Re: NSSocketPort initRemoteWithTCPPort is never valid

If I use that same port in any other way (such as NSFileHandle) it doesn't work. The error it gives is: [NSConcreteFileHandle writeData:]: Bad file descriptor (when I use initWithFileDescriptor:port.socket ) An NSSocketPort is intended for use with Distributed Objects and NSConnection or, at least, to communicate with another NSSocketPort at the other end. You would use the NSPortMessage class for sending data in the latter case. I don't think it's suitable for creating an arbitrary socket connection to a remote port. The particular problem you're encountering is probably due to this sentence in the documentation of -initRemoteWithTCPPort:host: A connection is not opened to the remote host until data is sent. It's quite possible that the socket file descriptor isn't even allocated until then, either. Even if the file descriptor has been created, connect() hasn't been called at the point where you're trying to init your NSFileHandle object with it. And since you're trying to use the file descriptor rather than the NSSocketPort object from that point on, there's no opportunity for NSSocketPort to establish the connection. It can't very well hook into the system calls and magically connect the socket when something tries to write through the file descriptor. In other words, what you're trying to do isn't a supported usage pattern. Ideally, I'd like to be able to use NSFileHandle (or something very similar) on both ends of the connection. Any thoughts/suggestions? Look into using streams (NSStream and friends).

The app I'm using is cross platform, open source, programmed in C and uses a makefile to build. Any suggestions? There's probably no one best way, but you have several choices. Bear in mind that 'app' really refers to the packaging of code, rather than the code itself. You'll need to repackage it to use as part of another app. Typical ways would be as a statically linked library or as a dynamically linked library or framework. I'd build the external app in a separate Xcode project so that you can work out the kinks of doing so in isolation. Then, when it's building cleanly, add the entire project to your derivative project and set up dependencies so that the first gets built, generates its products which are then included in the second, which then builds, linking to the library the first one built. This sounds a bit convoluted but it's quite straightforward. Alternatively if the source is just a few files this might be overkill - you could just add the files directly to your source. However most open source projects I've come across seem to have extended chains of dependencies which make this approach unattractive, as you'll end up dragging in hundreds of other files just to get it to compile. Doing that in a separate project makes managing that part of the code a lot easier, I've found. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

10.4 vs 10.5 SDK - some problems in compilation
Hi, All, I'm rather new in XCode and Cocoa, so maybe it's my misunderstanding. Am I correct in my understanding, that I need to select 10.4 SDK in XCode project menu to create an application, compatible with both Tiger and Leo? I've got few errors in compilation when I choose 10.4 SDK. Some of these errors, like NSUInteger and CGFloat missing, I've fixed by appropriate basic types substituting. Nevertheless I still have one uresolved problem - kVK_ constants are not found in 10.4 SDK, though they're OK with 10.5. I've tried to search in Google, but the only I've found was some FAQ, where it was suggested to use absolute path to the header file. I've tried it, but without luck. Though I use #import/System/Library/.../Events.h (what is shown in Get Info for that header in Finder) I still get the same error. What is strange for me, all works OK even without this #import clause when I'm using 10.5 SDK. Any help would be appreciated.

Removing an NSOpenGLView causes default background to be drawn.
Hi, When I remove and NSOpenGLView or when I close a window that has an NSOpenGLView that area is drawn over with his default background color (in my case this is Black). This only happens depending on how long it takes to replace or close that window. I can see it in my app when I quit because that takes a while. I have a few ideas on how I can get rid of this visual effect. But I wanted to poke around if other people have seen it and solved it. The effect that I see can be easily tested with any simple NSOpenGLView application. I tested an standard cocoa sample app: http://www.mataderu.com/xphere/info/cocoa_tut01/index.html Cocoa Appkit is calling CGLClearDrawable on the opengl context before it is getting removed then later on it removes the context and calls CGSRemoveSurface this last call when that is finished calling causes the black (or white depending your setting) area to appear. To simulate the slow quiting/replacing i can demonstrate it with Debugger trick: I run it with the debugger and put a breakpoint at CGSRemoveSurface. I quit the application, then it hits that breakpoint, and the window still looks normal. Then when I step out of this method it becomes white. Which is like the NSOpenGLView standard background color. Here is the stack trace: #0 0x954711ad in -[NSSurface _disposeSurface] #1 0x9679e53c in _nsnote_callback #2 0x912d764a in __CFXNotificationPost #3 0x912d7923 in _CFXNotificationPostNotification #4 0x9679b690 in -[NSNotificationCenter postNotificationName:object:userInfo:] #5 0x967a4ee8 in -[NSNotificationCenter postNotificationName:object:] #6 0x9553c710 in -[NSWindow _close] #7 0x91364be5 in -[NSArray makeObjectsPerformSelector:] #8 0x955dab93 in -[NSApplication _deallocHardCore:] #9 0x955d98b1 in -[NSApplication terminate:] #10 0x954fa4cb in -[NSApplication sendAction:to:from:] #11 0x955a9108 in -[NSMenu performActionForItemAtIndex:] #12 0x955a8e0d in -[NSCarbonMenuImpl performActionWithHighlightingForItemAtIndex:] #13 0x955a8a93 in -[NSMenu performKeyEquivalent:] #14 0x955a7338 in -[NSApplication _handleKeyEquivalent:] #15 0x954c40fb in -[NSApplication sendEvent:] #16 0x9542162f in -[NSApplication run] #17 0x953ee834 in NSApplicationMain #18 0x1b64 in main at main.m:13 Any ideas on how I can get rid of this last minute view clearing?. marc ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I've got few errors in compilation when I choose 10.4 SDK. For your case you'll need to set the SDK to 10.5 so that you can use Leopard-specific APIs.

NSUInteger and CGFloat are only defined in the 10.5 SDK, even though they're perfectly fine data types on a 10.4 system. Any 10.5 C-style functions or constants will be weak linked so you'll need to check for their existence at runtime. Likewise you'll need to check for the existence of 10.5-only Cocoa methods using -respondsToSelector:.

Re: Integrating with another app
Thanks for the advice. I currently have the external app added to my project as an external target which works well with the makefile. Is it possible to use a makefile with a dynamic or static library or will I have to translate the makefile into something else?

The app I'm using is cross platform, open source, programmed in C and uses a makefile to build. Any suggestions? There's probably no one best way, but you have several choices. Bear in mind that 'app' really refers to the packaging of code, rather than the code itself. You'll need to repackage it to use as part of another app. Typical ways would be as a statically linked library or as a dynamically linked library or framework. I'd build the external app in a separate Xcode project so that you can work out the kinks of doing so in isolation. Then, when it's building cleanly, add the entire project to your derivative project and set up dependencies so that the first gets built, generates its products which are then included in the second, which then builds, linking to the library the first one built. This sounds a bit convoluted but it's quite straightforward. Alternatively if the source is just a few files this might be overkill - you could just add the files directly to your source. However most open source projects I've come across seem to have extended chains of dependencies which make this approach unattractive, as you'll end up dragging in hundreds of other files just to get it to compile. Doing that in a separate project makes managing that part of the code a lot easier, I've found. --Graham smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Efficiency of loading Localizable.strings and NSUserDefaults
This is not a help, the code doesn't work question, but more a general question to help one write better Cocoa code. Imagine my program requires a large amount of localizable strings. In many cases (ex. error codes), I have a string associated with an integer value. For some of these, I could create an array of strings, and when I need a specific String #18, I would go to the 18th element of the array. For the sake of this discussion, I am using C array structure, not NSArray objects. I could just pre-load all the strings in at startup, so they are always there. This takes a bit more memory and startup time, but has the advantage that the strings are always there. Or I could set the elements to the array to nil, and the first time I need a specific string, I load that string from the Localizable.strings file, use it, while setting the element of the array to the string for future use. Thus once I use a string, it is available for quicker access a second time. Assume for this argument, that I am using writing some user interface where I actually need the strings fast. Going to disk ever time is not an option. Either of these approaches can work, but they are based on the premise that retrieving the string from the Localizable.strings file causes no buffer of it's own? Is this true? When I invoke -localizedStringForKey:value:table: (or the other variations of NSLocalizedString), is the entire Localizable.strings file read into memory? Is it thrown away at the end of the call? Or is the localized version of all the strings kept in memory for use? Is the entire file read into memory, or If it is kept in memory, it makes no sense for me to store the strings in an array. Disk access is slow, but extracting a specific string from a block of data already in memory is fairly fast. In fact, when I load in 10 strings from the Localizable.strings file, am I reading the entire file in 10 times? I can not image this is the case, there must be some buffering happening. Anyone has some comments or ideas about this? Possibly someone with some inner understanding of how localized strings are read? Related to this idea, is the similar case of reading strings from and to the NSUserDefaults object (preferences). Should I read all my preferences (Strings, integers, boolean) in at startup? Or should I read them when I need, assuming that Cocoa is keeping them in memory? Apple has been recommending that applications save the preferences to the NSUserDefaults object when the preferences get changed, and not as shut down. This prevents loss of preferences due to crashes or forced quits. Another reason was explained to me at WWDC. For the iPhone, you do not want to take up any time, when your applications switches out to another. Save the preferences when the user changes them, you have the time then. Again, anyone has thoughts or comments about the inner working of NSUserDefaults? Thank you!

Reference Count Underflow when Writing PDF
I have a PDF that I've loaded, combined with another PDF, and now I'm ready to save the result as a new file. My program is using garbage collection, but I understand that PDFKit is not garbage collected. The problem is that I get reference count underflow error when writing the PDF. Here is some code that is shorter, but creates the same problem I'm having: // Get PDF from disc NSData *savedData = [[NSData alloc] initWithContentsOfFile:@oldfile.pdf options:0 error:error]; PDFDocument *savedDoc = [[PDFDocument alloc] initWithData:savedData]; // Write saveDoc to file [savedDoc writeToFile:@newfile.pdf]; Actually, there is no problem when writing the file: newfile.pdf is intact after the operation. But I get the following error in the console: malloc: reference count underflow for 0x13464c0, break on auto_refcount_underflow_error to debug. And when I break on auto_refcount_underflow, I get the following stack: #0 0x94721a40 in auto_refcount_underflow_error #1 0x9472d8e4 in Auto::Zone::dec_refcount_small_medium #2 0x9472d9b0 in Auto::Zone::block_decrement_refcount #3 0x931da50c in CFRelease #4 0x904bfe4c in -[PDFDocument(PDFDocumentInternal) writeToConsumer:withOptions:] #5 0x904bd9fc in -[PDFDocument writeToURL:withOptions:] #6 0x904bd97c in -[PDFDocument writeToFile:withOptions:] #7 0x6b60 in -[MyDocument openPanelDidEnd:returnCode:contextInfo:] at MyDocument.m:495 Now, #3 suggests there is a release going on that shouldn't be; or at least there should be an extra retain in my code. But when I add CFRetain(savedDoc); before writing the file, the error still persists. I've read the Semantics section of Using Core Foundation with Garbage Collection, but I don't see a solution to this problem there (I'm not saying it's not there, just that I don't quite see it).

Japanese Language
Ok, I lucked out and got a great chance at releasing a bit of software in japan. The problem is that it is 50/50 client to web.

I have spent quite a bit of time googling and am still not sure but is the japanese data that will be sent from my application to my server utf-8? Or is it utf-16 as I for some reason thought. Everything sent to the server is pre encoded for transport, stored and then unencoded by the app so I feel at least a level of confidence that if I encode with the correct string encoding my server side will just accept and store the data.

Inspecting the instance variables of an NSError (or any other Cocoa object, for that matter) won't likely get you very far. Using the debugger, step past the save:, then type po err at the debugger console. That will get you a human-readable summary of the error, but not enough detail. However, that summary will include the address of the NSError's userInfo dictionary. Say the address is 0x123456; type po (id)0x123456 into the console. You will be presented with a dump of the dictionary, from which you can (probably) glean the details of what went wrong. Thank you for your reply Fritz.

When the tooltip appears a menu is available the first item of which is Print Description which seems to do the same job as po although I would be happy to know if that is true or whether po is better. So the problem is that trying to po the NSError leads to a failure, which is why I surmised that the error was not? properly initialized.

On the iPhone, all textual data in memory (e.g. NSString) will be UTF-16. If you store data in files on the iPhone, you'll want to store them in some well-known encoding. This will typically be UTF-16 especially if you simply archive NSString objects. As for the transport, I would highly recommend UTF-8 as no byteswapping is needed. For most Latin-based data, the number of bytes taken up in UTF-8 will be less than what is used by UTF-16. For Japanese (and many other languages), the number of bytes of UTF-8 will be more than UTF-16. Just wanted to point that out in case you have insanely strict bandwidth requirements.

Re: Reference Count Underflow when Writing PDF
In an effort to get out of this problem, I also thought I might just take a data representation of the PDFDocument object, and write the data to a file. I get the same problem. Here is what I tried, substituting for [savedDoc writeToFile:@newFile.pdf] below: NSData *myData = [savedDoc dataRepresentation]; [myData writeToFile:@newfile.pdf options:0 error:error]; The malloc error is triggered on the -dataRepresentation line. So, three questions: (1) Contrary to my first message, it appears to me now that PDFDocument inherits from NSObject. So, i shouldn't have to do any special memory management, right? (2) The malloc error doesn't seem to stop the program, and everything is written to the appropriate file. Can I just leave the code as it is and ignore the error, or will it eventually catch up with me?

And when I break on auto_refcount_underflow, I get the following stack: #0 0x94721a40 in auto_refcount_underflow_error #1 0x9472d8e4 in Auto::Zone::dec_refcount_small_medium #2 0x9472d9b0 in Auto::Zone::block_decrement_refcount #3 0x931da50c in CFRelease #4 0x904bfe4c in -[PDFDocument(PDFDocumentInternal) writeToConsumer:withOptions:] #5 0x904bd9fc in -[PDFDocument writeToURL:withOptions:] #6 0x904bd97c in -[PDFDocument writeToFile:withOptions:] #7 0x6b60 in -[MyDocument openPanelDidEnd:returnCode:contextInfo:] at MyDocument.m:495 Now, #3 suggests there is a release going on that shouldn't be; or at least there should be an extra retain in my code. But when I add CFRetain(savedDoc); before writing the file, the error still persists. I've read the Semantics section of Using Core Foundation with Garbage Collection, but I don't see a solution to this problem there (I'm not saying it's not there, just that I don't quite see it). Any help would be greatly appreciated. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Dictionary interface

An API that finds words using a soundex- type function would be nice. That, plus a plugin method to add a UI item similar to Dictionary and Thesaurus would be ideal. It's off at a tangent to your question, but I have written a nice NSString category for matching strings based on Soundex and Jaro- Winkler distances that works quite nicely. It only compares single strings rather than search against a list of words, but it's a step in the right direction.

Re: Efficiency of loading Localizable.strings and NSUserDefaults
On 16/07/2009, at 6:45 AM, Development wrote: Anyone has some comments or ideas about this? Possibly someone with some inner understanding of how localized strings are read? Optimise later. You are fretting about the speed of loading strings to the point where you are considering your own look-up scheme - a problem that Cocoa has already solved for you. And all without doing any measurement (presumably - you don't mention any profiling figures). Here's a fact - *drawing* a string takes aeons compared to the time needed to get that string in place ready to be drawn. So no matter how fast you load the strings, your performance will be graphics/drawing time bound. You mention these being error strings - I find it hard to imagine why performance here matters. Are you wishing to display errors at hundreds of frames per second? How is the user expected to read them? Keep your code simple - use the NSLocalizedString macro or one of the localised string loading methods and worry about performance later if it proves (by actual measurement) necessary. Again, anyone has thoughts or comments about the inner working of NSUserDefaults? Same thing. Read from the defaults as needed. As far as I can tell, NSUserDefaults is basically a disk-backed dictionary, and is kept in memory. Access can be assumed to be fast, or at least fast enough, unless actual measurement shows otherwise. As for flushing to disk every time in case of a crash, I'd say don't even if that is Apple's apparent advice [citation needed]. Your app should not crash - concentrate on fixing it if it has a tendency to, rather than introduce performance bottlenecks that could affect your whole app all the time, just in case. Two wrongs don't make a right. Don't sweat the details - code simply. Measure. Optimise *if necessary*. I bet you'll find it won't be, and you've saved yourself a ton of work (and sweat). --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[iPhone] Encrypting data of an iPhone Application / Converting J2ME App functionality
Hi, I am still learning iPhone application development and I want to convert a J2ME trading client application to an iPhone SDK application. I have already developed an iPhone application that did not have any encryption published at Apple AppStore. I have good knowledge with J2ME so I could understand what is happening within it. But I have an issue when I am thinking about converting that to iPhone one. J2ME application uses BouncyCastle http://www.bouncycastle.org/J2ME crypto API to encrypt strings. The client sends this to J2EE server. I haven't got much idea about encryption stuff. And I found that iPhone has CommonCrypto called library to encrypt information. Could anyone kindly tell that could I use this for my purpose. I mean will it work with the Java Server. I do not have much idea about Server part as well. But I could understand the J2ME client. I would be glad if any of you kindly point out some places or method to do encryption I need for my application. Will it work with Common Crypto ?

Re: Printing a View [solved]
Thanks Matt, for the advice. I followed your links, and found the
best way, for me at least, to print what I wanted was to create a view
in IB, populate a custom view with text fields and tables, and then
resize that view for printing.
For those who are working on a similar problem, I created new view
controller object from -printOperationWithSettings:, and that view
object in turn creates the view that I want to print. That view
implements various other subviews, but I was still having problems
breaking pages at appropriate points. The subviews, however, can say
where they should be broken by using -adjustPageHeightNew:. In my
NSTableView subclass, which was the main element in the view, I
implemented that method as follows:
-(void)adjustPageHeightNew:(CGFloat *)newBottom top:(CGFloat)top
bottom:(CGFloat)proposedBottom limit:(CGFloat)bottomLimit
{
*newBottom = proposedBottom;
NSInteger indexCount = [deduction lineCount]-1;
for (NSInteger i = indexCount; i0; i--)
{
NSRect rowRect = [self frameOfCellAtColumn:[self
columnWithIdentifier:@MyColumn] row:i];
float bottomOfRow = rowRect.origin.y + rowRect.size.height;
if (bottomOfRow proposedBottom)
{
*newBottom = bottomOfRow + 1.0;
break;
}
}
}
So, the for loop just goes through the table and adjusts *newBottom so
that it breaks at appropriate places. There is probably some more
efficient way to check where the page should be broken, but the above
implementation works just fine.

Working code is always worth much more than theoretical code, but if your table has a constant height per row, you can simply take the proposed page height modulo the row height to find the amount over, then subtract it to get the new page height that will fit an exact whole number of lines. It will be much faster than looping if you have many lines. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Japanese Language
Ricky Sharp wrote: As for the transport, I would highly recommend UTF-8 as no byteswapping is needed. For most Latin-based data, the number of bytes taken up in UTF-8 will be less than what is used by UTF-16. For Japanese (and many other languages), the number of bytes of UTF-8 will be more than UTF-16. Just wanted to point that out in case you have insanely strict bandwidth requirements. Depending on what the server and client are using as the transport protocol, it may support a compressed encoding. For example, HTTP 1.1 has a gzip option for content encoding (also compress and deflate, but in my experience gzip is more often seen). See sec. 3.5 Content Codings of RCC2616. http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html In general, a client states its supported encodings and the server chooses, or the two participants negotiate. Again, this depends on what the transport protocol is: not all of them support compression. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
