Hello
I have a thread A that spawns a thread B, and should stop, waiting
before the thread B allows thread A to continue.
In Windows, in a thread A, before spawning a thread B, i would create
a synchronization "Event" primitive in the "non signaled" mode, the
spawn a thread B, and call WaitForSing
Try NSConditionLock. Its documentation should be pretty self-explanatory.

Health,
thanks for the response.
However, i can't see how can i use NSConditionLock in my situation.
For every lock (or mutex/semaphore - which essentially is the same) i

Dear Fritz and all,
I am reading one book, Daniel H Steinberg, Cocoa Programming, A Quick-Start
Guide for Developers, 2010. Chapter 26 introduces Dispatch Queues. It

Leopard or earlier, you're out of luck."

Yes: blocks and GCD are in iOS 4.

Only thing I can think of is self.nothingButton == nil.

I was finally able to get it to "work".
As others have pointed out, and rightfully so, there be dragons here.
The following all constitutes godawful hacks and abuse of the system.
I'm gonna file a feature request that services should be configurable

Hi,
A singleton can be a good option for your shared data as suggested by
many people over here.
However, if you dont want a singleton, you can setup the Application
delegate as the data holder.
since application object can be accessed from anywhere in the app, you
can thus access your Arra

Still not sure how would it be possible to do using NSConditionLock,
but i managed to do it using NSCondition :)

To add further to the brittleness (or non-functionality, if you prefer - it's a
sliding scale), this will fail on any system set to use a non-Englis

Hang on. Why use a thread at all? If Thread A simply calls the process B
synchronously, it will achieve exactly what you have state
Hi,
I have a singleton class that manages a tableView (and provides the datasource).
Now I would like to update this tableView from another class.
Since the class that manages the tableView is a singleton I don't have to
initiate a new instance of that class.
So I thought there should be no pro

Check NSBezierPath usage. A message like that shows up when -relativeXXX is

Thanks for all the replies,
I will check my NSBezierPath code to see if I'm doing anything of that sort,
but like I said, this only happens on 10.6.7. And Kyle, indeed the only code of
mine that is in the stack trace is NSApplicationMain(). The stack trace
confirms this:
thread #1: tid = 0x2d0

Maybe because some additional asserts/sanity checking was added in 10.6.7. It
doesn't mean the bug isn't there on earlier OS, it just means it was keeping
quiet about it.

I have gone through and checked my code to make sure that I wasn't doing the
things you mentioned earlier with NSBezierPath. This is a real pain to solve
seeing as the debugger isn't giving me a single shred of useful information.

I'm assuming it is, because as soon as I click "Continue" after it breaks, the
message is logged. Once the message has been logged once, the entire window
stops responding and any attempt to click on anything will just result in the
message being logged over and over again.
