Further experiments show that some disks can be ejected under sandbox,
while others cannot. For example, CD, USB sticks, DMGs and some
external drives can be ejected/unmounted, while other external drives
and internal partitions cannot. The rule isn't that simple and seems
to have many exceptions.

I want to get a file from a server into my iPad App.
If I do http://... it launches Safari.
I just want the file … what is the proper way to do this?

Are you us
Steve,
Can you run an NSOpenPanel with a completion handler block, and in that block,
call a method on a background thread to actually perform the file read
operation?
As a test, I put this together. I called the selectAFile method and chose a 4GB
text file. The open panel was dismissed after

Possibly because they predate IBAction? IB used to just look for methods
that took an id argument and returned void.

Is there some reason why some classes, such as NSTextView, don¹t declare
IBAction in their actions? I¹ve taken to re-declaring such in subclasses,
which works, but results in compiler warnings about unimplemented methods.
Without that, you can¹t connect, say, a menu, in IB. You can use a binding,

You open a system header from the SDK into XCode, and due to muscle-memory,
absent-mindedness, reflex, lack of context or whatever, you hit cmd-S and save
it over the old header (even if it hasn't actually been changed). XCode then

Thanks for all the input. I solved it by using a straightforward C-array,
which I think also circumvents the scenario that Conrad describes about the
crash being caused by index 3 being set before index 2.
As it turns out, the time for the whole loop *decreased* by 5-10 fold by using

Hello,
I am using Core Data to store a hierarchy of objects.
These objects are displayed in an NSOutlineView and their names are used to
populate a list of strings used in autocomplete.
Once my window loads I can see the hierarchy of objects displayed but if I try
to access them programmatica

NSMutableArray isn’t thread-safe. You’ll need to synchronize/serialize the

Hi,
I'm trying to use a queue for a calculation intensive for-loop to make my iOS
app more responsive. The original for-loop works without errors:
for (NSUInteger i = 0; i < count; i++)
{
myArray[i] = [self doCalculation: i];
}
When count gets too large, there is a delay when the resu

I've run across an unexpected and undocumented problem, and couldn't
google anything on it.
It seems that if an app is sandboxed, it is not permitted to eject
disks or unmount volumes.
I tried -[NSWorkspace unmountAndEjectDeviceAtPath:],
