Re: Identifying a specific Mac model
Hello, John,
I use this to get the model number:
+ (NSString *)computerModel
{
char modelBuffer[256];
size_t sz = sizeof(modelBuffer);
if (0 == sysctlbyname("hw.model", modelBuffer, &sz, NULL, 0)) {
modelBuffer[sizeof(modelBuffer) - 1] = 0;
return [NSString stringWithCString:modelBuffer
encoding:[NSString defaultCStringEncoding]];
}
return nil;
}
Regards, Rob.

Sorting an NSTableView bound to an NSArrayController.
Hello,
I'm writing an application that handles results for a running club.
I have an NSTableView that has columns bound to a CoreData Entity such as
Entries.arrangedObjects.position, position is an NSString that contains numbers
such as @"1" and @"2" or @"" but the position can also be @"DNF" (Did not
finish).
I have a method in the WindowController that sorts the 'Entry' objects and
handles these cases correctly returning an NSArray using:
[array sortUsingComparator:^(id obj1, id obj2)
{
NSComparisonResult r;
r =
return (r);
}];
How can I get my table view to work so that when the user clicks in the Pos.
column I can do my custom sort? at present it is doing an ASCII sort so I get
1, 10, 100, then 2, 20, 200 etc...
I now I need to put a key and sort descriptor in IB but don't know what code I
have to add to the Entity ot WindowController to handle it.
Thanks, regards, Rob.

Thanks to Ken, Dennis and Quincey.
I had an instance variable IBOutlet NSWindow *window in the header file that
was shadowing the property.
Everything is working now.
Thanks everyone for taking the time to help.

Window is created from a XIB using:
- (id)initWithManagedObjectContext:(NSManagedObjectContext *)inMoc
{
if ((self = [super initWithWindowNibName:@"RunnersWindow" owner:self]))
[self setManagedObjectContext:inMoc];
return (self);
}
- (void)windowDidLoad
{
[window setAutorecalculatesKeyViewLoop:NO];
NSLog (@"windowDidLoad: Window = %@\n", window);
}

In the XIB Files Owner is set to my WindowController sub-class.
The Files Owner's window outlet says it's linked to window but I have in the
past had problem in a different project where I had two awakeFromNibs called, I
don't know how that happened but it seems that something I did in that project
caused two instances of my window controller to be created.
How would I know if I've instantiated the window controller in my NIB? would I
see two windowDidLoad messages?

I use the window outlet in windowDidLoad and in the method called by the
NSControlTextDidEndEditingNotification notifications.

Okay, here I can see I screwed that up. I had no initialFirstResponder, now
I've set it the tab order works perfectly.
I'd still like to fix my window == NULL problem as I would like to make the
enter key move to the next field and skip fields if some earlier information
means that future fields are not required.

NSTextField Tab Order.
Hello, All,
I have a window with a number of NSTextFields in two columns. The natural flow
of information would be to fill in one column then the other but the tab order
goes left to right then down.
I've tried hooking up the nextKeyView in IB but that doesn't help. I've also
used [window setAutorecalculatesKeyViewLoop:NO]; in windowDidLoad (and in IB
it's un-ticked) which doesn't help either - mind you despite window being
hooked up in IB window == NULL but the notifications below are being called and
they don't work either.
Now I'm trying a notification system
For each NSTextField I use this in windowDidLoad:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector
(controlTextDidEndEditing:)
name:NSControlTextDidEndEditingNotification
object:titleField];
Then:
- (void)controlTextDidEndEditing:(NSNotification *)notification
{
NSTextField *f = [notification object];
if (f == titleField)
{
[titleField resignFirstResponder];
[window setInitialFirstResponder:forenameField];
}
else if (f == forenameField)
[forenameField resignFirstResponder];
[window setInitialFirstResponder:surnameField];
...
but this isn't working either.
I'm sure there must be an easier way to do this, would anyone know what it is?
Regards, Rob.

Core Image Capture: ICScanner and brightness/contrast adjustments.
Hello, I'm struggling to find documentation on using ICScanner apart from the Scanner Browser example which was really great and helped a lot but the images that are scanned are too light. In some scanner apps the user can set the brightness/contrast then scan to get a better image. Do I need to pass some values to the ICScanner to do this? Again can't find any documentation on this or anything useful from the ICScanner.h, ICDevice.h or ICScannerFunctionalUnit.h headers. I need to support 10.6 so I don't want to dump all of the code and use another framework unless I really have to.
