Re: Class Message
Hi Kevin, since you said you don't need instance variables, why not do it with a category of AppDelegate or even NSApplication (not sure about this one, just throwing it in)?

-[NSDateFormatter dateFormatFromTemplate:options:locale:] does not work as expected
Hi, I am having problems using -[NSDateFormatter dateFormatFromTemplate:options:locale:] (new in 10.6.). It’s a great API which makes world-savvy custom date formats possible. Unfortunately it does not seem to work. Examples of wrong results are: - Hour format templates like h a (12 Hour with AM/PM) are converted to format H (24 Hour) under US locale. Other combinations (ha , h, H under US or German locale) also always return H. - The template EEyMd is converted to format EE, -M-d under German locale. This is completely wrong, expected would be EE, d.M.. I filed a bug under rdar://7803429. Does anybody have similar experiences with this method? Any work around to make it work? - Kai - Test code: The following code: NSLocale* usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@en-US]; NSLocale* germanLocale = [[NSLocale alloc] initWithLocaleIdentifier:@de-DE]; NSString* format = [NSDateFormatter dateFormatFromTemplate:@h a options:0 locale:usLocale]; NSLog (@Template “h a” with US local results in �...@”, format); format = [NSDateFormatter dateFormatFromTemplate:@H options:0 locale:usLocale]; NSLog (@Template “H” with US local results in �...@”, format); format = [NSDateFormatter dateFormatFromTemplate:@h options:0 locale:usLocale]; NSLog (@Template “h” with US local results in �...@”, format); format = [NSDateFormatter dateFormatFromTemplate:@h a options:0 locale:germanLocale]; NSLog (@Template “h a” with German local results in �...@”, format); format = [NSDateFormatter dateFormatFromTemplate:@H options:0 locale:germanLocale]; NSLog (@Template “H” with German local results in �...@”, format); format = [NSDateFormatter dateFormatFromTemplate:@EEyMd options:0 locale:germanLocale]; NSLog (@Template “EEyMd” with German local results in �...@”, format); gives me this output: Template “h a” with US local results in “H” Template “H” with US local results in “H” Template “h” with US local results in “H” Template “h a” with German local results in “H” Template “H” with German local results in “H” Template “EEyMd” with German local results in “EE, -M-d” ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Trash the Preferences .plist and you get a nice fresh firstrun. I currently have ad-hock code in the AppDelegate, duplicated functionality in quiet a few apps and want to standardise on one way, cutting down on the code I need to maintain Think about it this way: a class method is a lot like a global function, except that it lives in a class-specific name space. (This gives it a slight advantage over a real global function, which pollutes the global namespace.) So, you can create a global function method like this: + (BOOL) validateFirstRun: (NSError**) outError; (If there are no parameters in the method signature other than the returned error, it's not usual to put Error in the method name.) You don't need to advertise outside of the class how this method is implemented -- no outside clients care whether there's any class instance involved. Your app delegate simply invokes [FirstRun validateFirstRun: error] and deals with the return error if any. Within the class, you can take two approaches: 1. Do everything you need with class methods, using file-local static variables for storage. You don't ever need to create an instance of the class. This works pretty well in most cases. 2. Sometimes, not having instance variables turns out to be awkward. In that case, you can have your public class method create an instance of the class, and put all the work in instance methods. Or you can use #2 if you just prefer to code with instance methods -- there's no real downside. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Attributes set in NSTextStorage ignored/overridden
I am attempting to display information in an NSTextView. The
information is added line-by-line with some lines to be displayed in
bold font and underlined, while other lines are to be displayed
normally. I add each line as follows:
tstor = [textView textStorage];
[tstor beginEditing];
[tstor appendAttributedString:[[NSAtttributedString alloc]
initWithString: --- (NSString) ---
attributes:stext]]; /* or btext for the bold,underlined text */
[tstor endEditing];
After adding the first line which should be in bold/underline,
NSLog(@tstor = %@,tstor) shows the following:
tstor = NWISSysInit:1
{
BitstreamVeraSansMono-Bold 9.00 pt. P [] (0x001922e0)
fobj=0x0018a180, spc=5.42 = NSFont;
1 = NSUnderline;
NSFont = Helvetica 12.00 pt. P [] (0x00192300) fobj=0x00150430,
spc=3.33;
}
So, all my text comes out in Helvetica 12, no underline.
I have textview as editable, and as richText
Why is the underline ignored, and why is the font overridden? I don't
understand the contradiction and the reversed syntax between the first
and third line of the log of the text storage attributes.
I have two fonts:
sfont = [NSFont fontWithName:@Bitstream Vera Sans Mono size:9.0];
bfont = [NSFont fontWithName:@Bitstream Vera Sans Mono Bold size:9.0];
NSLog of the two fonts:
sfont = BitstreamVeraSansMono-Roman 9.00 pt. P [] (0x0018a470)
fobj=0x00189e20, spc=5.42
bfont = BitstreamVeraSansMono-Bold 9.00 pt. P [] (0x0018a470)
fobj=0x0018a180, spc=5.42
two attribute dictionaries:
stext = [[NSDictionary alloc]initWithObjectsAndKeys:
NSFontAttributeName,sfont,
NSUnderlineStyleAttributeName,[NSNumber
numberWithInt:NSUnderlineStyleNone],
nil];
btext = [[NSDictionary alloc]initWithObjectsAndKeys:
NSFontAttributeName,bfont,
NSUnderlineStyleAttributeName,[NSNumber
numberWithInt:NSUnderlineStyleSingle],
nil];
NSLog of the two dictionaries:
stext = {
BitstreamVeraSansMono-Roman 9.00 pt. P [] (0x0018a470)
fobj=0x00189e20, spc=5.42 = NSFont;
0 = NSUnderline;
}
btext = {
BitstreamVeraSansMono-Bold 9.00 pt. P [] (0x0018a470)
fobj=0x0018a180, spc=5.42 = NSFont;
1 = NSUnderline;

Custom NSTextView for text annotations
Hi, I am currently working on a document reader and annotation program. This program will allow the user to import text files and annotate them, both in the margins and by attaching annotations to specific words. As the cursor is hovered over a word, its annotation will appear in some sort of coloured 'bubble' beside it. I will have a custom file format to store the locations of these annotations in relation to the text file. I am fairly new to Cocoa and I am not sure about how to implement my annotations. I do not want to use PDF because most of the imported documents will only be in text format, for example works from Project Gutenberg. I have done some searching and the closest I have come to a solution is NSTextAttachment, but this inserts an object into the flow of the text and changes the line height of the text for example. I am thinking that I will have to somehow subclass NSTextView and do some custom drawing. Is this the right way to go about it? How should I write this feature? Any advice is much appreciated.

NSTextView’s adjustScroll method
I'm trying to implement typewriter scrolling in my Cocoa text editor, keeping the insertion point centered vertically in its scrollview. Toward this end, I have subclassed NSClipView to provide a scrollToPointWithoutConstraint method, which scrolls the document to a specified point without calling constrainScrollPoint. This is necessary because for short documents the insertion point can't be centered unless we scroll beyond the document's bounds. This seems reasonably straightforward so far and does what I want. The problem comes in when I try to scroll using the scroll bars. If I'm scrolled to the end of the document, such that part of the scroll view contains an area outside the document's bounds, trying to scroll up by a small increment causes the scroll view to jump, immediately clamping to the document's actual bounds. I gather that I might need to subclass NSTextView and override the adjustScroll method; this is where my actual question begins. The proposedVisibleRect that is passed to adjustScroll already has its dimensions adjusted so that they lie within the document's actual bounds. Is there a way that I can change the value of proposedVisibleRect before adjustScroll is called? Alternatively, am I going about this entirely wrong? Any suggestions would be greatly appreciated at this point. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

After this is an explanation why custom properties are not removed, in some cases the situation becomes really bad. I found one machine with an addressbook containing nearly 100 custom properties due to lots of apps with AB integration tested on this account. After custom properties NOT being synced (as documented) I would expect doing a full reset from .Mac would solve it, but of course it does not. Anybody with an idea what went wrong here?

Hm- you haven't made it clear why you need the stack frame. The stack frame
is still there (or constructed on-the-fly), but it is an opaque, hidden

later use.

I don't see anything special about your situation. You've got the target
(self), selector (_cmd), and arguments in there. You should be able to create
an invocation with available methods, for example +[NSInvocation
invocationWithMethodSignature:], then add arguments.

So you're trying to implement continuations?
Well, I don't know continuations. I would more likely call them forwarders.
Could you perhaps
rearchitect your code to use blocks instead?
I thought about blocks, but then I need to rewrite such a block for every
method, where I want to use this functionality. Everytime adapting the method
name and the arguments in that block. That is dynamic redundancy.

I don't see anything special about your situation.
That's exactly the point. Apple uses this everytime -forward:: is called. Why
hide it now from us. It was available for years.
You've got the target (self), selector (_cmd), and arguments in there. You
should be able to create an invocation with available methods,
I never said, it's not possible. But it's a huge task to re-implement a general
method like this. If you understand, that you have to treat every different
argument type dynamically.
No touching stack frames needed! We're high-level folks here.
Not when we have to re-implement the same thing a few thousend times instead of
just once! This is called redundancy, which you as a high level guy should know
to avoid. That's the reason, why Apple implemented a general method in
-forward::.

Hi
This is a problem that occurred a few months back in a project. I Never

There is a window with three NSTextFields and a button. The button is
connected to the doPaste action and the fields are outlets
Here is the code
-(IBAction)doPaste:(id)sender{

CGEventPost(kCGHIDEventTap, eventDown);
CGEventPost(kCGHIDEventTap, eventUp);
CFRelease(eventDown);
CFRelease(eventUp);
CFRelease(sourceRef);
}
I expected that each of the fields would have their respective text pasted
into them. What actually happens is that the last field gets three copies of
it's text, Field 3, pasted into it. The other two fields are blank.
Can anybody explain why that should happen.

Removing Object form ArrayController without managedObjectContext
Hello all.
before this email I had a problem with a to-many relationship, that after
saving the other view wasn't showing the invoice details, I found the error,
but I can't find the solution.
So what was happening, was that after saving I was clearing the data of the
NSArraycontroller that was used by the table that allowed insertion of
ItemXInvoice items, then after save was successful, I was doing the following:
//===
//Clears the Fields of the view
//===
-(void)clearFieldsData{
[_itemsArrayController removeObjectsAtArrangedObjectIndexes:[NSIndexSet
indexSetWithIndexesInRange:NSMakeRange(0, [[_itemsArrayController
arrangedObjects] count])]];
[_dueDateSelection release];
_newInvoice = nil;
}
so my table was clean again and ready to create a new invoice, or at least that
was what I thought, but unfortunately when I wanted to check the created
invoice in the other view, I couldn't see any detail, ItemXInvoices, but after
closing the app, I was NOT able to see them. I commented the line that called
the above method and then I was able to see the invoice details of the newly
created invoice.
My guess was that when removing the objects form the array controller, these
were being removed form the MOC, and therefore I couldn't see them in the
consultation mode, only after restarting the app when the MOC fetch again the
data.
Now I need to be able to clean the table after saving, otherwise I can't create
more items unless I restart the app, or if I clean the table I must restart the
app in order to see the newly created invoice's details.
I dunno what can I do here...
Please any advice will be appreciate it.
Thanks in advance
Gustavo

AppleScriptability Meets NSOperation
I do some lengthy, multi-step tasks in an app like this: * Wrap each of their dozen or so steps in an NSOperation. * Set dependencies so that they execute in sequence. * Add them to a suspended NSOperationQueue. * Un-suspend the queue. If an error occurs, all operations in the queue are cancelled and all ends gracefully. But many of the operations involve updating progress in the user interface, or accessing the document's managed object context, so they actually call back to performSelectorOnMainThread:, via a handy little wrapper in my NSOperation subclass. The user interface unblocks between operations, and I'm happy with the way this works. But when I invoke a task like this from AppleScript, of course, it returns immediately after loading the queue. That's no good, especially if an error occurs -- the script has already moved on. All I can think of is to implement a whole-nother script mode execution mechanism for these tasks, that maybe instead of wrapping the steps as NSOperations would branch to wrap them as NSInvocations, then collect them in an array, and finally loop to invoke each. The user interface would be blocked from beginning to end, but scripters should expect that by definition. However I have this dent in my forehead which has developed from testing similar inventions. Is there a neater way to do this? Jerry Krinock ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

CALayer Grid jerky animation
Hi All, I have a grid of equal sized CALayers in a parent layer - in my case it's a calendar grid - but it could also be a chess board for example. After adding all the cell (child) layers to the parent layer I iterate through them again to add constraints. The parent layer can have it's width resized. The height is constant. For all cell layers I added the following constraint: [cellLayer addConstraint:[CAConstraintconstraintWithAttribute:kCAConstraintWidth relativeTo:@superlayer attribute:kCAConstraintWidth scale:(1/numColumns) offset:0]]; so that as the parent layer is resized all the child layers are resized as well. For all layers except those in the right most column I add the following constraint: [cellLayer addConstraint:[CAConstraint constraintWithAttribute:kCAConstraintMaxX relativeTo:[rightLayer name] attribute:kCAConstraintMinX offset:0]]; so that each layer's right edge is always touching the left edge of the layer to it's right. Finally - the layers in the right most column are constrained by: [cellLayer addConstraint:[CAConstraint constraintWithAttribute:kCAConstraintMaxX relativeTo:@superlayer attribute:kCAConstraintMaxX offset:0]]; so that their right edge always matches the right edge of the parent layer. My problem is that when the parent layer is resized the animation of the layers being resized/moved is jerky. The child layers are moved/resized after the parent layer is finished resizing. Is there a way to make this smoother? I would love to copy how iCal does it - where the rectangles (which I assume are CALayers) containing the appointments are smoothly resized as the iCal window is being resized. Thanks!

The Core Data managed object context is the data model, the M part of MVC design, and the array controllers are merely glue objects that simplify the V. Array controllers aren't really containers, they're proxy objects for containers in the data model, sort of.

An array controller won't remove MO's unless you have told it to. Check the

In IB Im not setting the Delete Objects on Remove because the only binding it

remove them form the MOC,

This is a sign of poor design. The items array controller should use the
invoice relationship as its content and it will take care of itself.
I have, Invoice - ItemXInvoice Invoice, the Array controller I set up
with ItemXInvoice entity, and when I click an add button I do:
Item * newItem = [NSEntityDescription
insertNewObjectForEntityForName:@Item inManagedObjectContext:[self
managedObjectContext]];
ItemXInvoice * newItemXInvoice = [NSEntityDescription
insertNewObjectForEntityForName:@ItemXInvoice inManagedObjectContext: [self
managedObjectContext]];
[newItemXInvoice setValue:newItem forKey:@toItem];
[newItem addToInvoiceXItemsObject:newItemXInvoice];
[_itemsArrayController addObject:newItemXInvoice];
if(_newInvoice == nil){
_newInvoice = [NSEntityDescription
insertNewObjectForEntityForName:@Invoice inManagedObjectContext:[self
managedObjectContext]];
}
[_newInvoice addToItemsXInvoiceObject:newItemXInvoice];
So Im creating a ItemXInvoice relate it to an Item and then relate it to the
Invoice relationship as you say. Unless I misunderstood your point and the
NSArrayController (ItemXInvoice) the Array Content binding shall be set to the
instance with keypath: _newInvoice.toItemXInvoice... I dunno its late here in

This also avoids the need for the user to mess around with 'timeout' blocks and won't freeze your GUI while the script is waiting for a response. (I think the SIG recommends this approach in these situations.) A third option would be to go the notification route, where you require client scripts to be run as stay-open applets; when the task completes, your application sends a command to the applet to let it know.

for the key toItem has changed without an appropriate KVO notification
being sent. Check the KVO-compliance of the ItemXInvoice class.
Somewhere you've changed the toItem property without going through the setter
method properly.
I then checked the class and in the setItem Im doing:

[value retain];
[self setPrimitiveValue:value forKey:@toItem];
[self didChangeValueForKey:@toItem];
}
Where'd you get this ? It's not from any of the Xcode templates, and it's
wrong (leaks). There is no need to retain value, and since this setter doesn't
do anything interesting, you should just delete it and use the @dynamic

//Set the creationItemPrice for each ItemXInvoice
}
uhm. lots of not healthy things here. You shouldn't be calling
-willChange/-didChange explicitly here. That's the purpose of the setter
methods (or KVC). Not sure why a bunch of this code isn't in -awakeFromInsert.
Or why you have _tempItemsArray at all.
As others have noted, Cocoa Bindings isn't your Model layer and trying to use
it that way is both tedious and error prone. It's the Controller layer that
intermediates between your Model objects and the UI. You really want to focus
these kinds object graph (data management) operations on the Core Data objects,
and leverage those APIs along with KVO and NSNotification.

Re: Sending a Cmd-V keystroke
Hi Thanks to all who have replied to this. I will try to explain to you why I was looking at this and what I have discovered. In the education establishment where I was employed, one of the departments had an AppleScript that was used to parse the standard format emails received from students and to process the data. The department wanted to have a program to do the same and to store the data in an SQLite format to be used as an archive and to be viewed via other applications. I agreed to do this as the requirement could be met using a very simple core data program. As the AppleScript performed the parsing I decide to use it in the program and called the handlers within to get the data into the program. While I was writing the program the head of the department, who had written the original AppleScript, asked if it would not be simpler just to paste the data from the script into the fields in the program. I told him it was not really simpler as we could easily propagate the fields within the program which was the correct way to do it but when I had finished I would show him how it could be done by pasting. Of course it did not work. I fiddled about with it for a while and then dumped it. Recently I had a slack period and decided to look again to see what was happening just as a matter of interest. I had decided it was probably a problem with the queue or dequeueing but could not see what. A few days ago, after corresponding with Jim Correia who also stated het thought it was a dequeueing problem, I wrote a method that emulated the tab key being pressed to use in place of makeFirstResponder. So I had a method emulating the CMD-v (pasteIt) and one for the tab key (tabIt). The sequence of calls was put the first text on the pasteboard pasteIt tabIt put the second text on the pasteboard pasteIt tabIt put the third text on the pasteboard pasteIt With this set up all three fields get text pasted into them but all of them have the third piece of text that was pasted onto the pasteboard. It looks like the system puts all three pieces of text on the pasteboard before the first call to paste gets dequeued in the app. I have satisfied myself about what is happening so have now moved on to pastures new.

CIFilter and grayscale image
Hi, I would like to apply a custom CIFilter to a grayscale image. The problem is that the kernel of the CIFilter is for RGB images. So the output is a RGB image but I would like to convert it in grayscale and I have no idea how I could do that.This would be to display in a IKImageview. If someone have an idea let me know,Thanks,Paul _ Hotmail: Free, trusted and rich email service. https://signup.live.com/signup.aspx?id=60969___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: AppleScriptability Meets NSOperation

The Apple Event Manager supports suspend and resume
Great tip, has. I searched and found
Cocoa Scripting Guide
How Cocoa Applications Handle Apple Events
Suspending and Resuming Apple Events and Script Commands
In there, it looks like -suspendExecution and -resumeExecutionWithResult: have
been provided for my situation exactly. (I am using Cocoa Scripting and
NSScriptCommand.)
And it appears that we have solved the problem. But since I couldn't find any
sample code using -suspendExecution or -resumeExecutionWithResult:, I shall
describe this so I can find it in the list archives next time I forget :)
In my subclass' implementation of performDefaultImplementation:,
[[SSYOperationQueue mainQueue] setScriptCommand:self] ;
[self suspendExecution] ;
In the first line, I stash the command away in an ivar for later, which is
necessary because -suspendExecution causes -currentCommand to subsequently
return nil.
Then in my asynchronous completion routine,
NSScriptCommand* scriptCommand = [[SSYOperationQueue maenQueue]
scriptCommand] ;
if (!ok) {
[scriptCommand setScriptErrorNumber:errorValue] ;
[scriptCommand setScriptErrorString:errorString] ;
}
[scriptCommand resumeExecutionWithResult:nil] ;
Seems to work perfectly, although it's kind of spooky how it works. Maybe
they're setting up a sleeping thread for me behind the scenes.
And thank you very much has!! You really kept me from making a big mistake
today.

Re: Removing Object form ArrayController without managedObjectContext

I have, Invoice - ItemXInvoice Invoice, the Array controller I set

Whenever possible, manipulate relationships directly. Perhaps you do this, but
the code isn't shown. If your array controller is bound to the relationship,
you shouldn't have make any calls to it at all. It will update itself. If it
isn't updating, it means you aren't using your relationships properly.
Item * newItem = [NSEntityDescription
insertNewObjectForEntityForName:@Item inManagedObjectContext:[self
managedObjectContext]];
ItemXInvoice * newItemXInvoice = [NSEntityDescription
insertNewObjectForEntityForName:@ItemXInvoice inManagedObjectContext: [self
managedObjectContext]];
[newItemXInvoice setValue:newItem forKey:@toItem];
[newItem addToInvoiceXItemsObject:newItemXInvoice];
[_itemsArrayController addObject:newItemXInvoice];
if(_newInvoice == nil){
_newInvoice = [NSEntityDescription
insertNewObjectForEntityForName:@Invoice inManagedObjectContext:[self
managedObjectContext]];
}
[_newInvoice addToItemsXInvoiceObject:newItemXInvoice];
So Im creating a ItemXInvoice relate it to an Item and then relate it to the
Invoice relationship as you say. Unless I misunderstood your point and the
NSArrayController (ItemXInvoice) the Array Content binding shall be set to
the instance with keypath: _newInvoice.toItemXInvoice... I dunno its late
here in this part of the work, Im just rumble around..
Any thoughts?
I would need to know what the -add* methods do to make any suggestions. Chances
are, these methods are not updating the relationships properly.

If someone have an idea let me know,Thanks,Paul A greyscale RGB image contains identical data in the three channels, so throw any two away. You can probably do that easily by creating a bitmap having the greyscale characteristics you want and drawing the RGB image into it. That's likely to be faster than picking over the bitmap data yourself. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to get wifi information
If you're just playing around with an app that only you will be using, have fun exploring. However, if you're planning to release it through Apple's store, I've read that they will reject your app if it's using private API calls.
