I am trying to build my own version of NSKeyed(Un)Archiver.
But I do not know how to recognise mutability.
1. use isKindOfClass: [NSMutableString class]
disadvantage: all strings turn out to be mutable
2. use respondsToSelector: @selector(appendString:)

Hello,
I'm implementing the Drag and Drop functionality over the same Custom View. My6
Custom is acting as source and Destination. I've implemented it according to
Apple's Guideline for Drag and Drop wit Custom Views. I've started the Drag and
Drop from mouseDown: event.
Normally it works

If you upgraded to Xcode 4.6 and suddenly you've been seeing crashes when
deploying to Snow Leopard, you might want to go back to Xcode 4.5.2.
In a nutshell, the following crashes on 10.6.8 when compiled with Apple LLVM
4.2 with a deployment target of 10.6.
NSArray *array = [[NSArray
Is it the empty array that's causing the crash? Does it still crash if
the array has at least one object?

Looks like every pipe is leaking. I cannot see a way to prevent the leak myself
as I know the NSPipes are being released. It doesn't seem to crash with Auto

I take that back, it still crashes with ARC… It crashes at run 4720.

Hi all
Is there a way to feed an NSTask argument data when the command line tool in
the task expects a file path argument?
I would like to not actually create a file to use as the argument, but rather
send data that would be in said file.
Can this be done via NSFileHandle or NSPipe from

Just call -setStandardInput: and pass /dev/stdin as the filename
