Sigh - I had hoped that this Carbon-message would indicate the source of the 
problem - obviously I was wrong.

The backtrace for the first exception '[<_NSFaultingMutableSet 0x10048a950>

when setting the predicate 'aValue BEGINSWITH[n] "a" AND ANY theBs.bValue ==

Interfacing cocoa/obj-c within a C plug-in API

[Rich E]

Hi,

I am new to Cocoa and Objective-C both, but I need the two in order to get
tablet functionality into one of my favorite applications (Puredata) on Mac
OS X. First off, I know that you can get tablet event data through the
Carbon API, but I have ran into enough problems (along with no 64-bit
support) that I think trying it with Cocoa is worth a shot.  Puredata has an
API for writing plug-in's in C and I hear that it is possible to write the
entire plug-in in Obj-C but leave the host callback functions in standard C,
yet I still don't understand how to embark.

I learn best by examples, does anyone know of any existing C applications
that make use of Cocoa or Objective-C?  Else, any advice on how to combine
these two with a host written in C?

Thanks for any help or advice,
Rich

Cocoa sits atop Carbon. So all this means is that an exception didn't get 
caught until it reached the Carbon layers. I don't think such exceptions were 
previously logged before 10.6, though they undoubtedly did occur.

You need to concentrate on where the exception came from and stop it from being 
raised, not where it ended up getting caught.

I believe I've seen this message when I try to observe the "many" end of a 
to-many relation using KVO.  That's against the law.  (And I do remember 
reading that one in the documentation, mmalc!)  Probably it was in the KVO 
Programming guide??

Bindings uses KVO.  Clue: Look at any bindings hanging on that array controller.

Do not worry about these words.  It is definitely an error you need to deal 
with.  Don't worry about where it came from -- it came from "the bowels of the 
Mac OS".  "HI" probably means "Human Interface" but knowing that doesn't help 
you at all.

NSTabView Bindings

[Gerriet M. Denkmann]

I am trying to bind "editable" of an NSTableColumn to ObjectController 
tabView.selectedIndex
(The tab view has two items: Read and Edit. When the first item is selected, my 
table column should not be editable).

But I am told:
[ valueForUndefinedKey:]: this class is not key value 
coding-compliant for the key selectedIndex.

On the other hand, the Cocoa Bindings Reference for NSTabView says: 
"selectedIndex
An integer value that specifies the index of the selected item in the 
NSTabView. When the selection changes in the NSTabView, this value is updated 
with the index of the newly selected item."

So: what is going on? 
And: how do I make my table column editable if and only if the first tab view 
item is selected?

Kind regards,

Gerriet.

One approach to avoid the whole IBOutlet excess would be to create  
subclasses of the standard view classes which, when they are loaded,  
use their contents/title as the key and pass it to NSLocalizedString 
(). That way, your NIBs only contain keys, and the .strings files  
can hold the actual strings, including comments.


Another possibility: instead of creating a bunch of subclasses and  
having to specify that subclass for each view you create in IB, you  
could write a method that recurses through all views in a window.   
Check each view for a "title" or "name" property (maybe "stringValue"  
too), and maybe use some convention like #TITLE# to indicate you want  
to replace that title or name with a localized string to be gotten via  
NSLocalizedString().  Check whether the view is a table view that  
displays column headers, and if so, iterate through its columns.  Do  
similar special-casing for tab views and segmented views and anything  
else that needs it.


This method could be in its own utility class, where it could be  
called by awakeFromNib.  Offhand I think this is how I would do it if  
I wanted to take the approach of putting keys in the nib.

It's best not to localize in a locale unless you are going to do it  
correctly!
That means hand tooling the UI. Apple realized long ago that GUI  
elements must be localized correctly. This means far more than  
translation with the inevitable string length differences. This means  
making an interface make sense in a localized format. One size fits  
all only when the UI is intuitive and self explanatory. (Photobooth is  
an excellent example)


It tends to be true that your UI could use improvement if it is overly  
textual. A good UI design can avoid localization being painful. This  
is the true shortcut in localization

Are you aware that the  context you get from   UIGraphicsBeginImageContext  has 
its origin
at upper left ?

In any case, I have posted a mini example that *appears* to do what you want, 
but based
on the descriptions, I might have misunderstood, in which case please excuse me 
for
wasting bandwidth . . .

Core Data _NSFaultingMutableSet Exception

[Gerriet M. Denkmann]

Core Data model with two entities: A and B.

A has property aValue and a relation theBs to one or more Bs.

B has a property bValue.

Two NSTableViews (tabelView1 and tableView2 ) with each controlled by an 
NSArrayController (arrayController1 and arrayController2).

Everything works fine when I send:
 [ arrayController1 setFilterPredicate: "aValue BEGINSWITH[n] "a""];
 [ arrayController2 setFilterPredicate: "aValue containsInside: "a""];
(Well, I do send real predicates, but they contain the strings shown above. 
"containsInside:" is declared in a category on NSString)

But when I use:
 [ arrayController1 setFilterPredicate: "aValue BEGINSWITH[n] "a" AND ANY 
theBs.bValue == "xx""];
I get an exeption:

 HIToolbox: ignoring exception '[<_NSFaultingMutableSet 0x1001f5d00> 
addObserver:forKeyPath:options:context:] is not supported. Key path: bValue' 
that raised inside Carbon event dispatch

When later I reset the filterPredicates back to the simple (working) mode, I 
get another exception:
 HIToolbox: ignoring exception 'Cannot remove an observer  
for the key path "theBs.bValue" from  because it is not 
registered as an observer.' that raised inside Carbon event dispatch

1. This is a Cocoa document based app, using Core Data. Why this "Carbon event 
dispatch". And who is HIToolbox?

2. I have an identical app, which works perfectly.
(Obviously these two apps are NOT identical, but I really cannot find any 
differences. I tried to remove all changes I made to the newer app, but the 
exception remains).

I spend now more than a day chasing this exception. Any hints would be most 
welcome. 10.6.2.


Kind regards,

Gerriet.

Plus 1. I've done something similar in the past. My approach was to
see if "Untitled" was already taken, if so try "Untitled 2", etc. From
memory I kept going until 20 (a number all but the most perverse user
wouldn't reach in my case). If "Untitled 20" (& everything preceding)
was taken it got named with a date stamp, "Untitled 2009122215353803"
for example.

Re: UIImage and shadows, WAS: Re: Please if some one knows

[Development]

Then I don't understand how to do this.

Do I create the context at this larger size? because that's what I did.
Do I drawInRect the image at it's original size? Because that's what I did. 

As near as I can tell, no matter what I do, the image itself, not accounting 
for the shadow, is drawn in the upper left corner. this causes a negative 
shadow, or one to the upper left, to be cut off by the edge of the context. 
I have attempted using drawAtPoint, and accounting for the negative shadow by 
moving the point an amount that should accommodate the shadow. It did not work.

Now if the shadow is to the lower right, the adjustments I make work perfectly 
every time and the shadow is exactly what it should be. 

I think the point is that I do not understand the context drawing. I thought I 
did but it should be painfully obvious from this thread that I do not.

Try thinking instead of flailing about throwing code at it.

You need a bigger image to accommodate the shadow. But the image you want to 
composite on top is the same size as it always was. So you need to keep its 
original size around so you can draw it at that size but into the larger image 
context. If you draw it at the new size you are back at square one, but larger.

Thanks for all your help and suggestions.

What I ended up was: subclassing NSArrayController and overriding "newObject" 
to return a new object prefilled with some some nice values, including setting 
my uniqueKey to "undefined", "undefined_1", "undefined_2", etc.
This will break of course if the user (out of sheer perversity) has already 
created an "undefined_4".

But as "real" entries never will look like "undefined_..." there is no problem 
with eliminating duplicating entities later.

And, as I said, editiing "undefined_..." into some "real" value will (via: 
Validates immediately) catch real duplicates.

Kind reagards,

Gerriet.

I know that this will be unsatisfying, but the real reason that iPhone
apps can't use GC is because Apple has not yet made GC available for
the iPhone.

Anything further would be pure speculation, because Apple doesn't talk
about things like that.

CGRect newSelf = CGRectMake(self.frame.origin.x, self.frame.origin.y,

self.frame = newSelf;

Re: UIImage and shadows, WAS: Re: Please if some one knows

[Development]

Ok
I was wondering if that was what I was doing wrong. I've tried messing with the 
size of the context but it gives me trouble. Do I need to adjust the size of 
the UIImageView also? or since clipping is off is it ok in it's original size?
Also will the drawing to the offscreen context take place at it's center or do 
I need to set a center and specifically tell the image to draw there? Finally 
when I call [rotatingView.image drawInRect:rotatingView.bounds 
blendMode:kCGBlendModeNormal alpha:1.0]; is the rotatingView.bounds the correct 
rect to draw in to?

Your drawing to an offscreen context, and in doing so your asking to create a 
context that is a certain size. If you draw outside of that area, then your 
going to lose that drawing, period, because there is no place to put it.

If you want to add a shadow, your going to have to calculate how much extra 
space you need and increase the context you draw by that size. A reasonable 
approximation is the shadow offset plus the shadow spread. Either way, your not 
going to be able to use the image's original size as the final size because you 
are explicitly asking to draw outside of that original image.

But something else should happen, which is that, if the filename is, for

Note the tilde.

I've never seen this documented anywhere, though.  Also, I've never tried to 
open such a migrated document with an earlier app version, but it would make 
sense that the earlier version would look for and automatically load the old 
tilde document if it couldn't load the current document due to model changed.

I recently had alot of trouble with Core Data migration, and saw alot of crap, 
but never saw a migration occur without the tilde doc appearing.  If you figure 
out how you broke it, let us know.  I'm worried that I might need to know 
someday ;)

Cocoa windows have the peculiar behavior that key down events without the 
command, control, or function key mask get sent to the window first, and then 
the menu.  Events with any of those flags set get sent to the main menu first.  
Pressing an arrow key generates an event with the function key mask set, but 
the spacebar does not set any of these mask bits, which explains the behavior 
you're seeing.  Carbon windows (including NSCarbonWindow) send all events to 
the main menu first, which is why the behavior is different between Cocoa and 
Carbon windows.

I think your suggestion of dynamically adding or removing the key equivalent is 
sound.  The best place to do this would be in either an implementation of 
menuNeedsUpdate: in the menu's delegate, or in validateMenuItem: in the target 
of the menu item.

To get Carbon's notion of the focus, you can do this:

HIViewRef focusedView = NULL;
HIViewGetFocus(GetUserFocusWindow(), &focusedView, NULL);

To get Cocoa's notion, you would write:

NSResponder *fr = [[NSApp keyWindow] firstResponder]

The question of "who really has the focus" is a little complicated, because it 
depends on who is dispatching events.  If you have a Carbon window in a Cocoa 
app, HIViewGetFocus() will normally give you a NULL view if a Cocoa window is 
focused, so you might start by checking with Carbon, and then checking with 
Cocoa if the Carbon focus is not a text field.

Hope this helps,
-Peter

UIImage and shadows, WAS: Re: Please if some one knows

[Development]

Ok ok, sorry for double posting. Honestly I'm thinking I'm trying to do 
something that simply isn't possible though. 

I'll try my question again. Ok, I have a UIImageView. I am trying to draw a 
shadow under the UIImage it holds. Now if I make the UIImageView's bounds some 
ungodly size, like the size of the screen it draws shadows perfectly but 
obviously this is not acceptable. So I don't understand what I am doing wrong. 
I've tried turning off the clipstobounds but that doesn't help unless the 
context I am drawing is is clipping in which case I do not know how to turn it 
off. But at least in the UIImageView it is not clipping. 

So the first question: How do I turn of clipping in the context I'm drawing too?

Second, is the problem something else in my code? Like I said before I get a 
perfect shadow unfortunately it is clipped to the edges of the view so it's 
useless. 
I have tried to enlarge the view by the amount of the offset but this does 
nothing except make the view bigger. The image still draws in the same upper 
right location rather than the center as I thought I had set it to with the 
content mode.  I've also tried using the CG draw image method but it draws 
upside down and since I don't want to go through flipping the image every time 
I add a shadow I gave up on that. It didn't give me any better results though 
otherwise I'd have used it. Do I need to do some kind of Affinetransform to 
translate the context? 

Lastly if I am wasting my time with this please let me know. I've spent hours 
now on Google and cannot find any examples of adding a shadow to a UIImage, at 
least not this way.

-(void)addShadow:(CGSize)myShadowOffset darkness:(CGFloat)darkness 
spread:(CGFloat)spread
{

UIGraphicsBeginImageContext(rotatingView.bounds.size);
CGContextRef myContext =  UIGraphicsGetCurrentContext();

float   myColorValues[] = {0, 0, 0, darkness};
CGColorRef  myColor;
CGColorSpaceRef myColorSpace;


myColorSpace = CGColorSpaceCreateDeviceRGB ();
myColor = CGColorCreate (myColorSpace, myColorValues);


CGContextSetShadowWithColor (myContext, myShadowOffset, spread, 
myColor);

[rotatingView.image drawInRect:rotatingView.bounds
 blendMode:kCGBlendModeNormal 
alpha:1.0];


CGColorRelease (myColor);
CGColorSpaceRelease (myColorSpace);

UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
rotatingView.image  = imageCopy;

 One approach to avoid the whole IBOutlet excess would be to create subclasses 
of the standard view classes which, when they are loaded, use their 
contents/title as the key and pass it to NSLocalizedString(). That way, your 
NIBs only contain keys, and the .strings files can hold the actual strings, 
including comments.

Well, of course there are tools for this.  I use and recommend Max Seelemann's 
Localization Suite, and just learned that it has now been open-sourced.  This 
is great news, since a localization tool is something that you'll often want to 
tweak.  For example, I'd love to make it scriptable from the command line so I 
can add it to my Build script.

http://www.loc-suite.org/

More good news is that Max is that it looks like Max is actively working on it.

Since any app can by definition do an infinite number of tricks (and errors), 
the "test coverage" they get when they "run the app" is going to be 85% at best 
before they get tired of mousing around and ship it back to you.  So, I would 
recommend giving this localizer good comments.  I try to make my strings files 
read like API documentation, with comments defining the "contract" stating how 
each string can be used (and re-used).

> How have others tackled localization?

The dearth of replies should tell you something :)

Here's my answer:  A combination of techniques.  Localization is always costly, 
iterative, compromised, and imperfect.  Some have used each of the techniques 
you propose, and others have rejected them.  They may well be optimum for your 
situation.  Judging from your post, you are a good tech writer and thus might 
want to rely heavily on .strings comments as I do, and choose localizers which 
do the same.

Re: Localization strategies?

[François Guillet]

Just my 2c gained from translating UIs in french. Localized strings can show a 
great variation in length even among close languages such as english and 
french. Moreover, english allows for short sentence/syntax whereas french does 
not, at least not easily.

From what I've seen, there are two strategies to adapt to different strings 
lengths :
-a managed layout (not too bad but not perfect)
-designing as many UI elements as locales (perfect but tedious).

AFAIK Apple chose the second solution, so that's about the only way to go on 
this platform I suppose. Substitution of localized strings in english UI 
elements (eg dialogs) will result in either text being clipped out of labels, 
label frames too wide in english because they have to make way for other 
localized strings or localized strings too short to make sense because they 
have to fit.

And sometimes, the syntax has to change anyway and the dialog has to be 
rethought somewhat. So all in all, specifically designing UI elements for each 
locale make sense if you want the best results. It is also time consuming and 
thus (probably) expensive.

It's weird to see big companies fall into localization blunders. Pixar's 
Wall.E, for example, shows at some point in the movie the axiom ship "Operation 
Manual" which in french is translated as "Manuel d'Opération", an easy 
translation except we never refer to operation manuals using this term  
(although it's grammatically correct).

I've noticed that doing this now throws a warning when the xib is compiled that 
the autosave name should be supplied by an override of the 
-windowFrameAutosaveName method in the window controller, and not set in IB. 
Setting the string empty in IB removes the warning. I don't think I saw any

Well, perhaps the OP would like to clarify what he did mean. It seems 
unambiguous to me, but sometimes it is hard to make oneself understood when 
describing code, rather than just posting the code.

Regarding the use of different completion methods based on manipulating some 
common root name, I think that's a bit strange, misguided even. It's a lot 
simpler and self-documenting just to declare a protocol, formal or informal, 
and have the callback conform to that, passing a different target to be called 
back. That's what Cocoa itself does for sheets and elsewhere, and I follow that 
pattern as well, on the basis that Apple are leading by example. I've never 
seen the other approach taken in Apple's code, though if you have a concrete 
counterexample, I'd be interested to see it.

If someone does, they'll answer eventually, I'm sure.

It's not good etiquette t repost the same question repeatedly, especially under 
different titles - that just breaks up the thread and makes it less likely 
you'll get an answer.

Please if some one knows

[Development]

I really could use some help on this shadow issue I have been having. Does any 
one know anything about drawing shadows around images in UIImageViews?

Below is code that gives me a shadow but the shadow is clipped to the edge of 
the view, how can I get an unclipped shadow?

UIGraphicsBeginImageContext(self.frame.size);
CGContextRef myContext =  UIGraphicsGetCurrentContext();



   float   myColorValues[] = {0, 0, 0, darkness};// 3
   CGColorRef  myColor;// 4
   CGColorSpaceRef myColorSpace;
   CGContextSaveGState(myContext);// 6

   myColorSpace = CGColorSpaceCreateDeviceRGB ();// 9
   myColor = CGColorCreate (myColorSpace, myColorValues);// 10
   CGContextSetShadowWithColor (myContext, myShadowOffset, spread, myColor);// 
11
   // Your drawing code here// 12
  // CGContextDrawImage(myContext, rotatingView.frame,imgRef);


rotatingView.clipsToBounds = NO;
[rotatingView.image drawInRect:rotatingView.frame
 blendMode:kCGBlendModeNormal 
alpha:.5];
   CGColorRelease (myColor);// 13
   CGColorSpaceRelease (myColorSpace); // 14

UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();
CGContextRestoreGState(myContext);
UIGraphicsEndImageContext();

rotatingView.image = 
imageCopy;___

This is a bug in Foundation (rdar://6855192). The compiler optimizer inlined 
away the call to _NSLockError() inside Foundation, so it bypasses the 
breakpoint. Try putting a breakpoint on NSLog() instead.

Re: tracking EXC_BAD_ACCESS error in applescript command

[François Guillet]

That was a copy of the original call stack before I subclass NSScriptCommand. 
If I subclass NSScriptCommand and call executeCommand from this subclass, then 
the crash occurs as before, but of course the call stack changes accordingly. 
Anyway I put breakpoints in my subclass' methods to make sure I get through 
them.

I've found a workaround which anyway is the way I originally wanted scripting 
to work. I have the document return an object of (say) FooClass through the 
property foo. Then I declare an object-first command (say check) and implement 
the command handler in the FooClass class. Then the applescript statement :

check foo of front document

does work fine. So I can't find a way of doing "check front document" using 
NSScriptCommand's executeCommand but I can do so on an object contained by the 
document...

As others have said, you probably want awakeFromInsert.

Depending what kind of 'unique' value you want, you could create a
unique string like this:

CFUUIDRef uuid = CFUUIDCreate (kCFAllocatorDefault);
if (uuid)
{
uuidStr = NSMakeCollectable (CFUUIDCreateString 
(kCFAllocatorDefault,
uuid));
CFRelease (uuid);
}

If you want/need to compare to other objects of the same entity type,
then be warned that performing a fetch within awakeFromInsert is
probably not a good idea.  NSArrayController doesn't like it when you do that.

How well does it handle something like 1.0.1b5, or something to that effect, 
though? I knocked out a category on NSString several years ago that converts 
back and forth between a string and Apple's NumVersion structure and provides a 
comparison method. I'm willing to share, or can post it somewhere if there's a 
common site for such things.

Connect the menu item to the "First Responder" in Interface Builder.
At runtime, Cocoa's event-handling machinery will then look through
the responder chain (which includes, among other things, the
currently-active document) to find an object that has the required
action method.

For details, have a look at:

Simple question on Menus and Document-based apps

[Henri Häkkinen]

Hello.

This is probably a basic question but I haven't been able to find an answer 
from the ADC guides so far.

So I have a simple document-based application which has MyDocument with some 
other classes. The application has the default MainMenu.xib and MyDocument.xib 
interface files. I would like to add a menu item to the MainMenu, which would 
call an IBAction method on the MyDocument class. However, the document class 
and the main menu are on different xib files so I can't make the connection.

What is the Right Way to handle these kinds of things in Cocoa?

Re: Is this possible?

[Development]

Ok,
I have managed to get a beautiful shadow drawn in my rotating view (A 
view I used to rotate images so they don't distort). The rotating view sits 
inside an an image view.  so it is layered as follows: 
ImageView(parent)->rotatingView(child)->image

Anyway. I get a lovely shadow, but there is still a problem, well two actually. 
First the shadow appears to be drawn on top of the image rather than under it. 
Second, it gets clipped to the edges of the rotating image view. I have already 
set rotatingView.clipsToBounds = NO; but that does not help.

Below is the code.

UIGraphicsBeginImageContext(self.frame.size);
CGContextRef myContext =  UIGraphicsGetCurrentContext();



float   myColorValues[] = {0, 0, 0, darkness};// 3
CGColorRef  myColor;// 4
CGColorSpaceRef myColorSpace;
CGContextSaveGState(myContext);// 6

myColorSpace = CGColorSpaceCreateDeviceRGB ();// 9
myColor = CGColorCreate (myColorSpace, myColorValues);// 10
CGContextSetShadowWithColor (myContext, myShadowOffset, spread, myColor);// 
11
// Your drawing code here// 12
   // CGContextDrawImage(myContext, rotatingView.frame,imgRef);


rotatingView.clipsToBounds = NO;
[rotatingView.image drawInRect:rotatingView.frame
 blendMode:kCGBlendModeNormal 
alpha:.5];
CGColorRelease (myColor);// 13
CGColorSpaceRelease (myColorSpace); // 14

UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();
CGContextRestoreGState(myContext);
UIGraphicsEndImageContext();

How do you tell an Outline View item to enter edit mode from a pop up menu.
Just like when i double click on it?

any clues?

Yes, you can do that in IB. It's the "Autosave" in the Attributes pane

You can put that into UserDefaults.

You can't.  It's a fundamental part of the design of NSOperation.

It's not just that support for it was left out of the design.  In 
multi-threaded coding, it is sometimes very important that certain state 
changes can only go in one direction (not cancelled -> cancelled, not executing 
or finished -> executing and not finished -> not executing and finished, etc.). 
 It is very likely that NSOperationQueue would break if an NSOperation could 
change state in the other direction.

Make your NSOperations have a relationship to some other object which holds the 
state that persists.  Serially create NSOperations which each have a 
relationship to this persistent state object, one after the other.

Ken

[A] Resizing a window to show full rows from a table view

[Chuck Remes]

I searched around but could not find an answer to the problem of  
enforcing a particular window size so that only "whole" rows are shown  
in a table view. I have archives of this list going back to 2002 but  
nothing suitable popped up.


Here's the code in objective-j (Cappuccino framework).

/*
 * Enforce a window size that shows only whole rows instead
 * of the default fractional rows.
 */
- (void)windowDidResize:(CPNotification)notification
{
var window = [self window],
superFrame = [window frame],
tableSize = [scrollView contentSize],
frameDelta = superFrame.size.height - tableSize.height,
rowHeight = [theTable rowHeight],
visibleRows = FLOOR(tableSize.height / rowHeight);

tableHeight = rowHeight * visibleRows;

superFrame.size.height = tableHeight + frameDelta;

[window setFrame:superFrame];
}


Four items of note regarding this code.

1. This should be done in the windowWillResize:toSize delegate method  
instead of a direct call to setFrame but Cappuccino doesn't support  
that delegate yet.


2. The line "window = [self window]" should probably be "window =  
[notification object]" when translating to objective-c but for some  
reason that isn't working right in Cappuccino.


3. FLOOR is a macro corresponding to whatever is Math.floor in your  
host language. Adjust accordingly.


4. Computing a frame delta between the table view's visible content  
size and the window frame gives us the correct behavior even when  
there are other controls or elements inside the window. Some sample  
code I saw was tracking the size of specific fields and doing a lot  
more math just to accomplish this task.


If anyone has an improved methodology, please share.

Is there anything in Cocoa/Carbon to retrieve ACL From files?
Or do i have to mess around with the ACL Library directly ?

For compatibility reasons, there are a number of cases in which  
NSBundle objects will continue to be retained by the system even when  
you have released all of your references to them, so you may not see  
your bundles deallocated, but in any event what I would recommend is  
that if you have loaded an NSBundle and wish to continue to use the  
code from it, you should keep a reference to the NSBundle for as long  
as you continue to use it.  This is definitely the case for code  
loaded using CFBundle--if you want to continue using it, keep a  
reference to the CFBundle.

Releasing an NSBundle

[Dave DeLong]

Hi everyone,

I'm working on a simple plugin-based Foundation tool, and I have a question 
regarding NSBundles.

I have a function in my tool that discovers all classes that conform to my 
plugin protocol.  It does this by iterating through the list of loaded classes 
and testing each class to see if it conforms to my plugin protocol.  If it 
does, it adds that class to an array for later use.

This function also looks inside a plugins directory for plugins that might be 
created later to add extra functionality.  It creates an NSBundle object for 
each item in the plugins directory, and then tries to retrieve the 
principalClass from the bundle to test for protocol conformance.  If the class 
is compliant, it gets added to the list.  If it doesn't, the bundle gets 
explicitly unloaded.  However, after either case, the NSBundle object itself is 
released, because once I have the class object, I don't need the bundle object 
itself anymore.

Here's the basic idea of what I'm doing (minus obvious error checking, etc)

for (NSString * potentialPluginPath in pluginFolder) {
  NSBundle * plugin = [[NSBundle alloc] initWithPath:potentialPluginPath];
  [plugin load];
  Class principalClass = [plugin principalClass];
  if ([principalClass conformsToProtocol:myPluginProtocol]) {
[plugins addObject:principalClass];
  } else {
[plugin unload];
  }
  [plugin release];
}

My question is this (and the documentation, from what I've seen, is mute on the 
subject):  when an NSBundle object is deallocated, is its associated code 
automatically unloaded, or does it stay loaded in the runtime?

Thanks!

Dave

Re: Is this possible?

I either got no shadow, or a distorted image or the image went empty. Once in a

shadow instead it was the color of the original.

Well, I took the OP to mean just the opposite. Procedures often have to be
broken into two parts, esp. because of sheets; so, you might start out in
doMyThing:, but then you show a sheet and after the delegate callback you
want to proceed to doMyThingPart2:. Since the latter name is derivable from
the former, passing _cmd is a sensible way to generalize this situation, and
it's the exact opposite of a huge maintenance problem; provided the naming
convention is obeyed (a common enough pattern in Cocoa), pairs of methods
can be introduced or removed at will as development proceeds. m.

You seemed to have something that should work (creating a new image context, 
drawing the image with shadow, assigning that image to a UIImageView).

What didn't work about that?

This works because the selectedMenuItemColor is a pattern that happens to draw 
a gradient. You could just as easily draw nearly anything with a pattern, and 
Quartz treats patterns just like colors.

Persistent NSOperation?

[McLaughlin, Michael P.]

Could anyone point me to sample code that shows how to implement a
persistent NSOperation that could be enqueued repeatedly?

Currently, I initialize NSOps just prior to launching but this involves
copying large datasets (to avoid R/W contention) and it would be more
efficient if I could initialize a fixed set of NSOps just once and reuse
them.

In case it matters, I am targeting Leopard.

Thanks in advance.

No need, NSString's -compare:options: already handles mixed
alphanumeric strings like this when passed the NSNumericSearch option.

Hi Peter,

just got back to this issue after having to drop it for an urgent issue. A 
short recap: It seems the "winning" works for the space bar in Cocoa windows, 
but not for the arrow keys. In a Carbon window, neither of these keys get 
passed to the edit field, the menu items get triggered immediately. I've 
uploaded a short Cocoa test app with some Carbon and Cocoa windows and two menu 
items to http://dl.dropbox.com/u/34351/CarbonInCocoaShortcuts.zip. Just type 
into any of the text fields and then try to use the space or arrow key. You 
will get an NSAlert whenever the menu items get the shortcut instead of the 
text field.

It is sent from somewhere else than handleKeyEquivalent:, but maybe that's due

As an alternative, do you know if there is a way to find out what item (Carbon 
or Cocoa, both) really has the focus right now? If I had an 
NSView*/NSWindow*/NSResponder* or an HIViewRef/HIWindowRef, that I know has the 
actual focus right now, I could probably remove the menu item shortcut 
dynamically depending on what is focused.

freeing memory from an NSOperation

[Michael Thon]

Are NSOperations freed when they finish running or when the whole queue is 
finished?  My NSOperations seem to hang around, taking up memory even after 
they have finished their job.  At least, as far as I can tell using the Object 
Allocations instrument which shows them as living.  I am using an NSOperation 
with the garbage collector turned on, on Snow Leopard.  I subclassed main and 
put my computations in there.  When the NSOperationQueue is finished they no 
longer show as live.  Is this normal behavior?
Thanks
Mike

Version number objects

[Ken Tabb]

Hi folks,

I've got an app that needs to keep track of version numbers (eg.  
"10.6.2") of things, and needs to be able to sort by these too. Is  
there a class in Cocoa that handles this?


I could have sworn I heard mention of it in a previous WWDC (probably  
about 10.5), but all attempts at searching result in a load of pages  
pointing me towards Info.plist to get the version number :-/


The other people who I went with think I'm dreaming it...

If one doesn't exist, then I'm guessing doing an NSString subclass  
would be the order of the day (so that I can support / sort  
alphanumeric version "numbers" such as 10C540, or 1.0.1.2b), and then  
scanning for each period or change from number <-> letter, to break  
the version number down into its component parts (eg. so that 10C540  
ends up being {10, C, 540}?


Merry Christmas to all who celebrate it, and thanks in advance for any  
help you can give,

Ken

CSWeekView classes available

[David Hirsch]

A little while ago I posted a query here asking if anybody knew of a Cocoa 
class to create a weekly calendar, somewhat like the iCal week view.  Although 
there were a couple of promising replies, I decided to roll my own, 
"CSWeekView".  I've released it on GitHub under the LGPL.

For my program's needs, it was better to have it's orientation be horizontal 
rather than vertical like iCal.  Here is a screenshot of the result:
http://sites.google.com/site/csweekview/_/rsrc/1261385235599/home/SampleWeekView.png

And here is a demo app with the classes:
http://github.com/davehirsch/CSWeekView

I hope this is useful for other folks out there.

(Note that CS stands for ClassScheduler, the program for which I wrote the 
code).

Happy to give back a little,
Dave

P.S. I know there is much room for improvement, but this works, and seemed like 
a good place to get some code out there for others.

With "setCellSize:" you should be able to control the number of cell per row 
more easily.

Saving the whole view will be difficult because it's representation doesn't 
really exist. I mean the images not on the screen are probably not loaded, 
the layout is not computed and the backbuffer that stores the rendering is 
allocated only for the visible area of the view.

So if you want to create an image of everything you would probably have to 
iterate, scroll the view several times, do several snapshot of the view each 
time and to tile the images yourself (and also do all that in a separate 
offscreen window).

The snapshot part will be probably easier with a NSCollectionView yes.

Re: Localization strategies?

[Symadept]

Hi Ricky,

Even in my one of the project I am doing the same. Localizable.strings
(english) version shall have all the strings in Key-Value pair format,
"Hello" = "Hello"; And you can keep the comment on top of the string /*
Welcome text */.

And you can have many IBOutlets to set the string at runtime, as you
mentioned, with NSLocalizedString(@"Hello", nil). Now you generate various
language localizable.strings by Add Localization (mail me if you think you
need more info) from XCode and change the file format to UTF16. Now these
files shall still show you english. Now pass these files to Localization
team and they shall simply copy paste the other version of the string in RHS
of the corresponding files.

If you go with multiple nib files for various locale, UI maintainance will
become hectic. Hence you are in right track.

All the best.

Regards
Mustafa Shaik
