Dear list,
I have a document based app which has a number of per-document background tasks
fired off timers. After moving from GC to ARC the app was suffering from
crashes when closing documents due to the referencing of deallocated objects.
So I've gone through the whole app and implemented -t

Your pattern can fail if this line
_someDictionary = temp;
isn't atomic.

I have seen exactly this problem with the audio data property of AVAudioPlayer
- but it only seems to happen in simulator. On the device the data does does
get released correctly when the AVAudioPlayer instance is deallocated. I am
using ARC. I spent half a day making sure the data was no

It's not directly what you need, but NSLogger might be worth looking
at. It sends realtime logs from an iOS device to the desktop:

I know, but Apple's own Help Book icons all seem to be 64x64, which is 4x the
size (in each dimension), not 2x, which is why I'm confused.
Is there any
Yes I understand, I use NSInputStream and NSOutputStream for writing something
but I don't know why I have my stream closed after an event hasSpaceAvailable

Hi,
I am getting serious difficulties at drawing an attributed string within an
attachmentCell and get it aligned on the baseline.
I have a NSTextView. I add an attachment with its attachmentCell.
In the method cellFrameForTextContainer I return a

Top advice - and one step closer. I now have help in English and in Spanish.
Sadly, my French help is also in Spanish - which is rather confusing!
