Hello, all ...
I'm experiencing a hang in my app when I do things too quickly. When
I pause the app and examine the callstack, I see this:
#0 0x31467b18 in semaphore_timedwait_signal_trap ()
#1 0x3145e984 in semaphore_timedwait_signal ()
#2 0x3145b104 in _pthread_cond_wait ()

Hello, all ...
My app is hitting this breakpoint, and I don't know what it means (and
there is no stack frame in the call stack that lives in my source, so
while I can make a good guess about where it's happening, i'm not 100%
sure). What n00b mistake causes this breakpoint to be hit?
Hello, all ...
I'm experiencing weird issues with addObserver / removeObserver. I
log when I add observers, as well as when I try to remove them, but I
sometimes (not always) get an exception when I remove an observer:

Hello, all ...
I've found a few leaks in my app using Instruments, and it works well,
but i've this message that appears in the console window when I run
the app under XCode, and i'm not sure how to find the cause:

Bill,
Alas, I found it 10 minutes after I posted the message *sigh* ... I
forgot the autorelease pool in my override of -
observeValueForKeyPath:ofObject:change:contet: ... the console message
is gone now :-)
Many thanks anyway, though!
Do this in your callback:
{
make sure _anything_ that happens in this KVO handler is
dispatched to the main thread in that way?

Hello, all ...
I've another n00b Cocoa question: How can I wait for a thread to
finish without depending on a flag that may be reset and set before
the thread i'm waiting for has time to check it? For instance, in
Win32 (i'm not saying Win32 is the best, it's just what i've the most

I want to alter how often NSURLConnection calls receivedData -- or
rather, I want it to call it more often (even with fewer bytes) vs
less often (with loads and loads of bytes). Can I do this with
NSURLConnection or some other CF class, rather than have to go down to
Hello, all ...
If a certain flag is set, my app needs to advance to the next item in
a list to process it when the previous item is done. However, I want
the user to still be able to stop it, so I don't want to hang the UI.
In effect, if this flag is set, I want the app to act as if the

Hello, all ...
I've another simple ObjC question that I hope someone can answer --
this has to do with memory management and NSMutableString. If I do
this:

I need to play an MP3 stream from a server in ObjC, so i'm looking at
the Audio Queue services API. I see examples of streaming from a
file, but I don't know how to feed the queue when i'm streaming from a
TCP port. Can someone point me to an example / tell me what API to
Stefan,
Though it's not ObjC, i've used gSOAP in several projects for SOAP
clients and servers. If you have a WSDL, it will generate either a C
or C++ interface (your choice) from it. Otherwise, it will generate
the WSDL given a header file that you define.

able to discuss them with others :-)
