Hey I have been battling with this problem for a while now. Perhaps there is something I am missing in knowledge about multi threading but here is what happens. When I create an nsoperation queue any variables that are allocated become cleared after the "[request startSynchronous];" line of code. Here is what I'm talking about: @impleme...
After always running monolithic blocks of code from within my AppController object, I've just learned how to modularize my code using separate model controller objects (so much neater and less confusing to work with :-)) My simple test app has a main AppController and two model objects (Model1 and Model2). I can successfully pass data f...
I am writing a core data Cocoa application in which there are accounts and transactions (monetary). The account entity description contains a balance attribute.

I'm working on a relatively simple iPhone application that has a multi-round Timer with a number of settings such as the number of rounds and round length. We allow certain settings to be upated while the timer is running which means the timer may be reading from the same memory that the settings are writing. There are no critical sect...

Hi, I'd like to create a terminal emulator for Mac OS X. The problem is: I have no idea where to start. Can I just use a whole bunch of NSTasks? Or do I have to read through tons of source code for programs like xterm, urxvt, etc? I don't want a lot of customizability (= no config file parsing), nor complex features, and I'm only gonna ...
I'm looking for a way to reorder an NSOperationQueue. I could cancel all the operations and toss them back in using the order I want, but I was hoping for something a little bit cleaner. Any thoughts? ...
Hi, How can I store a variable of type int32_t (e.g. for ABPropertyID) in an NSDictionary? [NSNumber numberWithInt:...] doesn't seem to work.

Hi, I've a table view to which I add columns dynamically. It must be done this way because I can't predict how many or which columns I will need. Some columns are checkboxes but I can't click on them when I run my application. The column and checkbox are set to be editable but if I click on the checkbox the check won't get set. Am I m...
Hi I am trying to create a table-view programatically using a cocoa lisp bridge called clozure CL. Now I doubt many people are familiar with this package so I will not go into specifics of my code but I am getting some very strange errors when I try to call addSubview to add my tableView to my window. I have initialized it using InitWi...
Is it possible to detect actions that tell my controller when the user is mousing (or otherwise perusing) the items in an NSPopUpButton? I only seem to be notified on a new selection and I'd like to be notified as the user is rolling over any item in the menu. thanks tom ...
Hey Guys! I'm stuck! I am trying to create a custom modal dialog. I would like it to perform similarly to the NSSavePanel using a block as a completion handler. I've copied only the important snippets I think are needed. @implementation ModalWindowController - (void)makeKeyAndOrderFront:(id)sender modalToWindow...
As the title says, some URLs take less than a second to load in the browser, but in my cocoa app, running the following line repeatedly results in initWithContentsOfURL sometimes taking up to 30 seconds to load the URL. What may be the source of this problem? I'm calling it like this: NSXMLDocument* aDoc = [[NSXMLDocument alloc] initWi...
I'm looking for a way to invert arbitrary NSColor values at runtime, and there doesn't appear to be any built-in method to do so. I will be using a category to extend NSColor as follows: NSColor * invertedColor = [someOtherColor inverted]; Here is the category method prototype that I am using: @implementation NSColor (MyCategories) ...
I'm writing a Cocoa app. One dialog has 3 tabs, some of the tabs needs more loading time, so I want to load them lazily. Since each Tab is a NSTabViewItem class, so I'm trying to derive from it and overriding its view property. In the view getter method, I use a ViewController to load a view and returns out. In Debugging, I found NSTabVi...
