[Moderator] iPhone SDK still in effect
iPhone SDK -- Until an announcement is made otherwise, developers should be aware that the iPhone SDK is still under non-disclosure (section 5.3 of the iPhone Development Agreement). It can't be discussed here, or anywhere publicly. This includes other mailing lists, forums, and also blogs. Violating the NDA will result in WWDR being notified of the breach. Further action is a their (and legal's) discretion. The iPhone SDK situation is somewhat different than a Mac OS X release, in that a Mac OS X release includes a copy of the developer tools with the distribution. The iPhone OS 2.0 release on devices and as an upgrade does _not_ include the development tools. As a result, the SDK is not automatically considered public because the release has occurred. Section 5.3 of the iPhone Development Agreement remains in force at this time, and will so remain until iPhone Developer Program members are specifically and personally notified by an authorized representative of Apple. Xcode 3.1 - iPhone SDK requires Xcode 3.1 so it contains it (because it won't work without it). Xcode 3.1 is available indepently of the iPhone Developer Program and its nondisclosure agreement, so it's available as a download separately from the iPhone SDK,. Whichever you choose, the Xcode build and installation is identical. But you still can't discuss the iPhone SDK. Questions about Xcode and Interface Builder are best addressed to the [EMAIL PROTECTED] mailing list. SnowLeopard NDA === The SnowLeopard seed is under non-disclosure and can not be discussed here. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Need help with predicate format
Thanks. Maybe I should have made myself a little more clear. I don't want to iterate over the array, but filter the array using a NSPredicate. I'm looking at the Predicate Programming Guide, which only gives basic guidance, and the docs for NSExpression. It has several class methods that sound right (expressionForEvaluatedObject:, expressionForAggregate:, expressionForSubquery:usingIteratorVariable:predicate:, expressionForFunction:arguments:) but provides no examples how to use them. Unfortunately Google has very little to say on this subject too. To repeat the problem: I want to check the value of all keys in every dictionary contained by an array and see if they match my search string. A workaround to compensate for my syntax ignorance would be to add a new instance method to my custom class that simply return all the values I want to check in a single array. Then I could query it with a simple single-relationship predicate: NSPredicate *predicate = [NSPredicate predicateWithFormat:@(%@ IN values, searchString)]; NSArray filteredArray = [myArray filteredArrayUsingPredicate:predicate]; But somehow I believe there is a more direct way to do this, without having to add a new helper method to my class? I'm perfectly happy with a 10.5 only solution. Thanks.

Re: Setting conditional breakpoint on Cocoa method?
There's probably a better way, but you could create an if statement
containing a log message (or something) that has a breakpoint (e.g.:
if (aString == nil)
{
NSLog(@blah) -- Breakpoint here
}
)
Kinda stupid solution, though.

Is there a better/cleaner way? Quartz does not have current context concept. This is a Cocoa concept introduced by NSGraphicsContext. All Cocoa drawing methods are using the current NSGraphocsContext, so you have to set it to the appropriate value. If you want to use Cocoa method to draw into a CGContext, you have to first create a NSGraphicsContext with it, and then setting this context as current. save/restore state is used to save the context current state (line width, shadow, clipping, colors, ...), not to save the current context. From the Cocoa Drawing Guide: “To save the current graphics state, you use the saveGraphicsState method of NSGraphicsContext. This method essentially pushes a copy of the current state onto a stack, leaving you free to make changes to the current state. When you want to revert back to the previous state, you simply call therestoreGraphicsState method to pop the current graphics state (including all changes since the last save) off of the stack and restore the previous state.” ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

How to get the cursor animation effects - Clouds of smoke when deleting something
I assume that there is a system-wide set of predefined cursor appearances and effects intended to be used by applications to mean particular standard actions. Is this correct? For example, when I drag something outside a view to get rid of it, the cursor shows a vanishing cloud of smoke and plays a special sound. Can I use this (and other) effects in my application and how do I do it? Also, I'd like to use the copy cursor (the arrow with green circle and a plus) outside the drag-and-drop process, e.g. manually set this cursor in mouseDragged event. Is this possible and how do I do it? Thanks ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Setting conditional breakpoint on Cocoa method?
Ah thanks, that's very helpful. One thing that I'm a bit unsure about. If I enter a symbolic breakpoint, will it break on the first instruction of that method or further along? It matters because that doc states: If you've stopped at the first instruction of a routine, the first parameter is at 4 bytes above the stack pointer, the second parameter is 8 bytes above the stack pointer, and so on. The GDB syntax is *(int *)($esp+4), *(int *)($esp+8), and so on. If you've stopped elsewhere in the routine (after the frame has been created), the first parameter is at 8 bytes above the frame pointer, the second parameter is 12 bytes above the frame pointer, and so on. The GDB syntax is *(int *)($ebp+8), *(int *)($ebp+12), and so on. Assuming the first case, wouldn't the offset be 12, not 16? (two implied parameters then the first visible one). The second case would be 16 of course - so I need to know where a symbolic breakpoint actually stops. cheers, Graham On 28 Jul 2008, at 6:47 pm, Jonathan del Strother wrote: On Mon, Jul 28, 2008 at 8:02 AM, Graham Cox [EMAIL PROTECTED] wrote: Once in a blue moon, I get a console message that a nil string was passed to [NSConcreteAttributedString initWithString:] I'd like to find out where this is coming from by setting a breakpoint there, but only for a nil string.

Re: Setting conditional breakpoint on Cocoa method?
I need to break on a Cocoa method that I don't have the source to. If
I had the source, I could just set a breakpoint by clicking in the
margin in the usual way.
Thanks anyway,

sorting two arrays
Hey all... I've got two arrays that are related, so that object 0 in one array corresponds to object 0 in the other array. I'd like to implement a sort based on the values in one array, but to reorder both array so that the order of the two arrays stays in sync and that object x in one array continues to correspond to the same thing as object x in the other array after the sort. I've got a general idea of how to implement the sort, but since I know that there are a few places in the system where array pairs are used like this, I wanted to see if there was any out-of-the-box way of handling this scenario - I'd hate to reinvent the wheel if it's not necessary.

[Newbie] Communication between two Views?
Hello,
I have a question regarding to communication between two Views.
My tableview creates a view in which the user can enter a text. How do
I get the text from the View to my tableview?
The View is created in the following was in my tableview:
- (IBAction)addAction:(id)sender{
if (ncvController == nil)
{
self.ncvController = [[NewCourseViewController alloc]
initWithNibName:@NewCourseViewController bundle:nil];
}
[[self navigationController] pushViewController:ncvController
animated:YES];
}
Can someone please give me an example?
Thank you so much

Somewhere there needs to be a controller that connect to your views and responds to your editing events by getting the value from your view and doing something with it.

Re: Access to events in tight loop?
What you can do is use the NSWindow's nextEventMatchingMask: method to
determine the next event, here you can check for events that should
discontinue your current processing.
So, say if u want to do some processing only while mouse down, and
stop if there is a mouse up while you are doing it then u can do:
- (void)mouseDown:(NSEvent *)event
{
while ([event type] != NSLeftMouseUp )
{
// do processing
// get the new event
event = [[self window] nextEventMatchingMask:NSLeftMouseUpMask];
}
}

On Thu, 24 Jul 2008 21:50:31 +1000, Steven Hamilton [EMAIL PROTECTED] said: Hi Folks, I have a NSTableview with a datasource consisting of an NSArray of dictionaries. One column in my table has an NSPopupbuttonCell. The content and contentValues are bound to a Core Data Account object. I use a name property as my contentValue. I'm having trouble changing the popup button. I know in my datasource I get an index of the selected object and in my setObjectValue datasource method I set the key in the dictionary with this new NSNumber inValue. However, in operation when I change the popupbutton it very quickly changes back to the first object in the list (index 0). Clearly I'm missing something or have set something wrongly in IB. How comes it that you are using both bindings and the tableView:setObjectValue:... datasource method?

Re: Creating a styles menu like the one in the ruler accessory view of NSLayoutManager...
Hmm, Looking into this some more, it seems that the user's favourite styles can be accessed like this: NSDictionary *favStyles = [[NSUserDefaults standardUserDefaults] objectForKey:@NSFavoriteStyles]; Presumably this is what is used to generate the pop-up menu in NSLayoutManager's ruler accessory view. However, given that I cannot find anything on this in the docs, I am guessing that this is undocumented and not recommended? Looking at the dictionary that this returns, it does seem that it would be fairly straightforward to grab the keys (which are the names of the styles) and then go through the inner dictionaries that contain the attributes and apply them to the text selection, but is there a more standard way of getting the styles information for use like this? (Again, I'm trying to create my own format bar rather than use the standard text view ruler accessory view.) My feeling is that this is probably not a recommended route given that I can find no documentation or information on it. Thanks and all the best, Keith --- ORIGINAL MESSAGE --- Hi, I'm fairly sure that this isn't possible without hooking into private methods of NSLayoutManager, but it's worth asking on the off-chance... In a standard rich textNSTextView, the ruler view has an accessory view provided by NSLayoutManager. This accessory view has several handy controls in it - a styles pop-up menu, a lists pop-up menu, an alignment segmented control and so forth. However, for my own app I'm overriding NSLayoutManager to get rid of this accessory view. Instead, I'm providing a Pages-like format bar; the reason for this is that, given that you can split the editor in my app and therefore have two text views visible, you can also have two accessory views visible which can take up more screen estate than necessary; having the same controls in one bar that affects both text views will take up less space and provide a less cluttered experience. Adding most of the controls to this format bar is straightforward - bold, italic, underline, foreground/background colour, alignment etc are all relatively easy. However, it seems that there is no way of grabbing a list of available styles in order to provide a styles menu like the one that appears in the standard accessory view (nor no way of grabbing the lists menu, for that matter). I can just create a button that calls -orderFrontStylesPanel: if necessary, but this will involve more steps for the user (having to go through the sheet to get to the menu), and I'd really just like to provide a list of styles like the one in the standard NSLayoutManager accessory view. Is there any way of doing this? As I say, from surveying the docs and searching online, I don't think it's possible - I think these lists and how the menus are generated by NSLayoutManager's accessory view are all contained in private methods - but I'd love to discover I'm wrong.

The View is created in the following was in my tableview: Search the documentation for the Model View Controller or MVC design pattern. The controller layer allows (requires?) controllers to mediate between your model and view layers. Somewhere there needs to be a controller that connect to your views and responds to your editing events by getting the value from your view and doing something with it.

Re: Getting process table info from within a Cocoa app
Thanks guys. I thought I'd post my solution. The difference between my
solution and the examples on the net that I was able to find is that I
already know the pid -- I just want to see if that pid is still
running, if it's running as root, and if it has a certain name.
Although the Cocoa content is minimal, this might be useful for
someone who might otherwise end up using NSTask and NSPipe to look for
running processes, creating lots of overhead.
Studying sysctl(3), /usr/include/sys/proc.h, and
/usr/include/sys/sysctl.h, here's what I came up with:
#import sys/types.h
#import sys/sysctl.h
#import string.h
#import stdio.h
#define MAXCHARS 8
#define MIBSIZE 4
#define PIDFILE /var/run/some_VPN_pppd.pid
- (BOOL)isVPNRunning {
char line[MAXCHARS];
FILE *fp;
if ((fp = fopen (PIDFILE, r)) == NULL) {
//pid file does not exist; vpn is not running
//NSLog (@vpn is not running 1);
return NO;
} else {
if ((fgets (line, MAXCHARS, fp)) == NULL) {
//pid file exists but is weirdly empty or otherwise
unreadable;
presume vpn is not running
fclose (fp);
//NSLog (@vpn is not running 2);
return NO;
} else {
fclose (fp);
int pid = atoi (line);
//got the pid from the pid file
//get the process table info for that pid
int mib[MIBSIZE];
struct kinfo_proc kp;
size_t len = sizeof(kp);
mib[0]=CTL_KERN;
mib[1]=KERN_PROC;
mib[2]=KERN_PROC_PID;
mib[3]=pid;
if (sysctl(mib, MIBSIZE, kp, len, NULL, 0) == -1) {
//there was a problem getting the process info;
presume vpn is not running
//NSLog (@vpn is not running 3);
return NO;
} else {
if (len 0) {
//there is a running process with that
pid
//is the process owned by root?
if (kp.kp_eproc.e_pcred.p_svuid == 0) {
//process is owned by root
//is that process named pppd?
if (!strcmp(pppd,
kp.kp_proc.p_comm)) {
//VPN IS RUNNING
//NSLog (@vpn is
running with pid = %d, uid = %d, process name

Storing values in dictionary with their address as the key

If I wanted to store an object in a dictionary and set its key as the

Right now I'm doing this:
int i;
for (i = 0 ; i 10 ; i++)
{
NSObject *myObject = [[NSObject alloc] init];
[dictionary setValue:myObject forKey:[NSString stringWithFormat:@%x,
myObject]];
}
The above does seem to work, but the memory address that I get always
seems to be the same.
Any ideas?

myObject is a variable (of type pointer) that is allocated on the

Re: [Newbie] Communication between two Views?
I know how MVC works with one Model, one View and one Controller but I really don´t understnd how the controllers of different Views communicate with each other. Through the model. The controllers of different views do not generally communicate directly. That's a pretty general blanket statement that is most certainly not always the case. Consider (as a very basic example) a master/detail view (without the use of Bindings, especially). Sure there're plenty of reasons I can think of to have multiple controllers (one for the master list and one for the detail view), but for every reason I can think of to separate the controllers in this scenario, I can think of one that strongly suggests keeping them as one. The thing is, in this scenario they'd still need to talk *somehow* (to track the master selection for determining what to show in the detail view) and the model is *most definitely not* the place to track selection in the master view. That is between the view(s) and the controller(s). -- I.S. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I have a number of applications that I would like to port, but redesigning the form or menu layout completely seems to be rather pointless. I am quite willing to rewrite all the code that interacts with the forms or menus, but I am not a graphic designer so form layout is better left to experts who have already done it. All I really want is a tool that will put objects without any connections or code on a form or menu by parsing a MS .RC file, for example Being able to do this would lead to an large increase in the number of Macintosh applications available. I'm not aware of an existing tool, though I've said in other similar threads (some on Carbon-Dev) that it should be possible to write code that does this, as long as the source format is known. Xcode 3 has the XML-based XIB format. You could create a few simple test files, see what XML it generates for the various objects, see how the sizes of these objects differ from their Windows counterparts*, and then write code that reads the RC files and outputs the text needed for an XIB. Rather than attempting to write out a XIB file*, it would be far better to write an IBPlugin, that adds a menu item to the main menu, and then uses API from InterfaceBuilderKit.framework's IBDocument class to construct an Interface Builder document from a RC file. This abstracts you away from XIB files. *XIB files are readable, and you can make sense of them. The structure of the XML isn't too complicated. However, the contents described by the XML structure are complicated. They're generated using a custom NSCoder. The XML is the output of the various NSCoding implementations that were used to create the file, and they're private to the classes that implemented them. The IBPlugin route is the way to go - Jon Hess (Ignore the huge blob of binary data at the bottom of the XIB, that's just a binary, runnable version of the stuff above it) *) Note that that is actually the hard part -- control sizes may differ so substantially, that it may be impossible to do a 1-on-1 translation of your UI automatically without making it look horrible. You may need a graphics designer with a good eye for layout to determine how these rects correspond. IMHO, most times you'll have to manually fix up things anyway, so you might as well go and recreate the UI and let IB's snap-to-guidelines do the job of initial layout.

So assume I'm trying to parse the following XML tag: titlePlanes, Trains, amp Automobiles/title When the parser enters the title node, it calls the createStructure callback function three times.

I understand that I need to do manual replacement of the amp with a in this case, but I still don't understand how I'm supposed to maintain the state in between the three calls to createStructure and addChild so that I can successfully concatenate all three text segments together to form the original string (which is what I want to store). I hope this makes sense - it's terribly frustrating. As always, thanks in advance. I haven't used CFXMLParser, but generally in event xml parsing you keep adding to the string until the end of the element. Parsers may break the element up into several parts and give them to you one at a time. Ya, I finally got fed up with the Core Foundation parser and switched to the Cocoa Event Driven parser.

I don't know why I didn't go with Cocoa in the first place. As soon as I decided to use the cocoa parser I had everything working perfectly within 3 minutes! Thanks for the help.

Interesting.. thanks for the solution. Naturally almost immediately
after I sent my original question to the list I figured out what was
wrong with my solution. The issue was with the format string..
Instead of a %x, I needed a %qx. The %qx displays a 64 bit address
whereas the %x displays a 32 bit address. When you give %x, only the
least significant 32 bits are printed and those happen to always be
the same (at least in my case).

In other words, you don't want the in front of myObject, which is giving you the address of a pointer variable rather than the value of the pointer.

NSTableView dragging to the finder - NSDragOperation
I have a subclass of NSTableView in which I'm implementing drag and drop to the
finder. Everything is basically working. However, when my class gets the call
draggedImage:endedAt:operation:, operation is NSDragOperationGeneric (for a
copy or move) or NSDragOperationDelete (for a delete). I'm expecting to get
NSDragOperationCopy, NSDragOperationMove or NSDragOperationDelete depending on
the modified keys and where the user dragged the image.
I am using NSFilesPromisePboardType for the pasteboard as the files are remote.
Here are some code snippets to answer some possible queries in advance...
- (NSDragOperation)draggingSourceOperationMaskForLocal:(BOOL)isLocal
{
if (isLocal) return NSDragOperationNone;
else return NSDragOperationCopy | NSDragOperationMove |
NSDragOperationDelete;
}
- (BOOL)ignoreModifierKeysWhileDragging
{
return NO;
}

How to specify a relative path to a (pdf)-document in a (pdf)-document
Dear list members, I am writing to you to ask for some help on specifying a path to a document, which I could not find by searching the web and the list. What I want to achieve is this: - Having a couple of hyperlinks in a PDF-document, that opens other PDF-documents on a CD-ROM by clicking on it. I found this website, where this kind of relative links are described for OpenOffice: http://www.oooninja.com/2008/02/create-relative-links-in-pdfs.html I know that in Acrobat you can specify a link to a document in relation to the document you put the link into, which is what I want to achieve. I this a specialty? I do not want to use Acrobat or OpenOffice to add the links, because I would have to add thousands of links by hand. Instead I can use Cocoa and some text editor to finish formating and finally print to pdf using Quartz Context or Adobe Acrobat. How I tried to tackle the problem: - I did create an rtf-file with a hyperlink to a file programatically and opened the file in e.g. MS Word and converted it to PDF using Adobe Acrobat. - I created an NSAttributed string and set a fileURL to the document using NSURL's fileURLwithPath: method and saved it to an rtf document, using NSData's dataFromRange: documentAtttributes method. This works, but the path is absolute, so there is no way of putting it onto a CD- ROM. Using baseURL does not seem to give me the option of specifying a file url, as well as somehow counteracts on reaching my aim: a baseURL is again an absolute path, which I will not find on a CD-ROM mounted on Windows or Linux-boxes or on Macs. So my question is how to reach my aim using a new approach? Any help is very much appreciated, thank you in advance.

Drawing Graphs in Cocoa
Hi, I'm working on an application where I need to draw graphs in Cocoa. I'm not talking about data plotting, I'm talking about creating visualizations for directed, acyclic graphs in the computer science / discrete math sense (where a graph is a collection of nodes and edges). Does anyone know of any abstractions on top of the low level Cocoa drawing APIs that support this? If not, is anyone interested in working with me on a mini project to create an open source library to do this? I would be able to lead the project, and I'd be looking to get it started in the next few weeks. The basic elements of the API would be: - a simple way to represent a graph in memory, and perhaps in persisted form (may already exist) - a NSView subclass to draw the graph I want the end programmer to be able to pass custom context information along with each graph node, and I want to make good use of delegates when writing the view so the end programmer can use that context information to customize the outcome (I'm thinking of things like colors, size of nodes, text labels, etc). I also want to abstract some aspects of user interaction with the graph, such as observing clicks on nodes and edges. As I said above, right now I am only interested in directed, acyclic graphs. However, for the long term, I see other needs arising in the community, so I expect the API to evolve over time.

NSTreeController rearrangeObjects doesn't always trigger sorting
I know that similar issues have been raised in the past, but I haven't been able to find a clear solution. I have a Core Data app with an NSOutlineView controlled by an entity- mode NSTreeController bound to the managed object context. The NSTreeController has sort descriptors based on certain attributes of the model object. Sorting does take place when the frameworks seem to think fit (for example when a document is opened), but if I call -rearrangeObjects to force a sort programmatically nothing happens. Actually, if I tick 'Uses Lazy Fetching' in the controller's IB attributes, the view will sort the first level of nodes, but not the deeper levels. Sorting was working fine in earlier versions of the OS. I'm now in 10.5.4 and I'm not certain which version introduced this problem. Any suggestions? I am conscious of the slightly strange wording of the documentation of this method, which is much less clear cut than that of the NSArrayController equivalent. It almost suggests that the method will only work in subclasses. If so, I don't understand why. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Efficient Updating of Thousands of NSManagedObject Relationships
Even building up an array of managedobjects and then passing that to the set returned from mutableSetValueForKey results in extremely long updates. For example, I just tried moving 1300 songs to a playlist and while it took almost no time to fetch each song from the managed context and build up the array, the following call took over a minute to execute: [[destinationList mutableSetValueForKey:@songs] addObjectsFromArray:songs]; When it completed the data was correct, but I have to imagine there's a much faster way to do this. As always, thanks for any help. Sincerely, Kenny On Jul 28, 2008, at 1:35 PM, I. Savant wrote: for (song in songs) NSManagedObject *song = ...

Re: sorting two arrays
The most logical is to make a class that has - as properties - the
two pieces of data being sorted, then put these in an NSArray (or
NSMutableArray as appropriate to your situation), and then sort that
instead. Not only will it sort both pieces of data together, but it's
a lot easier to extend if you need more data sorted along with the
key array.
So if array1 is an array of 'int', and array2 is an array of
'NSString *', then you would make a class like:
@interface sortableData : NSObject
{
int sortKey;
NSString *data;
}
// useful methods here...
@end
then - in your .m file - implement a sort method that takes an
'NSArray *' pointing to the array filled with references to
sortableData objects. Now, when you sort it, all the other data (the
NSStrings) come along for the ride for free.
The other way to do it is - when you do a swap() on one array's
elements i and j, you swap the elements i and j of (all) the other
array(s) related to the key value array (the one you're directly
sorting on.)
Finally, put the data into a database with an SQL front-end, and
do the sort that way.
That said, I hope you get it working. :)

Re: sorting two arrays
Jeff, This has a bit of a whiff about it. Two arrays of the same objects is not unusual, but forcing them always into the same order is - surely that's just a data duplication? If the arrays are meant to be identical, why not just use one array? What is different? If array B contains array A + some extra objects (which after sorting will always be pushed to the end of the array), maybe a better pattern would be to keep just these additional objects in array B and just tack them on to the end of array A when a complete list is requested. Then your problem reduces to how do I sort an array? which Cocoa gives you. A bit more of an overview of what you're actually trying to do would help. cheers, Graham On 29 Jul 2008, at 1:08 am, Jeff LaMarche wrote: Hey all...
