NSNetService resolution and sleep
My app has a client component and a server component. The server publishes an NSNetService and the client discovers it using NSNetServiceBrowser. When the Mac goes to sleep the client NSNetServiceBrowser delegate receives - netServiceBrowser:didRemoveService:moreComing: When the Mac awakes the client NSNetServiceBrowser delegate receives: - netServiceBrowser:didFindService:moreComing: - netServiceBrowser:didRemoveService:moreComing: - netServiceBrowser:didFindService:moreComing: In other words the NSNetService instance appears, disappears and then reappears after sleep. I can deal with the sleep-remove + awake-find sequence okay but the extra service connection notifications are troublesome as it is hard to distinguish them from genuine service removal rather than an apparent side effect of sleep recuperation. Is this expected or do I need to configure the service in some way with regard to sleep performance? At present I simply let NSNetService do is it wills through the sleep. Maybe this one of those cases where one's own expectations are simply out of whack with the black box.

The only thing that infuriates me more than the time spent hunting down name collisions with private APIs is the insistence from some parties that ObjC namespaces are a solution in search of a problem. In a world with KVC/KVO where prefixing method names to ensure uniqueness is no longer feasible, Apple needs to deliver namespaces for ObjC. Hacks like private API begins with underscore aren't enough to deal with public/private namespace collisions or multiple similarly-named classes being loaded dynamically into the same process.

UITextField in UIScrollView
I have a number of UITextField objects inside a (subclass of) UIView, which is
the content view for a (subclass of) UIScrollView.
When the user types into a text field, I dynamically change its size if
necessary and reset the content size of the content view. When needed, I also
scroll so that a rectangle matching the typing position of the active text
field is visible in the scroll area. So far, so good.
When the content size is larger than the visible space and the user moves to an
empty UITextField to type, the display scrolls right and left on each
character. The problem is that scrollRectToVisible:: is being called from a
UIFieldEditor object with a rectangle that is the size of the entire content
area rather than anything related to the current field or the location where
characters are being entered.
Here's a bit of the traceback:
#0 -[MultiLineScrollView scrollRectToVisible:animated:] (self=0x4d2b810,
_cmd=0x6cddd5, rect={origin = {x = 0, y = 0}, size = {width = 1119, height =
740}}, animated=1 '\001')
#1 0x0035dd84 in -[UIFieldEditor scrollSelectionToVisible:] ()
#2 0x0035bc18 in -[UIFieldEditor webViewDidChange:] ()
#3 0x0001f6c1 in _nsnote_callback ()
#4 0x00d84f99 in __CFXNotificationPost_old ()
#5 0x00d0433a in _CFXNotificationPostNotification ()
#6 0x00015266 in -[NSNotificationCenter postNotificationName:object:userInfo:]

#7 0x00d1d67d in __invoking___ ()
#8 0x00d1d551 in -[NSInvocation invoke] ()
#9 0x0211982a in SendDelegateMessage ()
#10 0x01f6636f in WebEditorClient::respondToChangedContents ()
#11 0x02166fdc in WebCore::Editor::appliedEditing ()
I suppose I could set up a flag to ignore the call if I've already scrolled the
current text field or if the height suggests that it's *not* a text field, but
I'm interested in finding a way to handle this that isn't fighting with the
framework if at all possible.
(Also, strictly out of curiosity, what are WebCore, WebView, and
WebEditorClient things doing in a
UITextField?)___

Re: How to read a text file over a network
You should check out NSFileManager to see if you can simplify your read methods - specifically the contentsAtPath: method. Then decode the data from the file using the appropriate encoding. Once you've figured out what the URI for the file is, you can use NSFileManager again to fetch it, using an NSUrl. It sounds like you might have an easier time using a plist.

Re: Core Data: Error while saving. Multiple validation errors occurred.
When I log Userinfo from the save operation,
NSError *error = nil; //Now
try saving the data
if (![[self managedObjectContext] save: error]) {
NSLog(@Unresolved error %@, %@, error, [error userInfo]);
I get:

Any idea what is causing this
Usually it happens because you tried to add or modify several records at once
and did not push a value for a required property in more than one of them. I
think that error also happens if you left a dangling reference in a
relationship property for more than one record.
or where to look for a fix?
Check the error's userInfo for more information about what went wrong. The
userInfo dictionary will contain more specific information about what went
wrong.

That means that you added three keys to the model _and_ marked them as
required, and then the application failed to fill each of those keys with a
value prior to saving. Either you need to make the app fill those keys with
values, or you need to re-evaluate whether or not those keys should be required
to be filled change the model accordingly.

Re: Rotated and scaled CALayer
Hi Ramas, No I hadn't. I not quite sure which action (and how) I could use in addition with Core Animation. I need (near) real-time drawing for scaling and rotating. So dealing with pixels data for every update is quite expensive. Unless I am missing something? It is written in the basic documentation of the vImage framework that it was precisely done to support real-time or near real-time geometrical operations on raster files like rotation and interpolation. I must admit, however, that I never dug into it myself: I do a lot of CALayer affine transforms in the application I'm writing, but I don't care about rotated pixels since I mostly deal with vector data.

Hi everyone, This is a question, but more of an announcement. We're going to try and get the Silicon Valley CocoaHeads group up and running again, with our first meeting being January 13th at 7pm.

Intercepting cocoa/quartz/opengl Draw command.
Hi All, I am developing application that allows remote access to other applications (running on different machines). The idea is to make give users transparent access to certain applications. To have this , I am trying to intercept cocoa/quartz/opengl draw command and reproduce them in the client (The input is redirected from the client to the server). But unable to figure out the way to get draw command. On Windows , this can be done by using Windows metafile which captures all GDI drawing commands to a file and that file can then be passed to a remote PC and rendered there . Is there any such file on mac which stores all drawing commands ? OR Is there any other way to develop above application. Please give me your valuable suggestion. Thanks in advance.

Core data - binding related problem in NSNumberFormatter and NSDatePicker
Hi all, I am trying a core-data sample application, from Cocoa Programming - Aaron Hillegass. In it there is an entity Car, with following properties: 1. condition - Int 16 2. datePurchased - Date 3. makeModel - String 4. onSpecial - Boolean 5. photo - Binary 6. price - Decimal There are certain view objects such as- 1. TableView 2. DatePicker 3. Image Well, etc. Some of the bindings performed are- 1. TableView - TableColumn with NSNumberFormatter (set as currency) - value: arrangedObjects.price 2. DatePicker - value: selection.datePurchased Problems are: 1. In TableColumn with NSNumberFormatter it is not accepting any decimal numbers which I am entering for currency, such as - 123,00 or 123.45 or +235 or 567. It is always displaying this alert message: Formatting error. 2. Whenever I am selecting a row in table and changing its corresponding value in date picker, it is simultaneously changing the values for other records, ie. if for first row in table I have set it to 12/25/2004, it is keeping it 12/25/2004 for other rows. Can anyone help me to resolve my problems?

The idea is to make give users transparent access to certain applications. To have this , I am trying to intercept cocoa/quartz/opengl draw command and reproduce them in the client (The input is redirected from the client to the server). But unable to figure out the way to get draw command. On Windows , this can be done by using Windows metafile which captures all GDI drawing commands to a file and that file can then be passed to a remote PC and rendered there . Is there any such file on mac which stores all drawing commands ? OR Is there any other way to develop above application. I'd start by looking at the source code to VineServer and figuring out how they did it: http://sourceforge.net/projects/osxvnc/ Also, please don't cross-post.
