iTunes-like tail truncation for attributed strings
Folks; I have a source list type view. I am using a tableView not an outlineView because it works for this data set. I have an attributed string which has an image and a name. This is the only column in this tableView. This tableView is contained in a splitView which allows this 'nav' to be re-sized A lot of words to describe something quite similar to iTunes. As you reduce iTunes playlist column size toward its minimum, the playlists do a 'tail truncation' on any long text. How do I achieve that? What I am seeing regardless of many different settings, is that the text 'breaks' at the space between the image and wraps to a a second line. I have Truncate Tail set in the Text Field Cell for the table column. Can you achieve this with effect with IB and an attributed string or is some other code solution necessary? Thanks for any help!

NSComparisonResult, 'double wildcard'
Hi all, I'm looking at the TableSearch example to implement a similar view with a UISearchBar which essentally should act as a filter for the cells in the UITableView below it. The TableSearch example implements an NSComparisonResult that filters using a single wildcard (for want of a better term...): it filters by comparing the string entered in the search bar to the beginning of the strings in the array that fills the table view. What I want instead is to filter on any part of the string (using a 'double wildcard' much like the SQL 'LIKE' operator. Can I implement this using a NSComparisonResult?

On 12 Jan 2009, at 02:32, Michael Ash michael@gmail.com wrote: In thinking about memory usage, where previously I would think of my program in terms of 8 or 16 or 32 bit words should I now be thinking in terms of 64 bit words? That is, should I think of my available internal memory space as effectively being 500MB words? No, this makes no sense. You have 2GB of memory. If you're working with 64-bit words then it makes sense to think of your memory as being roughly 256 million words (note: not 500) but that's not the same as 500MB words. Yes, of course. Silly mistake. Similarly, say that I had 100MB of 2 x 8-bit byte integers to save to disk, should I now think that this will be saved as 100MB by 64 bit (i.e. 8 x 8-bit byte) integers? If it is 100MB by 64 bit integers then should I think of compressing the data so as to reduce bandwidth requirements? Just because your machine has a 64-bit processor doesn't mean you're suddenly required to work with 64-bit quantities everywhere. You can still work with 8, 16, or 32-bit quantities as you need. Yes, but my understanding is that this will change when we go into a full 64 bit architecture and as a one man band I would prefer to write code that anticipates the change than to have to change everything later. Also, the documentation http://tinyurl.com/6ceoqz leads me to believe that if I need an address space of more than 4GB then I should be using 64 bit computing. Which one is the most appropriate choice, I couldn't say, but you seem to have this strange idea that your 8-bit integers will somehow magically take up 64 bits of storage just because you're running on a Core2 architecture. It's simply not the case. I'm glad you've flagged this up because one of the reasons for my asking the question was to increase my understanding of what I should and should not be thinking about in this regard. So let me then ask: under the 64 bit architecture, will the standard c types like int, char etc still be available and not give me problems under garbage collection given I define them as strong? Currently I'm defining most my variables as type NSInteger and CGFloat. Is that wrong? Or should I be implementing my numbers as NSNumber? I thought the main purpose of NSNumber was as a wrapper to enable us to put numbers into NSArray etc. Would not using it as the main representation seriously affect computation speed ? What are other people doing? If you have any good links or advice they'd be much appreciated.

Re: Security With Show Package Contents?
AFAIK that would be impossible because someone would just find away around the protection. There has to be a way to unprotect the app otherwise the file system would not be able to access the binary file. If the file system has a way to access it, someone will figure that out and then they will be able to access it. Trying to make an app un-crackable is not worth the time or effort, if it was feasible they would be doing it with OS's like OS X and Windows and even the big guys like Adobe.

Re: Mac Pro memory sizes

Currently I'm defining most my variables as type NSInteger and CGFloat. Is that wrong? Or should I be implementing my numbers as NSNumber? I thought the main purpose of NSNumber was as a wrapper to enable us to put numbers into NSArray etc. Would not using it as the main representation seriously affect computation speed ? What are other people doing? If you have any good links or advice they'd be much appreciated. From what I understand there won't much change for the smaller variable types. Going 64 bit just means that the largest variables available will be larger and that you'll be able to address more memory at a time. There will be some changes in size and alignment in some of the variable types but most of these changes will hardly be noticeable under most circumstances. NSInteger and NSUInteger are designed so that they will best fit the environment which the code is compiled for. If you use them then you generally don't have to worry if you are compiling for 32 bit or 64 bit, these variables are defined with an appropriate size for the environment. If you need to know what that size is then you can use the constants NSIntegerMin, NSIntegerMax, and NSUIntegerMax. NSNumber is an object that holds values for you. You use it when you can't use a plain variable, such as when you need to store a value in a container class that only holds objects, such as NSArray. There is a small performance and memory hit for using NSNumber over a regular variable but if you use them in small amounts and don't allocate and deallocate them like mad then you shouldn't have any trouble. You can learn more about 64 bit computing under Mac OS X here: http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/intro/chapter_1_section_1.html Here is the section on data type changes: http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/transition/chapter_3_section_3.html As you can see in that last link the variable types char, short, and int are staying the same size. Only the variable types long, pointer, and size_t are changing size. This isn't really a big deal but if you are writing code to compile for both 32 bit and 64 bit environments then you might want to do some sanity checks against the max size for the types that are going to change if you think you might run up against these limits in the 32 bit environment. Lastly you can always use the exact-width integer types such as int8_t which are guaranteed to be at least 8 bits in size. These (and many more) are defined in the C99 standard: http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1256.pdf Honestly though, most of us won't have to worry about these details. I'd use NSInteger and NSUInteger unless you are dealing with a lot of very small integers that you need to pack in as little memory as possible. If you need an object instead of a plain variable then use NSNumber or NSValue. - Ken ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

debugging hard-to-locate error in NSApplication delegate
Hi,
Does anyone have working code that shows an application delegate in a
core data document-based app? I'm trying to intercept
applicationShouldOpenUntitledFile: in order to open the last-saved
document. I have code that works, but it causes this error:
*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil
some time between the setting of the delegate, which I did by inserting
this object into the nib and setting the delegate programmatically.
linking from IB did not properly set the delegate (init and
applicationDidFinishLaunching: were called, but
applicationShouldOpenUntitledFile: was never called):
@implementation GreenwoodAppDelegate
- (void) init
{
[super init];
applicationHasStarted = NO;
if (![[NSApplication sharedApplication] delegate]) {
[[NSApplication sharedApplication] setDelegate:self];
}
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
applicationHasStarted = YES;
}
- (BOOL)applicationShouldOpenUntitledFile:(NSApplication *)sender
{
// On startup, when asked to open an untitled file, open the last opened
// file instead
if (!applicationHasStarted)
{
// Get the recent documents
NSDocumentController *controller =
[NSDocumentController sharedDocumentController];
NSArray *documents = [controller recentDocumentURLs];
// If there is a recent document, try to open it.
if ([documents count] 0)
{
NSError *error = nil;
[controller
openDocumentWithContentsOfURL:[documents objectAtIndex:0]
display:YES error:error];
// If there was no error, then prevent untitled from appearing.
if (error == nil)
{
return NO;
}
}
}
return YES;
}
@end
I borrowed the code in applicationShouldOpenUntitledFile: from a helpful
blog entry, can't remember where.
Thanks,

Re: [SOLVED] NSComparisonResult, 'double wildcard'
Again, I solved it myself. A little embarassing. But hey, I'm just
starting..
If anyone else might wonder how I got it right: I used the
RangeOfString method of NSString to get a range and then add the
object to the filtered objects array if the range's length is greater
than zero:
for (cellTitle in speciesArray) {
if([cellTitle length] [searchText length]) continue;
NSRange range = [cellTitle rangeOfString:searchText
options:NSCaseInsensitiveSearch range:NSMakeRange(0, [cellTitle
length])];
if (range.length 0) [soortenFiltered
addObject:cellTitle];
}
The first line is to prevent NSRangeExceptions when a very short
string enters the loop as comparison base.

Martijn

Hi all,
I'm looking at the TableSearch example to implement a similar view
with a UISearchBar which essentally should act as a filter for the

The TableSearch example implements an NSComparisonResult that
filters using a single wildcard (for want of a better term...): it
filters by comparing the string entered in the search bar to the
beginning of the strings in the array that fills the table view.
What I want instead is to filter on any part of the string (using a
'double wildcard' much like the SQL 'LIKE' operator.
Can I implement this using a NSComparisonResult?

So let me then ask: under the 64 bit architecture, will the standard c types like int, char etc still be available and not give me problems under garbage collection given I define them as strong? Yes, they are all identical to what they were before, with the exception of 'long', which becomes a 64-bit quantity. I don't know what your GC question is about, as GC only affects pointers. Let me briefly explain what 64-bit is all about, because this seems to be the major point of confusion here. In a 32-bit processor, pointers are 32 bits long. Since 2^32 = 4 billion and change, this means that you can address about 4GB of memory. Also, usually but not always, on a 32-bit processor the largest native integer quantity is 32 bits long. Usually there is software support for 64-bit integers but it suddenly becomes significantly slower because the CPU can only deal with 32 bits at a time. In a 64-bit processor, pointers are 64 bits long. Since 2^64 = really huge, that means you can address a really huge amount of memory (it's equal to 4 billion and change squared). You also get native support for 64-bit integers. That's it! Pointer size and native 64-bit integers are the only difference between the two! Your chars don't suddenly expand from 8 bits to 64 bits. Your floats don't suddenly expand from 32 bits to 64 bits. (On Mac OS X your longs do suddenly expand from 32 bits to 64 bits, but int still gives you a 32-bit integer.) The only difference is the size of pointers and, sometimes, the ability to do native math on 64-bit integers.

@loader_path and @executable_path

I also thought it was a project setting so i created the project again from scratch (it's small) but I still got the error, this led me to believe that it is an XCode setting so I reinstalled dev tools and the error still remains. I did some checking in my build and my Frameworks are under Contents/ Frameworks/* In my project directory I created a directory called /Frameworks/* and put the frameworks there. I am not sure if this is the best way to use a framework by including it in my Bundle but I am not sure how else to do this. I guess I could just put all external (non osx frameworks) in a directory on my computer and link them. I have to mention that these errors do not seem to stop the frameworks from working when i run the build. Sparkle still does the updates etc, just a bit odd to have the errors at all.

If a button never works *by design*, a button is the wrong choice for a UI element ... unless, of course, you're creating some sort of UI mockup generator app or something similar that merely draws representations of OS X UI elements. Then again, it wouldn't matter whether the button does anything or not since it'd not be clickable anyway. To answer your question, though, you'd need to override the button's drawing to always draw the enabled state, ignoring the control's actual state. Or, you could let the button allow clicking and simply do nothing. Then it wouldn't appear as broken as if it appeared enabled and didn't even accept a click. The thing to consider is that a user encountering such a control will assume your application is buggy because it doesn't behave properly.

Re: Bonjour server with multiple clients
Let's see if I'm understanding things correctly... The NSNetService publishes on a port and the server creates an NSFileHandle (fh1) for the NSNetService to begin listening to connection attempts. This fileHandle is listening on the same port on which the netService was published. An NSNetServiceBrowser on the client finds the NSNetService and notifies via its netServiceBrowser:didFindService:moreComing: delegate method. The client attempts to resolveWithTimeout to the netService. If the resolving succeeds, then the client attempts to connect to the server by creating an NSFileHandle init'd with a fileDescriptor gleaned from the [netService addresses]; This now opens a port on the client. (This is where things start getting fuzzy) The server, meanwhile, is notified that someone is trying to hook up to fh1, and gets a new fileHandle via the notification object sent along in the NSFileHandleConnectionAcceptedNotification. Is this new fileHandle different from the original fileHandle on the server? Is this new fileHandle operating on a different port than the original? Is this even the proper way to be going about this? Am I anywhere close to getting this working? Thanks a ton!

Re: Using UIImageView for animations
On Jan 10, 2009, at 12:01 PM, Alex Strand wrote: I'm taking a set of 10-20 jpegs that I'd like to animate. I started out just using a UIImageView using setAnimationImages: and everything worked fantastically in the simulator but testing it on my device basically makes it slow to the point where it is unresponsive. I've done some searching around and some people indicate that they are able to use CALayers to get this same effect but before going down that path I thought I would ask you folks. How well this will work is highly dependent on how large each of these images are. Assuming that they are full screen in size (since you mention a performance issue) then 1 JPEG will decompress to about 600K, and thus 10-20 to between 6-12MB. This is a LOT of memory, and you are likely to see many different issues (although performance in this case would likely be due to having a number of other views or cached images also loaded). UIImageView basically does the same thing that you would do with a CALayer to animate images in most cases anyway. There are alternative means by which you can animate an image via a CALayer, but it comes with other restrictions (primarily on image size). On Jan 11, 2009, at 9:04 AM, Glenn Bloom wrote: I don't think I see this issue in my own code using UIImageView with a like number of JPEG's. How large are yours? For a variety of reasons, I have found that optimizing mine as 150KB or less each is acceptable for 480 * 320 pixel images. It sounds like you are considering file size. File size is irrelevant in terms of graphical performance of compressed image formats, as the images will need to be (at least partially) decompressed for usage. In the case of a fullscreen JPEG image, it will be fully decompressed into a 32-bit per pixel format, which means the actual memory usage is 320x480x4=600KB. If you are seeing acceptable performance, then you are likely not pushing up against the maximum amount of memory the graphics subsystem can reference (24MB) and thus not seeing the performance cliff that going past that limit causes. On Jan 11, 2009, at 10:06 AM, Robert Marini wrote: As Glenn indicated, this is largely a factor of the size of the images. Layers are considerably lighter weight than Views (with the associated functionality loss). Views are based on Layers, so in that respect a view is heavier than a layer, but in general usage terms it is not so much so that I would consider using a layer over a view if I needed any feature that a view might offer. Of course, doing what you want to do - depending on the animation involved - might simply be having two image views and animating between then while changing their image backings (UIImageView is the presentation layer for a UIImage and so it is generally most appropriate to have only the max number of UIImageViews that you need to display at once in memory). This might be an acceptable solution, although to control memory you should not use +imageNamed: to load these images (and instead use imageWithContentsOfFile:) as you would likely run into the exact same performance problem if you did. This may also end up with other performance issues unfortunately. -- David Duncan Apple DTS Animation and Printing ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: dragging images to the finder

NSRuleEditor bindings
Hello, Has anyone achieved to use NSRuleEditor with the rows bindings. I can use it successfully when it's binded to an ivar of a controller object. Now i'm trying to bind rows to a NSArrayController. The first time I select an object of the NSArrayController , the rows appear correctly , then when I select another object, every rows disappear and I can't even add new rows programatically. Is there any sample code of NSRuleEditor+bindings somewhere, I can't find anything in the doc.

Re: Disabled button looks like enabled
The button should be disabled by design. It don't intend to interact with a user at all. This is exactly the point Ricky was making. If a button never works *by design*, a button is the wrong choice for a UI element I don't like to discuss ideological part of the thing, I ask only about a technical implementation. you'd need to override the button's drawing to always draw the enabled state, ignoring the control's actual state.

leads me to believe that if I need an address space of more than 4GB then I should be using 64 bit computing. True.

Then simply subclass NSButton, add an ivar called fakeEnabled, then
override the mouseDown and mouseUp events to do the following:
-(void)mouseDown:(NSEvent*)event{
if (fakeEnabled==NO){
[super mouseDown:event];
}
}
Do the same for mouseUp, and just have a getter and setter for

Why not just create a picture of an enabled button (say, a JPG) and display that? If you need text, you can create a blank button and put a label over it which you can then change...etc...

Re: Mac Pro memory sizes
On Jan 12, 2009, at 9:23 AM, Michael Ash wrote: That's it! Pointer size and native 64-bit integers are the only difference between the two! In addition to what Mike said, the transition from X86 to X86-64 includes a few other benefits besides larger pointers and native integers. The number of registers were doubled, and the calling conventions were changed so that 80% of the time function/method arguments are stored in CPU registers instead of being placed in a four-byte-aligned position on the stack. And that 20% of cases only happen when you pass in a structure larger than 128 bits, or pass in an unaligned structure, or have a function that takes more than 6 arguments. So typically a program ported from X86 to X86-64 will run just slightly faster, especially if the program passes around a lot of 64- bit arguments. This doesn't apply to the PPC64 architecture, which is almost unchanged from PPC, and so PPC64 programs are typically slower due to the extra overhead.

thought my Greenwood.xib was the main nib, instead of MainMenu.xib.
Putting the app delegate in mainmenu.nib and linking in IB causes
expected behavior, and removes the exception.
Thanks for all of the help, that exception trick will be extremely
useful, I run into track the exception source all the time, although
usually it's much easier to debug.
Thanks,
Greg

NSTableColumn won't display int values; currently displaying as Yes(/No) (which I didn't think possible)
Hi, I have a simple table bound to an array controller which manages a list of custom objects. One of the table columns is bound to a count property of the custom object; the count property is accessed via a getter that returns a calculated primitive int. For weeks, this table worked as expected and displayed the count value in the appropriate column. At some point, the column stopped displaying values. I checked the bindings, which are fine. As an experiment, I removed the NSNumberFormatter I had associated with the column. When I did this, the column started displaying Yes or No in every row. (No for zero, Yes for everything else, as you'd expect.) I tried adding a new column to the view and binding it to the same value, in case a default somewhere had been changed, and I get the same result. The funny thing, is, there are times I would like to render Yes and No for BOOL's, but I thought a NSValueTransformer was required to do that. At the moment, I'm in a position where I'm considering using a value transformer to get the normal behavior of displaying an int as an number. Did I accidentally enable some ability to display int's as Yes/No, and, if so, how do I turn it off? And on again, because I know I'll want it somewhere else, later. :-) TIA, Doug K; ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Disabled button looks like enabled
But it will still visually respond to mouse clicks, which is not desired, in my interpretation of the problem statement. [[theButton cell] setHighlightsBy:NSNoCellMask] presumably takes care of that -- but then the user might still be able to select the button by tabbing to it. If a single NSButton is used, I think the easiest thing is to disable it and then override its drawing behavior, as I. Savant suggested. But it depends on the context of what the application is trying to do. If the application displays a screenful of different fake UI components (for example, as a sort of mockup, as I.S. posited), it would be impractical to have a subclass for every control/cell. In that case, some sort of offscreen drawing makes sense -- draw the whole window/view offscreen, not even bothering to disable the controls, and blit it to the real window. --Andy On Jan 12, 2009, at 1:35 PM, Dave DeLong wrote: So what you're saying is you want a button that doesn't do anything?

Re: Need help on nsfontmanager.
Hi, I want to use multiple font traits . I.e..,making the text both bold and italic (LIKE BOLDITALIC ) Is this possible? It depends on the font. Some fonts have just a regular form, others have a bold form as well as a regular form, others an italic form, a bold form, and a bold+italic form. If there is a bold+italic form of a particular font you can set it. If you play about with TextEdit you will be able to see the different forms that various fonts have. Helvetica has: - Regular (normal) - Oblique (italic) - Bold (bold) - Bold Oblique (bold+italic) A font like Impact has just a Regular Hope that this helps Best regards Alan Shouls ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

didReceiveMemoryWarning doesn't release view...
Hi there. I'm using a table view controller inside a navigation controller wich is a view controller of a tab bar controller. As I want take care of memory warnings, I put the table view in a separated nib file, setting the file's owner class to my table view controller subclass and all other thinks (view outlet, nib file name, etc). It seems to work fine but when a memory warning is generated using simulator, the table view is not released. I set breakPoints on setView and loadView and they are called only first time view is needed. I read that the view is released if it doesn't have a superview but I discovered my view has a UITransitionView superview ¿...?. Please, is there someone who know what could be going on?. I'm stuck with this silly thing. Tx in advance. -- Oscar A. Alvarado ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Release vs. autorelease
Hi, In places other than dealloc where memory needs to be released (e.g, reassigning pointer to objects), is there a difference in doing autorelease or release of the object in terms of perfomance etc. ? I can see that the memory is released immediately in one case whereas in the other it is slightly delayed. Is there any other difference ? What is the right thing to do ? thanks mohan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

And yes, if you don't have a good reason they will certainly point that out. I see there is unavoidable problem with my fake button and Accessibility tools which may happens. I planned to use it to emulate gradient bottom bar (under Source List control), looks like in Mail.app. I created three buttons, two gradient action-buttons and one gradient non-clickable button with image aligned to right. This image is a three lines which act as additionalEffectiveRectOfDividerAtIndex: of NSSplitView. It looks really nice but the fact that is a button...can it hurt people with Accessibility devices? Really, I don't like all these additional libraries that try to emulate gradient bottom bar, because they redraw these controls by itself, and I would like to use only Apple controls. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hmm, I don't know internals of Cocoa, I hypothesized that putting a button in a disabled state can remove focus areas handled by mouse or something else, which can save a little system resources without big pain. Are you 100% sure that disabled and enabled buttons takes identical amount of system resources?
