valueForKeyPath: not found in protocol
Hi,
I've somewhat the same problem as a recent thread, but I can't fix it with what
was suggested in that thread.
I've to following class:
#import Foundation/Foundation.h
#import AudionetCommand.h
#import AudionetQueueDelegateProtocol.h
@interface AudionetCommandQueue : NSObject {
id AudionetQueueDelegate delegate;
}
@property (nonatomic, assign) id AudionetQueueDelegate delegate;
- (void) enqueueCommand:(AudionetCommand *)command;
@end
@implementation AudionetCommandQueue
@synthesize delegate;
- (void) enqueueCommand:(AudionetCommand *)command {
//Lots of code
if ([[delegate valueForKeyPath:@audionetDevices.address] isEqual: []]) {};
}
@end
I get the warning that valueForKeyPath: is not found in the protocols. If I
change the instance variable to id AudionetQueueDelegate,NSKeyValueCoding, I
get the error that the NSKeyValueCoding protocol can not be found. If I also
#import NSKeyValueCodingProtocol.h than that header file is not found.
How can I fix this?
Kind regards,
Remco Poelstra

Re: valueForKeyPath: not found in protocol
AFAIK, when something is referenced as a protocol like that, the *only* methods
it knows about are the ones in the protocol. If you just cast the delegate to
type id, you should be OK (I have encountered similar situations where this
solution worked)

That works indeed. I hoped there was a more elegant solution.

Re: valueForKeyPath: not found in protocol
Or use
NSObject* protocol
Instead of id. Assuming that all the objects are NSObjects.

Re: valueForKeyPath: not found in protocol
Your AudionetQueueDelegate protocol is probably not inheriting from
NSObject (the protocol) so it warns that valueForKeyPath: is not
found. It'll also probably complain about methods like
respondsToSelector: which is also part of the NSObject protocol.
You need to write your protocol declaration in
AudionetQueueDelegateProtocol.h as:
@protocol AudionetQueueDelegate NSObject
...
@end
Then it should silence the warnings and no casting is required (which
is not the correct solution in this case I believe).

(there's a built in Visual Basic function called Get text selection position relatively to page, but that there is no way to determine that page's location) Would that be possible to achive using cocoa framework's means?

Re: Get current caret position
Hi George, What you want to do would is within another's application. Any public hooks/APIs could be used... In this case VB and AppleScript. For deeper, Cocoa-based integration, you would probably need to work with Microsoft. Couldn't hurt to try contacting them... The means mentioned earlier are from within your own application. You might also look into building an app/tool as a Service... Hi John Thanks for the answer The problem is that AppleScript allows to discover the caret's position only relatively to the page's left-top corner, while there is no way to determine that page's left-top corner absolute position. Thus, i can't place my popup window where the caret is located. I am pretty sure, Visual Basic doesn't give much more possibilities (AFAIK, VB and AS operate on the same core API, which is closed to public). And about For deeper, Cocoa-based integration, you would probably need to work with Microsoft. What do you mean by working with Microsoft? I am not sure, but as far as i know, they don't give out this low level API to 3d party developers? And how could i contact them? Perhaps some of Microsoft Office developers are looking through this mailing list. Is there a place where i could find information about who and on what conditions could get that mac:Office Word SDK APIs? You might also look into building an app/tool as a Service... but what advantages does building as service has comparing to an ordinary external Cocoa application?

Mac OS X does not let you do that. The closest you can get is through the Accessibility framework: apps expose an object hierarchy to the accessibility system that other apps can use to manipulate the user interface. However, this is optional both from the app developer's point of view as well as that of the user (the user needs to turn on access for assistive devices). IIRC, Word 2011 re-instated VBA support.

Re: Garbage Collection, Standard Out, NSTask
The issue [I'd bet -- don't have time to dive deep] is that you don't have a strong reference to the Tasker instance. Since notification observers don't hold strong references to observers, either, the garbage collector sees Tasker as garbage and collects it. You could fix this any number of ways; - keep a reference to the Tasker instance as an iVar - keep a global set around of active taskers and have 'em remove themselves when they are done - use CFRetain or the NSGarbageCollector API to tell the collector not to collect the tasker before done. b.bum ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Garbage Collection, Standard Out, NSTask
On Nov 16, 2010, at 09:17, Jon Gilkison wrote: Below is a simple test application that launches a process and logs the output as it runs. It works as expected when the app is set to no garbage collection, but as soon as I turn on garbage collection, the following notifications stop working: - NSTaskDidTerminateNotification - NSFileHandleReadCompletionNotification You can figure this out by working backwards. With GC enabled, the default notification center maintains only a weak reference to observers registered to it. So, if you're not getting notifications then it's likely the observer has been garbage collected too soon. Since the notification center isn't responsible for maintaining a strong reference to your observer object, what is? Well, nothing. You allocate the object in the app delegate, but you don't stash the result anywhere. That means your object is subject to garbage collection at *any* time after its creation. When that happens depends on when the GC thread actually runs. Likely the problem is somewhat masked in this case, because you're starting a non-Cocoa process, which is going to keep executing until either it finishes normally, or it crashes because a resource you allocated for it disappears after garbage collection. If you haven't seen a crash yet you've possibly just been lucky. Note that your code was always wrong because you were leaking the observer object. It just didn't matter until GC fixed the leak for you. So the short answer is probably that your application delegate should keep a strong reference to your observer object until the external task ends. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hello all,
I'm new to the list and somewhat new to OSX (not iphone!) development. I
spent ten years most of my time in java so it was a hurdle..
I am currently developing an app (APP-A) which does PDF manipulation. I have
a second app (APP-B), that provides a PDF Viewer which is older.
APP-A depends on APP-B as it uses APP-B for viewing manipulated PDFs. APP-B
is independent from APP-A.
I could put both apps into Applications. But if a User don't know what APP-B
is for as he might only wan't APP-A but didn't see the dependency, he might
delete APP-B and APP-A cannot work properly anymore.
To solve this I put APP-B into the resources of APP-A, and it works to launch
the app from this directory. I have not found any documentation from apple or
mailing-lists if this is unwanted, problematic or somewhat evil!? The launchd
finds the 'hidden' APP-B and behaves as expected...
Is this allowed and recommendable, or how could I solve this alternatively
and I don't want to merge the apps!?
The code signing in-depth technote (TN2206) advises against using Resources
for this. It suggests putting the helper app bundles in the Contents folder,
and single-file helper binaries directly inside Contents/MacOS.

Sorry, I forgot 'reply-all'
Yeah that was the source I was looking for. I've inserted a copy build phase. I
managed to put APP-B everywhere but not directly under Contents. I do it now by
a shellscript that I run after building. But this could'nt be the final
solution...
I put together some code, but it crashes. As I couldn't simply attach the
debugger (as the bash needs to copy it in the right position..) debugging is
complicated...
CFURLRef appURL;
CFBundleRef bundle = CFBundleGetMainBundle();
NSString *app = @B.app;
appURL = CFBundleCopyAuxiliaryExecutableURL(bundle,(CFStringRef)app);

The accessors defined on your NSManagedObject subclasses will not be called - unless you've added property accessors to NSManagedObject via a category (and you REALLY don't want to do that) that call them directly. the accessors will perform better than valueForKey/setValue:forKey: (see Dynamically-Generated Accessor Methods) Well, since migration only happens once in a lifetime of a database, I'm not too worried about it, unless it falls to zero, which is what happens when a method does not respond to selector exception is raised :( What you seem to be describing shouldn't be possible (unless you've added property accessors to NSManagedObject via a category) - the accessors defined on your subclass are not going to be called during migration because the instances being migrated are not instances of your class. - adam ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Core Data: During Migration, should use Primitive Accessors only?
On 2010 Nov 16, Adam Swift wrote: What you seem to be describing shouldn't be possible (unless you've added property accessors to NSManagedObject via a category) I definitely have not done that. I subclass NSManagedObject. Let's step back a little here: You should be able to use the standard KVC accessors during migration, NSManagedObjects will respond to the foo/setFoo: laccessors for properties defined in your managed object model. Well, -foo and -setFoo: won't even compile unless I change the type of the sourceInstance: parameter of the method to be a MyManagedObject* like this: - (BOOL)createDestinationInstancesForSourceInstance:(MyManagedObject*)foo entityMapping:(NSEntityMapping*)inMapping manager:(NSMigrationManager*)inManager error:(NSError**)error_p or else do some equivalent typecasting in the implementation. - the accessors defined on your subclass are not going to be called during migration because the instances being migrated are not instances of your class. Makes sense, but I distinctly remember debugging this and seeing in the call stack that KVO was calling my custom accessors. I'll have a closer look the next time that I run into this problem. Making a demo project of a Core Data migration is quite tedious. By the way, my custom accessors are also called if I used -valueForKey: and -setValue:forKey:. This is per documentation [1]: The access pattern key-value coding uses for managed objects is largely the same as that used for subclasses of NSObject—seevalueForKey: and drilling down, [2]: Default Search Pattern for valueForKey: When the default implementation of valueForKey: is invoked on a receiver, the following search pattern is used: • Searches the class of the receiver for an accessor method whose name matches the pattern -getKey, -key, or -isKey, in that order.

I think you're mixing up two different things here. 1. Regardless of whether we're talking about migrating or just using Core Data stores, *any* NSManagedObject, including vanilla ones whose entity doesn't name a custom subclass, has accessor methods for all of the properties in the corresponding entity definition. But the compiler doesn't know that these accessors exist, so you can't use them in source unless you arrange for @dynamic declarations of them, for which there are a couple of semi-automatic procedures. I guess to make such declarations usable, you could just *declare* subclasses and use subclass-typed pointers in the source code, even though the class is still officially NSManagedObject. I guess this oddity doesn't normally come up in non-migration scenarios, because if you want to make the dynamic accessors visible to the compiler, you'd likely specify a subclass in the entity, even if you don't actually override any accessors. 2. If you have a *custom* NSManagedObject subclass (i.e. whose subclass name is known to the Core Data entity), you can of course override the Core-Data-supplied accessor methods by writing your own. Adam was saying that there isn't supposed to be any legal way to use such custom subclasses during migration. All you've got are objects of class NSManagedObject, which notwithstanding their class have the dynamic Core-Data-supplied accessors. I guess this kind of blurs the boundaries of what a class is, since different instances have different APIs, but that's actually nothing new -- you could always extend the class API on a per-object basis via things like 'valueForUndefinedKey:'. TBH, I never thought all this through explicitly before, but this is how I think it works, unless my brain has gone into meltdown again. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

What is Mac's custom for an agent to display its GUI?

Re: What is Mac's custom for an agent to display its GUI?
I fumble-fingered the first message and sent it without actually typing anything. Sorry for the noise if the moderator didn't catch it. Someone may know an approved Apple method, but here are some things that are out there now you could emulate. You could have it in Applications and use a menu item to access its control panel (like Shimo, Jolt, Caffeine, BravoTunes). You could install your background app as a command-line app and have a GUI app in Applications that launches the control panel (see ClamXav for an example). You could put it in Library/Application Support and have access to the Control panel through System Preferences (like Roxio's Retrospect).

There are too many apps with Status Items these days. It's getting to be like Windows' system tray junk.

If your primary users mostly have 27 inch displays or bigger, add as much as you like. Seriously consider including a check on the size of display during status item activation and informing the user that this will take up significant space on small displays.

If you do not actually display any information in the Status Item, or not constantly need to display (like battery level), then you should consider just building a Preference Pane for System Preferences and a Dashboard widget for status and/or launch and/or control.

Re: NSSavePanel panel:shouldShowFilename:

Intercept network traffic on specific port
Hi I'm trying to achieve a kind of proxy/filter effect for a specific TCP/IP port. I want my application to act as a server to all other applications on the system for that specific port. For example, Safari connects to site www.whatever.com on port 412. My application is intercepting on port 412, so instead of getting a response from www.whatever.com, my application would serve as the server (and possibly open a separate connection from itself to that site). The type of behavior I'm after is similar to what PGP Desktop does with encrypting/decrypting e-mail. I'm looking for a suggestion on a framework/API I could use to do something like this. I'm not too sure whether there's something in the Cocoa frameworks that could do this, or whether I should be looking at something in BSD sockets. Any suggestions would be appreciated.

Is www.whatever.com someone else's site? If so, you'll need to run an HTTP proxy and configure Safari to use it to connect to the web. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Detecting shared folders
On Nov 15, 2010, at 4:01 AM, Leo wrote: I wonder if it's possible to detect a shared folder? That is a folder that is shared via File Sharing. It would seem to be possible, since the Finder puts a banner in the window for shared folders. Am I missing something obvious? Not obvious, no. I couldn't find an appropriate folder attribute in either Cocoa or AppleScript. Or any other way to distinguish a shared folder from other folders. There are some flags in Carbon File Manager structures about file system items that are supposed to indicate the shared status, but they don't seem to be supported any longer. I used Apple's FSMegaInfo to dump the info, as in: /path/to/FSMegaInfo -vvv FSGetCatalogInfo -kFSCatInfoGettableInfo path I also assume there must be a list of all shared folders in one of the Unix special directories. Or a way to retrieve it with a shell command. I did some extensive research, couldn't find anything. I doubt there's one single list. It depends on the specific sharing protocol and the configuration of the server for that protocol. I found that /etc/smb.conf includes /var/db/samba/smb.shares, and that file lists the shares in a manner which matches the settings in the Sharing preference pane. However, that would probably not apply if you don't share via SMB and only share via AFP. Hmm. I went hunting for the AFP configuration and think I did find the master list. Try this command: dscl /Local/Default -list SharePoints Then, take one of the listed share points and do these on it: dscl /Local/Default -read SharePoints/share point name dscl /Local/Default -read SharePoints/share point name directory_path Be sure to quote the share point name if it contains spaces or other characters that the shell will interpret. Since the dscl command is just a front-end to Directory Services, there should be a way to do this directly via those APIs. Some experimentation shows that these records are not modified as you enable and disable file sharing protocols or even all of file sharing. So, you'd have to test if file sharing is even enabled before paying attention to them. I believe that toggling file sharing servers on or off amounts to enabling and disabling the corresponding service in launchd. So, I think you may be able to query their status with SMJobCopyDictionary() and the relevant identifier (e.g. com.apple.AppleFileServer or org.samba.smbd).

Re: Maths package for 128/256 bit integers?
You may check Accelerate.framework.

Re: What is Mac's custom for an agent to display its GUI?

I have to write an application, that should run on the background. When the user needs, it should display some control panel. On Windows system i would have used System tray, and an icon there - when the user clicks on that icon, it displays some GUI. but what is the Mac's usual practice? I am thinking that the analog to that tray application is an agent, launched by launchd. On what event it is considered to be good to trigger that control panel? It depends on what you're writing. Don't use the status area (near the clock) just to provide access to your app. If you're writing a VPN client or something else whose status needs to be monitored continuously, the status area is a good place to put your UI: a status item with a menu that afford access to the app's configuration/preferences dialog. But don't use the status area for transient things. If you're writing a backup app, for example, and don't feel like burdening your users' status area with mundane backups are happening information, don't all of a sudden put UI to alert the user that something's gone wrong. But then how do you alert the user or let them configure things? If you have no configuration options (the only interaction you need in your background app is to alert the user) you can use the CFNotification API. If you *do* have configuration, then create an app that only configures things, and embed your background app as a helper tool inside this app wrapper. When you need to show UI, have your background app launch the main app that it's a part of. Alternatively, your main app could be a system preferences pane rather than a full-blown app. --Kyle Sluder You can also consider the option Apple chosen with Spaces, Dashboard, and Expose. Deploy a real application bundle that launch this panel when double clic it. -- Jean-Daniel ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
