You can tell it to ignore the warning like this:
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
NSNumber *status = [ self performSelector: aSelector withObject: a

Hope that helps.

What reason is there for the documents to have a strong reference to the

No, this pipe/fork/dup2/exec is used in App Store apps - iSSH is an example as
it used its separate PuTTY executable. Maybe straight fork() is not available
but is there some replacement like posix_spawn()? iOS itself need some sort of
mechanism to fork/exec or there will be no apps.

Actually, the library doesn't create functions, just executable bi
No fork() on iOS and the GNUStep version of NSTask uses fork(), so that's not
going to work.
Apart from that, if you've built the library, you just call the functions.

1) You can use the NSTask implementation from GNUstep, an LGPL-licensed library.
2) You can still use classic UNIX function calls to pipe/fork/dup2/exec

Import the headers and call the functions, if you're linking your application
against it.

Ok, I figured it out. I was able to build three different static libraries for
armv7, armv7s and i386 and combined them with lipo into one that I added to my

The question now is, how do I call the functions in this library?
On the command line, I need to do something like this:

After modifying a Core Data document-based OS X app, it no longer autosaves
when quit. I need to fix that so it autosaves again.
Because my app is unfortunately complicated, I'm instead trying to understand
how autosave works when quitting a normal app. Here is what I did:

I’ve just gotten a nasty bug report involving an iOS app hanging when it goes
into the background. The problem is a deadlock involving NSCache. I can see
what the problem is, but I don’t know what to do about it.
In a nutshell: An NSCache is evicting objects, and as a result of that its last

Yeah, I though about that as well, and am going to try that. It comes with
makefiles for Mac (OSX only though), so I'll start with that.

Hi,
I have a custom subclass of NSTableView in my app.
I would like to change the highlight colour displayed when the user clicks on a
row, and have the colour maintained when the NSTableView subclass loses focus.
I have changed the subclass to ensure that the table is never first responder,
