I've got a text field value bound to a key path that uses @sum. When the array controller is filtered, the text field updates properly, but extremely slowly, lagging the UI or outright beachballing after every key press (less so as the number of items in arrangedObjects decreases). There is no lag if I don't use @sum; I've narrowed it do...
Hi All, I have a NSArray of string id and a NSDictionary of NSDictionary objects. I am currently looping through the string id array to match the id value in the NSDictionary. There are around 200 NSDictionary objects and only 5 or so string ID. My current code is such: for (NSString *Str in aArr) { for (NSDictionary *a in ap...
Hi devs, I'm trying to build a microphone audio streamer to iPhone. The server software will be a mac desktop app and the client will be iPhone, and they are connected via tcp port. I've successfully connected the mac app and iPhone, and tried to send a fixed test.m4a audio file first. But at the iPhone i grabbed the data well, when t...
I save a NSBitmapImageRep to a BMP file (Snow Leopard). It seems ok when i open it on macos. But it makes an error on my multimedia device (which can show any BMP file from internet). I cannot figure out what is wrong, but when i look inside the file (with the cool hexfiend app on macos), 2 things wrong: the header have a wrong value ...

Hi All, Im trying to write a method that will pull out the ID from a URI String. My code below seems inefficient, what would be a better way of finding the id string? NSString *aID = [[[NSString alloc] initWithString:@"http://www.example.com/id368907840?mt=8&uo=4"] autorelease]; NSArray *arrStr = [aID componentsSeparatedByString:@"...
I'm wondering whether the merge=union option in .gitattributes makes sense for .pbxproj files. The manpage states for this option: Run 3-way file level merge for text files, but take lines from both versions, instead of leaving conflict markers. This tends to leave the added lines in the resulting file in random order and the user shoul...
Hello guys, How exactly filling bugs for the iPhone SDK with Apple works? I've always seen people mentioning we should fill bugs and duplicates is their way of measuring priority, but it's not clear to me: How to actually fill the bug; How to flag someone else's bug as a duplicate, and; What do I need to tell people I've filled that ...
I have a managed object ("A") that contains various attributes and types of relationships, and its relationships also have their own attributes & relationships. What I would like to do is to "copy" or "duplicate" the entire object graph rooted at object "A", and thus creating a new object "B" that is very similar to "A". To be more spec...
I am trying to reverse-engineer a preferences file (not for any nefarious purposes, just so that I can script usage of it) that, among other things, has arrays of coordinates stored within it. This is the salient snippet from the property list: <dict> <key>$class</key> <dict> <key>CF$UID</key> <integer>34</integer> </dict...
I want to iterate through all of the objects in my NSManagedObjectContext, and update them manually. Then, every managed object should be updated. What's the best way to do this? ...
I always have an EULA attached to my DMGs. But my users now can only see it the first time they download my application. Whenever they get an upgrade within the app through Sparkle framework, the EULA is not shown when the .dmg gets extracted by Sparkle. How can I make Sparkle show the EULA? ...

I would like to be able to gather info like how often certain windows are opened, what types of user data are accessed, how often menu items are clicked, etc. Does anyone know of a 3rd party (open source or commercial) Cocoa/Obj-C library or plugin that would allow me to gather this info? ...
I created a separate NSManagedObjectContext on a separate thread to perform some store maintenance. However, I have noticed that the context returns YES for hasChanges as soon as a managed object in it is even referenced e.g. NSString *name = managedObject.name; This context is created and used exclusively in 1 method. Why is it retur...
What's the rule of thumb if I want to change observed object's single property from different menu items (think - list of options). E.g. I have an app that displays a car in a single window. I have a menu with menu item that says [Colors] with few submenu items like [Black, Green, Blue, Red, White, etc.]. How do I implement the mechanis...
Hi, What is the best way to do view management in a multiview application? Right now I have this ViewSwitcher method/function that comes from a custom delegate I created. The code is a whole bunch of if else like this MyViewController *c = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; c.delegate...
I want to make a widget that displays a column of selectable text data. It seems that the NSBrowser is the best cocoa object to do this but I cannot figure out how to populate the NSBrowser with any sort of data. I assume I can set the string value of an NsBrowserCell but no where in the documentation can I find where to add a new cell...

How can I retrieve values only for one of the attributes, for example value "John" for attribute name="given_name" ? Thanks for answers. ...
Is there a standard Aqua way to handle a practically infinite document? For example, imagine a level editor for a tile-based game. The level has no preset size (though it's technically limited by NSInteger's size); tiles can be placed anywhere on the grid. Is there a standard interface for scrolling through such a document? I can't sim...
