The short answer is in 10.6.
The longer answer is that
I have a nib file set up in Interface Builder with a window containing a single

Technical Q&A QA1361
Detecting the Debugger
Does this code report on my app being debugged by any third party,
even when the app has been stripped of symbols ?
Would it work irrespective of the debugging tool used ?

Is there any way to tab into an NSBrowser in 10.4? It seems that once the
browser loses focus, you can't get focus

It does precisely what it claims to do: asks the kernel if the
P_TRACED flag is set on your process, which means a debugger

Hi all, I'm having a problem adding the appropriate objects to an

probably need to set this by hand, but I'm having issues.

I've created a subclass of NSTextFieldCell that just adds the

Modify the model, not the controller.
so the model object that holds the array should be called with
mutableArrayForKey:
passing the array variable key.
then mutate the array you get back.. that will be KVO compliant and the changes
will be reflected in your controller, and then your view.

You don't own any of those objects so you should not be releasing them.

I have a class set up, and in the header file, I have instances of NSString

use...(why they are declared in the header file). when i create an instance of
the class to use I have a problem.
I create one instance
Ahhh, thank you, that helped! What I did was add an NSArray property
(though it could've been NSMutableArray), then called setValueForKey,
and bound the ArrayController to that array. And it works great.

hi.
I have a window with 3 comboboxes. one of them uses a data source. the problem
is that it keeps throwing an exception, and i can't find out why. I've put the
following methods in my appcontroller:
-(NSInteger)numberOfItemsInComboBox:(NSComboBox *)aComboBox {
return (NSInteger)[symbol
what does the symbols array contain? are you sure it’s the length you think it
is? and what is index? It says −1 or possibly larger.
