Re: Code signing checking

[Stephane Sudre via Cocoa-dev]

Is this to prevent your executable from loading plugins that are not signed
with your team ID?

Because, in this case, this would look like what the Hardened runtime does.

Re: /Library/Application Support off limits?

[Stephane Sudre via Cocoa-dev]

I'm not sure to understand why you think a folder whose path is
/Users/Shared could not be used to share things among users.

If the issue you see is that once a user creates a file or directory
in /Users/Shared, only this user can manipulate them, just change the
POSIX permissions to make them editable by other users.

NSCollectionView + custom layout => missing vertical drop line

[Stephane Sudre via Cocoa-dev]

I'm currently playing with NSCollectionView (10.11+ behavior) and have
not been able to figure out a mystery when it comes to drag and drop.

I have a NSCollectionView with a custom layout.

The layout is based on the standard grid layout with the following
modifications in mind:

- there can only be one row.
- there are as many columns as items.
- the collection view can be scrolled horizontally.
- the width of the items is fixed.
- the height of the items is the height of the contents.

The mystery I'm facing is that during a local drag and drop (to switch
items), the vertical line indicating the target of the drop does not
appear.

The mysterious side here is that if I change the maximumNumberOfRows
to 0, it does appear but I lose the horizontal scrolling.

Since this is the first time I try to use the NSCollectionView class
with a custom layout, I'm probably doing something wrong. But I have
not found so far an obvious solution from the miscellaneous tutorials
here and there.

So if anyone has an idea what's wrong, I'm interested.

Sample project:

Warning: the drop indexes are computed incorrectly for the moment.
Dragging and dropping the first card between the second and third ones
is safe.

Re: Curious bug in oPanel under Mojave in screensaver

[Stephane Sudre via Cocoa-dev]

It's a known issue in all 10.14 versions and some 10.15 versions.

Apple broke NSOpenPanel when they sandboxed the screensaver pref pane.
They also broke window focus BTW.

2 issues can be observed:

- you select a file, you get the parent folder.
- you switch to the list view mode and you can freeze/crash the System
Preferences application.

Basically, 10.14 and 10.5 have been huge nightmares when it comes to
screen savers.

I'm just reading Swift code here and there and it's my personal
opinion that 75% of the Swift code I read is bad code.

By bad code, I mean code suffering from the "only God and I know what
I'm doing" syndrome.

The same syndrome that you can find in software using Cocoa bindings.
The same software that is terrible to maintain, even more when you're
not the original author (and you're obviously not God).

Why do Swift developers think it's mandatory to write code that is illegible?
Is Swift mainly used by freelances or consultants that will not have
to maintain the software?

Cocoa source code is not really hidden if you use the proper tools and
know how to use them and that you should not rely 100% on them.

With Hopper Disassembler, you can see any Obj-C framework source code
in /System/Library/(Private)Frameworks.

Although most of the time you don't need to see the source code, there
are some areas that are poorly covered by the developer documentation
and being able to see the implementation details is very useful. For
instance, if you ever had to write a custom subclass of NSCell or a
subclass of NSControl with multiple cells, the official documentation
was almost totally useless and this was a good opportunity to find out
about the private API Apple was keeping to itself to make the AppKit
controls work.

It's true that having access to the source code can also help finding
issues and suggesting patches. But it's also true that if Apple had
been doing a proper job at checking the warnings and static analysis
outputs of its own IDE, numerous issues could have been fixed without
having needed to be reported by 3rd party developers.

If you combine otool, classdump and Hopper Disassembler, you can find
how some Cocoa methods are working in any Obj-C executable pretty
easily.

https://www.hopperapp.com

http://stevenygard.com/projects/class-dump/

Checking cocotron can also be helpful if you want to see how someone
else implemented most Foundation and AppKit legacy APIs.

Re: Screensaver icon ?

[Stephane Sudre via Cocoa-dev]

For the record, due to Apple's inability to support 3rd party screen
saver seriously, the custom icons for 3rd party screen savers are
displayed incorrectly and differently depending on the OS versions.

So don't spend too much time on getting your screen saver icon to be
pixel perfect. The Desktop and Screen Saver pref pane will always do
its best to ruin it.

Re: Carbon -> Cocoa

[Stephane Sudre]

It might be the new Carbon once:

- there is ABI stability in Swift. This could be not before late 2019.

- the new APIs are only available in Swift. Is Swift NIO a hint this
is coming sooner than expected? I don't know. I don't use networking
frameworks.


Regarding the complexity of porting from C++ Carbon to Cocoa, there's
also the important question of what your minimum OS target is.

Maybe one of the reasons why you kept a Carbon version alive so long
is that the application needs to keep working on older OS versions.

Porting to OS X 10.10 or later is not the same thing as porting to
10.6 or later for instance.

Re: Detecting if current user owns the screen (screen lock/FUS)

[Stephane Sudre]

SystemConfiguration.framework?

You can:

- retrieve the current uid,gid, user name with SCDynamicStoreCopyConsoleUser
- be notified via a C callback when the console user changes
(SCDynamicStoreCreate, SCDynamicStoreKeyCreateConsoleUser(),
SCDynamicStoreSetNotificationKeys, SCDynamicStoreSetDispatchQueue or a

SCDynamicStoreCopyConsoleUser.

Note that when the login window is displayed, the current user name is
"loginwindow".

I've never checked which uid or user name was returned when the screen
is locked.

Yes, there is.

In both cases, if you are not happy with the Column Sizing option
(respectively Last Column Only and Uniform), you can always enumerate
the columns of the table view and set their width as you like (by
registering for the NSViewFrameDidChangeNotification notification of
the appropriate view). You need to take into account the
intercellSpacing.

Re: Getting/Setting FinderInfo attributes using native Cocoa API?

[Stephane Sudre]

Actually, it's to put back some of them on a newly created folder. So
right now, it just retrieves the values as NSData objects but I've
added a hook to be able to convert the data to the real objects.

the - [NSFileManager copyItemAtPath:toPath:error:] API does copy at
least the FinderInfo and ResourceFork extended attributes (which are
the ones that I need). I haven't checked whether it was copying the
quarantine flag or the download history ones yet. So depending on your
needs, you may not need to use the copyfile API.

Re: Getting/Setting FinderInfo attributes using native Cocoa API?

[Stephane Sudre]

I ended up writing a category for NSManager to deal with this using
the xattr.h APIs.

Something like:

- (NSDictionary *)PKG_extendedAttributesOfItemAtPath:(NSString
*)inPath error:(NSError *__autoreleasing *)outError;
- (BOOL)PKG_setExtendedAttributes:(NSDictionary *)inExtendedAttributes
ofItemAtPath:(NSString *)inPath error:(NSError *__autoreleasing
*)outError;

Re: Getting/Setting FinderInfo attributes using native Cocoa API?

[Stephane Sudre]

No specific attributes in the FinderInfo data. I just need to be able
to get it and set it on another file/folder.

The labels case you mention is an interesting one. I had not thought
about it when it comes to cross-compatibility with the different OS
versions I need to support.

Getting/Setting FinderInfo attributes using native Cocoa API?

[Stephane Sudre]

Question:

Is there a native Cocoa API that can replace the
FSGetCatalog/FSSetCatalog API when it comes to retrieving/setting the
FinderInfo (and FinderExtInfo) attributes of a file?

OS X 10.8 and later.

Problem:

The FS CoreCarbon APIs are deprecated but apparently, there's nothing
to replace them completely in Cocoa (Foundation).

The NSURL resources APIs does not support the FinderInfo attributes
(no obvious key in the broken documentation and using
"com.apple.FinderInfo" does not work).


Workaround:

This can be worked around by using the xattr.h APIs but if it could be
possible to avoid this, it would be better.

Re: Class is implemented in both

Regarding the solution that requires to change the name of the class

It would require to change the name of the renamable classes (and

IMHO, it depends on how your produce is distributed:

- if you're distributed it via an Installation package and the
components are installed in /Library, you could use a Framework with
the shared class and install it in /Library/Frameworks (and of course
use the framework in both your Pref Pane and Screen Saver module).

- if the installation is supposed to be done manually or with the user
double-clicking the Pref Pane and Screen Saver module to get the OS to
install them either for all users or the current user:

. you could redefine the class name in the .pch of one project.
- you could rename the class after one of the 2 projects has been
built and then codesign the new binary. Basically, you scan the
executable binary for the name of the class and you replace it with a
name of the same length. I'm doing this for screen saver modules who
share some code which is within a submodule.
- you could parse the Mach-O executable file and parse the appropriate
sections (__objc_classname, __objc_classlist, etc.) of the appropriate
segments (__TEXT, __DATA, __OBJC)  (which depends on the Objective-C
version for instance) to find your class name and replace it with a
unique name (again same length unless you're looking into rebuilding
the entire Mach-O).

  e.g. __DATA, __objc_classlist contains 64-bit references to struct
objc2_class_t records in __DATA, __objc_data. The data record of such
a struct will point to a objc2_class_ro_t record in __DATA,
__objc_const and the name record of this struct will point to the name
of the class in __TEXT, __objc_classname.

[NSXPCConnection] Getting the effective user/group ids of the listener

[Stephane Sudre]

It's possible to retrieve the effective user/group ids of the remote
peer from the listener delegate method.

But it there a way for the remote peer to get the effective user/group
ids of the remote listener?

According to the CREDENTIALS section of the xpc_objects(3) man page,
it seems to be possible but even after a message has been exchanged
the values are still -1 and -1.

Re: Thoughts on autolayout

I tend to believe that it's because of step 4 that some developers

Not using autolayout is an even better experience so far for me because:

- autolayout was released when it was not ready and so while it's
supported on some earlier OS X versions, it does not work correctly on
them: slowness, different behaviors depending on the OS release, etc.

- autolayout still seems unpredictable when you think to have
understood how it works and some error messages are written in
Klingon.

- for simple cases, autolayout is not simpler than resizing masks. For
complex cases, it's more complex and time consuming than writing the
layout code to deal with these complex cases.

- you still have to use intermediary subviews to deal with complex cases.

The only thing that isreally missing with resizing masks isthe ability
to center a view vertically or horizontally in its superview.

I must be missing something but why should there be an API?

- determining whether SIP is on requires to check whether the running
OS on 10.11 or later. Also it could done by parsing the output of $
csrutil status but this would assume the output format will not change
in the future.
- determining whether you can write to a file or folder can be done
with the usual BSD, Cocoa APIs, can't it?
- knowing which parts of the file hierarchy are protected is covered
by the documentation (Interestingly I've just discovered that
/Applications/Utilities is a no trespassing area).

IMHO, it would just be cleaner both from a code and architecture (MVC)
point of view. Because the final target of your action is not the menu
item.

Usually, the FirstResponder object would be the target of the menu
item action so that if you implement the action in your window/dialog
controller or in another potential first responder in the dialog, the
menu item will be enabled (even without a validateMenuItem:
implementation).

Which feature of a modal window are you looking for? Because having
all the menu items being enabled in the case of a modal dialog does
not match the nature of the modal mode (i.e. restricted mode).

> Each menu item has itself as target and a method to respond to the action.

Why not have at least a shared object as the target?

> If I only change from runModalForWindow to a non-modal window show,

It's possible to have (enabled) menu items for a window running as
modal. For instance, if you have a NSWindowController subclass
controlling an empty modal window panel, you can add a - (IBAction)
cut:(id)sender {} method to the controller and the Cut menu item will
become enabled.

Re: Will iOS app accepted on App Store if 80% of UI is rendered on UIWebView and 20% being native OCR

[Stephane Sudre]

From your description, your app would use official APIs. So in theory,
it doesn't matter if your app is just presenting a web view (like a
lot of apps).

But considering that the interpretation of the App Store Guidelines
can vary depending on the reviewer or the weather forecast, the only
way to know if your app will be accepted is to submit it to the review
process.

 Now I want to integrate OCR capabilities such as:

  1. ID card scan
  2. Debit card scan
  3. Void check scan

 So that some of the forms can be automatically filled by information
 extracted from these.

 I am planning to make a native app in iOS consuming most of the forms, flow
 from my mobile website by rendering respective weburls on webview, and
 integrating vendor SDKs to provide OCR capabilities.

 Will Apple accept my iOS app in App Store if I have 80% of flow, UI
 rendered on UIWebView and remaining 20% being integration and use of native
 vendor SDKs for OCR capabilities?

Auto-layout in (too) many cases is no gain, lots of pain.
Considering the issues (e.g. performance) with the earlier versions,

more if Storyboards are included.

It can depend on how much code you have that is toll-free bridging
CFSomething and NSSomething.

 One thing we both forgot to mention is blocks — I can’t remember, can you 
 even use blocks in an app targeting 10.5?

Nope. 10.6.

Regarding the things you forget to mention is GateKeeper v2. AFAIK,
this requires to build (or at least codesign)  on OS X 10.9.5 or
later.

If your build system is your development system, then this imposes a
minimum Xcode version and so a minimum SDK version. IMHO, it's easier
to develop with a OS SDK version that is close to the target OS
deployment version. With 10.9.5, you probably need Xcode 5 or later,
which could mean a 10.7 SDK or later. So if you're targeting 10.5 or
10.6 compatibility, you may end up with some surprises during
development and testing regarding the available APIs.

Re: Updating a screensaver from 10.6 to 10.10

[Stephane Sudre]

• You may also need|have to consider moving away from Garbage
Collection. 10.10 (or 10.11?) is the last version to support it.

• You need to codesign the screen saver on 10.9.5 or later, otherwise,
it won't be GateKeeper v2 compatible and the user won't be able to
double-click it in the Finder to install it in the now hidden
~/Library/Screen Savers folder.

• You may need to consider providing Retina compatible image resources.

• If you want to provide a thumbnail preview to be displayed in the
Screen Savers Pref Pane list, you can add 2 PNGs in your .saver
bundle: thumbnail.png and thumbn...@2x.png. (3)

• Depending on the age of your code source, you may also want to start
using a NSWindowController for the configuration sheet of the screen
saver module.

• When it comes to detecting the main screen, it depends on your
definition of the main screen. The mainScreen method returns the
screen containing the window with the keyboard focus, this may not be
the screen with the menu bar (1) (2). It's usually easier to identify
the screen with the menu bar as the first screen in the array returned
by screens.


I'm currently updating a few OS X ports of Windows Screen Savers. I'm
using mostly the same templates for all of them. Just in case, you're
looking for a template:
https://github.com/packagesdev?tab=repositories


(1) Of course, since the menu bar can be displayed on every screen in
recent versions of OS X, this can be even more confusing.
(2) Considering the menu bar is not displayed when the screen saver is
running (i.e. not preview mode), this is not really a definition of
the main screen either.
(3) Due to bugs and lack of commitment from Apple, the rendering of
one's thumbnail preview is not really good in recent OS versions. I'm
getting not too catastrophic result using this project:

https://github.com/packagesdev/screensaverthumbnailfactory

It currently requires to complete the windowDidLoadMethod of the
SSTFWindowController class to call showScreenSaverForBundle: with the
appropriate bundle for your screen saver.

 Does anybody know of some guidelines , or a list of hints, or any other

 In particular, I'd like to learn more about the changes needed in 
 CoreAnimation, in Scripting Bridge to retrieve photos from iPhoto-now-Photos,
 and the way I identify the current display/monitor.
 Below are a few code snippets, for your information.

 And I am interesting in anything else you might deem worthy of upgrading in 
 the source code.

 Thanks a lot in advance.

 [CATransaction begin];
 if ( crossDissolve_ )
   [CATransaction setAnimationDuration: fading_duration];
 else
   [CATransaction setValue: (id)kCFBooleanTrue forKey: 
 kCATransactionDisableActions];

 Code snippet I used to identify monitors/displays (this seems to fail since

 displayNumber_ = [ [[newWindow screen] deviceDescription] 
 objectForKey: @NSScreenNumber];
 displayID_ = [displayNumber_ unsignedIntValue];
 unsigned int main_screen_id = [[ [[NSScreen mainScreen] 
 deviceDescription] objectForKey: @NSScreenNumber] unsignedIntValue];

 I suspect , this code does not work any more as intended, because I get often 
 a new display ID for exactly the same monitor (just a cinema display).

Another solution: use Objective-C.

 It’s already done in Swift 2. While you’re editing in the one pane, the

Maybe I misinterpreted the presentations, but this is not a property

What do you consider to be the icon for the screensaver?

The icon that is shown in the Finder for the .saver file or the the
thumbnail preview you see in the Desktop  Screen Saver Pref pane?

Unless I'm mistaken, for the first one: it would require to add a
custom icon either via the Finder Info Window or via a script.

For the second one, you need to have thumbnail(@2x).(png|tiff)
images in the Resources (90x58, 180x116).

Re: Extrange problem with screensaver in 2 monitors and key stroke

If you are subclassing the keyDown:|keyUp: method of the screensaver
view, you are limited by the fact that there can only be one first

A solution could be to post a notification when you detect the N key
being pressed (or released) and refresh the Web View from the
notification observer callback.

 Was I clear describing the problem? I'm kind of lost. I don't know where to

You will have a cell (NSCell in the project I used to check) in the

 Although you are correct (a running application is indeed an 
 application), your bug should ask that the 
 NSWorkspaceDidTerminateApplicationNotification *documentation* be clarified, 
 because, as Peter Ammon confirmed, it's way too late for Apple to change the 
 behavior.

Yes, that what I'm going to do. I will also suggest to add a comment

[BUG?] LSUIElement=YES and NSWorkspaceDidTerminateApplicationNotification

[Stephane Sudre]

Is it a known bug that the
NSWorkspaceDidTerminateApplicationNotification notification is not
sent for applications whose LSUIElement key is set to YES?

I've found an entry for this in StackOverflow but the explanations
provided to the original poster are forgetting the LSUIElement factor.

 The *behavior* is known, at least by me, and is as you say, Stephane.  The 
 question is: Does Apple consider it to be a bug?

 The documentation of NSWorkspaceDidTerminateApplicationNotification states 
 that it is posted when an application finishes executing.  Is an 
 application running with LSUIElement considered to be an application?  
 Unfortunately, NSWorkspace documentation throws out the word application 
 like that in quite a few places without a precise definition.

 This is likely one of those cases where it would be safe to assume that Apple 
 will not change (fix) the behavior, because to do so might break apps 
 expecting the old behavior.

 Have you filed a bug on this and has there been any response?  If not, I'll 
 file one because I too use this notification and would at least like the 
 behavior to be properly documented.

 What am I doing wrong?

AFAIK, you can't save a NSURL instance in the defaults/preferences of
an application using a NSDictionary or NSArray that contain a NSURL
object. You have to use the setURL: forKey: for it work.

Personally, I've given up thinking about using NSURL in defaults for a
screen saver and just use a NSString with the absolute path.

Does this restriction work for the screencapture command line tool?

 When a customer adds my app to Login Items in System Preferences it

For the each of item in the Dock:

1. ctrl + click on the item
2. Choose Options  Show in Finder

It will probably show 2 different instances (locations) of the application.

 If you never ever submit apps to the app store, or you have your own managed 
 app store and develop apps solely for the enterprise, and never mass market 
 apps, then be it on iOS or Mac OS, you are expected to have access outside of 
 the sandbox.  It is expected that you will have access to the device and 
 different folders to create useful software.

I don't see why you have to care about the Sandbox in the case you
describe. The only issue there could be so far at that time is you
would have to codesign/productsign your application/installation
packages for 10.8 and pay the Gatekeeper rent.

Moreover, Gatekeeper is so easy to work around when you have control
on the way your application is deployed (which you seem to have in the
case you describe) that you could even get away without
codesigning/productsigning your products for OS X 10.8.

 Since the docs are voluminous, could anyone suggest where I should start

I would tend to believe that you should do what BugReporter requires

 You'll need to build with the 10.7 SDK that comes with Xcode. You can still

It's allowed. IIRC, when the helper app is launched from the main

 I thought (and I'm barely getting up to speed on this) if the program was 
 launched as an NSTask, it would inherit the entitlements  container of the 
 parent. If it was launched as an XPC service it would have its own 
 entitlements and container.

 But… if the program is launched from a Terminal window or by launchd (e.g., 
 scheduled to run at midnight), what then?  Does it run like a normal UNIX 
 program with no sandboxing?  What if this UNIX helper app is copied to a 
 different directory?  Does Apple forbid a program from MAS that can be 
 launched this way or if the developer induces its users to run it this way?

I would believe this is the same case as for code-signing. Every
executable must define its entitlements.

Re: How to set the foreground and background colors of selected text in a field editor (NSTextView)?

[Stephane Sudre]

Interesting problem.

I'm afraid one of the easier solutions is to use a NSTextView instead
of a NSTextField. When you set the selectedAttributes of the field
editor, I believe it will be forgotten as the field editor will try to
mimick the way the text look like when not edited, (Sure the doc says
these attributes are OK but they are for the NSTextView that will be
edited AFAIK).

Allowing rich text, subclassing NSTextField and add some methods from
NSTextView did not work so far. No obvious private API for this in the
AppKit.

editor. The issue is that you're not editing this NSTextView, you're
editing the NSTextField.

At least that's my take on this.

Re: TextView cannot Use Selection for Find

 Same for Find Next and Find Previous.
 (Edit → Find → has these commands grayed out).

 Using Find Bar or Find Panel makes no difference. Making it editable or not 
 also not.

 How can I make this work? I have used NSTextView many times before, and they 
 just did work.

 10.7.3, Xcode 4.3.2.

It looks like it beeps when there is no active selection or when the
textview is not the first responder.

Might be worth checking if you don't have some validateMenuItem code
disabling these menu items too.

Re: What to use instead of operatingSystemVersionString

If this is an AppKit related bug then you could check the

Re: Localization for nibs

 Hi,
 currently my application supports only English. In the future versions we 
 would like to have it in around 15 languages.

 What is the best practice for having localized nibs.

 1) Common approach, different nibs for different languages.
  +ve, straight forward.
  -ve, Time consuming and maintenance effort.
 2) By using Auto layout feature.
  +ve, available only in Lion
  -ve, not in Leopard and Snow Leopard

Some things that could be useful to make your decision:

- When in Rome, do as the Romans do: check what Apple does. As far
as I know, they are still localizing with multiple nibs.

- Check what the guys who will localize the software would rather use.
The localization solutions based on just localizing the strings have
some side issues:

  - you absolutely need to provide context information for all the strings.

  - you generally end up with duplicates in your .strings files (e.g. DL2).

   - it's more difficult to adjust the layout for specific
localization requirements.

   - you absolutely need to provide a working binary, otherwise it's
not possible to do any kind of check.

- With .strings only localization, you're adding code to handle
something that can be done without additional code.

 When I try it again after some time - it is slow again.

 Is this a known problem? If so, what is the reason?

It can happen also if a secondary disk is in sleep mode.

 As the code for TextEdit is on my disk, I am thinking of investigating this.

Is the source code for the recent version of TextEdit available? I

 Can someone enlighten me whether / how it would be possible to distribute a

 What I would like to provide via AppStore is a real screensaver, i.e., one

 I suppose, I would need to write a little application, the only purpose of 
 which is to copy the screensaver bundle to ~/Library/Screen Savers/.
 Is that correct?

Yes.

Is that the easiest way?

No. The easiest way would be to install the screen saver from the
installation package. But Xcode does not allow this.

 Do you think, Apple might allow such an app into the AppStore?

No, because unless your company name is Apple, Inc, you are not
allowed to distribute what is basically an installer on the Mac App
Store.

So your best course of action is either to wait and see whether Apple
does something to allow screen savers (or Preferences Panes) in the
future on the Mac App Store or you could just start saving money to
perform a hostile takeover of Apple and make the changes you would
need to the Mac App Store policy.

 If so, what would be the easiest way to write such a copy-cat app?

 Also, I am a bit concerned about sandboxing.

As is probably everyone.

 Could that be a problem? (once it's enforced)

No, as most screen savers are good candidates for sandboxing
(exceptions would include the slideshow screen savers).

 (Particularly on iOS, which exposes a lot fewer system-level APIs than Mac

 Ignore the documentation; it's a bug. Use initWithFrame:

 initWithFrame: used to be explicitly listed in the QTMovieView header, and my

Re: How to detect Time Machine volume?

[Stephane Sudre]

This code would work in most cases but is actually unreliable.

Obvious cases: you have 2 text files with these names ar the root of a
partition.
Worse case: an old time machine partition has been replaced by a new
one. Since the old partition is some kind of a second backup, the user
has not removed the Time Machine files.

For Boot Camp, I tend to believe it's possible to get the information
using the statfs API.

For Time Machine, maybe it's safe to get the info from the
/Library/Preferences/com.apple.TimeMachine.plist file (assuming it's
there).

 NSFileManager *fm = [NSFileManager defaultManager];

        NSString *timemachine = [volumePath

 This works fine on my system. Will this code work reliably on my user's

 The same question can apply for iDisk and iCloud, probably.

 The reason I need to know is that I have a function using FSCatalogSearch 
 where I definitely don't want to access these type of volumes.

NSShowNonLocalizedStrings?

[Stephane Sudre]

Is the NSShowNonLocalizedStrings default values supposed to work as
described in the documentation?

If you set this default to YES (in the global domain or in the
application’s domain), then when the method can’t find a localized
string in the table, it logs a message to the console and capitalizes
key before returning it.

From what I've experienced, when this key is set to YES, almost all
the localized strings are displayed upper-case in the UI (even the
ones in nib files).

UTI for ScreenSaver, Automator Actions and PreferencePanes?

[Stephane Sudre]

Which UTIs are supposed to be used for CFBundleDocumentTypes 
LSItemContentTypes for :

- Screen Savers

- Automator Actions

- PreferencePanes

?

I want to be able to drag and drop them on an application icon.

I'm looking into getting rid of the CFBundleTypeExtensions array in my

[NSDate] Bug in dateByAddingTimeInterval: on Mac OS X 10.5

[Stephane Sudre]

According to the NSDate.h header:

- (id)dateByAddingTimeInterval:(NSTimeInterval)ti
AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER;

Problem is when I run the following code on Mac OS X 10.5 on a
PowerMac G5, I get the result listed below.

#import Foundation/Foundation.h

int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

NSLog(@dateByAddingTimeInterval: %@,[[NSDate date]
dateByAddingTimeInterval:24*60*60]);

NSLog(@addTimeInterval: %@,[[NSDate date] addTimeInterval:24*60*60]);
[pool drain];
return 0;
}


$ ./TestAPIDate
2010-11-22 16:59:15.900 TestAPIDate[4192:10b]
dateByAddingTimeInterval: 2020-10-13 09:58:31 +0200
2010-11-22 16:59:15.901 TestAPIDate[4192:10b] addTimeInterval:
2010-11-23 16:59:15 +0100

So it looks like this API is broken on Mac OS X 10.5 and should not be
said to be available for Mac OS X 10.5 in the 10.5 SDK Headers.

Am I missing something obvious? (I will file a bug report later if I'm
not missing anything).

 Checkboxes aren't edit controls, they are buttons, and to my knowledge don't 
 even have an editable property (even though the table column has such a 
 binding). To prevent changing a button state (without significant 
 subclassing) you must disable it. In this case, of course, we are talking 
 about NSCells.

IIRC, it does not require significant subclassing. Maybe 1 or 2 short methods.

Anyway, this is indeed only interesting in very uncommon cases as a
user will usually expect a checkbox to be clickable if it's enabled.

Re: Continuous animation locks UI?

Not sure if this is the same on iOS but in Mac OS X, you can call -

 Hi everyone,

 I'm working on an iPhone app, and I'm trying to make the title in the 
 navigation bar scroll.  I've got a UIView subclass that I wrote that, given a 
 string, will lay out some UILabels and then animate a frame change to give 
 the appearance of scrolling.  This works just fine.  I instantiate one of 
 these scrolling label objects and set it as the titleView property of my 
 viewController's navigationItem.  This also works fine, and the title scrolls 
 as expected.

 The problem is that the entire UI is totally unresponsive.  Nothing registers 
 user interaction.  My timers still fire, the UI can get updated 
 programmatically, but gestures, taps, swipes, etc are all totally ignored.  
 Even the UIBarButtonItems in the navigationItem are unresponsive.

 If I take out my scrolling text view, everything works fine (except I 
 obviously don't have a scrolling title).  As soon as I put it back in, the UI 
 goes dead.

 I'm doing the animations with the 4.0 UIView block-based animation API.  I 
 tried using an NSTimer to animate frame changing, but parts of my app 
 require dragging for user interaction.  The dragging would prevent the timer 
 from firing at consistent intervals, resulting in the scrolling slowing down 
 dramatically.  As far as I'm aware, the only reasonable way to animate a user 
 interface element without interfering with the main thread's run loop is with 
 CoreAnimation and layers (correct?).

 So:

 Why would my scrolling text view be killing my UI?  What can I do to get 
 around this?

 (For reference, the implementation of my ScrollingTextView is here: 
 http://pastie.org/1142995 , along with a relevant UIView category)

 Thanks,

[NSTextView] Is there a workaround for Snow Leopard new word selection behavior/bug?

[Stephane Sudre]

Case:
-

I need to detect double-click on a word when the alt key is hold down
(to do something similar to what Xcode does).

To do this I subclassed NSTextView and implemented a custom the
mouseDown: method (that calls the super method, don't panic).

This works fine on Mac OS X 10.4.x and 10.5.x.

Problem:


This does not work as well in Mac OS X 10.6.

Because when you double-click on the word myclass in a text like this:

myclass.mymethod

this selects myclass.mymethod.

On previous OS versions, only myclass was selected.

Question:
-

Is there a way to revert to the previous/right behavior?

I looked in the documentation which is full of set/is methods but not
the one I'm looking for as far as I can tell.

 You can add a delegate to your NSTextView that will intercept the proposed 
 selection and shrink it. That's what I do with my custom SQL text view: it 
 extends selections ending in the middle of a keyword to its end. What you try 
 to do is somehow the contrary, but it should not be much more difficult.

 Check: -(NSRange)textView: willChangeSelectionFromCharacterRange:

[NSOutlineView/NSTableView] Returning nil enables auto-edition?

[Stephane Sudre]

Mac OS X 10.4.11 (PPC)

I'm seeing a potential bug or unsupported behavior when it comes to  
cell edition.


I have a NSOutlineView. One of the column data cell of this view is a  
text field cell which is potentially editable.


Now, if I return nil in

- (id) outlineView:(NSOutlineView *) inOutlineView  
objectValueForTableColumn:(NSTableColumn *) inTableColumn byItem:(id)  
inItem


and then later set the string value (through setStringValue:) in

- (void) outlineView:(NSOutlineView *) inOutlineView willDisplayCell: 
(NSCell *)cell forTableColumn:(NSTableColumn *) inTableColumn item: 
(id) inItem


there's a very weird behavior with leaf rows:

When I select them (first click, it's not like the default behavior  
in 10.5), the text field cell automatically enters edition mode  
without even asking the opinion of


- (BOOL) outlineView:(NSOutlineView *) inOutlineView  
shouldEditTableColumn:(NSTableColumn *) inTableColumn item:(id)inItem



Is it a bug or just an unsupported scenario?

have been addressed through software updates -- not surprising given 
the rather sweeping and intrusive set of changes needed to support GC.

An issue is that the previous releases still exist (retail Mac OS X 
Leopard boxes are still 10.5?) and that someone may need to support 
them. And in these cases, I would consider that retain/release is more 
reliable.


I have a stupid question too. Considering that I sometimes see warnings

Let me re-emphasize one point:  I'm referring to new development.   
Given the APIs and technologies in Leopard, its maturity within the 
marketplace, the sales rate of Macs, the typical multi-month app 
development cycle, and the extremely high upgrade rate for previous 
owners,  targeting new development to Leopard only makes a lot of 
sense.


Targeting Leopard makes sense. I was just referring to Leopard 10.5, 
10.5.1 and 10.5.2 assuming the bugs had been fixed in 10.5.3.

And also how do they make this Bar at the Bottom?



The only real answer to that is Use FScript to find out. 
http://www.fscript.org. You'll need to download a separate version of 
FScript Anywhere for Leopard. Apple is usually not eating it's own 
dog food, Apple apps notoriously use their own UI implementation.


If you are interested how _you_ can achieve something similar, there 
is a chance to build a view containing some NSButtons with gradient 
look and either add manually the pulldown functionality to them or use 
an NSPopupButton and tinker with the menu contents so it always shows 
the icon and not the selected item.


The NSActionTemplate and NSAddTemplate should also be handy. Many 
goodies (gradient look, system provided images) are Leopard only.


Well, with only Interface Builder and the Finder (Mac OS X 10.4.11), 
you can find that it's custom views/controls with custom pictures (no 
gradient code AFAIK).

vertical scrollbars on the leftmost tableview and synchronize the 
scrolling and selection (both key and scroller) in both tableviews.

(void)awakeFromNib but I can't seem to make it do what I want it to 
do. Is there any other way I can do this?

If I were you, I'd do something like (warning: Mail compiled code):
const char* MyGetLocalizedCString(CFStringRef string)
{
   // if you need to be thread safe, add proper locks around that
   static CFMutableDictionaryRef mapping = NULL;
   if(mapping == NULL) {
   mapping = CFDictionaryCreateMutable(NULL, 0,
kCFTypeDictionaryKeyCallBacks, NULL);
   }

   const char* result = (const char *)CFDictionaryGetValue(mapping,
string);
   if(result == NULL) {
CFStringRef localizedString =  
CFCopyLocalizedStringFromTable(string,

CFSTR(LibraryLocalizable), NULL);
result = (const char
*)malloc(CFStringGetMaximumSizeForEncoding(CFStringGetLength(localize 
dString),

kCFStringEncodingUTF8);
CFStringGetCString(localizedString, (char *)result, bufferSize,
kCFStringEncodingUTF8);
CFDictionarySetValue(mapping, string, result);


I'm not sure CFDictionarySetValue would accept a char *.


It accepts whatever you want. You just have to set the corresponding  
callback when you create it. As you can see here, this sample use NULL  
as Value CallBack, so it perfectly valid to set a char *.


You're right. It just seems strange from a memory management point of  
view.
