Does ist help, if you assign it this way instead:
self.context = theContext;
In your original code you're directly accessing the backed instance variable
instead of going over the property, so maybe your property-declaration is
ignored in this case.

Hi,
Has anyone else noticed that Placeholder text in UITextFields's is very dim
in iOS7? It looks ok in iOS 6, but in 7 it can hardly be seen?
I found this hack:
the pointer value for the save panel never changes, but the object it points
to has some serious changes of identity.
For me this sounds like an overrelease or access after release problem.
You could try to run with enabled zombie objects.

Hi,
when using UIDocument, reading and writing the document is done asynchronously
in a separate thread. But there's one thing I don't understand: how is that
supposed to be used with non-thread-safe models? In my opinion most
straight-forward implemented models are _not_ thread-safe.

Hi,
is there a file path to the console output - visible in Xcode, e.g. when
calling NSLog, I think it's stderr - on the iPhone?
I tried /dev/stderr or /dev/fd/2 (and several other paths) but they do not
work and if I get the directory contents of /dev they really don't exist on
iOS.
stdout
From OS/X man pages and I'm thinking this probably works as well on iOS
That's what I thought, too. But unfortunately it doesn't work.
So e.g., stdout would be /dev/stdout. See if that works for you...
Does not work. I tried that:
[@\n\nTEST\n\n\n writeToFile:@/dev/stdout
Background: I have a third party library (that I am not allowed to change)
that logs to a file in Debug mode. I want to see this log output directly
in the Xcode console, because transferring log files from the iPhone is too
complicated. The library provides an API to set the file path

Maybe the file is corrupt. In most cases it can be solved by deleting the
XML file and then making a slight change in iTunes (e.g. rename a song). The
file is then written again soon and should be fine.
Yeah, it’s a strange problem because this file gets rewritten from scratch

Are you sure you are _not_ calling drawRect yourself, but let the system call
it when needed?
If a view needs to be redrawn, the system sets up
- (void)drawRect:(NSRect)rect {
[...]
[img drawInRect:rect ...];
}
Not related to your original problem, but please note that the NSRect passed to
drawRect is the dirty area that needs to be redrawn. In many cases this matches
self.bounds, but not always. So using this rect as

I think in the line when going down the recursion, you have to assign the

The problem is that when you call swapcontext() to switch the user-thread

Still, CGFloat is a pain when using the 64 to 32 bit truncation warning

You probably shouldn't be putting up a modal dialog from within the
menu-tracking runloop mode. You can use -
performSelector:withObject:afterDelay:inModes: to defer the call
that opens the modal dialog; use a delay of 0.0 but a modes array
that includes only the default runloop mode.
I have a modal dialog window that pops up at some time. I am doing
the modal session with [NSApp runModalForWindow:window].
If the user has clicked into the menu bar just before this modal
window opens, the menu is hanging down and can not be closed before
the modal window is closed.
