Re: Best class for pixel-level image processing?
I am writing an application that wants to perform some basic computer vision computation, and I want a class that offers pixel-level access to an image. What would be the best way to approach this? Do something like: MyImageRep = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:pixelsWide pixelsHigh:pixelsHigh bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSDeviceRGBColorSpace bitmapFormat:NSAlphaFirstBitmapFormat bytesPerRow:pixelsWide * 4 bitsPerPixel:32]; And later: [NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithBitmapImageRep:myImageRep]]; and: [myImageRep representationUsingType:NSJPEGFileType properties:imageProps]; This should get you started.

Re: get the list of controls in a NSView
and as I believe I mentioned before, you can assign a numeric 'tag' to each view and control in interface builder and you can use the viewWithTag: method of UIView to search for a specific view with a specific tag. That's not a way of coding I think people usually use, you have to manage your own tag mapping (unfortunately you can't use a #define type value to tag views) and there are usually better ways to do this. However if assigning a tag in Interface Builder is an accessible operation where you've found making connections not to be, this may be a good way to find the objects you set up in IB and add the connections to them in your code.

Validating unique objects in CoreData
Hello, I would use CoreData in order to mantain an archive of objects: each object contains an attribute called uuid; in the same db only one object can have the same attribute value. This mean I should validate the proposed new object to insert and check if the another object with the same uuid is inside the storage. I've implemented it with a fetch request but it's so slow when there are lots of objects to insert (my db contains around 30,000 objects). Any idea to improve performance of this check? Can CoreData support unique attributes as like key in sql database?

Re: Best class for pixel-level image processing?
First: None of the Mac OS X image APIs are set up around completely bare access to pixels. Bare pixel access is at odds with performance. Take caching: In order to cache effectively, the frameworks needs to understand what's changing when, and that cannot happen when people have unmediated pixel access. It would effectively mean no caching. That said, CoreImage _is_ set up around access to pixels, just in a more structured way. You define kernels of processing to be applied, and CoreImage handles applying them. It also composes kernel chains beforehand, applying a composite kernel to an image in one pass when possible. There are lots of predefined image filters that you can chain together to do useful things. There are certain things that you cannot do this way (a histogram, for example), but it's a nice place to start if it sounds like what you need to do. The Quartz Composer app is a nice way to play with CoreImage stuff live. You could also consider OpenCL. This is somewhat similar, but more data oriented and less image oriented, and more flexible. Both CoreImage and OpenCL can use the GPU. Last, you could work in bare memory buffers, do whatever you want to them (but with no particular help from the system), and package up a copy of your buffer as an image when you want to draw it. For this packaging, look at NSBitmapImageRep or CGImage. This is kind of a brute force approach, but it uses the fewest special concepts, and that's attractive. You should realize that the system is not prepared for the bits to mutate behind the back of the framework when doing this. CGImage is immutable. NSBitmapImageRep is implemented using CGImage. These classes are oriented around fast drawing, not modification. -Ken Cocoa Frameworks On Wed, Feb 10, 2010 at 9:11 PM, Alexander Golec alexgolecmailingli...@gmail.com wrote: I am writing an application that wants to perform some basic computer vision computation, and I want a class that offers pixel-level access to an image.

Re: get the list of controls in a NSView
I don't understand what you mean by 'how to fetch each control into an NSView array'. You can get the subviews of the main view and keep going down finding all views that way recursively calling subviews on each, but it won't really help you as some of the controls make a collection of views up when you instantiate them so you are going to find more than just the top-level views of the controls you instantiated in IB. You really just want to get the objects which you dragged into interface builder. eg you put two buttons and a textfield on a view, you want the two buttons and the textfield. That's why I suggested viewWithTag: method, if you give the text view tag number 1 and the two buttons tags 2 and 3, you can easily find them by calling viewWithTag: with each tag from 1 to 3. No you can't use the name field in IB, that's why I suggested tags, the only piece of information which carries over from IB when your nib is instantiated is the value of the tag field, everything else is just interface builder internal stuff and you can't query it when the nib has been loaded. tags are generally a bit ugly because you have to, as I said, keep your own mapping that tag '2' means button1 but they do work and there is that function to query for them given a top-level view. So if you are unable to hook individual controls up to outlets and actions in IB, this is about the only reasonable way to do it. It's not that hard really, after the nib loads you just iterate through however many tags you have and when you find the view you use a switch statement to set it to the correct instance variable in your code and then hook up the actions. That said, doing this you really aren't gaining much over just instantiating the objects in code in the first place but I know you want to lay things out in IB, so this method will probably work.

Re: Validating unique objects in CoreData
two questions, neither of which actually answers yours I think. 1) does this uuid need to be something you generate externally and then set onto the object? Each core data object already has an objectID which is guaranteed unique in the database, can you make use of that one instead? You are allowed to keep that and use it to find objects later. 2) Where does the uuid on the object you are inserting come from? If you are setting a UUID on the objects when you are creating them then using one of the uuid_generate functions the UUID generated can be 'reasonably considered unique amongst all UUIDs created on the local system, and among UUIDs created on other systems in the past and in the future' (from the manpage). If you generate them in such a way, you don't have to care about checking them to be unique, they already will be.

Re: Guidance on use of Application Support folder
I sorta would agree, Jens, and certainly many apps do put user-specific files here, but the Apple docs specifically say this is NOT how the Application Support folder should be used. ~~~ A support file is any type of file that supports the application but is not required for the application to run. Document templates and sample files are simple examples of support files. However, you might store more application-bound information, such as custom configurations or preset data files for your application’s workspace. In these instances, the information is intrinsically tied to a specific application (as opposed to the user’s data) but is not essential for the application to run. http://developer.apple.com/documentation/MacOSX/Conceptual/BPFileSystem/Articles/WhereToPutFiles.html ~~~ In the File System Overview, is this: Table 1 Subdirectories of the Library directory Subdirectory Directory contents Application Support Contains application-specific data and support files such as third-party plug-ins, helper applications, templates, and extra resources that are used by the application but not required for it to operate. This directory should never contain any kind of user data. By convention, all of these items should be put in a subdirectory named after the application. For example, third-party resources for the application MyApp would go in Application Support/MyApp/. Note that required resources should go inside the application bundle itself. http://developer.apple.com/mac/library/documentation/MacOSX/Conceptual/BPFileSystem/Articles/LibraryDirectory.html#//apple_ref/doc/uid/20002282-BAJHCHJI Note the line: This directory should never contain any kind of user data. ~~~ There is some discussion of relevance here: http://www.cocoadev.com/index.pl?ApplicationSupportFolder On Feb 12, 2010, at 11:13 AM, Jens Alfke wrote: On Feb 12, 2010, at 8:05 AM, Stuart Malin wrote: I am building an app that needs to store per-user data that is not document specific.

Re: Guidance on use of Application Support folder
What has confused me about this is why does CoreDate store it's data in the Application Support folder be default then? On Feb 12, 2010, at 9:27 AM, Stuart Malin wrote: I sorta would agree, Jens, and certainly many apps do put user-specific files here, but the Apple docs specifically say this is NOT how the Application Support folder should be used. ~~~ A support file is any type of file that supports the application but is not required for the application to run. Document templates and sample files are simple examples of support files. However, you might store more application-bound information, such as custom configurations or preset data files for your application’s workspace.

This directory should never contain any kind of user data. By convention, all of these items should be put in a subdirectory named after the application. For example, third-party resources for the application MyApp would go in Application Support/MyApp/.

Re: Guidance on use of Application Support folder
Licenses belong in /Library/Application Support (no squiggle),
IMO. Plugins too, probably. But templates, yes, although
perhaps they might be stored in /Library/Application Support at
the user's option ('make this template available to all users of
this Macintosh').
Depending on what you want to do, take care when running user a

What sort of data is it, anyway?

It seems to me that it is telling you not to save user documents
there. Templates, user-installed plugins, licenses, and all
sorts of
other stuff goes (and belongs) in Application Support. The app
binary,
its required frameworks, its resources, etc. do not.

The beauty of the domained folder system is that we can put license
files in /Library/Application Support, ~/Library/Application Support,
or /Network/Library/Application Support. That was a great boon when I
was on the customer side of this equation, and had bundle licenses for
some products but an individual license for myself. Each machine (we

/Library/Application Support, but I carried my own licenses in my
network-mounted ~/Library/Application Support.

Re: Validating unique objects in CoreData
I've tried to make an alternative method. I'll try to describe it. I would to use a second an auxiliary index where to save my uuid-objectURI; results are better, so I try to make a summary of the problem and the solution. If anyone have a better idea I'll be happy to talk about it :) I've about 30,000 messages taken from network and I need to save all into a Core Data Store in form of a tree. Each message contains an unique identification string and no more than one message can be saved on database with the same id. CoreData at this time does not support uniqueness of attributes and I can't use objectID property to ensure this kind of thing. A first solution is, in pseudo code: - Execute a query to see if uuid string is presents in storage - If it's not present I can make a new NSManagedObject with that uuid and put it into storage, otherwise I'll ignore it (it's already on db) - Execute another query to find the direct parent of this new message, if found I'll link both messages, if not it's a root message This solution has a big problem. With 30k messages I need of 30k query to check if the new message exist on coredata, another 30k to check for parent (plus, I think, another 30k to insert the new object). Over 60k+ queries takes lots of time (a minute or more here). My second solution is to create a second auxiliary NSMutableDictionary where i'll save message uuid as key and NSManagedObjectID's URI rapresentation (the only I can save to NSData) as value for dictionary entry. The result in pseudo code is: - Use objectForKey:uuid to my auxiliary dictionary to see if the message exist in coredata - If yes I'll ignore it. If not i'll put it into the store - Use objectForKey:parentuuid to my auxiliary dictionary to see if the parent of the message is present on coredata. If yes i'll use NSPersistentCoordinator's managedObjectIDForURIRepresentation: to get the NSManagedObject (the parent of the message) and link both parent and child With this solution the entire process takes about 5 seconds to finish (the result dictionary it's around 2mb).___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Guidance on use of Application Support folder
Elaborate on the bugs? Well, we're getting a bit off topic for this list but
it's mainly to do with relocation which we want to disable because it does
things like update a copy of the application that has been dragged to the Trash
and other such nonsense. PM also throws a wobbly (with no useful error
message) if things like the postinstall script have the uchg flag set. That
probably won't bother most people but I like to write-protect my release tree
after making the final (we hope!) build in case of finger trouble.
The way I deal with the relocation issue, apart from turning it off in Package
Maker itself (which you have to do every time you save your package definition
because PM keeps turning it back on when you're not looking) is to run the
following inscrutable 3 lines of shell script after building your package
(where $mpkg is the folder containing the built package):
awk '/IFPkgPathMappings/ { sub (IFPkgPathMappings, xIFPkgPathMappings, $0);
print $0; next } // { print $0 }'
$mpkg/Contents/Packages/vinylstudio.pkg/Contents/Info.plist /tmp/no_reloc
mv /tmp/no_reloc $mpkg/Contents/Packages/vinylstudio.pkg/Contents/Info.plist
rm
$mpkg/Contents/Packages/vinylstudio.pkg/Contents/Resources/TokenDefinitions.plist
The third line is only needed for Snow Leopard. Mr Google dug it up for me, I
forget where. Saved my life.
I also hand-edit the various xml files in the .pmdoc folder to remove any
absolute references and to delete, in fact, the BOM, with the exception of the
top-level folder(s) to be packaged up (PM normally records all the files below
that, for some strange reason, but it is evidently redundant information and it
made me nervous having stuff recorded in there that might be added to, or
removed, after PM had last seen it). This lets me carry my .pmdoc folder
essentially unchanged over from one version of the software to the next. I
don't let Package Maker near it after that (apart from building the package
from the command line). Things like the readme file are kept out-of--line so
that they can be edited in TextEdit.
In other words, I now have a carefully hand-crafted .pmdoc folder safely
checked into version control. When things like the version number change, I
just hand-edit the relevant file. I hope never to let PM change these files
again.
Finally, to get PM to build your package from the command line, you have to
specify the --id flag, otherwise it crashes, something like:
/Developer/Applications/Utilities/PackageMaker.app/Contents/MacOS/PackageMaker
--id uk.co.alpinesoft.vinylstudio-installer --doc VinylStudio-Installer.pmdoc
--out $mpkg
Like you, I nearly gave up, but, as of this moment, I think I have the beast
under control.

If I run the Simulator on the Mac supplying the internet connection to the router itself, it doesn't see the other apps running on the touches. Do I need the Mac app to be running on a laptop connected to the router too to get it to work, or is there a way to tweak the WiTap code to have it work? Ultimately I'll have to adapt the WiTap thing to work for my desktop OS X app. I just don't know if I am making this more complicated than it needs to be? Or is this the right path?

Connected Objects being allocated
Once again, I am not understanding some aspect of Objective C and/or Cocoa.
I created a simple class that contains two NSTextField objects. I used IB to
connect the Controller object with the two text fields. The code follows.
This example runs correctly and does copy the value from one text field to the
other.
#import Cocoa/Cocoa.h
@interface Controller : NSObject {
IBOutlet NSTextField* textField;
IBOutlet NSTextField* copyField;
}
- (IBAction) buttonTarget: (id) sender;
@end
#import Controller.h
@implementation Controller
- (IBAction) buttonTarget: (id) sender {
int textValue;
textValue = [textField intValue];
[copyField setIntegerValue:textValue];
}
@end
Now if I extend this to two objects (Controller and View), the resulting code
does not execute correctly. Again, I used IB to connect the View object to the
two text fields. Using the debugger I find that the two NSTextField objects
have not been allocated (both have nil values). The code follows:
#import Cocoa/Cocoa.h
#import View.h
@interface Controller : NSObject {
View* view;
}
- (IBAction) buttonTarget: (id) sender;
@end
#import Controller.h
#import View.h
@implementation Controller
- (id) init {
if (self = [super init]) {
view = [[View alloc] init];
}
return self;
}
- (IBAction) buttonTarget: (id) sender {
[view copyFieldValue];
}
@end
#import Cocoa/Cocoa.h
@interface View : NSObject {
IBOutlet NSTextField* textField;
IBOutlet NSTextField* copyField;
}
- (void) copyFieldValue;
@end
#import View.h
@implementation View
- (void) copyFieldValue {
[copyField setIntegerValue:[textField intValue]];
}
@end
I have no idea what I am doing wrong. Any help would be most appreciated.
Thanks in advance.

Re: Connected Objects being allocated
On Feb 12, 2010, at 1:31 PM, Donald Klett wrote:

Okay, all is groovy so far.What you've left unstated in the explanation
above is that the
two text fields must have been allocated *somewhere*.I can make a SWAG that
you
dragged a couple of text fields from IB's palette onto the (content view) of
the main window
that shows up when you open MainMenu.xib, yes ?
If that is the case, you have two (instantiated and correctly * initialised by
IB) text fields that
you can connect to from your (presumably also instantiated and initialised by
IB) Controller
object.
Now if I extend this to two objects (Controller and View), the resulting code
does not execute correctly. Again, I used IB to connect the View object to
the two text fields. Using the debugger I find that the two NSTextField
objects have not been allocated (both have nil values). The code follows:
#import Cocoa/Cocoa.h
#import View.h
Minor detail here.Use @class forward references in .h files instead
of importing the class's .h file in your Controller's .h file.In other
words,
delete the#import View.h line and add a @class View;line . . .
This tells the compiler you'll be referencing the View class in your .h file
with an unspoken promise you will include the View.h file in your
Controller's .m
file . . .
@interface Controller : NSObject {
View* view;
}
- (IBAction) buttonTarget: (id) sender;
@end
#import Controller.h
#import View.h
@implementation Controller
- (id) init {
if (self = [super init]) {
view = [[View alloc] init];
}
return self;
}
Below, you have View as a sub-class of NSObject.Why?
If View is supposed to be a sub-class of NSView, your [[View alloc] init]
above needs to be [[View alloc] initWithFrame: . . .]
- (IBAction) buttonTarget: (id) sender {
[view copyFieldValue];
}
@end
#import Cocoa/Cocoa.h
@interface View : NSObject {
IBOutlet NSTextField* textField;
IBOutlet NSTextField* copyField;
}
- (void) copyFieldValue;
@end
Based on this declaration, do you have a View object instantiated in your
MainMenu.xib,
and did you then connect the two outlets to the two text fields from that
already instantiated object?
If so, after then instantiating a View object in your Controller, your
Controller is now talking to
the wrong View object and the one from the xib is being ignored . . .
#import View.h
@implementation View
- (void) copyFieldValue {
[copyField setIntegerValue:[textField intValue]];
}
@end
I have no idea what I am doing wrong. Any help would be most appreciated.
Thanks in advance.
I hope this helps a little. One of the more common beginner mistakes
is to instantiate an object in the xib, and then instantiate a completely
new version in code . . .
And as (I think) someone already pointed out, if you have a class whose
name is View, anybody reading your code superficially would expect it to
*be* something that relates to existing NSView or UIView classes and have
View-like behaviour . . .
A useful exercise to do is to look at your xib objects and draw a picture of
the objects and their connections --- that essentially defines your 'Application
Architecture', and a picture can quickly show up anomalies in the object
graph --- either orphan objects as I suspect in the case, or objects that aren't
really doing anything useful . . .

Re: Connected Objects being allocated
Don,
Your first snippet of code is great and follows MVC just fine. However, your
second snippet breaks away from proper MVC, in the vein of over-thinking
your architecture.
When in doubt, start simple and extend as needed. In your first snippet,
your Controller class is a valid Controller in the MVC sense of things. Just
stick it in a NIB file, connect the outlets, and you're all groovy.
But here's some things to explicitly avoid:
(1) Name classes inappropriately. As mentioned before, View should not be
a subclass of NSObject without any view components. It should be a subclass
of NSView or something similar (NSControl, NSTableView, etc)
(2) We Cocoa coders don't usually instantiate views inside -init, but rather
inside a NIB file. Having NIBs loaded automatically for us via
NSViewController or NSWindowController is pretty standard and good practice.
(3) View classes shouldn't usually have Controller code in it. View classes
should be generic and reusable, whereas Controller is specific to a single
purpose inside an app (or multiple apps, if it's a shared framework).
(4) Try to use a prefix in your class names. I usually use SD, like SDView
or SDController or SDButton, for instance. This helps prevent namespace
collisions. Not entirely relevant to your question, just throwing it out
there.

Re: @distinctUnionOfArrays problem
I am trying to get @distinctUnionOfArrays to work with bindings. I have a Master NSArrayController. This contains an array of NSMutableDictionary objects.

I then have a single-column TableView Genre I have Genre NSArrayController and I try to bind this array controller to the Master Controler with IB: Genre, bound to Master Controller key: arrangedObjects Model Key Path: @distinctUnionofArrays.Genre As a follow-up, this works in code: NSArray* allObjects = [masterController valueForKeyPath:@arrangedObjects.Genre]; NSArray* uniqueObjects = [[NSSet setWithArray:content] allObjects]; I have 10 records, but only 4 types of Genres and I end up with 4 objects as expected in uniqueObjects. I just can't make it do the same thing with bindings. Ultimately, I am trying to build a filter ala iTunes for a large array of NSMutableDictionary. I want to get a list of unique Genres and Albums, then filter Albums based on the selection in Genres and filter the finalArray on the selection in Albums as well.

NSTokenField: binding + disappearing tokens
Hi there!
I am having a bizarre problem with NSTokenField. In Interface Builder, having
bound the field's value binding to an NSArrayController containing
NSManagedObjects, and passing the value through a ValueTransformer, the field's
tokens show up, displaying the proper values. However, when the mouse enters
and then leaves, the tokens disappear (unless the mouse leaves by the top of
the field). Weird, right? I can find no reason why this should be so.
Any thoughts would be vastly appreciated!
Peace,
andy shamel
Here are the configurations:
Relevant Core Data Entity info
Name: Character
Relationship: named seniorArtisan to-one, connected to Character
The NSArrayController is set to Entity mode, with the Character entity.
Prepares content, managedObjectContext bound to App Delegate
The NSTokenField is bound in Interface Builder with default options to the
above NSArrayController, Controller Key: selection, Model Key Path:
seniorArtisan, and Value Transformer: TokenRelationshipTransformer
Here's the TokenRelationshipTransformer's code:
+ (void)initialize
{
[TokenRelationshipTransformer
setValueTransformer:[[[TokenRelationshipTransformer alloc] init] autorelease]
forName:@TokenRelationshipTransformer];
}

Youtube video upload ussue
Hi All,
I have got a very frustrating problem. I am trying to upload video to youtube
using GData APIs and am having significant issues. I am sure one of you will
have done this previously and I hope you can assist me.
I have copied the cocoa sample and just put it in my code to get something
working I can customise it later. When this code executes it fails with the
following error
*** Assertion failure in -[GDataServiceBase
fetchObjectWithURL:objectClass:objectToPost:ETag:httpMethod:delegate:didFinishSelector:completionHandler:retryInvocationValue:ticket:](),
/Users/damien/damien/projects/google/gdata-objectivec-client-read-only/Source/BaseClasses/GDataServiceBase.m:559
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'GDataHTTPUploadFetcher needed'
Ok so I go to the source of the assertion failure
//
// now that we have all the request header info ready,
// create and set up the fetcher for this request
//
GDataHTTPFetcher* fetcher = nil;
if (isUploadingDataChunked) {
// hang on to the user's requested chunk size, and ensure it's not tiny
NSUInteger uploadChunkSize = [self serviceUploadChunkSize];
if (uploadChunkSize kMinimumUploadChunkSize) {
uploadChunkSize = kMinimumUploadChunkSize;
}
Class uploadClass = NSClassFromString(@GDataHTTPUploadFetcher);
GDATA_ASSERT(uploadClass != nil, @GDataHTTPUploadFetcher needed);
NSString *uploadMIMEType = [objectToPost uploadMIMEType];
fetcher = [uploadClass uploadFetcherWithRequest:request
uploadData:uploadData
uploadMIMEType:uploadMIMEType
chunkSize:uploadChunkSize];
} else {
fetcher = [GDataHTTPFetcher httpFetcherWithRequest:request];
}
So it appears the Class uploadClass =
NSClassFromString(@GDataHTTPUploadFetcher); line fails. This tells me that
there is no instance of the GDataHTTPUploadFetcher class at this time.
Ok so what did I miss in my method I can not find any definition of a
GDataHTTPUploadFetcher in the sample project.
I have provided my method below hoping someone can assist me by comparing mine
to theirs and showing me where I have gone wrong. I really appreciate your
assistance.

Re: get the list of controls in a NSView
Remember the original poster is blind. He can use interface builder to create and position widgets and it seems that the dialogs allowing you to set position and other attributes (like tag) are accessible but the control drag to hook objects up to outlets or set actions is not accessible, so he can't do it. He is as far as I can tell trying to find a way to locate the objects in interface builder he would have hooked up to outlets if he were able to do so, after the nib has loaded, and then do those hookups in code. I still think just building the interface in code is easier but he wishes to use Interface Builder for whatever piece of the process he can.

Re: @distinctUnionOfArrays problem
It sounds like you are using an NSTreeController as the master not an NSArrayController, so you'll want to do: valueForKeyPath:@childnod...@distinctunionofobjects.genre at least I think so. childNodes will give you an array for all the nodes in your tree. Ok - so I did manage to get it working... Going in the right direction. I have got my original table (4 columns) and I have two filtering columns that are the unique values from the Genre and Album columns of my master table. Album is still not filtered through Genre... I don't think there is a bindings way to build a predicate base on the selection in these two tables though. Ultimately I want to first filter the Albums column by building a predicate filter on the master database's Genre. Does anyone know of examples for this - noting seems to be on Apple's site.

warning when setting the delegate of SpeechSynthesizer
Hello everybody,
I'm having a difficult time trying to figure out why cocoa gives me a warning
when trying to implement a delegate method in my class.
I'm writing the SpeakLine application from Aaron Hillegass' book in which the
user enters a line of text and there's 2 buttons: Stop and Speak.
When the user presses Speak, the speak button should go not enabled and Stop go
enable, and when the SpeechSynthesizer finishes the opposite should happen.
Anyway, I set the delegate as self in the init method, like so:
-(id) init {
[super init];
speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil];
[speechSynth setDelegate:self];
return self;
}
and implement the method didFinishSpeaking like this:
-(void) speechSynthesizer:(NSSpeechSynthesizer *)sender
didFinishSpeaking:(BOOL)complete {
NSLog(@Complete = %d, complete);
[startButton setEnabled:YES];
[stopButton setEnabled:NO];
}
I get the warning: Class 'AppController' does not implement the
'SpeechSynthesizerDelegate' protocol at the line [speechSynth
setDelegate:self];
Is there anything obviously wrong with what I'm doing? I followed the book
exactly and still get this warning.
Thanks in advance.
Martin.

I get the warning: Class 'AppController' does not implement the
'SpeechSynthesizerDelegate' protocol at the line [speechSynth

Is there anything obviously wrong with what I'm doing? I followed the book
exactly and still get this warning.
Thanks in advance.

Re: warning when setting the delegate of SpeechSynthesizer
Aaron's book came out before Snow Leopard, back when @optional was not
available; thus any protocol which declared at least 1 optional method must
be an informal protocol. This is not so anymore ever since 10.6's SDK. Thus,
NSSpeechSynthesizerDelegate did not exist when the book was written.

Subject: warning when setting the delegate of SpeechSynthesizer
Hello everybody,
I'm having a difficult time trying to figure out why cocoa gives me a
warning when trying to implement a delegate method in my class.
I'm writing the SpeakLine application from Aaron Hillegass' book in which
the user enters a line of text and there's 2 buttons: Stop and Speak.
When the user presses Speak, the speak button should go not enabled and
Stop go enable, and when the SpeechSynthesizer finishes the opposite should
happen.
Anyway, I set the delegate as self in the init method, like so:
-(id) init {
[super init];
speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil];
[speechSynth setDelegate:self];
return self;
}
and implement the method didFinishSpeaking like this:
-(void) speechSynthesizer:(NSSpeechSynthesizer *)sender
didFinishSpeaking:(BOOL)complete {
NSLog(@Complete = %d, complete);
[startButton setEnabled:YES];
[stopButton setEnabled:NO];
}
I get the warning: Class 'AppController' does not implement the
'SpeechSynthesizerDelegate' protocol at the line [speechSynth
setDelegate:self];
Is there anything obviously wrong with what I'm doing? I followed the
book exactly and still get this warning.
Thanks in advance.
Martin.

Re: Replacing model objects using an NSArrayController
On Feb 11, 2010, at 10:33 PM, Quincey Morris wrote: There isn't a replace method for an array controller. If you must do it as a single operation, then solution would be to fetch the original object at the end of editing, update its properties to match the (edited) properties of the copy, then discard the now-temporary object copy. However, your description doesn't completely make sense. There are no objects in an array controller. Instead, think of the array controller as a sorted, filtered perspective on your underlying data. Normally, the array controller is monitoring the underlying data via KVO, so any underlying changes are noticed and it adjusts itself accordingly without your writing any code. You seem to be saying that you've already updated the underlying data model (I have implemented all of the KVC methods in the Manager class ...), in which case you *don't* want to mess with the array controller directly. Basically, there are two approaches to adding, deleting and replacing, when an array controller is involved: 1. Update the data model directly and KVO compliantly, and let the array controller notice the changes via KVO. 2. Do not update the data model directly, but use the array controller methods instead (removeObject:, insertObject:atArrangedObjectIndex:, etc). These methods internally cause the data model to be updated. Pick one. Not both. Method #1 is the cleanest, because it doesn't introduce the array controller (which is really part of your UI glue code) into the data model update, but you *must* ensure that the data model change is made KVO compliantly. Typically, that means making the changes using a mutableArrayValueForKey: proxy object. Method #2 is a convenience when you've not built (or have not been able to build) a clean MVC design into your app, or when you must work with the arrangedObjects order for some reason. Others will likely disagree with me, but I think that there's something a bit smelly about code referring to array controllers. It often indicates a defect in the MVC design. Quincey, Your explanation took a little while to make sense to me, but I finally did have the aha moment. You were right that I was confusing my MVC design, trying to use a controller object to tell another controller object to change the model. I wasn't aware that I could just change the model directly and that KVO would affect the other controller for me. It still seems rather magical how it does that, but I've reworked my code to directly call my replaceObjectInMyArrayAtIndex:withObject: and verified that the changes are now flowing through to the UI just how I wanted. Thank you for helping me through this learning experience; I'm sure I will draw from it again and again.

Re: Validating unique objects in CoreData
That's not a horrible solution, except for the feeling that core data ought to let you do what you want without having to implement your own UUID cache. I'm still a bit surprised that a lookup for an object by one attribute is taking so long, over just 30,000 objects. You do have the uuid attribute marked as indexed right? I found http://cocoawithlove.com/2008/03/testing-core-data-with-very-big.html whilst hunting around for some examples of core data with big data sets. This guy was working on sets of 1 million objects and doing fetches with indexed properties was taking about 2 seconds, vs non-indexed, 600 seconds. There are some comments at the bottom from an apple engineer too. On 13-Feb-2010, at 2:06 AM, malcom wrote: I've tried to make an alternative method. I'll try to describe it. I would to use a second an auxiliary index where to save my uuid-objectURI; results are better, so I try to make a summary of the problem and the solution. If anyone have a better idea I'll be happy to talk about it :) I've about 30,000 messages taken from network and I need to save all into a Core Data Store in form of a tree. Each message contains an unique identification string and no more than one message can be saved on database with the same id. CoreData at this time does not support uniqueness of attributes and I can't use objectID property to ensure this kind of thing. A first solution is, in pseudo code: - Execute a query to see if uuid string is presents in storage - If it's not present I can make a new NSManagedObject with that uuid and put it into storage, otherwise I'll ignore it (it's already on db) - Execute another query to find the direct parent of this new message, if found I'll link both messages, if not it's a root message This solution has a big problem. With 30k messages I need of 30k query to check if the new message exist on coredata, another 30k to check for parent (plus, I think, another 30k to insert the new object). Over 60k+ queries takes lots of time (a minute or more here). My second solution is to create a second auxiliary NSMutableDictionary where i'll save message uuid as key and NSManagedObjectID's URI rapresentation (the only I can save to NSData) as value for dictionary entry. The result in pseudo code is: - Use objectForKey:uuid to my auxiliary dictionary to see if the message exist in coredata - If yes I'll ignore it. If not i'll put it into the store - Use objectForKey:parentuuid to my auxiliary dictionary to see if the parent of the message is present on coredata. If yes i'll use NSPersistentCoordinator's managedObjectIDForURIRepresentation: to get the NSManagedObject (the parent of the message) and link both parent and child With this solution the entire process takes about 5 seconds to finish (the result dictionary it's around 2mb). ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

That's right, it's almost not in the documentation anywhere is it, I'd forgotten that. I only started with core data a few weeks ago and messed about with every checkbox I could to see what it did, and I looked for it at the time in the docs and found nothing. There is a mention of an 'isIndexed' property in the NSPropertyDescription class which says that a store can optionally use this information for creating indexes. I can confirm (from looking at the sqllite database) that core data using sqllite appears to create indexes for relationships and for properties marked 'indexed', with the usual caveat that looking at the tables core data makes is entirely unsupported and could change at any time. I can only assume that the queries it sends for fetches with simple properties are such that the sqllite engine can make use of those indexes. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

UINavigationController inside a TabBarController
I'm not sure what I'm missing but I know it must be big. I started the design of a TabBar-style app and now, I want one of the view to be a navigation one.

Your Navigation Controller must be one of the controllers in the Tab Bar Controller's array of View Controllers. Then, the Navigation Controller's Root View Controller must be the Table View Controller. Is that the structure you have? Possibly there is either a class identity that has not been correctly set, or, there might be a Nib Name that is not correctly set.This stuff is notoriously easy to get wrong . . . In IB's List View inspector, go through each of the Tab Bar's list of View Controllers.Make sure their Class identities are the correct type of View Controller, and make sure that their NIB names (if appropriate) are correct. In a simple experiment, I dragged a Tab Bar Controller into a XIB. I deleted one of the (two) View Controllers from the Tab Bar Controller. Then I dragged a Navigation Controller into the XIB, and moved it into the Tab Bar Controller's hierarchy.But the Navigation Controller's Root View Controller's class identity shows up as a simple UIViewController. I had to select that and specifically set its identity to UITableView Controller. Hope This Helps a Little . . . Cheers, . . . . . . . .Henry = iPhone App Development and Developer Education . . .

Re: UINavigationController inside a TabBarController
Thanks, that was helpful but I had already figured it out. After examining the Recipes sample, which does exactly what I wanted to do, I did notice that the sample didn't have a pre-configured tableview. So, I removed my tableview from the view hierarchy and, in viewDidLoad, I did set the tableview to the view pre-configured in IB. Works perfect! Now, if I could find how to get small UISegmentedControls, life would be good. You know, like in Settings-General, there is a small segmented control for the Location Services.
