Re: What is a Delegate?

[dreamcat7]

Hi
Often people see "delegate method" in the Cocoa documentation and  
believe they cant use those ones because it requires a special object  
that they dont have.

However delegation is a very useful programming method.

Usually another developer writes a library class that requires a  
delegate to filling in the missing functions. Much like the idea of of  
asking you to write a callback function to fill-in the spaces that  
they cannot know. The delegate methods they ask for must each have a  
clearly defined purpose that is documented. They are called at  
convenient times on the 'partner' object which you (probably are  
already writing).


A delegate is needed for a persistent object that needs more  
information from you at an unspecified time, and well after the object  
was created / initialized.
And this allows the class to avoid having many or complex initializer  
(that may never be used). By contrast, a delegate method can be  
optional and simply ignored if it is not needed.


The best way to learn the concept delegation is to use the  
NSURLConnection class in synchronous mode. Another common class which  
should be attempted with delegation is NSTableView.  I strongly  
recommend to try either of these and then put a breakpoint in the  
delegate function.


The way a library class declares its additional delegate interface  
with the NSObject informal protocol. This is just a category extension  
of NSObject. So as long as your object is inherited from NSObject then  
you can implement these delegate methods.


@interface NSObject (ServiceProviderInformalProtocol)
// Delegate Methods
- (BOOL)serviceProviderWillRespondNextEvent:(ServiceProvider*)sender;
- (void)serviceProviderDidSetNextEvent:(ServiceProvider*)sender;
- (NSArray*)object:(ServiceProvider*)sender requiresMoreData: 
(NSData*)data;// If nil, the action will stop

- (NSComparisonResult)wasEqual:(ServiceProvider*)sender;

@end


If you implement a delegate method in your own object, the library  
class will try to call the delegate method when they require more  
data, when an event occur or to finish the job. Dont worry, in most  
cases the domumentation will tell you all you need to know.


So really when people talk about delegation in Cocoa they mean this  
callback interface and not a special kind of a niche object that you  
are required to write.
If you are migrating to Cocoa from another language, you may have seen  
this concept already, such as X-Windows API or Java @interface.

NSTableView bindings and current selection

[Jason Wiggins]

Hello all,

I have a tableView (showing query results) that has its values bound  
to an array controller; that works fine. I also have a NSPathControl  
showing the path of the selected item; this works fine too. I have  
implemented a right-click contextual menu to "Show in Finder..." the  
selected item in the tableView.
My question is, how do I get the path of the selected item so my  
showInFinderMenuAction: method does as it's supposed to do?
To be totally honest, even though I have got the menu working (it's a  
menuForEvent:theEvent method) and I can log the selected row  
correctly, I'm unsure of what to do next to implement the contextual  
menu.
As the tableView implements bindings, I can't see a way of getting the  
selected items row/column value, let alone that row's path reference.


Any help would be greatly appreciated.

Regards,
Jason

On Leopard (and possibly earlier–I haven't checked), it appears that the
string returned is actually a UUID created with the CFUUID functions
concatenated with the process ID and the result of mach_absolute_time() so
the result isn't a proper UUID. I'm not sure where the host name is coming
from; it's possible that the CFUUID functions incorporate it somehow.

The code makes no assumptions about starting off with an empty
document.  The only assumption it makes is that every document will
have at least one window associated with it, and that window is the
one you want to display the sheet.  All of this stuff happens in
response to a document being opened or an untitled document being
created.

Unless I made a glaring error in the code, that's what it's supposed
to be doing.  The document controller gets asked to open an untitled
document (-openUntitledDocumentAndDisplay:) or to open an existing
document (-openDocumentWithContentsOfURL:display:error:).  Since you
don't care about the first case, forget it exists.  The
MyDocumentController implementation of
-openDocumentWithContentsOfURL:display:error: invokes the super
implementation (which creates the MyDocument instance, adds it to the
document controller's collection, and displays it), and then it tells
the document to display its config sheet.  The document obliges by
starting a sheet attached to its first window ([self.windowControllers
objectAtIndex:0].window).

Hope that clarifies things a bit for you.

First thing's first. Documentation says return value should be:

If you don't like the string, you should not be returning YES. m.

One last correction: CFUUIDCreate() may return null, and one can't pass
null to CFRelease().  So an "if (uuidRef)" is needed.  (You can pass
null to NSMakeCollectable, but not to CFMakeCollectable).

NSTableView works in 10.5 but not in 10.4

[Ellen Chou]

I have a tree view window that uses NSTableView and NSOutlineView lists out
all the sub folders under user's home directory.  For some reason, this
window shows the folder contents correctly in Mac OS 10.5.2, but not in Mac
OS 10.4.x running on iMac which is PowerPC host running on Intel Duel Core
CPUs.

It seems to me the Notification/Event was not functioning properly in Mac OS
10.4.x iMac.  I don't get a chance to run on MacBook 10.4.x.  If any one has
MacBook Intel CPU running 10.4.x, please let me know.

Anyone run into the similar problem?

Thanks,
Ellen

Re: NSSpellChecker (foundation) broken for custom NSSpellServer servers

[Adam Strzelecki]

Don't want to hammer here too much, but I just want to have any  
feedback from Apple if this problem is known and if there's any chance  
to get it fixed.


I've already send some more details to Douglas Davidson month ago that  
provides here great support I see, but after that I haven't got any  
more word from him, too bad.


Maybe anyone else from Apple can have a look at this problem.

Just imagine how annoying it is when you write mails in two languages,  
and you need to restart Mail.app every time you change the spell  
checker language. And this affects all user that use CheckSpell or  
CocoaSpell, which are Universe minus AppleSpell provided languages  
only speaking ppl.


Below are details sent to Douglas:
Get me a copy of your spellchecker and instructions for reproducing  
the problem (including system version and configuration  
information) and I will take a look at it.



http://checkspell.apple.eu.org/ or direct download link 
http://web.mac.com/heidi17/Heidikowa_witryna/CheckSpell_files/CheckSpell-1.3.dmg

(The author of this service (software) is in the CC. I got direct  
contact with him as well. Please contact him if you need any  
information regarding the source-code.)


The installer will create /Library/Services/CheckSpell.service which  
is spell server based on NSSpellServer Cocoa API.
Once it is installed you should see additional languages such as  
Polski or Cestina. Let's try reproduce the bug with Polish<->English  
switching.


Try to open Mail.app and write new mail as below:

-
Here below is some Polish sentence.
Tutaj u góry jest tekst po angielsku.
-

1st line should be valid only in English (AppleSpell), 2nd should be  
valid only in Polish (CheckSpell).
Unfortunately when I start writing mail with English spelling,  
switching to Polish doesn't really make 2nd line valid, I get  
absolutely no response from Polish spell checker (probably  
AppleSpell called with "pl" instead of CheckSpell)


Then once the mail is saved and Mail.app restarted, it starts with  
Polish, everything is fine with the spelling (Polish this time),  
until switch back to English. Then CheckSpell is complaining that it  
is getting called with "en" language which it wasn't registered for  
(AppleSpell should be called).


IMPORTANT CLUE: When I do: "killall AppleSpell CheckSpell" prior  
running Mail.app, switching spelling languages works somehow fine!  
So the problem appears when AppleSpell & CheckSpell service  
processes are already running in the system. So the problem may not  
appear 1st time when you run Mail.app after installation of  
CheckSpell, please rerun it once both spelling service processes are  
running.


So the diagnosis is that once single application using  
Foundation.framework contacts the NSSpellServer that is already  
running, it will always use THIS one regardless of selected language  
and other NSSpellServer that may be proper.


Just as a reminder, I'd like to ask you (Apple) for focusing also  
the problem of revalidation of spelling on language change.  
Regardless of the bugs above, there is also slight annoyance with  
NSTextView based GUIs such as Mail.app that everytime you change the  
language in Spelling & Gramma window and you got Check spelling as  
you type ON the spelling is not revalidated with current language,  
you need to click Next many many times, or scroll your cursor trough  
whole document in order to make the spelling underline incorrect  
words in current language.
This is also the case when you open the saved mail in Mail.app,  
incorrect words are not underlined on open.



Opps forgot my configuration:

MacBookPro3,1 2.2GHz 2GB RAM, 250GB HD, MBP31.0070.B07

Mac OSX 10.5.4 w/latest security update, preferred language set to  
Polish, but I've also checked problem with English.


Problem appears since first time I've installed CheckSpell around  
Feb 2008 @ 10.5.2.


I got couple of friends that also has this problem with spell  
checker on other Mac computers.

Are you referring to a specific sample code?

Which notification/event are you referring to?

When there's a display strangeness in NSTableView/NSOutlineView, the  
first thing to check is that reloadData is called before at least once.

Your problem does not seem likely to be related to nib loading. There is no 
concept of "the current nib." Are you running a modal window/sheet, maybe?

SSCrypto to PHP

[Walter Johnson]

 Greetings,
 I need help with encrypting data to send to a php script to be
decrypted. I stumbled across the SSCrypto framework and I've been
using it to encrypt and decrypt a simple NSString. However, when I
attempt to plug this into my php script, it only outputs gibberish.
Can someone give me a hand here and perhaps guide me?
 Here's the cocoa code:
-
NSString * secretMessage = @"Hello World!";
 NSString * secretKey = MY_BF_KEY;
 NSLog(@"secretMessage: %@", secretMessage);
 NSLog(@"secretKey: %@", secretKey);
 NSData *seedData1 = [secretKey
dataUsingEncoding:NSUTF8StringEncoding];
 SSCrypto * crypto = [[SSCrypto alloc]
initWithSymmetricKey:seedData1];
 NSArray *ciphers = [NSArray arrayWithObjects:@"bf-cbc", nil];
 NSString *password = secretMessage;
 [crypto setClearTextWithString:password];
 int n;
 for(n = 0; n < [ciphers count]; n++)
 {
 NSData *cipherText = [crypto encrypt:[ciphers objectAtIndex:n]];
 NSString *cipherString = [crypto cipherTextAsString];
 NSData *clearText = [crypto decrypt:[ciphers objectAtIndex:n]];
 NSLog(@"Original password: %@", password);
 NSLog(@"Cipher text: '%@' using %@", [cipherText
encodeBase64WithNewlines:NO], [ciphers objectAtIndex:n]);
 NSLog(@"Cipher text as hex: '%@' using %@", [cipherText hexval],
[ciphers objectAtIndex:n]);
 NSLog(@"Cipher string: '%@'", cipherString);
 NSLog(@"Clear text: '%s' using %@", [clearText bytes], [ciphers
objectAtIndex:n]);
 NSLog(@" ");
 }
-
and the output
-
2008-09-08 14:25:50.925 tybit-blowfish[2588:10b] secretMessage: Hello
World!
 2008-09-08 14:25:50.927 tybit-blowfish[2588:10b] secretKey: pass
 2008-09-08 14:25:50.929 tybit-blowfish[2588:10b] Original password:
Hello World!
 2008-09-08 14:25:50.930 tybit-blowfish[2588:10b] Cipher text:
'nUYw6WbDs0M7NjXB6q6r2g==' using bf-cbc
 2008-09-08 14:25:50.930 tybit-blowfish[2588:10b] Cipher text as hex:
'9d4630e966c3b3433b3635c1eaaeabda' using bf-cbc
 2008-09-08 14:25:50.932 tybit-blowfish[2588:10b] Cipher string:
'ùF0Èf√≥C;65¡ÍÆ´⁄'
 2008-09-08 14:25:50.932 tybit-blowfish[2588:10b] Clear text: 'Hello
World!' using bf-cbc
-
Now, I take the cipherText encoded as Base64 (the line right below
'Original password') and plug it into my base-64/blowfish decoder in
PHP.
-
-
I know the base64 encode/decode is working properly because I can
successfully send and interpret data that is only base64 encoded. But
I want to add another layer of encryption to further secure the data.
Base64 is really only serving to allow the encoded string transport
over http.
 I can also vouch that the php code can successfully decrypt a
message encrypted with blowfish. I have similar code in another
script which reads encrypted data from a hex string delivered from a
windows application. So my concern is why won't it work with
SSCrypto/openssl? Any help will be much appreciated.

You can get the clickedRow of the table view, and use that as an index  
into the array controller’s arranged content. (Be sure to use the  
clicked row, not the array controller’s selection, unless you change  
the selection itself on the right-click).

Re: NSTableView bindings and current selection

[Corbin Dunn]

Hello all,

I have a tableView (showing query results) that has its values bound  
to an array controller; that works fine. I also have a NSPathControl  
showing the path of the selected item; this works fine too. I have  
implemented a right-click contextual menu to "Show in Finder..." the  
selected item in the tableView.
My question is, how do I get the path of the selected item so my  
showInFinderMenuAction: method does as it's supposed to do?
To be totally honest, even though I have got the menu working (it's  
a menuForEvent:theEvent method) and I can log the selected row  
correctly, I'm unsure of what to do next to implement the contextual  
menu.
As the tableView implements bindings, I can't see a way of getting  
the selected items row/column value, let alone that row's path  
reference.


Any help would be greatly appreciated.


In addition to what Ben said, please look at the DragNDropOutlineView  
demo app, which does this (albeit without bindings).

How do create a DMG with license agreement?

[David]

Hello,
I've seen many applications present a license agreement before their
DMG can be mounted. I read in the "Software Delivery Guide" about a
SLA for UDIF SDK. So I got the SDK. But its dated from 2003. Within
its documentation it says you need to use ResEdit and gives a location
of
http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English-North_American/Macintosh/Utilities/ResEdit_2.1.3.sea.bin.

However that turns out to be a classic application which doesn't run
on Intel machines.

Am I looking in the right place on how to add a license agreement to a DMG?

Thanks

You're looking in the right place, but IMHO, you're better off just  
forking over $20 for DropDMG, which does it all for you.

NSCharacterSet :+ (id)newlineCharacterSet

[Filip van der Meeren]

Hello,

I have the most puzzling question:

The documentation of XCode for NSCharacterSet includes the following:

newlineCharacterSet
Returns a character set containing the newline characters.

+ (id)newlineCharacterSet

Return Value
A character set containing the newline characters (U+000A–U+000D, U 
+0085).


Availability
Available in Mac OS X v10.5 and later.
See Also
+ whitespaceAndNewlineCharacterSet
+ whitespaceCharacterSet
Declared In
NSCharacterSet.h



But when I try to invoke this method I get the following:
warning: 'NSCharacterSet' may not respond to '+newlineCharacterSet'

And when I check the actual header file, the "+  
(id)newlineCharacterSet" declaration isn't to be found...


Is this a mistake on my side or Apples?

Thanks,

Filip vdm

[Aki Inoue]

The method was added to 10.5.

So, if your project is not targeting 10.5 and later, you get the  
warning.

On my 10.5.4 system, this appears in the NSCharacterSet.h header:

#if MAC_OS_X_VERSION_10_5 <= MAC_OS_X_VERSION_MAX_ALLOWED
+ (id)newlineCharacterSet;
#endif

Bundle Load Fails for Users with G3 Processors Only

[Jerry Krinock]

My app works fine on an Intel Mac running 10.5, and on my old 800 MHz  
Powerbook G4 running 10.4.11.  But after the latest update I received  
complaints from two users with G3 processors.  Upon investigation, it  
turns out that the message


   -[NSBundle classNamed:]

logs an error [1] and returns nil instead of loading the bundle and  
returning the requested Class.  If I didn't know better, I'd say this  
is an apparent case of insufficient hardware to load needed  
resources.  But, duh, that's supposed to be impossible with virtual  
memory.


One user has an iBook with a 800 MHz G3 processor and 640 MB RAM.  The  
other has a "Paris" Clamshell iBook with a 466 MHz G3 and RAM maxxed  
out at 512 MB.  She says it's "the oldest iBook that can run OS X".


Now, the user with the 800 MHz iBook has been using my app for over  
two years.  Also, I myself have run previous versions of my app on my  
old 500 MHz G3 iBook with 320 MB RAM, 10.4.?, and it worked.  (But I  
have since downgraded that puppy to 10.3.9, and my app does not try to  
load the problem bundle under 10.3.9.)


It looks like something got changed in the latest build that G3  
processors don't like.  Any ideas what that might be?


Jerry

[1] The error is:

*** -[NSBundle load]:
Error loading code /Applications/MyApp.app/Contents/Resources/ 
BmTiger.bundle/Contents/MacOS/BmTiger

for bundle /Applications/MyApp.app/Contents/Resources/BmTiger.bundle,
error code 4
(link edit error code 4,
error number 0 (
Library not loaded:
@executable_path/../Frameworks/SSSQLiter.framework/ 
Versions/A/SSSQLiter


which says that the SSSQLiter framework will not load, but I checked  
and it ^is^ at the promised path, and ^is^ a universal binary, and of  
course this all works fine on my Powerbook G4.  MyApp's package  
structure:

That's easy; after you change your model. When do you initialize your  
arrays, etc? After that point, call reloadData. Possibly in - 
awakeFromNib.


If it is working by chance on Leopard, then it is probably because of  
some ordering issue that changed slightly.

Crash in NSOpenPanel. Garbage collection thread

[David]

I've found other reports of NSOpenPanel crashing with garbage collection,
but I haven't found a workaround.
Does anyone know what scenarios cause this? It appears random or timing
dependent, but is a serious issue.

It happens in my application sometimes frequently, sometimes not.

With this current crash, the NSOpenPanel showed up except without listing
any files, then it crashed.

exit. MyThread is a simple NSThread subclass. No custom input  
sources or

timers are registered with the run loop. Unless I misunderstand the
documentation or there are some 'hidden' input sources or timers are
registered with the run loop, I would expect 'run' to exist  
immediately.

Would much appreciate help with sorting this out!

Thanks,
Roman Kishchenko

@implementation MyThread

- (void)main {
   NSLog(@"++ start");
   NSRunLoop *loop = [NSRunLoop currentRunLoop];
   [loop run];
   NSLog(@"++ finish");
}

This has come up before several times on this list over the years, so  
there are a few answers already in the archives.  But I have an idea  
for a new way to explain it.


The documentation is correct.  However, it's trying to warn you that  
the method *can* return, not explain how to get it to return.


The mistake people make is in assuming that they control the contents  
of a run loop (or even a run loop mode).  However, the run loop is a  
global object, accessible to all code run on that thread (and perhaps  
other threads if you squirrel away a copy of the pointer somewhere).   
In particular, all frameworks that you call into, directly or  
indirectly, may access it and do things to it, including putting  
things in it.


I think you are intuiting exactly this when you mention "custom" and  
"hidden" input sources.


Try the -run...BeforeDate: method in a conditional loop if you want  
block in the run loop most of the time, but want to bail under some  
conditions (which would then be the test of the loop).

Re: How do create a DMG with license agreement?

[David]

Is it just me or should an Apple operating system facility have a
public API rather than apparently a non-published API?

Are there many things in the Mac world with unpublished APIs where you
have to rely on 3rd party tools to access operating system functions?
Or is the DMG format unique because of some legacy issue?

Thanks

The reason creating a DMG _with a license_ is such a PITA is a legacy  
issue. It's still documented though.

PowerPC 7400 is targeting G4 or G5 processors only.

What target SDK and target OS is the project configured for? IIRC
specifying a target of 10.5 for both enables the use of ppc7400 for
ARCHS (or in theory it coudl...). ...or maybe you have AltiVec
enabled?

Yup.  Although my Target's architecture setting was the generic "ppc

MacOSX10.4u.sdk to MacOSX10.5.sdk.  Since Leopard won't run on a G3,  
gcc decided to change the product's architecture to ppc7400.  Changed  
it back to 10.4u, rebuilt, and now lipo gives the correct answer of  
"i386 ppc".


Thanks, all.  So I've learned another near-obsolete fact today.  Oh,  
well.

Finding out in code how much memory my application uses

[Aaron VonderHaar]

Hi,  I am trying to write some automated scenario tests that verify
that my application meets it's the memory usage constraint
requirements.

What API is available to find out how much memory an
application/process/thread has allocated?

I have looked at the documentation for NSZone, NSProcessInfo,
NSThread, NSAutoreleasePool, NSTask, NSApplication, the "Interacting
with the Operating System" guide and the "Memory Management
Programming Guide for Cocoa" guide but I have not found any
information about how to find out the number of pages, bytes or
objects that are in use.

Has anyone accessed this type of information in their own programs?

Re: Finding out in code how much memory my application uses

I would suggest using the DTrace stuff... either using instruments or  
using DTrace scripts directly... there is tons of good information  
about DTrace at google.


You can also look at /usr/include/mach directory for various mach  
calls regarding process statistics, including memory usage (all the  
stats can be grok'd from there including phyiscal memory used, virtual  
memory used, wired memory used as well as faults and other memory  
info)...

First thing's first. Documentation says return value should be:

YES if the value in the string parameter should be accepted as is;  
otherwise,

NO if the value in the parameter should be rejected.


If you don't like the string, you should not be returning YES. m.


You're right I should have read that part of the documentation.  
However, I had tried returning NO, and it didn't really help.


If I return NO, not only do I get my error displayed, but the standard  
error dialog is also shown. Which suggests that the return value is  
overloaded with a "I have handled this error" meaning. This is backed  
up by the following page that I read:


  ://initgraf.blogspot.com/2007/11/customizing-errors-generated-by.html

Where it says, "You need to return YES, or else you'll get both your  
custom error and the standard error."

While we're on the subject of DMG's for software distribution...

[Chris Markle]

Hi Folks,

(Not super saavy about Mac OS X here so bear with me please...)

On the subject of DMG's... I inherited a software product that
currently ships using some moldy-oldy version of the Wise installer. I
think basically all it does is put the application _folder_ into the
Applications folder. In the application folder I am referring to is
the application bundle, some PDFs (doc) and a Plugins folder with one
plugin bundle in it. I think the application expects the plugins to be
in this specific place i.e., the Plugins folder in the applications
folder.

I'd prefer to ship this as a DMG... But if I understand DMG-based
delivery correctly, the idea is that Mac users are used to this and
"know" to copy the application bundle to the Applications folder. But
I need the user to copy the application folder (not just the bundle)
into the Applications folder. otherwise the plugin won't be found and
life as we know it will cease ;)

Is DMG just a non-starter for this or is there a way with a DMG format
to someone clue in the user that the folder needs to be copied, not
just the application bundle.

Thanks in advance...

Chris

Re: While we're on the subject of DMG's for software distribution...

[David]

I'm certainly no expert but...
Application bundles are just directories which some special
characteristics that makes Finder hide the fact that its a directory
to make it look like an application. Finder just looks at any
directory that ends in .app and thinks its an application. It then
looks inside for an application, but in anycase, it doesn't show the
user the directory as a directory.

If the files you need are shipped as part of the application, the
appropriate place to put them is somewhere within the application
bundle (directory).

If the files are added during runtime or after installation, then they
typically go in the user directory in ~/Library/Application
Support/programName.

Some of this is spelled out in "File System Overview",
http://developer.apple.com/documentation/MacOSX/Conceptual/BPFileSystem/BPFileSystem.html

Yes here: http://developer.apple.com/sdk/

Look for: Software License Agreements for UDIFs (DMG), it says:

Mac OS X's Disk Copy has the ability to display a multi-lingual  
software license agreement (SLA) before mounting a disk image. This  
SDK explains how to add license agreements to Mac OS X-native UDIF  
disk images.



And you can download it here:



However, I think the OP's point was that the SDK - while it describes  
what you need to do in order to get this into your DMG - offers no  
tools or help to actually do it, it just outlines the major steps  
involved.

Re: SSCrypto to PHP

[Jerry Krinock]

Hello Walter,

Since your message has been languishing for over 8 hours now I figured  
that my two cents might be better than nothing.  I spent a few minutes  
reading your code but got too confused.  Example:



NSString *password = secretMessage;


Seems weird to set your password equal to the message.

Anyhow, assuming that you've done all this for good reason, you have  
to realize that you're dealing with some pretty poorly documented API  
there, OpenSSL and SSCrypto.  I recently had the fun of creating an  
RSA signature using Perl's OpenSSL wrapper and verifying with the  
openssl library in my Cocoa app.  It took a day or two of guessing  
before I got it working.  The only advice I can give is to not assume  
anything, doubt the documentation, watch out for hidden hash  
functions, try to strip your code down to the barest essential and  
don't be afraid to poke around inside SSCrypto.

You can set the background image of the dmg to explain it, but some  
users will not do what you say and manually copy it incorrectly.


Your two options to ensure correct installation would be to:
a) use a package installer
b) put the plugins and docs inside of your application's bundle.

The documentation doesn't specify any particular format for the string
returned, only the information used to seed it---I wouldn't recommend
depending on this method always returning a UUID incase this changes
(even though it probably won't).

My recommendation for this would be:

1 Put the PDFs in the Resources folder in the app, and add Help menu 
entries to display them.


2a Put the Plug-Ins folder in the Contents folder in the app and use 
it from there; OR
2b Put the Plug-Ins folder in the Resources folder, and on launch 
copy it in to ~/Library/Application Support/Your App Name/Plug-Ins

Pro Tools does this.  It's incredibly frustrating to have to launch
the app just to get at the documentation.  I happen to know that you
can open the app bundle, but who is to expect that a normal user will
know?

This makes sense, because you can then use -[NSBundle
builtInPlugInsPath] to get to them.

This isn't helpful to the user if they want to move or copy the
application.  The OS does a good job of presenting the user the
appearance of a monolithic application object.  Granted, your plug-in
might rely on code that gets installed elsewhere, so this might not
matter.  But, for example, I expect that when I add Dreamweaver
plugins, like the very important updated WebDAV plugin bundle, that I
can move the app around and not lose it.

Better yet, search not only in the bundle but also in a few other
sensible locations.

ZIP files don't get the special treatment Internet-enabled DMGs do.
For one, if your Internet-enabled DMG only contains your app bundle,
Safari will unwrap the executable and throw away the DMG.  Also, it is
a very convenient wrapper for holding things like documentation,
uninstallers, etc.  I can also very easily burn a CD from the DMG --
very important as I found out when I accidentally trashed my network's
repository of software.

According to the documentation
(http://developer.apple.com/documentation/Cocoa/Conceptual/LoadingCode/Tasks/LoadingBundles.html#//apple_ref/doc/uid/20001273-99488-BAJFBAJB),
PlugIns is correct.  Plug-ins is used as a fallback.
