibility.
Who liked to spit fire? :D
as I said do not use mach primitives, I will not dive into details
but it's one of worst advice you got here,
spawn + run code into an exception handler
do what you want with the result
Cheers!

Ooops, nevermind!!
I answered my own question.
When adding the class file to the project, start with the NSView
subclass template, then change it to subclass NSTextView in the .h
and in the .m either call [super drawRect:rect]; or comment out or
delete the drawRect method all together.

Hi,
Disclaimer: this is a question from a newbie.
Could someone please explain why an NSColor yields so much data when
archived to NSData?
For example, the following code:

I have model versions 1, 2, and 3, 3 being the latest.
Obviously I need a mapping file to upgrade 2 - 3.
But for upgrades of v1, should the mapping file be 1 - 3 direct, or 1
- 2 and Core Data will do a two-step upgrade?
The latter would be simplest, having Core Data automatically chain

I'm having a weird behavior with the bindings and core data.
i'm sure it's the way the bindings are set that causes my problem but
i can not find the answer.
so i'll ask you guy's :)

Clearly, there is a lot more going on in the code in this question
than in typical Cocoa code.
That said, if you want to avoid bugs, it would seem that the
following is good advice:
* Always use autorelease.
* Use an Auto Release Pool if necessary (in loops, or with large
memory
I have added a call to CFMakeCollectable each time after I create a CF
object like this
CFSomeTypeRef a = CFCreateSomeType();
if (a != nil)
{
CFMakeCollectable(a);
}
But I keep getting this runtime message in the console:
malloc: reference count underflow for 0x10773c0, break on
What does the stack look like when you break on
auto_refcount_underflow_error? After you break, you can do call
(void)CFShow(number goes here) with the number printed out in the
log message. That should hopefully give you the type of the object,
which might help you determine where the issue is.

In this case, you're not specifying the not shown attribute for the
